tmplTreeDragSourceT()

Functions

bool dragDataDelete(gtk.tree_path.TreePath path)

Asks the #GtkTreeDragSource to delete the row at path, because it was moved somewhere else via drag-and-drop. Returns false 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!

Parameters

path row that was being dragged

Returns

true if the row was successfully deleted

bool dragDataGet(gtk.tree_path.TreePath path, gtk.selection_data.SelectionData selectionData)

Asks the #GtkTreeDragSource 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`	row that was dragged
`selectionData`	a #GtkSelectionData to fill with data from the dragged row

Returns

true if data of the required type was provided

bool rowDraggable(gtk.tree_path.TreePath path)

Asks the #GtkTreeDragSource 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.

Parameters

path row on which user is initiating a drag

Returns

true if the row can be dragged
