[PyQt] Custom Widget

[Fernando Cosso]

In the end I was able to integrate the widget to Qt Designer

I added some more stuff to the widget class and I remove the
reimplementation of text() and setText(). I wanted a rich text button
without the other text property.

I could not hide the text property to Qt Designer though

I have attached what I have now

Best Regards
