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.
function dumpText() (textdump.h)
Returns a string containing the input text split up in characters
listing category, script, direction etc.
Useful for analyzing non-Latin text.
function dumpTextAsCode() (textdump.h)
Returns a string containing a code snippet creating a QString
by appending the unicode value of character of the input.
This is useful for constructing non-Latin strings with purely ASCII
source code.
class EventFilter (eventfilter.h):
An event filter that logs Qt events to qDebug() depending on
configured categories (for example mouse, keyboard, etc).
function glInfo() (glinfo.h):
Returns a string describing the Open GL configuration (obtained
by querying GL_VENDOR and GL_RENDERER). Available only
when the QT qmake variable contains opengl.
functions dumpNativeWindows(), dumpNativeQtTopLevels():
These functions du,p out the hierarchy of native Windows. Currently
implemented for Windows only.
function dumpAllWidgets() (qwidgetdump.h):
Dumps the hierarchy of QWidgets including information about flags,
visibility, geometry, etc.
function dumpAllWindows() (qwindowdump.h):
Dumps the hierarchy of QWindows including information about flags,
visibility, geometry, etc.
