Initialize 

procedure Initialize 
(Buffer: not null access Gtk_Text_Buffer_Record'Class;
Table: Gtk.Text_Tag_Table.Gtk_Text_Tag_Table := null);
Creates a new text buffer. "table": a tag table, or null to create a new one

Gtk_Text_Buffer_New 

function Gtk_Text_Buffer_New 
(Table: Gtk.Text_Tag_Table.Gtk_Text_Tag_Table := null) return Gtk_Text_Buffer;
Creates a new text buffer. "table": a tag table, or null to create a new one

Get_Type 

function Get_Type return Glib.GType;

Add_Mark 

procedure Add_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Mark: not null access Gtk.Text_Mark.Gtk_Text_Mark_Record'Class;
Where: Gtk.Text_Iter.Gtk_Text_Iter);
Adds the mark at position Where. The mark must not be added to another buffer, and if its name is not null then there must not be another mark in the buffer with the same name. Emits the "mark-set" signal as notification of the mark's initial placement. Since: gtk+ 2.12 "mark": the mark to add "where": location to place mark

Add_Selection_Clipboard 

procedure Add_Selection_Clipboard 
(Buffer: not null access Gtk_Text_Buffer_Record;
Clipboard: not null access Gtk.Clipboard.Gtk_Clipboard_Record'Class);
Adds Clipboard to the list of clipboards in which the selection contents of Buffer are available. In most cases, Clipboard will be the Gtk.Clipboard.Gtk_Clipboard of type GDK_SELECTION_PRIMARY for a view of Buffer. "clipboard": a Gtk.Clipboard.Gtk_Clipboard

Apply_Tag 

procedure Apply_Tag 
(Buffer: not null access Gtk_Text_Buffer_Record;
Tag: not null access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Emits the "apply-tag" signal on Buffer. The default handler for the signal applies Tag to the given range. Start and End do not have to be in order. "tag": a Gtk.Text_Tag.Gtk_Text_Tag "start": one bound of range to be tagged "end": other bound of range to be tagged

Apply_Tag_By_Name 

procedure Apply_Tag_By_Name 
(Buffer: not null access Gtk_Text_Buffer_Record;
Name: UTF8_String;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Calls Gtk.Text_Tag_Table.Lookup on the buffer's tag table to get a Gtk.Text_Tag.Gtk_Text_Tag, then calls Gtk.Text_Buffer.Apply_Tag. "name": name of a named Gtk.Text_Tag.Gtk_Text_Tag "start": one bound of range to be tagged "end": other bound of range to be tagged

Backspace 

function Backspace 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Interactive: Boolean;
Default_Editable: Boolean) return Boolean;
Performs the appropriate action as if the user hit the delete key with the cursor at the position specified by Iter. In the normal case a single character will be deleted, but when combining accents are involved, more than one character can be deleted, and when precomposed character and accent combinations are involved, less than one character will be deleted. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, the Iter will be re-initialized to point to the location where text was deleted. Since: gtk+ 2.6 "iter": a position in Buffer "interactive": whether the deletion is caused by user interaction "default_editable": whether the buffer is editable by default

Begin_User_Action 

procedure Begin_User_Action 
(Buffer: not null access Gtk_Text_Buffer_Record);
Called to indicate that the buffer operations between here and a call to Gtk.Text_Buffer.End_User_Action are part of a single user-visible operation. The operations between Gtk.Text_Buffer.Begin_User_Action and Gtk.Text_Buffer.End_User_Action can then be grouped when creating an undo stack. Gtk.Text_Buffer.Gtk_Text_Buffer maintains a count of calls to Gtk.Text_Buffer.Begin_User_Action that have not been closed with a call to Gtk.Text_Buffer.End_User_Action, and emits the "begin-user-action" and "end-user-action" signals only for the outermost pair of calls. This allows you to build user actions from other user actions. The "interactive" buffer mutation functions, such as Gtk.Text_Buffer.Insert_Interactive, automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if you user action consists solely of a single call to one of those functions.

