public virtual signal void layout_changed ()
The layout_changed signal is emitted each time a layout manager has been changed.
Every Actor using the
manager instance as a layout manager should
connect a handler to the layout_changed signal and queue a relayout on themselves:
static void layout_changed (ClutterLayoutManager *manager,
self->manager = g_object_ref_sink (manager);
g_signal_connect (self->manager, "layout-changed",
Sub-classes of LayoutManager that implement a layout that can be controlled or changed using parameters should emit the layout_changed signal whenever one of the parameters changes, by using layout_changed.
