Gtk.Widget.prototype.get_pointer

function get_pointer():void {
    // Gjs wrapper for gtk_widget_get_pointer()
}

Obtains the location of the mouse pointer in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as widget->window coordinates for widgets that are not #GTK_NO_WINDOW widgets, and are relative to widget->allocation.x, widget->allocation.y for widgets that are #GTK_NO_WINDOW widgets.
