struct Gtk::Widget::MapSignal

Overview

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with Gtk::Widget#visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of Gtk::Widget::#unmap.
