示例1: destroyRenderer
bool Object::destroyRenderer(qlib::uid_t uid)
{
// get renderer ptr/check consistency
rendtab_t::iterator i = m_rendtab.find(uid);
if (i==m_rendtab.end())
return false;
RendererPtr pRend = i->second;
ScenePtr pScene = getScene();
if (pScene.isnull() || pRend.isnull()) {
LOG_DPRINTLN("Object::destroyRenderer> fatal error pScene or pRend is NULL!");
return false;
}
// detach renderer from the view-related resources (DL, VBO, etc)
pRend->unloading();
// Detach the parent scene from the renderer event source
pRend->removeListener(pScene.get());
// Fire the SCE_REND_REMOVING Event, before removing the renderer
{
MB_DPRINTLN("Object> Firing SCE_REND_REMOVING event...");
SceneEvent ev;
ev.setType(SceneEvent::SCE_REND_REMOVING);
ev.setSource(getSceneID());
ev.setTarget(pRend->getUID());
pScene->fireSceneEvent(ev);
}
// remove the rend from the scene's cache list
pScene->removeRendCache(pRend);
// 2012/9/30
// Detach the rend from obj HERE is very important!!
// (This call remove the rend from object's event listener list.
// Otherwise, deleted ptr will remain in the listener list, and thus cause crash!!)
qlib::uid_t objid = pRend->detachObj();
// MB_ASSERT(objid==this->m_uid);
// 2012/9/30
// Setting scene ID to null will cause removing pRend from the scene's listener list
// (Without this, deleted ptr will remain in scene's listener list, after clearing the UNDO data!!)
pRend->setSceneID(qlib::invalid_uid);
// Remove from the renderer table
m_rendtab.erase(i);
// Record undo/redo info
UndoManager *pUM = pScene->getUndoMgr();
if (pUM->isOK()) {
ObjLoadEditInfo *pPEI = MB_NEW ObjLoadEditInfo;
pPEI->setupRendDestroy(getUID(), pRend);
pUM->addEditInfo(pPEI);
}
return true;
