Gtk.Widget.prototype.get_frame_clock

function get_frame_clock():Gdk.FrameClock {
    // Gjs wrapper for gtk_widget_get_frame_clock()
}

Obtains the frame clock for a widget. The frame clock is a global "ticker" that can be used to drive animations and repaints. The most common reason to get the frame clock is to call Gdk.get_frame_time, in order to get a time to use for animating. For example you might record the start of the animation with an initial value from Gdk.get_frame_time, and then update the animation by calling Gdk.get_frame_time again during each repaint.

Gdk.request_phase will result in a new frame on the clock, but won't necessarily repaint any widgets. To repaint a widget, you have to use Gtk.queue_draw which invalidates the widget (thus scheduling it to receive a draw on the next frame). Gtk.queue_draw will also end up requesting a frame on the appropriate frame clock.

A widget's frame clock will not change while the widget is mapped. Reparenting a widget (which implies a temporary unmap) can change the widget's frame clock.

Unrealized widgets do not have a frame clock.
