Qt resize child Window...

[Peppy]

Hi, I have this problem:
How to resize child tab widget which width must be 100% of MainWindow width...I tried: setGeometry(QRect(0,0,rect().width(),150)); But it just set up this width, when I resize window MainWindow, inherited by QMainWindow, then width is constant...do you have any solutions...I was looking on the google and nothing...

I don't know if you want to do this but... Why don't you lay out the tab widget?

It still doesn't work ...I used QVBoxLayout and it doesn't work...do you have any idea how can I do it?

I think that your code is incomplete.

This works for me:

horizontalLayout = new QHBoxLayout();
tabWidget = new QTabWidget();
tab = new QWidget();
tabWidget->addTab(tab, QString());
tab_2 = new QWidget();
tabWidget->addTab(tab_2, QString());
horizontalLayout->addWidget(tabWidget);

horizontalLayout = new QHBoxLayout();
tabWidget = new QTabWidget();
tab = new QWidget();
tabWidget->addTab(tab, QString());
tab_2 = new QWidget();
tabWidget->addTab(tab_2, QString());
horizontalLayout->addWidget(tabWidget);

To copy to clipboard, switch view to plain text mode 

Then you can set sizePolicy and/or max-min Size for the tabWidget (or add vertical spacer) if you don't want to lay out all the height.
