PyQt4 pinch-zoom

Fri Jan 27, 2017 7:48 am

Hi, I started with designing an GUI application on Raspberry Pi 3, I am using PyQt4. For plotting graphs on that app I am using pytqgraph. At this point, I am testing the option to zoom/pan those graphs, not by mouse, but by using the multi-touch RPI screen (pinch-zoom). I made research, and tested some event functions that I found on internet,but my touch events are not detected. Can please someone give me instructions.

Thank you.

I have the same problem and can't find any solution.
Can someone let us know if that is possible or not?

Thank you.
