Class Details¶
- class Gtk.TreeDragSource¶
- Bases
- Structure
- drag_data_delete(path)[source]¶
- Parameters
path (
Gtk.TreePath
) – row that was being dragged- Returns
True
if the row was successfully deleted- Return type
Asks the
Gtk.TreeDragSource
to delete the row at path, because it was moved somewhere else via drag-and-drop. ReturnsFalse
if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!
- drag_data_get(path, selection_data)[source]¶
- Parameters
path (
Gtk.TreePath
) – row that was draggedselection_data (
Gtk.SelectionData
) – aGtk.SelectionData
to fill with data from the dragged row
- Returns
True
if data of the required type was provided- Return type
Asks the
Gtk.TreeDragSource
to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!
- row_draggable(path)[source]¶
- Parameters
path (
Gtk.TreePath
) – row on which user is initiating a drag- Returns
True
if the row can be dragged- Return type
Asks the
Gtk.TreeDragSource
whether a particular row can be used as the source of a DND operation. If the source doesn’t implement this interface, the row is assumed draggable.
- do_drag_data_delete(path) virtual¶
- Parameters
path (
Gtk.TreePath
) – row that was being dragged- Returns
True
if the row was successfully deleted- Return type
Asks the
Gtk.TreeDragSource
to delete the row at path, because it was moved somewhere else via drag-and-drop. ReturnsFalse
if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!
- do_drag_data_get(path, selection_data) virtual¶
- Parameters
path (
Gtk.TreePath
) – row that was draggedselection_data (
Gtk.SelectionData
) – aGtk.SelectionData
to fill with data from the dragged row
- Returns
True
if data of the required type was provided- Return type
Asks the
Gtk.TreeDragSource
to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!
- do_row_draggable(path) virtual¶
- Parameters
path (
Gtk.TreePath
) – row on which user is initiating a drag- Returns
True
if the row can be dragged- Return type
Asks the
Gtk.TreeDragSource
whether a particular row can be used as the source of a DND operation. If the source doesn’t implement this interface, the row is assumed draggable.
