You can use gtk.drag_source.DragSource to implement a drag source
gtk.tree_drag_source_mixin
Module for TreeDragSource interface mixin
Templates 2
tmplTreeDragSourceT()
Interface for Drag-and-Drop destinations in gtk.tree_view.TreeView.
Deprecated
List views use widgets to display their contents.
Functions
bool dragDataDelete(gtk.tree_path.TreePath path)
Asks the gtk.tree_drag_source.TreeDragSource 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
Deprecated
Use list models instead
gdk.content_provider.ContentProvider dragDataGet(gtk.tree_path.TreePath path)
Asks the gtk.tree_drag_source.TreeDragSource to return a gdk.content_provider.ContentProvider representing the row at path. Should robustly handle a path no longer found in the model!
Parameters
path | row that was dragged |
Returns
a gdk.content_provider.ContentProvider for the
given path
Deprecated
Use list models instead
bool rowDraggable(gtk.tree_path.TreePath path)
Asks the gtk.tree_drag_source.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.
Parameters
path | row on which user is initiating a drag |
Returns
true if the row can be dragged
Deprecated
Use list models instead
tmplTreeDragSourceGidBuilderT()
Fluent builder implementation template for gtk.tree_drag_source.TreeDragSource
