Qt Creator 2.0 and central control not expanding

[Suppaman]

Hi all

I'm intruducing to Qt world. Currently I'm studing teh Qt Creator tool for a project I want to develop using Qt libraries. I need to create an SDI main window with a Lisi View control in the client area. My problem is I still didn't understand how to make this List View control automatically expanded over all the window client area also if the main window is manually resized by the user. Using Qt Creator Design I dropped the List View control over the windows client area (as result my control is child of centraWidget). Then I set the horizontal and vertical sizePolicy as "Expanding" but nothing happens. The control remain in the center of the client area and maintain its original size also when execute the compiled software.
I'm sure I missed something of really stupid but I still didn't find what.
Someone can give me a suggestion?

Thank you

Hi
Either you can check out the setMaxSize documentation of QWidget
or
You can override the resizeEvent function of the widget which is holding the list box control.Then set the geometry of the listbox by reading the holder widget rect().

You need to apply a layout on the top-level widget. Click on an empty area in the widget and click one of the layout buttons in the toolbar.
