[Qt-interest] How to draw a line on the mainwindow

[Alexandre Beraud]

Hi,

I don't know exactly why theQt::WA_TransparentForMouseEvents attribute 
is not documented and maybe not officialy supported. Anyway it's the 
only way to do it as far as I know. I would add to your tutorial that 
the widget should be raised() every time there is a risk that another 
widget is added over it.

Best regards,

Alex
