[PyQt] button delegate in a tableview

[Cristobal Infante]

Hi Eric,

Thanks for the tip, I've managed to get my button inside my tableview.

There is only one thing that bothers me, not sure if it is a limitation or
something I can fix.

To be able to press a button, I need to "activate" the containing cell with
a click.
Once the cell is active I can press the button. This could become confusing
for your average user.

Is this fixable?

Best,
Cris