Copy_Clipboard 

procedure Copy_Clipboard 
(Buffer: not null access Gtk_Text_Buffer_Record;
Clipboard: not null access Gtk.Clipboard.Gtk_Clipboard_Record'Class);
Copies the currently-selected text to a clipboard. "clipboard": the Gtk.Clipboard.Gtk_Clipboard object to copy to

Create_Child_Anchor 

function Create_Child_Anchor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter) return Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor;
This is a convenience function which simply creates a child anchor with Gtk.Text_Child_Anchor.Gtk_New and inserts it into the buffer with Gtk.Text_Buffer.Insert_Child_Anchor. The new anchor is owned by the buffer; no reference count is returned to the caller of Gtk.Text_Buffer.Create_Child_Anchor. "iter": location in the buffer

Create_Mark 

function Create_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Mark_Name: UTF8_String := "";
Where: Gtk.Text_Iter.Gtk_Text_Iter;
Left_Gravity: Boolean := True) return Gtk.Text_Mark.Gtk_Text_Mark;
Creates a mark at position Where. If Mark_Name is null, the mark is anonymous; otherwise, the mark can be retrieved by name using Gtk.Text_Buffer.Get_Mark. If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity (Left_Gravity = False), the mark will end up on the right of newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing). The caller of this function does *not* own a reference to the returned Gtk.Text_Mark.Gtk_Text_Mark, so you can ignore the return value if you like. Marks are owned by the buffer and go away when the buffer does. Emits the "mark-set" signal as notification of the mark's initial placement. "mark_name": name for mark, or null "where": location to place mark "left_gravity": whether the mark has left gravity

Cut_Clipboard 

procedure Cut_Clipboard 
(Buffer: not null access Gtk_Text_Buffer_Record;
Clipboard: not null access Gtk.Clipboard.Gtk_Clipboard_Record'Class;
Default_Editable: Boolean);
Copies the currently-selected text to a clipboard, then deletes said text if it's editable. "clipboard": the Gtk.Clipboard.Gtk_Clipboard object to cut to "default_editable": default editability of the buffer

Delete 

procedure Delete 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: in out Gtk.Text_Iter.Gtk_Text_Iter;
The_End: in out Gtk.Text_Iter.Gtk_Text_Iter);
Deletes text between Start and End. The order of Start and End is not actually relevant; Gtk.Text_Buffer.Delete will reorder them. This function actually emits the "delete-range" signal, and the default handler of that signal deletes the text. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, the Start and End will be re-initialized to point to the location where text was deleted. "start": a position in Buffer "end": another position in Buffer

Delete_Interactive 

procedure Delete_Interactive 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start_Iter: Gtk.Text_Iter.Gtk_Text_Iter;
End_Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Default_Editable: Boolean;
Result: out Boolean);
Deletes all *editable* text in the given range. Calls Gtk.Text_Buffer.Delete for each editable sub-range of [Start,End). Start and End are revalidated to point to the location of the last deleted range, or left untouched if no text was deleted. "start_iter": start of range to delete "end_iter": end of range "default_editable": whether the buffer is editable by default

Delete_Mark 

procedure Delete_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Mark: not null access Gtk.Text_Mark.Gtk_Text_Mark_Record'Class);
Deletes Mark, so that it's no longer located anywhere in the buffer. Removes the reference the buffer holds to the mark, so if you haven't called g_object_ref on the mark, it will be freed. Even if the mark isn't freed, most operations on Mark become invalid, until it gets added to a buffer again with Gtk.Text_Buffer.Add_Mark. Use Gtk.Text_Mark.Get_Deleted to find out if a mark has been removed from its buffer. The "mark-deleted" signal will be emitted as notification after the mark is deleted. "mark": a Gtk.Text_Mark.Gtk_Text_Mark in Buffer

Delete_Mark_By_Name 

procedure Delete_Mark_By_Name 
(Buffer: not null access Gtk_Text_Buffer_Record;
Name: UTF8_String);
Deletes the mark named Name; the mark must exist. See Gtk.Text_Buffer.Delete_Mark for details. "name": name of a mark in Buffer

Delete_Selection 

function Delete_Selection 
(Buffer: not null access Gtk_Text_Buffer_Record;
Interactive: Boolean;
Default_Editable: Boolean) return Boolean;
Deletes the range between the "insert" and "selection_bound" marks, that is, the currently-selected text. If Interactive is True, the editability of the selection will be considered (users can't delete uneditable text). "interactive": whether the deletion is caused by user interaction "default_editable": whether the buffer is editable by default

Deserialize_Get_Can_Create_Tags 

function Deserialize_Get_Can_Create_Tags 
(Buffer: not null access Gtk_Text_Buffer_Record;
Format: Gdk.Types.Gdk_Atom) return Boolean;
This functions returns the value set with Gtk.Text_Buffer.Deserialize_Set_Can_Create_Tags Since: gtk+ 2.10 "format": a Gdk.Types.Gdk_Atom representing a registered rich text format

