getFrameClock

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 method@Gdk.FrameClock.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 method@Gdk.FrameClock.get_frame_time, and then update the animation by calling method@Gdk.FrameClock.get_frame_time again during each repaint.

method@Gdk.FrameClock.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 method@Gtk.Widget.queue_draw which invalidates the widget (thus scheduling it to receive a draw on the next frame). gtk_widget_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.
