Set background pixmap for widget that will be parent for your elements by using setPaletteBackgroundPixmap

Version Qt-2.3.2

Try using setBackgroundPixmap() for your widget.

    QPixmap pixmap = image;    
    this->setPaletteBackgroundPixmap ( pixmap );
 
    as = new QListBox( this );
    g->addWidget( as, 1, 1 );
    as->resize(25,30);

If you use layouts, you shouldn't try to change widget's size. If you really need to, you can try to force the widget to change its sizeHint() (but you'll probably have to subclass).

I didnt get u? Can you explain?

I cant understand you....if you want resize your elements manually why are you use layouts?
Layout its mechanizm that take care about resize from users sholders, and you cant call resize by own.

I displayed a list box, and two Push Buttons on my window. List box grows from starting i specified to the
point just top of one of the Push Button. I just want to reduce the size of the listbox so that it looks neat on
the Screen.

So try setting the maximum size the box can take. This way it'll not expand more. Or change the size policy to Maximum or Preffered.