Deserialize_Set_Can_Create_Tags 

procedure Deserialize_Set_Can_Create_Tags 
(Buffer: not null access Gtk_Text_Buffer_Record;
Format: Gdk.Types.Gdk_Atom;
Can_Create_Tags: Boolean);
Use this function to allow a rich text deserialization function to create new tags in the receiving buffer. Note that using this function is almost always a bad idea, because the rich text functions you register should know how to map the rich text format they handler to your text buffers set of tags. The ability of creating new (arbitrary!) tags in the receiving buffer is meant for special rich text formats like the internal one that is registered using Gtk.Text_Buffer.Register_Deserialize_Tagset, because that format is essentially a dump of the internal structure of the source buffer, including its tag names. You should allow creation of tags only if you know what you are doing, e.g. if you defined a tagset name for your application suite's text buffers and you know that it's fine to receive new tags from these buffers, because you know that your application can handle the newly created tags. Since: gtk+ 2.10 "format": a Gdk.Types.Gdk_Atom representing a registered rich text format "can_create_tags": whether deserializing this format may create tags

End_User_Action 

procedure End_User_Action 
(Buffer: not null access Gtk_Text_Buffer_Record);
Should be paired with a call to Gtk.Text_Buffer.Begin_User_Action. See that function for a full explanation.

Get_Bounds 

procedure Get_Bounds 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: out Gtk.Text_Iter.Gtk_Text_Iter;
The_End: out Gtk.Text_Iter.Gtk_Text_Iter);
Retrieves the first and last iterators in the buffer, i.e. the entire buffer lies within the range [Start,End). "start": iterator to initialize with first position in the buffer "end": iterator to initialize with the end iterator

Get_Char_Count 

function Get_Char_Count 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gint;
Gets the number of characters in the buffer; note that characters and bytes are not the same, you can't e.g. expect the contents of the buffer in string form to be this many bytes long. The character count is cached, so this function is very fast.

Get_Copy_Target_List 

function Get_Copy_Target_List 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gtk.Target_List.Gtk_Target_List;
This function returns the list of targets this text buffer can provide for copying and as DND source. The targets in the list are added with %info values from the Gtk_Text_Buffer_Target_Info enum, using gtk_target_list_add_rich_text_targets and Gtk.Target_List.Add_Text_Targets. Since: gtk+ 2.10

Get_End_Iter 

procedure Get_End_Iter 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter);
Initializes Iter with the "end iterator," one past the last valid character in the text buffer. If dereferenced with Gtk.Text_Iter.Get_Char, the end iterator has a character value of 0. The entire buffer lies in the range from the first position in the buffer (call Gtk.Text_Buffer.Get_Start_Iter to get character position 0) to the end iterator. "iter": iterator to initialize

Get_Has_Selection 

function Get_Has_Selection 
(Buffer: not null access Gtk_Text_Buffer_Record) return Boolean;
Indicates whether the buffer has some text currently selected. Since: gtk+ 2.10

Get_Insert 

function Get_Insert 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gtk.Text_Mark.Gtk_Text_Mark;
Returns the mark that represents the cursor (insertion point). Equivalent to calling Gtk.Text_Buffer.Get_Mark to get the mark named "insert", but very slightly more efficient, and involves less typing.

Insert 

procedure Insert 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: in out Gtk.Text_Iter.Gtk_Text_Iter;
Text: UTF8_String);
Inserts Len bytes of Text at position Iter. If Len is -1, Text must be nul-terminated and will be inserted in its entirety. Emits the "insert-text" signal; insertion actually occurs in the default handler for the signal. Iter is invalidated when insertion occurs (because the buffer contents change), but the default signal handler revalidates it to point to the end of the inserted text. "iter": a position in the buffer "text": text in UTF-8 format

Get_Iter_At_Child_Anchor 

procedure Get_Iter_At_Child_Anchor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Anchor: not null access Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor_Record'Class);
Obtains the location of Anchor within Buffer. "iter": an iterator to be initialized "anchor": a child anchor that appears in Buffer

Get_Iter_At_Line 

procedure Get_Iter_At_Line 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Line_Number: Gint);
Initializes Iter to the start of the given line. "iter": iterator to initialize "line_number": line number counting from 0

Get_Iter_At_Line_Index 

procedure Get_Iter_At_Line_Index 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Line_Number: Gint;
Byte_Index: Gint);
Obtains an iterator pointing to Byte_Index within the given line. Byte_Index must be the start of a UTF-8 character, and must not be beyond the end of the line. Note *bytes*, not characters; UTF-8 may encode one character as multiple bytes. "iter": iterator to initialize "line_number": line number counting from 0 "byte_index": byte index from start of line

Get_Iter_At_Line_Offset 

procedure Get_Iter_At_Line_Offset 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Line_Number: Gint;
Char_Offset: Gint);
Obtains an iterator pointing to Char_Offset within the given line. The Char_Offset must exist, offsets off the end of the line are not allowed. Note *characters*, not bytes; UTF-8 may encode one character as multiple bytes. "iter": iterator to initialize "line_number": line number counting from 0 "char_offset": char offset from start of line

