- \relates TQApplication
-
- Installs a TQt message handler \a h. Returns a pointer to the
- message handler previously defined.
-
- The message handler is a function that prints out debug messages,
- warnings and fatal error messages. The TQt library (debug version)
- contains hundreds of warning messages that are printed when
- internal errors (usually invalid function arguments) occur. If you
- implement your own message handler, you get total control of these
- messages.
-
- The default message handler prints the message to the standard
- output under X11 or to the debugger under Windows. If it is a
- fatal message, the application aborts immediately.
-
- Only one message handler can be defined, since this is usually
- done on an application-wide basis to control debug output.
-
- To restore the message handler, call \c tqInstallMsgHandler(0).
-
- Example:
- \code
- #include <tqapplication.h>
- #include <stdio.h>
- #include <stdlib.h>
-
- void myMessageOutput( TQtMsgType type, const char *msg )
- {
- switch ( type ) {
- case TQtDebugMsg:
- fprintf( stderr, "Debug: %s\n", msg );
- break;
- case TQtWarningMsg:
- fprintf( stderr, "Warning: %s\n", msg );
- break;
- case TQtFatalMsg:
- fprintf( stderr, "Fatal: %s\n", msg );
- abort(); // deliberately core dump
- }
- }
-
- int main( int argc, char **argv )
- {
- tqInstallMsgHandler( myMessageOutput );
- TQApplication a( argc, argv );
- ...
- return a.exec();
