Dear Greger Haga and other friend,
     I have read the source code of QPopupMenu and some other classes.
QPopupMenu inherits QFrame and QMenuData, QFrame inherits QWidget. In the
function QPopupMenu::QPopupMenu(), there is a fuction setBackgroundMode(
PaletteButton ), and I found that it's a member function of QWidget. Then I
read the source code of QWiget, in it I found an enum BackgroundMode and
setBackgroundMode(BackgroundMode).

enum BackgroundMode { FixedColor, FixedPixmap, NoBackground,
                 PaletteForeground, PaletteButton, PaletteLight,
                 PaletteMidlight, PaletteDark, PaletteMid,
                 PaletteText, PaletteBrightText, PaletteBase,
                 PaletteBackground, PaletteShadow, PaletteHighlight,
                 PaletteHighlightedText, PaletteButtonText,
                 X11ParentRelative };

     But I don't know what the every variable of BackgroundMode means? Who
help me?
     Thanks in Advance.
