304 Animations are used for some state transitions on specific widgets.
305
306 Only one running animation can exist for a widget at any specific
307 time. Animations can be added through
308 QWindowsVistaStylePrivate::startAnimation(Animation *) and any
309 existing animation on a widget can be retrieved with
310 QWindowsVistaStylePrivate::widgetAnimation(Widget *).
311
312 Once an animation has been started,
313 QWindowsVistaStylePrivate::timerEvent(QTimerEvent *) will
314 continuously call update() on the widget until it is stopped,
315 meaning that drawPrimitive will be called many times until the
316 transition has completed. During this time, the result will be
317 retrieved by the Animation::paint(...) function and not by the style
318 itself.
319
320 To determine if a transition should occur, the style needs to know
321 the previous state of the widget as well as the current one. This is
322 solved by updating dynamic properties on the widget every time the
323 function is called.
324
325 Transitions interrupting existing transitions should always be
326 smooth, so whenever a hover-transition is started on a pulsating
327 button, it uses the current frame of the pulse-animation as the
328 starting image for the hover transition.
