Re: php-gtk2 ends with an error under linux

Yes, this was only for debuging. To disable: // register_tick_function("ticks"); // declare(ticks=1); mfg xxoes Andrei Zmievski schrieb:

The bug seems to be triggered by the call to gtk_events_pending(). I have no idea what's causing it. Besides, your program is really long. Try cutting it down to the minimum possible one that still reproduces the error and then we'll talk. -Andrei On Feb 12, 2006, at 11:55 PM, xxoes wrote:

This application run perfect under win2k || winXP but not linux The Application is a little bit complex, the error happened on $this->pixmaps->draw_rectangle and the message is: This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 173 error_code 8 request_code 70 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
