Gtk.Widget.prototype.get_visible

function get_visible():Boolean {
    // Gjs wrapper for gtk_widget_get_visible()
}

Determines whether the widget is visible. If you want to take into account whether the widget's parent is also marked as visible, use Gtk.is_visible instead.

This function does not check if the widget is obscured in any way.

See Gtk.set_visible.
