New to QSplitter

[bruccutler]

Hello,
I have two controls, one a QTreeWidget and another a QStackedDialog.

When I add these to a QSplitter and I attempt to drag the splitter, it flashes, but goes back to the original size. If I drag it far enough, the whole screen is replaced either by the left side or the right side, but I can't get it to stretch. I'm adding QGroupBoxes to the splitter, could that be my problem?

Here's my code snippet:

QSplitter *splitter = new QSplitter(this);
splitter->addWidget(m_pNavGroupBox); // QGroupBox
splitter->addWidget(m_pDataGroupBox); // QGroupBox
splitter->setStretchFactor(0, 10);
splitter->setStretchFactor(1, 10);

QVBoxLayout *pMainLayout = new QVBoxLayout();
pMainLayout->addWidget(m_pTitleImageLabel, 3, Qt::AlignCenter); // label -
pMainLayout->addWidget(splitter);

setLayout(pMainLayout); // for main window

I hate to keep answering my own questions, but just in case someone else tries this, I had a tabbed dialog on the right hand side that had a tab that would not shrink, so, until I increased the size of the window, I couldn't drag the splitter bar. Once I eliminated that particular tab, I found that I could move it.

In my case I had stacked dialogs and the dialogs had tabbed dialogs underneath and one of the tabbed dialogs wouldn't fit in a smaller area, so none of them would.

I am running into the same problem. It has to do with layouts in the tabs.

I have a tab widget in one part of my splitter. As long as I have a layout in the tabs, I cannot make the splitter shrink that side. I need the layouts because I want the tab to look nice but is there any way to tell it that it can shrink that side?

I have a QMdiArea on the other side and I am able to shrink that side.

Thanks.

Hi
Maybe some of the widgets' minimum size(hint) is too great, so that the layout prevents the splitter from further shrinking them.
Hope this helps.

I checked and I have no minimum sizes on any of the widgets and I set all the policies to preferred. (The only things I left as expanding were the spacers.)

I even created a minimumSizeHint() method to return (0,0) for each of the tabs but that didn't make a difference.

Thanks for the suggestions.

Did you create the form in designer? Sometimes spacers get relatively large size hint values while working with designer. I suggest you to go through spacers and check their size hints.

Somewhere along the way my tabWidget->setMinimumWidth(20); got deleted. Putting that back in fixed it. I have set my layouts to be minimum, minimumExpanding, and a few preferred. I also have removed all minimumWidths. I think the combination of all three solved the problem.
