The implementation is based on the Qt Graphics View framework. [HOST]();.

Conceito que hoje não é usado foreach (QGraphicsItem *item, items()). SLOT(advance())); timer->start(50); return [HOST](); }. Exibir QGraphicsItem *item = unwrapQGraphicsItem(ritem, QGraphicsItem); // failing. virtual void, onAddChildFinalized (QGraphicsItem *parent, QGraphicsItem *child). . Eirik tem uma ideia: “sinais e slots”. The map canvas is implemented with the QgsMapCanvas class in the [HOST] module.
