bool Gtk::TreeDragSource::drag_data_delete

(

const TreeModel::Path&

path

)

Asks the Gtk::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.

const TreeModel::Path&

bool Gtk::TreeDragSource::drag_data_get	(	const TreeModel::Path&	path,
		SelectionData&	selection_data
	)

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	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.

const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::ListStore, and Gtk::TreeStore.

bool Gtk::TreeDragSource::row_draggable

(

const TreeModel::Path&

path

)

const

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.

Parameters:

path

Row on which user is initiating a drag.

Returns:

true if the row can be dragged.

Friends And Related Function Documentation

Glib::RefPtr< Gtk::TreeDragSource > wrap	(	GtkTreeDragSource *	object,
		bool	take_copy = false
	)			[related]

A Glib::wrap() method for this object.

Parameters:

	object	The C instance.
	take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:

A C++ instance that wraps this C instance.