Get_Iter_At_Mark 

procedure Get_Iter_At_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Mark: not null access Gtk.Text_Mark.Gtk_Text_Mark_Record'Class);
Initializes Iter with the current position of Mark. "iter": iterator to initialize "mark": a Gtk.Text_Mark.Gtk_Text_Mark in Buffer

Get_Iter_At_Offset 

procedure Get_Iter_At_Offset 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter;
Char_Offset: Gint);
Initializes Iter to a position Char_Offset chars from the start of the entire buffer. If Char_Offset is -1 or greater than the number of characters in the buffer, Iter is initialized to the end iterator, the iterator one past the last valid character in the buffer. "iter": iterator to initialize "char_offset": char offset from start of buffer, counting from 0, or -1

Get_Line_Count 

function Get_Line_Count 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gint;
Obtains the number of lines in the buffer. This value is cached, so the function is very fast.

Get_Mark 

function Get_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Name: UTF8_String) return Gtk.Text_Mark.Gtk_Text_Mark;
Returns the mark named Name in buffer Buffer, or null if no such mark exists in the buffer. "name": a mark name

Get_Modified 

function Get_Modified 
(Buffer: not null access Gtk_Text_Buffer_Record) return Boolean;
Indicates whether the buffer has been modified since the last call to Gtk.Text_Buffer.Set_Modified set the modification flag to False. Used for example to enable a "save" function in a text editor.

Set_Modified 

procedure Set_Modified 
(Buffer: not null access Gtk_Text_Buffer_Record;
Setting: Boolean);
Used to keep track of whether the buffer has been modified since the last time it was saved. Whenever the buffer is saved to disk, call gtk_text_buffer_set_modified (Buffer, FALSE). When the buffer is modified, it will automatically toggled on the modified bit again. When the modified bit flips, the buffer emits a "modified-changed" signal. "setting": modification flag setting

Get_Paste_Target_List 

function Get_Paste_Target_List 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gtk.Target_List.Gtk_Target_List;
This function returns the list of targets this text buffer supports for pasting and as DND destination. The targets in the list are added with %info values from the Gtk_Text_Buffer_Target_Info enum, using gtk_target_list_add_rich_text_targets and Gtk.Target_List.Add_Text_Targets. Since: gtk+ 2.10

Get_Selection_Bound 

function Get_Selection_Bound 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gtk.Text_Mark.Gtk_Text_Mark;
Returns the mark that represents the selection bound. Equivalent to calling Gtk.Text_Buffer.Get_Mark to get the mark named "selection_bound", but very slightly more efficient, and involves less typing. The currently-selected text in Buffer is the region between the "selection_bound" and "insert" marks. If "selection_bound" and "insert" are in the same place, then there is no current selection. Gtk.Text_Buffer.Get_Selection_Bounds is another convenient function for handling the selection, if you just want to know whether there's a selection and what its bounds are.

Get_Selection_Bounds 

procedure Get_Selection_Bounds 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: out Gtk.Text_Iter.Gtk_Text_Iter;
The_End: out Gtk.Text_Iter.Gtk_Text_Iter;
Result: out Boolean);
Returns True if some text is selected; places the bounds of the selection in Start and End (if the selection has length 0, then Start and End are filled in with the same value). Start and End will be in ascending order. If Start and End are NULL, then they are not filled in, but the return value still indicates whether text is selected. "start": iterator to initialize with selection start "end": iterator to initialize with selection end

Get_Slice 

function Get_Slice 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter;
Include_Hidden_Chars: Boolean := False) return UTF8_String;
Returns the text in the range [Start,End). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if Include_Hidden_Chars is False. The returned string includes a 0xFFFC character whenever the buffer contains embedded images, so byte and character indexes into the returned string *do* correspond to byte and character indexes into the buffer. Contrast with Gtk.Text_Buffer.Get_Text. Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer. "start": start of a range "end": end of a range "include_hidden_chars": whether to include invisible text

Get_Start_Iter 

procedure Get_Start_Iter 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: out Gtk.Text_Iter.Gtk_Text_Iter);
Initialized Iter with the first position in the text buffer. This is the same as using Gtk.Text_Buffer.Get_Iter_At_Offset to get the iter at character offset 0. "iter": iterator to initialize

Get_Tag_Table 

function Get_Tag_Table 
(Buffer: not null access Gtk_Text_Buffer_Record) return Gtk.Text_Tag_Table.Gtk_Text_Tag_Table;
Get the Gtk.Text_Tag_Table.Gtk_Text_Tag_Table associated with this buffer.

