About Qt designer

Sorry I didn't respond so quickly issues in RL.

If you wanna do it without spacers. Just edit the minimumSize and maximumSize properties. But I use spacers like crazy ;P. The just resize the form in designer and it will fix. But yeah the spacer at the bottom of the form is forcing everything up. So when you add a new QGroupBox to the form it will make it into a single tiny thing. Just delete the spacer at the bottom and resize the form and when you are done just add another. But I don't recommand spacers because it limits stuff that shouldn't be. Especially when forms are resizeable.

The reason for the splitting of the buttons is because the vertical sizePolicy was set to expanding. instead of fixed. So when you set it to fix it will not grown aka not have the gap between the OK and Cancel button. Oh in that little code you post. If you click on the ButtonBox and look through the properties you can see that you can add more buttons to it that way.
