Design: When compositing is turned on, XComposite extension is used to redirect drawing of windows to pixmaps and XDamage extension is used to get informed about damage (changes) to window contents. This code is mostly in composite.cpp . Compositor::performCompositing() starts one painting pass. Painting is done by painting the screen, which in turn paints every window. Painting can be affected using effects, which are chained. E.g. painting a screen means that actually paintScreen() of the first effect is called, which possibly does modifications and calls next effect's paintScreen() and so on, until Scene::finalPaintScreen() is called. There are 3 phases of every paint (not necessarily done together): The pre-paint phase, the paint phase and the post-paint phase. The pre-paint phase is used to find out about how the painting will be actually done (i.e. what the effects will do). For example when only a part of the screen needs to be updated and no effect will do any transformation it is possible to use an optimized paint function. How the painting will be done is controlled by the mask argument, see PAINT_WINDOW_* and PAINT_SCREEN_* flags in scene.h . For example an effect that decides to paint a normal windows as translucent will need to modify the mask in its prePaintWindow() to include the PAINT_WINDOW_TRANSLUCENT flag. The paintWindow() function will then get the mask with this flag turned on and will also paint using transparency. The paint pass does the actual painting, based on the information collected using the pre-paint pass. After running through the effects' paintScreen() either paintGenericScreen() or optimized paintSimpleScreen() are called. Those call paintWindow() on windows (not necessarily all), possibly using clipping to optimize performance and calling paintWindow() first with only PAINT_WINDOW_OPAQUE to paint the opaque parts and then later with PAINT_WINDOW_TRANSLUCENT to paint the transparent parts. Function paintWindow() again goes through effects' paintWindow() until finalPaintWindow() is called, which calls the window's performPaint() to do the actual painting. The post-paint can be used for cleanups and is also used for scheduling repaints during the next painting pass for animations. Effects wanting to repaint certain parts can manually damage them during post-paint and repaint of these parts will be done during the next paint pass. */ #include "scene.h" #include #include #include "x11client.h" #include "deleted.h" #include "effects.h" #include "overlaywindow.h" #include "screens.h" #include "shadow.h" +#include "subsurfacemonitor.h" #include "wayland_server.h" #include "thumbnailitem.h" #include #include #include namespace KWin { //**************************************** // Scene //**************************************** Scene::Scene(QObject *parent) : QObject(parent) { last_time.invalidate(); // Initialize the timer } Scene::~Scene() { Q_ASSERT(m_windows.isEmpty()); } // returns mask and possibly modified region void Scene::paintScreen(int* mask, const QRegion &damage, const QRegion &repaint, QRegion *updateRegion, QRegion *validRegion, const QMatrix4x4 &projection, const QRect &outputGeometry, const qreal screenScale) { const QSize &screenSize = screens()->size(); const QRegion displayRegion(0, 0, screenSize.width(), screenSize.height()); *mask = (damage == displayRegion) ? 0 : PAINT_SCREEN_REGION; updateTimeDiff(); // preparation step static_cast(effects)->startPaint(); QRegion region = damage; ScreenPrePaintData pdata; pdata.mask = *mask; pdata.paint = region; effects->prePaintScreen(pdata, time_diff); *mask = pdata.mask; region = pdata.paint; if (*mask & (PAINT_SCREEN_TRANSFORMED | PAINT_SCREEN_WITH_TRANSFORMED_WINDOWS)) { // Region painting is not possible with transformations, // because screen damage doesn't match transformed positions. *mask &= ~PAINT_SCREEN_REGION; region = infiniteRegion(); } else if (*mask & PAINT_SCREEN_REGION) { // make sure not to go outside visible screen region &= displayRegion; } else { // whole screen, not transformed, force region to be full region = displayRegion; } painted_region = region; repaint_region = repaint; if (*mask & PAINT_SCREEN_BACKGROUND_FIRST) { paintBackground(region); } ScreenPaintData data(projection, outputGeometry, screenScale); effects->paintScreen(*mask, region, data); foreach (Window *w, stacking_order) { effects->postPaintWindow(effectWindow(w)); } effects->postPaintScreen(); // make sure not to go outside of the screen area *updateRegion = damaged_region; *validRegion = (region | painted_region) & displayRegion; repaint_region = QRegion(); damaged_region = QRegion(); // make sure all clipping is restored Q_ASSERT(!PaintClipper::clip()); } // Compute time since the last painting pass. void Scene::updateTimeDiff() { if (!last_time.isValid()) { // Painting has been idle (optimized out) for some time, // which means time_diff would be huge and would break animations. // Simply set it to one (zero would mean no change at all and could // cause problems). time_diff = 1; last_time.start(); } else time_diff = last_time.restart(); if (time_diff < 0) // check time rollback time_diff = 1; } // Painting pass is optimized away. void Scene::idle() { // Don't break time since last paint for the next pass. last_time.invalidate(); } // the function that'll be eventually called by paintScreen() above void Scene::finalPaintScreen(int mask, const QRegion ®ion, ScreenPaintData& data) { if (mask & (PAINT_SCREEN_TRANSFORMED | PAINT_SCREEN_WITH_TRANSFORMED_WINDOWS)) paintGenericScreen(mask, data); else paintSimpleScreen(mask, region); } // The generic painting code that can handle even transformations. // It simply paints bottom-to-top. void Scene::paintGenericScreen(int orig_mask, const ScreenPaintData &) { if (!(orig_mask & PAINT_SCREEN_BACKGROUND_FIRST)) { paintBackground(infiniteRegion()); } QVector phase2; phase2.reserve(stacking_order.size()); foreach (Window * w, stacking_order) { // bottom to top Toplevel* topw = w->window(); // Let the scene window update the window pixmap tree. w->preprocess(); // Reset the repaint_region. // This has to be done here because many effects schedule a repaint for // the next frame within Effects::prePaintWindow. topw->resetRepaints(); WindowPrePaintData data; data.mask = orig_mask | (w->isOpaque() ?
