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. Returns Falseif 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 dragged
- selection_data (Gtk.SelectionData) – a Gtk.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!
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. Returns Falseif 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 dragged
- selection_data (Gtk.SelectionData) – a Gtk.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.