Get_Text 

function Get_Text 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter;
Include_Hidden_Chars: Boolean := False) return UTF8_String;
Returns the text in the range [Start,End). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if Include_Hidden_Chars is False. Does not include characters representing embedded images, so byte and character indexes into the returned string do *not* correspond to byte and character indexes into the buffer. Contrast with Gtk.Text_Buffer.Get_Slice. "start": start of a range "end": end of a range "include_hidden_chars": whether to include invisible text

Set_Text 

procedure Set_Text 
(Buffer: not null access Gtk_Text_Buffer_Record;
Text: UTF8_String);
Deletes current contents of Buffer, and inserts Text instead. If Len is -1, Text must be nul-terminated. Text must be valid UTF-8. "text": UTF-8 text to insert

Insert_At_Cursor 

procedure Insert_At_Cursor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Text: UTF8_String);
Simply calls Gtk.Text_Buffer.Insert, using the current cursor position as the insertion point. "text": text in UTF-8 format

Insert_Child_Anchor 

procedure Insert_Child_Anchor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Anchor: not null access Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor_Record'Class);
Inserts a child widget anchor into the text buffer at Iter. The anchor will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode "object replacement character" 0xFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for child anchors, but the "text" variants do not. E.g. see Gtk.Text_Buffer.Get_Slice and Gtk.Text_Buffer.Get_Text. Consider Gtk.Text_Buffer.Create_Child_Anchor as a more convenient alternative to this function. The buffer will add a reference to the anchor, so you can unref it after insertion. "iter": location to insert the anchor "anchor": a Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor

Insert_Interactive 

function Insert_Interactive 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: access Gtk.Text_Iter.Gtk_Text_Iter;
Text: UTF8_String;
Default_Editable: Boolean) return Boolean;
Like Gtk.Text_Buffer.Insert, but the insertion will not occur if Iter is at a non-editable location in the buffer. Usually you want to prevent insertions at ineditable locations if the insertion results from a user action (is interactive). Default_Editable indicates the editability of text that doesn't have a tag affecting editability applied to it. Typically the result of Gtk.Text_View.Get_Editable is appropriate here. "iter": a position in Buffer "text": some UTF-8 text "default_editable": default editability of buffer

Insert_Interactive_At_Cursor 

function Insert_Interactive_At_Cursor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Text: UTF8_String;
Default_Editable: Boolean) return Boolean;
Calls Gtk.Text_Buffer.Insert_Interactive at the cursor position. Default_Editable indicates the editability of text that doesn't have a tag affecting editability applied to it. Typically the result of Gtk.Text_View.Get_Editable is appropriate here. "text": text in UTF-8 format "default_editable": default editability of buffer

Insert_Pixbuf 

procedure Insert_Pixbuf 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Pixbuf: not null access Gdk.Pixbuf.Gdk_Pixbuf_Record'Class);
Inserts an image into the text buffer at Iter. The image will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode "object replacement character" 0xFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for pixbufs, but the "text" variants do not. e.g. see Gtk.Text_Buffer.Get_Slice and Gtk.Text_Buffer.Get_Text. "iter": location to insert the pixbuf "pixbuf": a Gdk.Pixbuf.Gdk_Pixbuf

Insert_Range 

procedure Insert_Range 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Copies text, tags, and pixbufs between Start and End (the order of Start and End doesn't matter) and inserts the copy at Iter. Used instead of simply getting/inserting text because it preserves images and tags. If Start and End are in a different buffer from Buffer, the two buffers must share the same tag table. Implemented via emissions of the insert_text and apply_tag signals, so expect those. "iter": a position in Buffer "start": a position in a Gtk.Text_Buffer.Gtk_Text_Buffer "end": another position in the same buffer as Start

Insert_Range_Interactive 

function Insert_Range_Interactive 
(Buffer: not null access Gtk_Text_Buffer_Record;
Iter: Gtk.Text_Iter.Gtk_Text_Iter;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter;
Default_Editable: Boolean) return Boolean;
Same as Gtk.Text_Buffer.Insert_Range, but does nothing if the insertion point isn't editable. The Default_Editable parameter indicates whether the text is editable at Iter if no tags enclosing Iter affect editability. Typically the result of Gtk.Text_View.Get_Editable is appropriate here. "iter": a position in Buffer "start": a position in a Gtk.Text_Buffer.Gtk_Text_Buffer "end": another position in the same buffer as Start "default_editable": default editability of the buffer

Move_Mark 

procedure Move_Mark 
(Buffer: not null access Gtk_Text_Buffer_Record;
Mark: not null access Gtk.Text_Mark.Gtk_Text_Mark_Record'Class;
Where: Gtk.Text_Iter.Gtk_Text_Iter);
Moves Mark to the new location Where. Emits the "mark-set" signal as notification of the move. "mark": a Gtk.Text_Mark.Gtk_Text_Mark "where": new location for Mark in Buffer

