21 * NOTES
22 *
23 * This code was audited for completeness against the documented features
24 * of Comctl32.dll version 6.0 on Sep. 08, 2004, by Robert Shearman.
25 *
26 * Unless otherwise noted, we believe this code to be complete, as per
27 * the specification mentioned above.
28 * If you discover missing features or bugs please note them below.
29 *
30 * TODO:
31 * - Custom draw support.
32 * - Animation.
33 * - Links.
34 * - Messages:
35 * o TTM_ADJUSTRECT
36 * o TTM_GETTITLEA
37 * o TTM_GETTTILEW
38 * o TTM_POPUP
39 * - Styles:
40 * o TTS_NOANIMATE
41 * o TTS_NOFADE
42 * o TTS_CLOSE
43 *
44 * Testing:
45 * - Run tests using Waite Group Windows95 API Bible Volume 2.
46 * The second cdrom (chapter 3) contains executables activate.exe,
47 * curtool.exe, deltool.exe, enumtools.exe, getinfo.exe, getiptxt.exe,
48 * hittest.exe, needtext.exe, newrect.exe, updtext.exe and winfrpt.exe.
49 *
50 * Timer logic.
51 *
52 * One important point to remember is that tools don't necessarily get
53 * a WM_MOUSEMOVE once the cursor leaves the tool, an example is when
54 * a tool sets TTF_IDISHWND (i.e. an entire window is a tool) because
55 * here WM_MOUSEMOVEs only get sent when the cursor is inside the
56 * client area. Therefore the only reliable way to know that the
57 * cursor has left a tool is to keep a timer running and check the
58 * position every time it expires. This is the role of timer
59 * ID_TIMERLEAVE.
60 *
61 *
62 * On entering a tool (detected in a relayed WM_MOUSEMOVE) we start
63 * ID_TIMERSHOW, if this times out and we're still in the tool we show
64 * the tip. On showing a tip we start both ID_TIMERPOP and
65 * ID_TIMERLEAVE. On hiding a tooltip we kill ID_TIMERPOP.
66 * ID_TIMERPOP is restarted on every relayed WM_MOUSEMOVE. If
67 * ID_TIMERPOP expires the tool is hidden and ID_TIMERPOP is killed.
68 * ID_TIMERLEAVE remains running - this is important as we need to
69 * determine when the cursor leaves the tool.
70 *
71 * When ID_TIMERLEAVE expires or on a relayed WM_MOUSEMOVE if we're
72 * still in the tool do nothing (apart from restart ID_TIMERPOP if
73 * this is a WM_MOUSEMOVE) (ID_TIMERLEAVE remains running). If we've
74 * left the tool and entered another one then hide the tip and start
75 * ID_TIMERSHOW with time ReshowTime and kill ID_TIMERLEAVE. If we're
76 * outside all tools hide the tip and kill ID_TIMERLEAVE. On Relayed
77 * mouse button messages hide the tip but leave ID_TIMERLEAVE running,
78 * this again will let us keep track of when the cursor leaves the
79 * tool.
80 *
81 *
82 * infoPtr->nTool is the tool the mouse was on on the last relayed MM
83 * or timer expiry or -1 if the mouse was not on a tool.
84 *
85 * infoPtr->nCurrentTool is the tool for which the tip is currently
86 * displaying text for or -1 if the tip is not shown. Actually this
87 * will only ever be infoPtr-nTool or -1, so it could be changed to a
88 * BOOL.
