| 10 * os_win32.c | |
| 11 * | |
| 12 * Used for both the console version and the Win32 GUI. A lot of code is for | |
| 13 * the console version only, so there is a lot of "#ifndef FEAT_GUI_W32". | |
| 14 * | |
| 15 * Win32 (Windows NT and Windows 95) system-dependent routines. | |
| 16 * Portions lifted from the Win32 SDK samples, the MSDOS-dependent code, | |
| 17 * NetHack 3.1.3, GNU Emacs 19.30, and Vile 5.5. | |
| 18 * | |
| 19 * George V. Reilly <george@reilly.org> wrote most of this. | |
| 20 * Roger Knobbe <rogerk@wonderware.com> did the initial port of Vim 3.0. | |

| 934 * or a MOUSE_LEFT, _MIDDLE, or _RIGHT. We encode the button type, | |
| 935 * the number of clicks, and the Shift/Ctrl/Alt modifiers in g_nMouseClick, | |
| 936 * and we return the mouse position in g_xMouse and g_yMouse. | |
| 937 * | |
| 938 * Every MOUSE_LEFT, _MIDDLE, or _RIGHT will be followed by zero or more | |

| 940 * by MOUSE_LEFT, _MIDDLE, or _RIGHT. | |

| 946 * moves, even if it stays within the same character cell. We ignore | |
| 947 * all MOUSE_MOVED messages if the position hasn't really changed, and | |
| 948 * we ignore all MOUSE_MOVED messages where no button is held down (i.e., | |
| 949 * we're only interested in MOUSE_DRAG). | |
| 950 * | |
| 951 * All of this is complicated by the code that fakes MOUSE_MIDDLE on | |
| 952 * 2-button mouses by pressing the left & right buttons simultaneously. | |
| 953 * In practice, it's almost impossible to click both at the same time, | |
| 954 * so we need to delay a little. Also, we tend not to get MOUSE_RELEASE | |
| 955 * in such cases, if the user is clicking quickly. | |
