Hello, I am developing a Qt-based application. The main part of the application if a QGraphicView widget whose scene is populated with thousands (sometimes hundreds of thousands) of QGraphicItems, more precisely a subclass because to overload the "paint" function in order to draw a circle for each item.
The problem is that the application basically freezes when I load a lot of items. Is this normal? Is there a limit on the number of QGraphicItems that you can visualize? Also, if you want QGraphicItems to respond to a certain signal, do you need to connect the signal to an slot for each of the items? As an alternative, I can draw all the dots as a one single QGraphicItems which will solve the problem, I guees, but I would lose the interaction with the dots individually. Any help would be much appreciated. Thanks in advance. //Jose