Move_Mark_By_Name 

procedure Move_Mark_By_Name 
(Buffer: not null access Gtk_Text_Buffer_Record;
Name: UTF8_String;
Where: Gtk.Text_Iter.Gtk_Text_Iter);
Moves the mark named Name (which must exist) to location Where. See Gtk.Text_Buffer.Move_Mark for details. "name": name of a mark "where": new location for mark

Paste_Clipboard 

procedure Paste_Clipboard 
(Buffer: not null access Gtk_Text_Buffer_Record;
Clipboard: not null access Gtk.Clipboard.Gtk_Clipboard_Record'Class;
Default_Editable: Boolean := True);
Pastes the contents of a clipboard at the insertion point, or at Override_Location. (Note: pasting is asynchronous, that is, we'll ask for the paste data and return, and at some point later after the main loop runs, the paste data will be inserted.) "clipboard": the Gtk.Clipboard.Gtk_Clipboard to paste from "default_editable": whether the buffer is editable by default

Place_Cursor 

procedure Place_Cursor 
(Buffer: not null access Gtk_Text_Buffer_Record;
Where: Gtk.Text_Iter.Gtk_Text_Iter);
This function moves the "insert" and "selection_bound" marks simultaneously. If you move them to the same place in two steps with Gtk.Text_Buffer.Move_Mark, you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized. "where": where to put the cursor

Register_Deserialize_Tagset 

function Register_Deserialize_Tagset 
(Buffer: not null access Gtk_Text_Buffer_Record;
Tagset_Name: UTF8_String := "") return Gdk.Types.Gdk_Atom;
This function registers GTK+'s internal rich text serialization format with the passed Buffer. See Gtk.Text_Buffer.Register_Serialize_Tagset for details. Since: gtk+ 2.10 "tagset_name": an optional tagset name, on null

Register_Serialize_Tagset 

function Register_Serialize_Tagset 
(Buffer: not null access Gtk_Text_Buffer_Record;
Tagset_Name: UTF8_String := "") return Gdk.Types.Gdk_Atom;
This function registers GTK+'s internal rich text serialization format with the passed Buffer. The internal format does not comply to any standard rich text format and only works between Gtk.Text_Buffer.Gtk_Text_Buffer instances. It is capable of serializing all of a text buffer's tags and embedded pixbufs. This function is just a wrapper around gtk_text_buffer_register_serialize_format. The mime type used for registering is "application/x-gtk-text-buffer-rich-text", or "application/x-gtk-text-buffer-rich-text;format=Tagset_Name" if a Tagset_Name was passed. The Tagset_Name can be used to restrict the transfer of rich text to buffers with compatible sets of tags, in order to avoid unknown tags from being pasted. It is probably the common case to pass an identifier != null here, since the null tagset requires the receiving buffer to deal with with pasting of arbitrary tags. Since: gtk+ 2.10 "tagset_name": an optional tagset name, on null

Remove_All_Tags 

procedure Remove_All_Tags 
(Buffer: not null access Gtk_Text_Buffer_Record;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Removes all tags in the range between Start and End. Be careful with this function; it could remove tags added in code unrelated to the code you're currently writing. That is, using this function is probably a bad idea if you have two or more unrelated code sections that add tags. "start": one bound of range to be untagged "end": other bound of range to be untagged

Remove_Selection_Clipboard 

procedure Remove_Selection_Clipboard 
(Buffer: not null access Gtk_Text_Buffer_Record;
Clipboard: not null access Gtk.Clipboard.Gtk_Clipboard_Record'Class);
Removes a Gtk.Clipboard.Gtk_Clipboard added with Gtk.Text_Buffer.Add_Selection_Clipboard. "clipboard": a Gtk.Clipboard.Gtk_Clipboard added to Buffer by Gtk.Text_Buffer.Add_Selection_Clipboard

Remove_Tag 

procedure Remove_Tag 
(Buffer: not null access Gtk_Text_Buffer_Record;
Tag: not null access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Emits the "remove-tag" signal. The default handler for the signal removes all occurrences of Tag from the given range. Start and End don't have to be in order. "tag": a Gtk.Text_Tag.Gtk_Text_Tag "start": one bound of range to be untagged "end": other bound of range to be untagged

Remove_Tag_By_Name 

procedure Remove_Tag_By_Name 
(Buffer: not null access Gtk_Text_Buffer_Record;
Name: UTF8_String;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter);
Calls Gtk.Text_Tag_Table.Lookup on the buffer's tag table to get a Gtk.Text_Tag.Gtk_Text_Tag, then calls Gtk.Text_Buffer.Remove_Tag. "name": name of a Gtk.Text_Tag.Gtk_Text_Tag "start": one bound of range to be untagged "end": other bound of range to be untagged

