[Interest] QGroupBox Subclass
I am currently using a QGroupBox (with some custom style sheets) as a superclass for a custom widget in our program. QGroupBox has the isCheckable property which we use then style with a custom image for an icon and over ride the toggled to get some custom actions when the user clicks the button. We would like to be able to add a few more buttons to the QGroupBox to perform some other actions. I took at the source code for QGroupBox to try and figure out where the layout was being performed and I would have to say I understand generally what is going on but I can not figure out where the actual QCheckBox is being added to the layout for the QGroupBox. My Question is: Could some nice developer just give me a nudge in the right direction as to where the actual layout of the QGroupBox is being performed and where the QCheckBox is instantiated? I think I can figure it out from there. Thanks so much. Mike Jackson (dream3d.bluequartz.net) ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

The checkbox is drawn and handled in conjunction with the style as a QStyle::SubControl. See QGroupBox.event for the details (around line 330 in 4.8.4). I think you need to override QProxyStyle to force extra space between the existing checkbox and label. Please let the list know how you go, as I may need to do something similar myself.

Regards, Tony Thanks for the hint. I got much farther and deeper into QStyle, QStyleOption and QCommonStyle and how the painting is proceeding from there. I think this probably is not the route I can take as there is a lot there that I would have to reimplement in code that I would have to generate. I'll take another stab at starting with a QWidget and going from there. THanks for the nudge.
