#if in header files

[Leuven, E.]

i would like to have another implementation for IconPalette for qt version 4.2 
and higher, and am wondering how to do this.

now i have the code below in the header file but the compiler doesn't seem to 
like it.

perhaps someone can tell me the way to do this?

thanks!


# if QT_VERSION >= 0x040200

class IconPalette : public QWidgetAction {
 ...
};

# else

class IconPalette : public QWidget {
 ...
};

# endif // QT_VERSION >= 0x040200
