drag_data_delete()

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.

drag_data_delete_vfunc()

virtual bool Gtk::TreeDragSource::drag_data_delete_vfunc ( const TreeModel::Path &  path )

protectedvirtual

drag_data_get()

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.

drag_data_get_vfunc()

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

protectedvirtual

get_type()

static GType Gtk::TreeDragSource::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GtkTreeDragSource * Gtk::TreeDragSource::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkTreeDragSource * Gtk::TreeDragSource::gobj ( ) const

inline

Provides access to the underlying C GObject.

operator=()

TreeDragSource & Gtk::TreeDragSource::operator= ( TreeDragSource &&  src )

noexcept

row_draggable()

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.

row_draggable_vfunc()

virtual bool Gtk::TreeDragSource::row_draggable_vfunc ( const TreeModel::Path &  path ) const

wrap()

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.
