Emmanuele Bassi	e7b2c530c5	Propagate rooting and unrooting widgets to layout managers ... Layout managers may need to get access to data attached to the root of a scene graph.	2019-06-30 23:42:44 +01:00
Emmanuele Bassi	3389ddf6fc	Do not connect to a non-existing signal ... The GtkWidget::parent-set signal was removed in ff6cd8f7. Instead of removing GtkLayoutChild instances associated to a widget using notifications when the widget's parent changes, we can have gtk_widget_unparent() call a method on GtkLayoutManager to remove any eventual GtkLayoutChild instances associated to the widget.	2019-03-26 17:37:49 +00:00
Emmanuele Bassi	24754c3259	Add GtkLayoutManager ... A base abstract class for layout manager delegate objects. Layout managers are associated to a single widget, like event controllers, and are responsible for measuring and allocating the children of the widget they are bound to.	2019-03-26 00:11:27 +00:00
