4 * GUI support by Robert Webb
5 *
6 * Do ":help uganda" in Vim to read copying and usage conditions.
7 * Do ":help credits" in Vim to see a list of people who contributed.

11 * Windows GUI.
12 *
13 * GUI support for Microsoft Windows. Win32 initially; maybe Win16 later
14 *
15 * George V. Reilly <george@reilly.org> wrote the original Win32 GUI.
16 * Robert Webb reworked it to use the existing GUI stuff and added menu,
17 * scrollbars, etc.
18 *
19 * Note: Clipboard stuff, for cutting and pasting text to other windows, is in
20 * os_win32.c. (It can also be done from the terminal version).
21 *
22 * TODO: Some of the function signatures ought to be updated for Win64;
23 * e.g., replace LONG with LONG_PTR, etc.

4572 /* BALLOON-EVAL IMPLEMENTATION FOR WINDOWS.
4573 * Added by Sergey Khorev <sergey.khorev@gmail.com>
4574 *
4575 * The only reused thing is gui_beval.h and get_beval_info()
4576 * from gui_beval.c (note it uses x and y of the BalloonEval struct
4577 * to get current mouse position).
4578 *
4579 * Trying to use as more Windows services as possible, and as less
4580 * IE version as possible :)).
4581 *
4582 * 1) Don't create ToolTip in gui_mch_create_beval_area, only initialize
4583 * BalloonEval struct.
4584 * 2) Enable/Disable simply create/kill BalloonEval Timer
4585 * 3) When there was enough inactivity, timer procedure posts
4586 * async request to debugger
4587 * 4) gui_mch_post_balloon (invoked from netbeans.c) creates tooltip control
4588 * and performs some actions to show it ASAP
4589 * 5) WM_NOTIFY:TTN_POP destroys created tooltip
