PyQt5 Alternative to setHandlesChildEvents

Jimbo

Hello,

I have been porting a PyQt4 application to use PyQt5. Everything seems to work fine apart from one thing: setHandlesChildEvents is now obsolete with QGraphicsItemGroup meaning I can no longer pick up on click events on my items within a group.

What is the alternative approach with PyQt5? I have tried replacing it with self.MyGroup.setFiltersChildEvents(False) but this has no effect.

Thanks for any guidance,

Hi,

That's likely a question you should rather ask the PyQt folks. They have a mailing list.

Ok, thank you. I have subscribed to their mailing list and will post my question there.

I believe my question also relates to C++ Qt as well though as I found out about the obsolescence from the documentation pages (http://doc.qt.io/qt-4.8/qgraphicsitem-obsolete.html). So if anyone knows the answer for C++ let me know.

Thanks,

Jimbo

I haven't worked with graphics items but...

They seem relevant, perhaps they will be useful. It does seem that the issue and solution are not related to Python specifically.

Thanks Kyle.

In the end I solved it by subclassing my qgraphicsitemgroup and adding a sceneEventFilter.

This appears to be the approach the C++ people take
