Member Function Documentation

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

Parameters
destRow to drop in front of.
valueData to drop.
Returns
Whether a new row was created before position dest.
virtual bool Gtk::TreeDragDest::drag_data_received_vfunc ( const TreeModel::Path dest,
const Glib::ValueBase value

static GType Gtk::TreeDragDest::get_type ( )

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

Provides access to the underlying C GObject.

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

Provides access to the underlying C GObject.

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

Parameters
dest_pathDestination row.
valueThe data being dropped.
Returns
true if a drop is possible before dest_path.

Friends And Related Function Documentation

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