Gtk_Custom_Sorter_New_User

function Gtk_Custom_Sorter_New_User
  (Sort_Func : Gcompare_Data_Func;
   User_Data : User_Data_Type)
return Gtk_Custom_Sorter

Creates a new GtkSorter that works by calling Sort_Func to compare items. If Sort_Func is null, all items are considered equal.

Parameters

Sort_Func

the GCompareDataFunc to use for sorting

User_Data

Return Value

Gtk_New_User

procedure Gtk_New_User
  (Self      : out Gtk_Custom_Sorter;
   Sort_Func : Gcompare_Data_Func;
   User_Data : User_Data_Type)

Creates a new GtkSorter that works by calling Sort_Func to compare items. If Sort_Func is null, all items are considered equal. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Sort_Func

the GCompareDataFunc to use for sorting

User_Data

Initialize_User

procedure Initialize_User
  (Self      : not null access Gtk_Custom_Sorter_Record'Class;
   Sort_Func : Gcompare_Data_Func;
   User_Data : User_Data_Type)

Creates a new GtkSorter that works by calling Sort_Func to compare items. If Sort_Func is null, all items are considered equal. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

User_Data

Set_Sort_Func_User

procedure Set_Sort_Func_User
  (Self      : not null access Gtk.Custom_Sorter.Gtk_Custom_Sorter_Record'Class;
   Sort_Func : Gcompare_Data_Func;
   User_Data : User_Data_Type)

Sets (or unsets) the function used for sorting items. If Sort_Func is null, all items are considered equal. If the sort func changes its sorting behavior, Gtk.Sorter.Changed needs to be called. If a previous function was set, its User_Destroy will be called now.

Parameters

Self

Sort_Func

function to sort items

User_Data

user data to pass to Match_Func

User_Data_Type

type User_Data_Type (<>) is private;
