[Gambas-user] Button Transparency

[KKing]

just to elaborate I'm trying create the button on top of an ImageView ...
I have a scanned document in the ImageView
When I set the button background to transparent (without picture on 
button) I get black I want to see the scanned document in the ImageView.
It doesn't have to be a button, so will look at other controls I could 
draw on it and hopefully see through it and be able to click on it.
