Capturing mouse click on QwtScaleWidget

[mmangold]

Hi all,

I'd like to detect a mouse double click on the yLeft scale of my plot. I've searched up and down and haven't found anyone else who has done the same, so I thought I'd come here and ask. I'm familiar with implementing a custom QwtScaleDraw class and have done so, but it's not a widget so it has no mouse click events. I see there is a QwtScaleWidget class, and I have implemented a subclass of that and installed a mouseDoubleClickEvent handler, but I can't seem to figure how to replace the existing QwtScaleWidget attached to the plot. Any idea how I can handle a double click on a scale widget? Am I over thinking this?

Thanks!

See QObject::installEventFilter(). F.e ScalePicker in the event_filter example uses it.
