| /* |
| * Structure of the BeOS GUI code: |
| * |
| * There are 3 threads. |
| * 1. The initial thread. In gui_mch_prepare() this gets to run the |
| * BApplication message loop. But before it starts doing that, |
| * it creates thread 2: |
| * 2. The main() thread. This thread is created in gui_mch_prepare() |
| * and its purpose in life is to call main(argc, argv) again. |
| * This thread is doing the bulk of the work. |
| * 3. Sooner or later, a window is opened by the main() thread. This |
| * causes a second message loop to be created: the window thread. |
| * |
| * == alternatively === |
| * |
| * #if RUN_BAPPLICATION_IN_NEW_THREAD... |
| * |
| * 1. The initial thread. In gui_mch_prepare() this gets to spawn |
| * thread 2. After doing that, it returns to main() to do the |
| * bulk of the work, being the main() thread. |
| * 2. Runs the BApplication. |
| * 3. The window thread, just like in the first case. |
| * |
| * This second alternative is cleaner from Vim's viewpoint. However, |
| * the BeBook seems to assume everywhere that the BApplication *must* |
| * run in the initial thread. So perhaps doing otherwise is very wrong. |
| * |
| * However, from a B_SINGLE_LAUNCH viewpoint, the first is better. |
| * If Vim is marked "Single Launch" in its application resources, |
| * and a file is dropped on the Vim icon, and another Vim is already |
| * running, the file is passed on to the earlier Vim. This happens |
| * in BApplication::Run(). So we want Vim to terminate if |
| * BApplication::Run() terminates. (See the BeBook, on BApplication. |
| * However, it seems that the second copy of Vim isn't even started |
| * in this case... which is for the better since I wouldn't know how |
| * to detect this case.) |
| * |
| * Communication between these threads occurs mostly by translating |
| * BMessages that come in and posting an appropriate translation on |
| * the VDCMP (Vim Direct Communication Message Port). Therefore the |
| * actions required for keypresses and window resizes, etc, are mostly |
| * performed in the main() thread. |
| * |
| * A notable exception to this is the Draw() event. The redrawing of |
| * the window contents is performed asynchronously from the window |
| * thread. To make this work correctly, a locking protocol is used when |
| * any thread is accessing the essential variables that are used by |
| * the window thread. |
| * |
| * This locking protocol consists of locking Vim's window. This is both |
| * convenient and necessary. |
