Qt 2.x is namespace\-clean, unlike 1.x. 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
|
|
|
|
|
ntqnamespace.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/ttqt20fix 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.
