gtk.TreeDragSource
gtk.TreeDragSource — an interface that manages the source data transfer for a
gtk.TreeView
drag and drop operation
Synopsis
class gtk.TreeDragSource(gobject.GInterface): |
Description
A gtk.TreeDragSource is an interface that provides for the management of the source data for a gtk.TreeView drag and drop operation.
Methods
gtk.TreeDragSource.row_draggable
def 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)
| 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)
| the row that was dragged |
| 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.
