Bug 324282 - add selected signal to cell renderer combo.

2006-05-28  Kristian Rietveld  <kris@imendio.com>

	Bug 324282 - add selected signal to cell renderer combo.

	* gtk/gtkcellrenderercombo.c (gtk_cell_renderer_combo_class_init),
	(gtk_cell_renderer_combo_changed),
	(gtk_cell_renderer_combo_start_editing): add a new "changed" signal
	that will be emitted as soon as the combo box emitted changed and has
	an active iterator.  (Modified patch based on work by James
	Pelletier).

	* gtk/gtkmarshalers.list: add marshaler.

* @new_iter: the new iter selected in the combo box
* (relative to the combo box model)
*
* This signal is emitted each time after the user selected an item in
* the combo box, either by using the mouse or the arrow keys. Contrary
* to GtkComboBox, GtkCellRendererCombo::changed is not emitted for
* changes made to a selected item in the entry. The argument @new_iter
* corresponds to the newly selected item in the combo box and it is relative
* to the GtkTreeModel set via the model property on GtkCellRendererCombo.
*
* Note that as soon as you change the model displayed in the tree view,
* the tree view will immediately cease the editing operating. This
* means that you most probably want to refrain from changing the model
* until the combo cell renderer emits the edited or editing_canceled signal.
*
* Since: 2.14
