Hi, While "studying scribble-simple.c" given in the demos, I saw sth like /* gdk_draw_rectangle (pixmap, widget->style->black_gc, TRUE, update_rect.x, update_rect.y, update_rect.width, update_rect.height); */ Here, widget->style->black_gc can only draw black color. Then,how can I draw with other colors? As it is mentioned in the tutorial that it's better to draw on a pixmap first, then copy this backing pixmap to the drawing area. whether a pixmap only has black and white color? Does it mean that I should draw directly on the drawing area but not using a pixmap? Thanks very much! Zeng 使用新一代 Windows Live Messenger 轻松交流和共享！ 立即体验！ |
