Dialog

Hi guys...again me...I've desgined a dialog TO which I add/remove widget upon clicking on particular add/remove button (widgets add it to it are added on fly right after I click on add button...they are removed right after I click remove button and widgets have its checkbox checked)...the problem is that the groupbox in which the new widgets are added changes its size only when adding them but when I remove a widget(s) it preserves its size and dont decreases it accordingly...
Is there a property that has to be set so it would decrease its size when a widget is removed from that groupbox ? it increases its size when the new widget is added...but not decrease accordingly its size when a widgets is/are removed
Thanks
I designed that dialog with qtdesigner and the widget that is added to dialogs GroupBox too

I tried to set the size policy to minimum and so on but it didnt work...

It should work out of the box. There must be something wrong with your code. Did you remember to apply a layout to the dialog?

yes I did...I even managed to fix this problem with setting one of the layout's attributes:
setSizeConstraint(QLayout::SetMinAndMaxSize);
but you have to set the min and max sizes of your widgets...

You meant the dialog was not shrinking? I thought you meant the groupbox... Yes, the dialog won't shrink by itself without applying a constraint on the top level layout.
