Re: php-gtk2 ends with an error under linux

I don't think this is a PHP-GTK specific problem. The issue seems to be in your usage of $widget->style->white_gc. Somehow, it is incompatible with the drawable. I think you have to create a GdkGC via: $gc = new GdkGC($this->pixmaps); Then fill in its values and use it. -Andrei On Feb 13, 2006, at 11:33 PM, xxoes wrote:

This is a short version. if i set the depth of $this->pixmaps to 1, php-gtk crash/ends. I require depth 1 because i willl use shape_combine_mask for transparent background.

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.