Select_Range 

procedure Select_Range 
(Buffer: not null access Gtk_Text_Buffer_Record;
Ins: Gtk.Text_Iter.Gtk_Text_Iter;
Bound: Gtk.Text_Iter.Gtk_Text_Iter);
This function moves the "insert" and "selection_bound" marks simultaneously. If you move them in two steps with Gtk.Text_Buffer.Move_Mark, you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized. Since: gtk+ 2.4 "ins": where to put the "insert" mark "bound": where to put the "selection_bound" mark

Unregister_Deserialize_Format 

procedure Unregister_Deserialize_Format 
(Buffer: not null access Gtk_Text_Buffer_Record;
Format: Gdk.Types.Gdk_Atom);
This function unregisters a rich text format that was previously registered using gtk_text_buffer_register_deserialize_format or Gtk.Text_Buffer.Register_Deserialize_Tagset. Since: gtk+ 2.10 "format": a Gdk.Types.Gdk_Atom representing a registered rich text format.

Unregister_Serialize_Format 

procedure Unregister_Serialize_Format 
(Buffer: not null access Gtk_Text_Buffer_Record;
Format: Gdk.Types.Gdk_Atom);
This function unregisters a rich text format that was previously registered using gtk_text_buffer_register_serialize_format or Gtk.Text_Buffer.Register_Serialize_Tagset Since: gtk+ 2.10 "format": a Gdk.Types.Gdk_Atom representing a registered rich text format.

Insert 

procedure Insert 
(Buffer: access Gtk_Text_Buffer_Record;
Iter: in out Gtk.Text_Iter.Gtk_Text_Iter;
Text: Gtkada.Types.Chars_Ptr);
More efficient version of Insert, which doesn't require a string copy.

Insert_At_Cursor 

procedure Insert_At_Cursor 
(Buffer: access Gtk_Text_Buffer_Record;
Text: Gtkada.Types.Chars_Ptr;
Len: Gint := -1);
Call Buffer_Insert, using the current cursor position as the insertion point. Text: UTF-8 format C string to insert.

Get_Text 

function Get_Text 
(Buffer: access Gtk_Text_Buffer_Record;
Start: Gtk.Text_Iter.Gtk_Text_Iter;
The_End: Gtk.Text_Iter.Gtk_Text_Iter;
Include_Hidden_Chars: Boolean := False) return Gtkada.Types.Chars_Ptr;
Same as Get_Text above, but return a pointer to a C string, for efficiency. The caller is responsible for freeing (using Gtkada.Types.g_free) the returned pointer.

Selection_Exists 

function Selection_Exists 
(Buffer: access Gtk_Text_Buffer_Record) return Boolean;
Return True if some text in the buffer is currently selected.

Insert_With_Tags 

procedure Insert_With_Tags 
(Buffer: access Gtk_Text_Buffer_Record;
Iter: in out Gtk.Text_Iter.Gtk_Text_Iter;
Text: UTF8_String;
Tag: Gtk_Text_Tag);

procedure Insert_With_Tags 
(Buffer: access Gtk_Text_Buffer_Record;
Iter: in out Gtk.Text_Iter.Gtk_Text_Iter;
Text: Gtkada.Types.Chars_Ptr;
Tag: Gtk.Text_Tag.Gtk_Text_Tag);
Same as Insert, but specifies the tag to apply to the range.

Get_Buffer 

function Get_Buffer 
(Iter: Gtk_Text_Iter) return Gtk.Text_Buffer.Gtk_Text_Buffer;
Returns the Gtk.Text_Buffer.Gtk_Text_Buffer this iterator is associated with.

Get_Buffer 

function Get_Buffer 
(Mark: Gtk_Text_Mark) return Gtk.Text_Buffer.Gtk_Text_Buffer;

Create_Tag 

function Create_Tag 
(Buffer: access Gtk_Text_Buffer_Record;
Tag_Name: String := "") return Gtk.Text_Tag.Gtk_Text_Tag;
Creates a tag and adds it to the tag table for Buffer. Equivalent to calling gtk.text_tag.gtk_new and then adding the tag to the buffer's tag table. The returned tag is owned by the buffer's tag table, so the ref count will be equal to one. If Tag_Name is NULL, the tag is anonymous, otherwise a tag called Tag_Name must not already exist in the tag table for this buffer.

