How can I increase the size of a DockWidget in a MainWindow?

[gQt]

Hi all,

I am using Qt 4.3.3 on Debian Linux. The MainWindow in my program has a DockWidget in the rightarea. The DockWidget has QLineEdits (20 rows, 2 columns) added with QGridLayout. During program execursion numbers (QStrings) are displayed in the QLineEdits. The only problem is that the Number strings is to long for the QLineEdits. It is possible to increase the size of the DockWidget area manually by dragging it to the left. My question is: is there a way to make the DockWidget a bit wider or make the RightDockWidgetArea wider?

Thanks in advance!
