Re: how to improve the speed of GTK pixmap
Thanks, Sven Neumann I use the GTK1.2 to develop my program. I have not upgrade it to the 2.0 version. I think you are good at the Gtk2.0 now. Would you please give some suggestion to upgrade my program to the new version? Regards Ding Haijun - Dept. of Technology and Development, Nanjing Fujitsu Nanda Software Tech.

how to improve the speed of GTK pixmap
Hi,all I am now trying to use gtk to draw graphic. And I use the double buffer to avoid flicker. In the graphic, I will draw hundreds of line and text. So when I redraw the graphic, it will be very slow. Some advice is gived to me as following: 1. don't use pixmap as the buffer. 2. decrease the times of draw line and draw text. I don't konw to do it. It's will be very kind of you that give some suggestion to improve the speed. Thanks!
