Problem with QSplitter - won't resize widgets? [Fixed]

[LiamMaru]

I'm trying to get QSplitter to work with a simple aggregate widget, created as follows:

@ // Assemble small area for tree view and etc.
QWidget* leftWidget = new QWidget();
QVBoxLayout* leftLayout = new QVBoxLayout();
leftWidget->setLayout(leftLayout);
leftLayout->addWidget(StepsTreeView);@

However, the created widget doesn't occupy the space the splitter allows it to:

Any ideas?

How about setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Minimum)

Tried the following:

@
// Assemble small area for tree view and etc.
QWidget* leftWidget = new QWidget();
QVBoxLayout* leftLayout = new QVBoxLayout();
leftWidget->setLayout(leftLayout);
leftWidget->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Minimum);
leftLayout->addWidget(StepsTreeView);@

Same result.

Hmmh, I looked your picture, but I can't see the splitter bar, so I could know which of the widgets do not resize. In your picture, it seems that both widgets (treeview and notebook) are happy with their sizes.

I search for these kind of problems by changing item's background colors e.g yellow (setStyleSheet("background-color: yellow;");), and watch what widget/layout does not resize.

Furthermore, it would be nice to see the code with QSplitter, too.

Here's the code to setup the splitter:

@QSplitter* tableSplitter = new QSplitter();@

And here's the code where I place widgets in the splitter:

@ // Assemble the splitter.
tableSplitter->addWidget(leftWidget);
tableSplitter->addWidget(EditWidget);@

I've highlighted in the image where the wasted space is. The splitter bar is the the right of that.

The code should work. Can you provide a complete, compilable test case that we can look into?

Okay, I'll put one together later today.

Aaaargh, just found out one of my team members added a QSizePolicy::Fixed in the wrong spot ><.
