Gtk.Tree_Drag_Dest

Description

Interface for Drag-and-Drop destinations in GtkTreeView.

<group>Trees and Lists</group>

"+"

function "+" (W : Gtk_Tree_Drag_Dest) return Gtk_Tree_Drag_Dest

Parameters

W

Return Value

Drag_Data_Received

function Drag_Data_Received
   (Self  : Gtk_Tree_Drag_Dest;
    Dest  : Gtk.Tree_Model.Gtk_Tree_Path;
    Value : in out Glib.Values.GValue) return Boolean

Asks the GtkTreeDragDest to insert a row before the path Dest, deriving the contents of the row from Value. 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! Deprecated since 4.10, 1

Parameters

Self

Dest

row to drop in front of

Value

data to drop

Return Value

whether a new row was created before position Dest

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_Tree_Drag_Dest

type Gtk_Tree_Drag_Dest is new Glib.Types.GType_Interface;

Null_Gtk_Tree_Drag_Dest

Null_Gtk_Tree_Drag_Dest : constant Gtk_Tree_Drag_Dest;

Row_Drop_Possible

function Row_Drop_Possible
   (Self      : Gtk_Tree_Drag_Dest;
    Dest_Path : Gtk.Tree_Model.Gtk_Tree_Path;
    Value     : in out Glib.Values.GValue) 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 Value 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. Deprecated since 4.10, 1

Parameters

Self

Dest_Path

destination row

Value

the data being dropped

Return Value

True if a drop is possible before Dest_Path

Set_Drag_Data_Received

procedure Set_Drag_Data_Received
  (Self    : Tree_Drag_Dest_Interface_Descr;
   Handler : Virtual_Drag_Data_Received)

Parameters

Self

Handler

Set_Row_Drop_Possible

procedure Set_Row_Drop_Possible
  (Self    : Tree_Drag_Dest_Interface_Descr;
   Handler : Virtual_Row_Drop_Possible)

See Glib.Object.Add_Interface

Parameters

Self

Handler

Tree_Drag_Dest_Interface_Descr

subtype Tree_Drag_Dest_Interface_Descr is Glib.Object.Interface_Description;

Virtual_Drag_Data_Received

type Virtual_Drag_Data_Received is access function
  (Self  : Gtk_Tree_Drag_Dest;
   Dest  : System.Address;
   Value : in out Glib.Values.GValue) return Glib.Gboolean;

Asks the GtkTreeDragDest to insert a row before the path Dest, deriving the contents of the row from Value. 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! Deprecated since 4.10, 1

Parameters

Self

Dest

row to drop in front of

Value

data to drop

Return Value

whether a new row was created before position Dest

Virtual_Row_Drop_Possible

type Virtual_Row_Drop_Possible is access function
  (Self      : Gtk_Tree_Drag_Dest;
   Dest_Path : System.Address;
   Value     : in out Glib.Values.GValue) return Glib.Gboolean;

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 Value 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. Deprecated since 4.10, 1

Parameters

Self

Dest_Path

destination row

Value

the data being dropped

Return Value

True if a drop is possible before Dest_Path
