Subprograms & Entries

From_Object_Free 

function From_Object_Free 
(B: access Pango_Attribute) return Pango_Attribute;

From_Object 

function From_Object 
(Object: System.Address) return Pango_Attr_List;

From_Object_Free 

function From_Object_Free 
(B: access Pango_Attr_List'Class) return Pango_Attr_List;

Gdk_New 

procedure Gdk_New 
(Self: out Pango_Attr_List);
Create a new empty attribute list with a reference count of one.

Pango_Attr_List_New 

function Pango_Attr_List_New return Pango_Attr_List;
Create a new empty attribute list with a reference count of one.

Get_Type 

function Get_Type return Glib.GType;

Copy 

function Copy 
(Self: Pango_Attribute) return Pango_Attribute;

Copy 

function Copy 
(Self: Pango_Attr_List) return Pango_Attr_List;
Copy List and return an identical new list.

Destroy 

procedure Destroy 
(Self: Pango_Attribute);

Equal 

function Equal 
(Self: Pango_Attribute;
Attr2: Pango_Attribute) return Boolean;
Compare two attributes for equality. This compares only the actual value of the two attributes and not the ranges that the attributes apply to. "attr2": another Pango.Attributes.Pango_Attribute

Change 

procedure Change 
(Self: Pango_Attr_List;
Attr: Pango_Attribute);
Insert the given attribute into the Pango.Attributes.Pango_Attr_List. It will replace any attributes of the same type on that segment and be merged with any adjoining attributes that are identical. This function is slower than Pango.Attributes.Insert for creating a attribute list in order (potentially much slower for large lists). However, Pango.Attributes.Insert is not suitable for continually changing a set of attributes since it never removes or combines existing attributes. "attr": the attribute to insert. Ownership of this value is assumed by the list.

Filter 

function Filter 
(Self: Pango_Attr_List;
Func: Pango_Attr_Filter_Func) return Pango_Attr_List;
Given a Pango.Attributes.Pango_Attr_List and callback function, removes any elements of List for which Func returns True and inserts them into a new list. Since: gtk+ 1.2 "func": callback function; returns True if an attribute should be filtered out.

Insert 

procedure Insert 
(Self: Pango_Attr_List;
Attr: Pango_Attribute);
Insert the given attribute into the Pango.Attributes.Pango_Attr_List. It will be inserted after all other attributes with a matching Start_Index. "attr": the attribute to insert. Ownership of this value is assumed by the list.

Insert_Before 

procedure Insert_Before 
(Self: Pango_Attr_List;
Attr: Pango_Attribute);
Insert the given attribute into the Pango.Attributes.Pango_Attr_List. It will be inserted before all other attributes with a matching Start_Index. "attr": the attribute to insert. Ownership of this value is assumed by the list.

Ref 

function Ref 
(Self: Pango_Attr_List) return Pango_Attr_List;
Increase the reference count of the given attribute list by one. Since: gtk+ 1.10

Splice 

procedure Splice 
(Self: Pango_Attr_List;
Other: Pango_Attr_List;
Pos: Gint;
Len: Gint);
This function opens up a hole in List, fills it in with attributes from the left, and then merges Other on top of the hole. This operation is equivalent to stretching every attribute that applies at position Pos in List by an amount Len, and then calling Pango.Attributes.Change with a copy of each attribute in Other in sequence (offset in position by Pos). This operation proves useful for, for instance, inserting a pre-edit string in the middle of an edit buffer. "other": another Pango.Attributes.Pango_Attr_List "pos": the position in List at which to insert Other "len": the length of the spliced segment. (Note that this must be specified since the attributes in Other may only be present at some subsection of this range)

Unref 

procedure Unref 
(Self: Pango_Attr_List);
Decrease the reference count of the given attribute list by one. If the result is zero, free the attribute list and the attributes it contains.

Attr_Underline_New 

function Attr_Underline_New 
(Underline: Pango.Enums.Underline) return Pango_Attribute;

Attr_Background_New 

function Attr_Background_New 
(Red: Guint16;
Green: Guint16;
Blue: Guint16) return Pango_Attribute;

Attr_Foreground_New 

function Attr_Foreground_New 
(Red: Guint16;
Green: Guint16;
Blue: Guint16) return Pango_Attribute;

Attr_Family_New 

function Attr_Family_New 
(Family: UTF8_String) return Pango_Attribute;
Create a new font family attribute. "family": the family or comma separated list of families

Attr_Strikethrough_New 

function Attr_Strikethrough_New 
(Strikethrough: Boolean) return Pango_Attribute;
Create a new strike-through attribute. "strikethrough": True if the text should be struck-through.

(Rise: Gint) return Pango_Attribute;
