class KFontExplorer : public QDialog {
Q_OBJECT
// Usage of the KFontDialog Class:
//
// Case 1) The pointer fontlist is null ( Recommended Usage !!)
//
// In this case KFontDialog will first search
// for ~/.kde/config/kdefonts. If kdefonts if available
// it will insert the fonts listed there into the family combo.
//
// Note: ~/.kde/config/kdefonts is managed by kfontmanager.
// ~/.kde/config/kdefonts is a newline separated list of font names.
// Such as: time\nhelvetica\nfixed\n etc.You should however not
// manipulate that list -- that is the job of kfontmanager.
//
// If ~/.kde/config/kdefonts doesn't exist, KFontDialog will query
// the X server and insert all availabe fonts.
//
// Case 2) The pointer fontlist is non null. In this cae KFontDialog
// will insert the strings of that QStrList into the family combo.
//
// Note: Due to a bug in Qt 1.2 you must
// supply at this point at least two fonts in the QStrList that
// fontlist points to. The bug has been reported and will hopefully
// be fixed in Qt.1.3.
