[quickNitin]

this is in continuoation to post http://www.qtcentre.org/forum/f-newbie-4/t-setting-i-widgt-visibleinvisible-on-toggling-of-button-4550.html

Issue i am facing is auto resizing of this dialog.
I have put these widget in a grid layout ( tried other layout also).
I am wishing that my tab widgets remain of same size and whenever i try to display table widgets ,dialog form may enlarge/shorten correspondingily but this is not happening.
I was expecing layout to take care of this. I also tried wih some some size policy but couldn't get desired result.

You are most likely missing the top level layout. Open up context menu over the dialog's background and select "Layout->Something" or alternatively do that from the Form-menu in the main menu bar (make sure you click on the dialogs background before so that no child widget is selected).

widgets were already in grid layout and had done what you suggested. Ifound a example very similar to one i am doing except one line of code



layout()->setSizeContraints(QLayout::setFixedSize)


This line did the trick. What i understood from this code layout manager allows only that much space which is minimum require. After that it expands / shrinks accordingly. Senior members kindly comment.

Also if i donot follow the steps what u had suggested , this line results in segmentation fault since layout() for that widgets returns 0.

Hi,
I was struggling with this problem for the last 2 days and your posting has helped me a lot. But this SetFixedSize confused a bit, although it fixes the size of dialog box but also resizes it to the enclosing widget's size.

What's the point of having a fixed size dialog that doesn't show all its content?
