| 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) | |
