示例1: paintWindow
void LogoutEffect::paintWindow(EffectWindow* w, int mask, QRegion region, WindowPaintData& data)
{
if (progress > 0.0) {
if (effects->compositingType() == KWin::OpenGLCompositing) {
// In OpenGL mode we add vignetting and, if supported, a slight blur
if (blurSupported) {
// When using blur we render everything to an FBO and as such don't do the vignetting
// until after we render the FBO to the screen.
if (w == logoutWindow) {
// Window is rendered after the FBO
windowOpacity = data.opacity();
data.setOpacity(0.0); // Cheat, we need the opacity for later but don't want to blur it
} else {
if (logoutWindowPassed || ignoredWindows.contains(w)) {
// Window is rendered after the FBO
windows.append(w);
windowsOpacities[ w ] = data.opacity();
data.setOpacity(0.0);
} else // Window is added to the FBO
data.multiplySaturation((1.0 - progress * 0.2));
}
} else {
// If we are not blurring then we are not rendering to an FBO
if (w == logoutWindow)
// This is the logout window don't alter it but render our vignetting now
renderVignetting();
else if (!logoutWindowPassed && !ignoredWindows.contains(w))
// Window is in the background, desaturate
data.multiplySaturation((1.0 - progress * 0.2));
// All other windows are unaltered
}
}
if (effects->compositingType() == KWin::XRenderCompositing) {
// Since we can't do vignetting in XRender just do a stronger desaturation and darken
if (w != logoutWindow && !logoutWindowPassed && !ignoredWindows.contains(w)) {
data.multiplySaturation((1.0 - progress * 0.8));
data.multiplyBrightness((1.0 - progress * 0.3));
}
}
if (w == logoutWindow ||
ignoredWindows.contains(w)) // HACK: All windows past the first ignored one should not be
// blurred as it affects the stacking order.
// All following windows are on top of the logout window and should not be altered either
logoutWindowPassed = true;
}
effects->paintWindow(w, mask, region, data);
