Subprograms & Entries

Get_Type

function Get_Type return Glib.GType;

Drag_Data_Received

function Drag_Data_Received 
(Self: Gtk_Tree_Drag_Dest;
Dest: Gtk.Tree_Model.Gtk_Tree_Path;
Selection_Data: Gtk.Selection_Data.Gtk_Selection_Data) return Boolean;
Asks the Gtk.Tree_Drag_Dest.Gtk_Tree_Drag_Dest to insert a row before the path Dest, deriving the contents of the row from Selection_Data. If Dest is outside the tree so that inserting before it is impossible, False will be returned. Also, False may be returned if the new row is not created for some model-specific reason. Should robustly handle a Dest no longer found in the model! "dest": row to drop in front of "selection_data": data to drop

Row_Drop_Possible

function Row_Drop_Possible 
(Self: Gtk_Tree_Drag_Dest;
Dest_Path: Gtk.Tree_Model.Gtk_Tree_Path;
Selection_Data: Gtk.Selection_Data.Gtk_Selection_Data) return Boolean;
Determines whether a drop is possible before the given Dest_Path, at the same depth as Dest_Path. i.e., can we drop the data in Selection_Data at that location. Dest_Path does not have to exist; the return value will almost certainly be False if the parent of Dest_Path doesn't exist, though. "dest_path": destination row "selection_data": the data being dragged
