qt - Layout problems when switch from QWidget to QGraphicsItem -


i'm switching timeline viewer qwidget qgraphicsitem, because qwidget heavy, got performance issues when there thousand of qwidgets.

i need layout management. found qgraphicsitem light, did't support layout. should use qgraphicswidget, there many useful qgraphicsitem's subclasses, qgraphicswidget doesn't have them. think qgraphicsproxywidget isn't answer because slow when using qwidgets...

so, there way have layout qgraphicsitem? or there better solution?
