Detailed Description

Interface for Drag-and-Drop destinations in Gtk::TreeView.

Deprecated:

4.10: List views use widgets to display their contents. You can use Gtk::DropTarget to implement a drop destination.

Member Function Documentation

add_interface()

static void Gtk::TreeDragDest::add_interface ( GType  gtype_implementer )

static

drag_data_received()

bool Gtk::TreeDragDest::drag_data_received	(	const TreeModel::Path &	dest,
		const Glib::ValueBase &	value
	)

Asks the Gtk::TreeDragDest to insert a row before the path dest, deriving the contents of the row from value.

If dest is outside the tree so that inserting before it is impossible, false will be returned. Also, false may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!

Deprecated: 4.10: Use list models instead

Parameters

dest	Row to drop in front of.
value	Data to drop.

Returns

Whether a new row was created before position dest.

drag_data_received_vfunc()

virtual bool Gtk::TreeDragDest::drag_data_received_vfunc ( const TreeModel::Path &  dest, const Glib::ValueBase &  value  )

get_type()

gobj() [1/2]

GtkTreeDragDest * Gtk::TreeDragDest::gobj ( )

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkTreeDragDest * Gtk::TreeDragDest::gobj ( ) const

inline

Provides access to the underlying C GObject.

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

noexcept

row_drop_possible()

bool Gtk::TreeDragDest::row_drop_possible	(	const TreeModel::Path &	dest_path,
		const Glib::ValueBase &	value
	)		const

Determines whether a drop is possible before the given dest_path, at the same depth as dest_path.

i.e., can we drop the data in value at that location. dest_path does not have to exist; the return value will almost certainly be false if the parent of dest_path doesn’t exist, though.

Deprecated: 4.10: Use list models instead

Parameters

dest_path	Destination row.
value	The data being dropped.

Returns

true if a drop is possible before dest_path.

row_drop_possible_vfunc()

virtual bool Gtk::TreeDragDest::row_drop_possible_vfunc ( const TreeModel::Path &  dest, const Glib::ValueBase &  value  ) const

Friends And Related Function Documentation

wrap()

Glib::RefPtr< Gtk::TreeDragDest > wrap ( GtkTreeDragDest *  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.
