Maximize widget upon main window maximize [Solved]

[zvivered]

Hello,

I have one widget (tree) in the main window.

I want that it will always be maximixed to the size of the main window when the main window is resized (and upon application launch).
Can you help ?

Thanks,
Zvika

You probably didn't use "a layout":http://qt-project.org/doc/qt-4.7/layout.html

Dear Eddy,

I wrote the following code:
@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QHBoxLayout *mainLayout = new QHBoxLayout;
mainLayout->addWidget(ui->treeWidget);
setLayout(mainLayout);

}
@
But the tree widget is not resized upon window resize.

Can you help ?
Thanks,
Zvika.

[edit: please add @code tags around your code next time. It makes it easier to read for us, eddy]

At first sight your code looks ok. Are you saying that your border of the treeWidget is not following the size or the contents of the treeWidget don't behave as expected?

[Edit maybe "resizeColumnToContents.":http://qt-project.org/doc/qt-4.8/qtreeview.html#resizeColumnToContents
Is what you need]

No, the code is wrong.

@
setLayout(mainLayout)
@

will failed here, as QMainWindow already has a Layout. (Otherwise, how can QMenuBar, QStatusBar and QToolBar s work?)

You don't need to write such code, just put QTreeWidget to your central Widget, then apply a layout for it. All this can be done in Designer.

Dear Members,

I did it with the designer.
It works fine.

Thanks,
