Connect dynamically created QGraphicsItem to parent
-
Hi all,
I look for a way to connect QGraphicsItems to its parent by Signal/Slot. I believe I can inherit from QOject, to produce signals.
But my QGraphicsItems are dynamically created.
- The first problem is that I haven't found the method to create any dynamically array of QGraphicsItem derived class,
- and how to connect to its parent please ???
Thanks in advance ;)

Hi and welcome to devnet,
You might be interested by "QGraphicsObject":http://doc.qt.io/qt-5/QGraphicsObject.html
- You have to create them all and add them to your array
- The children should not be responsible of the connection, they should only emit signals so you can change easily what is connected to that signal.
Hope it helps

The post size have a limit. Did you try to paste a big chunk of code ?
Is something like
@QVector<QObject *> myStorage;@
What you have in mind ? -
No it's not, QObject is not copyable
