<div dir="ltr">the code of julia.c doesn't help me because it use XCBImagePutPixel  and the color is directly given in parameter, but I'm drawing directly in the window using xcb_poly_segment, xcb_poly_point... and the color can't be given directly. That's why i'm looking to a function corresponding to XSetForeground to select the color i want.<br> I hope i'm clear enough, else i'll try to simplify my program to post it here when i have time.<br><br><div class="gmail_quote">2008/8/7 Vincent Torri <span dir="ltr"><<a href="mailto:vtorri@univ-evry.fr">vtorri@univ-evry.fr</a>></span><br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br> Hey,<div><div></div><div class="Wj3C7c"><br> <br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I started few days ago a gui creation with Xlib, but i found xcb yesterday<br> and decided try it.
