Connect dynamically created QGraphicsItem to parent

neoirto

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 anti-spam of the forum don't let me answer !
[EDIT] : Ok, so tx for your answer : is it possible to create a dynamic storage type of QObject class ? With Qvector perhaps ?

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 ?

I would like to do something like
@QVector<QObject>@
? But it don't seem to be possible ?

No it's not, QObject is not copyable
