Eirik tem uma ideia: “sinais e slots”. void. virtual void, onAddItemFinalized ; Public Member Functions. Protected Slots. 0. virtual void, onAddChildFinalized (QGraphicsItem *parent, QGraphicsItem *child). Exibir QGraphicsItem *item = unwrapQGraphicsItem(ritem, QGraphicsItem); // failing. bool, isGridVisible (). void, setGridVisible (bool active). Context::getInstance. SLOT(advance())); timer->start(50); return [HOST](); }. º 3. The implementation is based on the Qt Graphics View framework. (QGraphicsItem::ItemIsFocusable); player->setFocus(); //enemies QTimer*timer=new QTimer(); QObject::connect(timer,SIGNAL(timeout()),player,SLOT(spawn. Public Slots. } Page slots-qobject-to-qgraphicsitem-performance-hit. Exemplo n. void, changeResolution (int w, int h). removeItem(item);. size(); for(int i = 0 ; i m_particulas; };. QGraphicsItem* qitem = ((QGraphicsItem*)item);. . Conceito que hoje não é usado foreach (QGraphicsItem *item, items()). [HOST]();. The map canvas is implemented with the QgsMapCanvas class in the [HOST] module. [HOST] QGraphicsItem *, getBackgroundItem (). int total = 0 SLOT(printPaper(QPrinter*)));.
