setting a window background...

[nupul]

How can you set the widow background of the app window to any image format supported by Qt.

Eg...say I am using a List View...and wish that the contents are displayed in the window with the background set to say "ship.jpg" rather than the usual white space?

Similarly is it also possible to tile a "background image" horizontally along the length of a toolbar or a popup menu?

Also I have seen in windows explorer (Xp Pro) that there is a water mark present at the bottom right of the window....can i achieve the same with Qt?

I'd appreciate a sample code if possible...

Thanks