On_Apply_Tag 

procedure On_Apply_Tag 
(Self: not null access Gtk_Text_Buffer_Record;

Call: Cb_GObject_Gtk_Text_Tag_Gtk_Text_Iter_Gtk_Text_Iter_Void;
Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::apply-tag signal is emitted to apply a tag to a range of text in a Gtk.Text_Buffer.Gtk_Text_Buffer. Applying actually occurs in the default handler. Note that if your handler runs before the default handler it must not invalidate the Start and End iters (or has to revalidate them). See also: Gtk.Text_Buffer.Apply_Tag, gtk_text_buffer_insert_with_tags, Gtk.Text_Buffer.Insert_Range. Callback parameters: -- "tag": the applied tag -- "start": the start of the range the tag is applied to -- "end": the end of the range the tag is applied to

Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::delete-range signal is emitted to delete a range from a Gtk.Text_Buffer.Gtk_Text_Buffer. Note that if your handler runs before the default handler it must not invalidate the Start and End iters (or has to revalidate them). The default signal handler revalidates the Start and End iters to both point point to the location where text was deleted. Handlers which run after the default handler (see g_signal_connect_after) do not have access to the deleted text. See also: Gtk.Text_Buffer.Delete. Callback parameters: -- "start": the start of the range to be deleted -- "end": the end of the range to be deleted

After: Boolean := False);
The ::insert-child-anchor signal is emitted to insert a Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor in a Gtk.Text_Buffer.Gtk_Text_Buffer. Insertion actually occurs in the default handler. Note that if your handler runs before the default handler it must not invalidate the Location iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted Anchor. See also: Gtk.Text_Buffer.Insert_Child_Anchor. Callback parameters: -- "location": position to insert Anchor in Textbuffer -- "anchor": the Gtk.Text_Child_Anchor.Gtk_Text_Child_Anchor to be -- inserted

Note that if your handler runs before the default handler it must not invalidate the Location iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted Pixbuf. See also: Gtk.Text_Buffer.Insert_Pixbuf. Callback parameters: -- "location": position to insert Pixbuf in Textbuffer -- "pixbuf": the Gdk.Pixbuf.Gdk_Pixbuf to be inserted

On_Insert_Text

Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::insert-text signal is emitted to insert text in a Gtk.Text_Buffer.Gtk_Text_Buffer. Insertion actually occurs in the default handler. Note that if your handler runs before the default handler it must not invalidate the Location iter (or has to revalidate it). The default signal handler revalidates it to point to the end of the inserted text. See also: Gtk.Text_Buffer.Insert, Gtk.Text_Buffer.Insert_Range.

Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::mark-set signal is emitted as notification after a Gtk.Text_Mark.Gtk_Text_Mark is set. See also: Gtk.Text_Buffer.Create_Mark, Gtk.Text_Buffer.Move_Mark. Callback parameters: -- "location": The location of Mark in Textbuffer -- "mark": The mark that is set

On_Modified_Changed

(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_Gtk_Text_Buffer_Void;
After: Boolean := False);

On_Modified_Changed 

procedure On_Modified_Changed 
(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_GObject_Void;
Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::modified-changed signal is emitted when the modified bit of a Gtk.Text_Buffer.Gtk_Text_Buffer flips. See also: Gtk.Text_Buffer.Set_Modified.

On_Paste_Done 

procedure On_Paste_Done 
(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_Gtk_Text_Buffer_Gtk_Clipboard_Void;
After: Boolean := False);

On_Paste_Done 

procedure On_Paste_Done 
(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_GObject_Gtk_Clipboard_Void;
Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The paste-done signal is emitted after paste operation has been completed. This is useful to properly scroll the view to the end of the pasted text. See Gtk.Text_Buffer.Paste_Clipboard for more details.

On_Remove_Tag 

procedure On_Remove_Tag 
(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_Gtk_Text_Buffer_Gtk_Text_Tag_Gtk_Text_Iter_Gtk_Text_Iter_Void;
After: Boolean := False);

On_Remove_Tag 

procedure On_Remove_Tag 
(Self: not null access Gtk_Text_Buffer_Record;
Call: Cb_GObject_Gtk_Text_Tag_Gtk_Text_Iter_Gtk_Text_Iter_Void;
Slot: not null access Glib.Object.GObject_Record'Class;
After: Boolean := False);
The ::remove-tag signal is emitted to remove all occurrences of Tag from a range of text in a Gtk.Text_Buffer.Gtk_Text_Buffer. Removal actually occurs in the default handler. Note that if your handler runs before the default handler it must not invalidate the Start and End iters (or has to revalidate them). See also: Gtk.Text_Buffer.Remove_Tag. Callback parameters: -- "tag": the tag to be removed -- "start": the start of the range the tag is removed from -- "end": the end of the range the tag is removed from
