QFileDialog disable buttons

[Qt Coder]

Hello all,


I m using Qt 4.4.3


I m using QFiledialog in my application to allow user to select images .

I hav done with above functionality ,now I want to add following things to QFileDialog


User should only be able to select images from "Dir" set at start.

dialog.setDirectory(QDir(Dir));  .

dialog.setDirectory(QDir(Dir));  .

To copy to clipboard, switch view to plain text mode 

so Move up/Down /back/Create new folder/Show Path Heirarchy ,buttons of FileDialog should be disabled so that user wont be able to navigate to other folders


how to acheive this?
