Window.show
void show()Like [gdk.window.Window.showUnraised], but also raises the window to the top of the window stack (moves the window to the front of the Z-order).
This function maps a window so it’s visible onscreen. Its opposite is [gdk.window.Window.hide].
When implementing a #GtkWidget, you should call this function on the widget's #GdkWindow as part of the “map” method.
