gtk_style_context_get_style_property(style, "prop-name", &value);
//or
gtk_style_context_get_property(style, "prop-name", &value);

Is there any way to disable the editing-cancelled event on cellrenderertext.
Background
When I have a liststore contained within a treestore I want the value to be
be saved if I click on a button not contained within the treeview, so that
it does not just dissapear
Focus events dont seem to work
