How to set the BORDER COLOR of QDialog?

[wysota]

You can get rid of the frame by using QWidget::setMask() or by removing all the decorations by setting the FramelessWindowHint before showing the window. Either way this will remove the frame, not change its colour.

Dear Sir!
That means frames colour cann't be changed in Qt4.

That's what I said in the beginning

You can't influence the frame colour using any toolkit. This is not Qt specific. The only way to fake it is to make your window frameless, then draw the titlebar and frame manually. Some windows apps tend to do this. That's usually a bad idea though, since users won't like your non-standard app, and you have to reimplement things like window movement and minimize/maximize/close buttons yourself. Lots of work for a minor cosmetic issue.
