gtk.TreeDragSource
gtk.TreeDragSource — an interface that manages the source data transfer for a
gtk.TreeView
drag and drop operation
Methods
gtk.TreeDragSource.row_draggable
| path : | the row from which the user is initiating a
drag | 
| Returns : | TRUE if the row can be
dragged | 
The row_draggable() method asks the
gtk.TreeDragSource 
if the row specified by path can be used as the
source of a DND operation. If the gtk.TreeDragSource 
doesn't implement this interface, the row is assumed draggable.
gtk.TreeDragSource.drag_data_delete
|     def drag_data_delete(path)
 | 
| path : | the row that was being
dragged | 
| Returns : | TRUE if the row was
successfully deleted | 
The drag_data_delete() method asks the
gtk.TreeDragSource 
to delete the row specified by path, because it was
moved somewhere else via drag-and-drop. This method returns
FALSE if the deletion fails because
path no longer exists, or for some other
model-specific reason.
gtk.TreeDragSource.drag_data_get
|     def drag_data_get(path, selection_data)
 | 
| path : | the row that was dragged | 
| selection_data : | a gtk.SelectionData 
to fill with data from the dragged row | 
| Returns : | TRUE if data of the required
type was provided | 
The drag_data_get() method asks the
gtk.TreeDragSource 
to fill in the selection data object specified by
selection_data with a representation of the row
specified by path. The
selection_data target attribute gives the required
type of the data.
