<a name="GdkFrameClock.description"></a><h2>Description</h2>
|
||||
<p>A <a class="link" href="GdkFrameClock.html" title="Frame clock"><span class="type">GdkFrameClock</span></a> tells the application when to update and repaint a
|
||||
window. This may be synced to the vertical refresh rate of the
|
||||
monitor, for example. Even when the frame clock uses a simple timer
|
||||
rather than a hardware-based vertical sync, the frame clock helps
|
||||
because it ensures everything paints at the same time (reducing the
|
||||
total number of frames). The frame clock can also automatically
|
||||
stop painting when it knows the frames will not be visible, or
|
||||
scale back animation framerates.</p>
|
||||
<p><a class="link" href="GdkFrameClock.html" title="Frame clock"><span class="type">GdkFrameClock</span></a> is designed to be compatible with an OpenGL-based
|
||||
implementation or with mozRequestAnimationFrame in Firefox,
|
||||
for example.</p>
|
||||
<p>A frame clock is idle until someone requests a frame with
|
||||
<a class="link" href="GdkFrameClock.html#gdk-frame-clock-request-phase" title="gdk_frame_clock_request_phase ()"><code class="function">gdk_frame_clock_request_phase()</code></a>. At some later point that makes
|
||||
sense for the synchronization being implemented, the clock will
|
||||
process a frame and emit signals for each phase that has been
|
||||
requested. (See the signals of the <a class="link" href="GdkFrameClock.html" title="Frame clock"><span class="type">GdkFrameClock</span></a> class for
|
||||
documentation of the phases. <a class="link" href="GdkFrameClock.html#GDK-FRAME-CLOCK-PHASE-UPDATE:CAPS"><code class="literal">GDK_FRAME_CLOCK_PHASE_UPDATE</code></a> and the
|
||||
<a class="link" href="GdkFrameClock.html#GdkFrameClock-update" title="The “update” signal"><span class="type">“update”</span></a> signal are most interesting for application
|
||||
writers, and are used to update the animations, using the frame time
|
||||
given by <a class="link" href="GdkFrameClock.html#gdk-frame-clock-get-frame-time" title="gdk_frame_clock_get_frame_time ()"><code class="function">gdk_frame_clock_get_frame_time()</code></a>.</p>
|
||||
<p>The frame time is reported in microseconds and generally in the same
|
||||
timescale as <a href="../glib/glib-Date-and-Time-Functions.html#g-get-monotonic-time"><code class="function">g_get_monotonic_time()</code></a>, however, it is not the same
|
||||
as <a href="../glib/glib-Date-and-Time-Functions.html#g-get-monotonic-time"><code class="function">g_get_monotonic_time()</code></a>. The frame time does not advance during
|
||||
the time a frame is being painted, and outside of a frame, an attempt
|
||||
is made so that all calls to <a class="link" href="GdkFrameClock.html#gdk-frame-clock-get-frame-time" title="gdk_frame_clock_get_frame_time ()"><code class="function">gdk_frame_clock_get_frame_time()</code></a> that
|
||||
are called at a “similar” time get the same value. This means that
|
||||
if different animations are timed by looking at the difference in
|
||||
time between an initial value from <a class="link" href="GdkFrameClock.html#gdk-frame-clock-get-frame-time" title="gdk_frame_clock_get_frame_time ()"><code class="function">gdk_frame_clock_get_frame_time()</code></a>
|
||||
and the value inside the <a class="link" href="GdkFrameClock.html#GdkFrameClock-update" title="The “update” signal"><span class="type">“update”</span></a> signal of the clock,
|
||||
they will stay exactly synchronized.</p>
