[Qt-interest] Reg:: QDesktopWidget

[Raja Rokkam]

Hi All,

        Thanks for the help. Lightscreen or any of the below methods wont
help much because I would be needing a bounding rectange alone and the user
should be able to perform any operations on desktop. So essentially the
background widget should be hidden.
