[Qt-interest] Creating dialogs with "round corners"

[Markus Franke]

Dear QT Developers/Users,

in my embedded QT application I would like to use dialogs (i.e. owning  
layouts, buttons, ...). Furthermore, these dialogs should have "round  
corners" (sorry for the term). So far I am using QLabels for the  
dialogs and stylesheets to obtain the "round corners".

First of all: Is this the right way to do in Qt?

I know that I should maybe use QDialog for my dialog windows but so  
far I didn't find a way to style a QDialog with "round corners".

Furthermore, now I have problems when I want to apply a layout to my  
dialog windows (which are derived from QLabel). The problem is that  
the size of the QLabel doesn't adapt to the size of the layout. This  
happens if my QLabel has a parent widget. If it doesn't have a parent  
widget (i.e. parent widget == 0), that means the QLabel is a window by  
itself, I am not able to obtain the round corners again.

If something is unclear or you need some more clarification on this,  
please feel free to ask.


Thanks for help and with best regards,
Markus Franke
