About Qt designer

[HelloDan]

If you want to prevent the boxes from expanding vertically, restrict it with one of the properties, don't use spacers. Is just neater and easier to work with.

It's hard to understand. How to do? If I don't add one more spacer, the QGroupBox will be compressed to a line, but it will still add two more cells.

Can anyone help?

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.

Thanks!

But that is one more problem. Compare with you example, the latter UI file i upload and do the same things with your example, but that is two cell in my Ui file, but your just one with a spacer. How I can merge my two cell into one just as you did.

Thanks again!

Depending on which one. Just pull on one of the ends that you want it to go into the next column or row and just pull on it and it will span to the next column|row
