Member Function Documentation

static void Gtk::TreeDragSource::add_interface ( GType  gtype_implementer)
static
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
pathRow that was being dragged.
Returns
true if the row was successfully deleted.
virtual bool Gtk::TreeDragSource::drag_data_delete_vfunc ( const TreeModel::Path path)
protectedvirtual
Glib::RefPtr<Gdk::ContentProvider> Gtk::TreeDragSource::drag_data_get ( const TreeModel::Path path) const

Asks the Gtk::TreeDragSource to return a Gdk::ContentProvider representing the row at path.

Should robustly handle a path no longer found in the model!

Parameters
pathRow that was dragged.
Returns
A Gdk::ContentProvider for the given path or nullptr if none exists.

static GType Gtk::TreeDragSource::get_type ( )

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

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

Provides access to the underlying C GObject.

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

Provides access to the underlying C GObject.

TreeDragSource& Gtk::TreeDragSource::operator= ( TreeDragSource&&  src)
noexcept
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
pathRow on which user is initiating a drag.
Returns
true if the row can be dragged.

bool  take_copy = false 
)
related

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

Parameters
objectThe C instance.
take_copyFalse 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.
