14 | * The color situation is a total flying circus. The X approach to | ||
15 | * device independence is to treat everything like a MicroVax framebuffer | ||
16 | * on acid. A truely portable X application is required to act like the | ||
17 | * persistent customer in the Monty Python ``Cheese Shop'' sketch. Even | ||
18 | * the simplest applications must answer many difficult questions, like: | ||
19 | * | ||
20 | * WHAT IS YOUR DISPLAY? | ||
21 | * display = XOpenDisplay("unix:0"); | ||
22 | * WHAT IS YOUR ROOT? | ||
23 | * root = RootWindow(display, DefaultScreen(display)); | ||
24 | * AND WHAT IS YOUR WINDOW? | ||
25 | * win = XCreateSimpleWindow(display, root, 0, 0, 256, 256, 1, | ||
26 | * BlackPixel(display, DefaultScreen(display)), | ||
27 | * WhitePixel(display, DefaultScreen(display))) | ||
28 | * OH ALL RIGHT, YOU CAN GO ON. | ||
29 | * | ||
30 | * WHAT IS YOUR DISPLAY? | ||
31 | * display = XOpenDisplay("unix:0"); | ||
32 | * WHAT IS YOUR COLORMAP? | ||
33 | * cmap = DefaultColormap(display, DefaultScreen(display)); | ||
34 | * AND WHAT IS YOUR FAVORITE COLOR? | ||
35 | * favorite_color = 0; / * Black. * / | ||
36 | * / * Whoops! No, I mean: * / | ||
37 | * favorite_color = BlackPixel(display, DefaultScreen(display)); | ||
38 | * / * AAAYYYYEEEEE!! (client dumps core & falls into the chasm) * / | ||
39 | * | ||
40 | * WHAT IS YOUR DISPLAY? | ||
41 | * display = XOpenDisplay("unix:0"); | ||
42 | * WHAT IS YOUR VISUAL? | ||
43 | * struct XVisualInfo vinfo; | ||
44 | * if (XMatchVisualInfo(display, DefaultScreen(display), | ||
45 | * 8, PseudoColor, &vinfo) != 0) | ||
46 | * visual = vinfo.visual; | ||
47 | * AND WHAT IS THE NET SPEED VELOCITY OF AN XConfigureWindow REQUEST? | ||
48 | * / * Is that a SubStructureRedirectMask or a ResizeRedirectMask? * / | ||
49 | * WHAT?! HOW AM I SUPPOSED TO KNOW THAT? | ||
50 | * AAAAUUUGGGHHH!!!! (server dumps core & falls into the chasm) | ||
