Hi to all,
I have a widget showing an audio waveform. I'm adding a functionality where the user can select part of it and I show the selection with a rubberband. The widget also has a zoom in/out feature and it's resizable.
So when I zoom in a QScrollArea manage the content of such widget activating a scrollbar.
What I would know is how to select in case of the widget is zoomed as for example the startpoint of the selection ( in case of zoom ) can not be in the visible part of the widget.
I hope to get help.
Regards,
Franco
