⚠️ Deprecated ⚠️
This is deprecated since version 4.10.
Use method@Gtk.Widget.set_visible instead
---Flags a widget to be displayed.
Any widget that isn’t shown will not appear on the screen.
Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen.
When a toplevel container is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel container is realized and mapped.
