624 | Installs a Qt message handler. Returns a pointer to the message handler␊ |
625 | previously defined.␊ |
626 | ␊ |
627 | The message handler is a function that prints out debug messages,␊ |
628 | warnings and fatal error messages. The Qt library (debug version)␊ |
629 | contains hundreds of warning messages that are printed when internal␊ |
630 | errors (usually invalid function arguments) occur. If you implement␊ |
631 | your own message handler, you get total control of these messages.␊ |
632 | ␊ |
633 | The default message handler prints the message to the standard output␊ |
634 | under X11 or to the debugger under Windows. If it is a fatal message,␊ |
635 | the application aborts immediately.␊ |
636 | ␊ |
637 | Only one message handler can be defined, since this is usually done on␊ |
638 | an application-wide basis to control debug output.␊ |
639 | ␊ |
640 | To restore the message handler, call \c qInstallMsgHandler(0).␊ |
