Debugging in Qt program in Qt Creator

Swati777999

Hi All,

I have recently started learning Qt and using Qt Creator IDE. I would like to know ways to debug a program [apart from putting commands for display through debug() .

Thanks in advance!

Dont quite understand your question.
You debug by starting your debugger... set breakpoints, check function calls / stack trace or content of your pointers and variables...
Depends on what happens. If your program crashes or if it's not doing what you expect.

I have added the following to my .pro file .

message ("removed all subdirs here Nov 17 no differnce ")

SUBDIRS += \
#    ../../../../../BACKUP/CAT-28-3/PROJECTS/CAT_FT857_BLUETOOTH/CAT_FT857_BLUETOOTH_MAIN_PROJECT/TEST_MDI/TEST_MDI.promessage(:dupressdd complier warningsd  \
#    ../../EXAMPLES_COPY_5.x/Examples/Qt-6.2.0/bluetooth/btchat/btchat.pro \
#    ../../Examples/Qt-5.15.2/bluetooth/btscanner/btscanner.pro
message("supress all warnings ")
QMAKE_CXXFLAGS += -w
#QMAKE_CXXFLAGS_WARN_OFF
message ("verbose output compiler ")
QMAKE_LFLAGS += -v
message ("verbose output linker ")
QMAKE_CXXFLAGS += -Wl, --verbose

message (" disable qDebug messages")
#//CONFIG += console
#DEFINES += QT_NO_DEBUG_OUTPUT

It is somewhat redundant or stupid , take your pick.
I use heavily

#ifdef BYPASS
useless old code but sometime prevents making same mistake
#endif

then old stand by
#define DEBUG

#ifdef DEBUG
trace / debug notes
....
#endif

Best debug tool

for(;;)
comment your code

PS
Anybody care to add how to "remove all break points", senior moment.

I cannot be held responsible for the messed-up text...
