Qt now uses very +few global identifiers. Identifiers like red, blue, +LeftButton, AlignRight, Key_Up, Key_Down, NoBrush etc. +are now part of a special class Qt (defined in +qnamespace.h), which is inherited by most Qt classes. +Member functions of classes that inherit from QWidget, +etc. are totally unaffected, but code that is not in +functions of classes inherited from Qt, you must qualify +these identifiers like this: Qt::red, Qt::LeftButton, +Qt::AlignRight, etc. + +The qt/bin/qt20fix script helps to fix the code that +needs adaption, though most code does not need changing. + +Compiling with \-DQT1COMPATIBILITY will help you get going +with Qt 2.x \- it allows all the old "dirty namespace" +identifiers from Qt 1.x to continue working. Without it, +you'll get compile errors that can easily be fixed by +searching this page for the clean identifiers. +.SH "AUTHORS" +.LP +TrollTech -- cgit v1.2.1
