auto resize component in main window when main windows is resized

Dear all, I know this is kind of newbie question. But I tried to search forum but can not find the solution. Below is the capture of my main windows.

http://www.qtcentre.org/forum/attach...1&d=1218381404

Basically the left hand side is a label(please select file....) and right hand side is a tab. When user use this application and change the size I want the label to expand horizontally and vertically to fit the screen. And the tab to expand vertically. Can anyone suggest me how to do that ??

And if possible, can I hide the tab first and when people move the mouse near it then show it ( like a windows autohide task bar ) ???

thank in advance

change sizePolicy for tabWidget Horizantal=Fixed.

I tried, that would fix the tab. But how to automatically expand it(vertically) when user change the main windows size ?

did you put label and tab in layout?

No. And I just tried to put label and tab in horizontal layout. But no different. It is still not expand automatically when main windows is expand.

can you post ui-file?

Dear spirit, I have attached my ui file. Thank a lot for helping :D

is than what you need?

sorry, I forgot one more: in SizePolicy of tabWidget you should set next values:
hSizeType == Fixed (was initial)
vSizeType == Preferred

Thank a lot spirit !! It's work. :D:D:D:D

Can you explain what I did wrong -.-

you set layout for label and tabWidget wrong. you would better click on widget and select "Lay out->Lay out Horizantally" from context menu.

Thank again spirit :D
