    Well not a whole column, but a single item in the grid. I could add more buttons to the layout for testing purposes, but since a picture is worth a thousand words, I think the link explains what's my issue quite well.

    Yes pictures made it very clear.
    Try to reproduce it in Creator. Its seems to
    rearrange.

      Do you mean to make the form in the designer? Unfortunately, in this case this is not an option, see the linked thread for details as to why.

        I know u cant use UI file.
        Im just wondering why in creator,
        if I create a grid 3x2 with buttons.
        Then from code, i take() and delete say button 3, i
        get no holes. But in AgDial there is.
        I should get the same, shouldn't I?

          I suppose so. But I'm not takeing the item itself, maybe this is why the behavior differs. I'll try it out.
          Nope, substituting the relevant reinsertion code with:

          	delete layout->takeAt(index);
          	delete button;
          	buttons.erase(i);
          

          Produces the same hole. I have no idea why this works in your case ...

            Just to be sure, we are talking
            about a normal gridlayout in a widget?
            At runtime, there should be no difference between one from
            UI files and one from code.
            So your case must be different or mine too simple.

              Absolutely! Here's how a create a page:

              bool AgDialPrivate::createPage(QAction * action)
              {
              	Q_ASSERT(action);
              	QList<QAction *> children = action->findChildren<QAction *>(QString(), Qt::FindDirectChildrenOnly);
              	if (children.count() <= 0 || pages.value(action, NULL))
              		return false;
              
              	// Create a page for this action
              	AGUI_Q(AgDial);
              
              	QWidget * page = new QWidget(q);
              	new QGridLayout(page);
              
              	pages.insert(action, page);
              	q->addWidget(page);
              
              	// Create a return button
              	QAction * parent = qobject_cast<QAction *>(action->parent());
              	createReturnButton(page, parent);
              
              	// If the action has any children, create their buttons and/or pages
              	foreach (QAction * child, children)  {
              		createButton(child);
              		if (child->children().count() > 0)
              			createPage(child);
              	}
              
              	// Map the triggered signal of the child action
              	QSignalMapper * mapper = new QSignalMapper(page);
              	mapper->setMapping(action, page);
              	QObject::connect(action, SIGNAL(triggered()), mapper, SLOT(map()));
              	QObject::connect(mapper, SIGNAL(mapped(QWidget *)), q, SLOT(setCurrentWidget(QWidget *)));
              
              	return true;
              }

                Ok, i delete sample and tried again.
                Now I get hole too! ?
                only difference is that I had min/max heights in other test.

                    Maybe the layout's redistribution of item space had hidden the effect in the previous test? I couldn't think of another reason.

                      I agree . must been something like that as now the effect
                      is 100% as your experience. Even in designer.
                      Sorry for the confusion.
