Modularization of KWin

Removing Scene dependency from Core

Use of Workspace

• scene_open_glx.cpp and scene_opengl_egl.cpp
  • wspace->destroyOverlay();
  • wspace->overlayWindow();
  • wspace->createOverlay();
  • wspace->setupOverlay(buffer);

• only scene_open_glx.cpp
  • QTimer::singleShot(0, Workspace::self(), SLOT(fallbackToXRenderCompositing()));

• scene_xrender.cpp
  • wspace->createOverlay();
  • wspace->setupOverlay(None);
  • wspace->overlayWindow()
  • wspace->destroyOverlay();
  • wspace->setOverlayShape(reg);
  • wspace->showOverlay();
  • wspace->hideOverlay();
  • QTimer::singleShot(0, Workspace::self(), SLOT(finishCompositing()));
  • Workspace::self()->decorationHasAlpha()

Use of Toplevel (in Scene::Window)

• scene.cpp
  • toplevel->shape()
  • toplevel->frameId()
  • toplevel->clientPos()
  • toplevel->clientSize()
  • toplevel->isOnCurrentDesktop()
  • toplevel->isOnCurrentActivity()
  • toplevel->geometry()
  • toplevel->opacity()
  • toplevel->hasAlpha()
  • toplevel->visibleRect().size()

• scene_opengl.cpp
  • toplevel->damage()
  • toplevel->windowPixmap()
  • toplevel->size()
  • toplevel->depth()
  • toplevel->resetDamage
  • toplevel->clientPos()
  • toplevel->clientSize()
  • toplevel->visibleRect()
  • toplevel->hasAlpha()

• scene_xrender.cpp
  • toplevel->damage()
  • toplevel->windowPixmap()
  • toplevel->resetDamage
  • toplevel->rect()
  • toplevel)->decorationRect()
  • toplevel->visibleRect()
  • toplevel->clientPos()
  • toplevel->clientSize()

• scene_open_glx.cpp and scene_opengl_egl.cpp
  • void SceneOpenGL::paint(QRegion damage, ToplevelList toplevels)

Use of Client (in Scene::Window)

• scene.cpp
  • c->mask()
  • c->isShade()
  • c->isShown(true);
  • c->isMinimized()
  • c->clientGroup()
  • c->isHiddenInternal()
  • client->decorationRect()
  • client->layoutDecorationRects()
  • c->effectWindow()

• scene_opengl.cpp
  • client->noBorder()
  • client->decorationPixmapRequiresRepaint();
  • client->ensureDecorationPixmapsPainted();
  • client->layoutDecorationRects()
  • client->leftDecoPixmap();
  • client->topDecoPixmap();
  • client->rightDecoPixmap();
  • client->bottomDecoPixmap();

• scene_xrender.cpp
  • client->decorationRect();
  • client->noBorder()
  • client->ensureDecorationPixmapsPainted();
  • client->leftDecoPixmap();
  • client->topDecoPixmap();
  • client->rightDecoPixmap();
  • client->bottomDecoPixmap();

Use of Deleted (in Scene::Window)

Besides checks, if dynamic_cast< Deleted* >(toplevel) != NULL, Toplevel's sublclass Deleted is used in:

• scene_opengl.cpp
  • deleted->noBorder()
  • deleted->leftDecoPixmap();
  • deleted->topDecoPixmap();
  • deleted->rightDecoPixmap();
  • deleted->bottomDecoPixmap();
  • deleted->layoutDecorationRects();

• scene_xrender.cpp
  • deleted->decorationRect()
  • deleted->noBorder()
  • deleted->leftDecoPixmap();
  • deleted->topDecoPixmap();
  • deleted->rightDecoPixmap();
  • deleted->bottomDecoPixmap();
  • deleted->layoutDecorationRects();
  • deleted->decorationRect()
