// TQT TODO:
// 1. TQLayout and TQGridLayout addItem functions may not be able to be subclassed by TQt classes
//    This will probably require an inline redirect from the Qt4 method addItem(QLayoutItem) to the TQt method addItem(TQLayoutItem)
//    See also TQLayout::setGeometry() for an example of how to do this
//    See tqlayout.cpp line 3074 for why this is needed
//    MAYBE?????
