This is a collection of functions and classes helpful for diagnosing bugs
|
|
|
|
|
in Qt 4 and Qt 5. It can be included in the application's .pro file by
|
|
|
|
|
adding:
|
|
|
|
|
|
|
|
|
|
include([path to Qt sources]/tests/manual/diaglib/diaglib.pri)
|
|
|
|
|
|
|
|
|
|
For Qt 4, the environment variable QTDIR may be used:
|
|
|
|
|
include($$(QTDIR)/tests/manual/diaglib/diaglib.pri)
|
|
|
|
|
|
|
|
|
|
The .pri file adds the define QT_DIAG_LIB, so, diagnostic
|
|
|
|
|
code can be enlosed within #ifdef to work without it as well.
|
|
|
|
|
|
|
|
|
|
All functions and classes are in the QtDiag namespace.
