Therefore the only reliable way to know that the * cursor has left a tool is to keep a timer running and check the * position every time it expires. This is the role of timer * ID_TIMERLEAVE. * * * On entering a tool (detected in a relayed WM_MOUSEMOVE) we start * ID_TIMERSHOW, if this times out and we're still in the tool we show * the tip. On showing a tip we start both ID_TIMERPOP and * ID_TIMERLEAVE. On hiding a tooltip we kill ID_TIMERPOP. * ID_TIMERPOP is restarted on every relayed WM_MOUSEMOVE. If * ID_TIMERPOP expires the tool is hidden and ID_TIMERPOP is killed. * ID_TIMERLEAVE remains running - this is important as we need to * determine when the cursor leaves the tool. * * When ID_TIMERLEAVE expires or on a relayed WM_MOUSEMOVE if we're * still in the tool do nothing (apart from restart ID_TIMERPOP if * this is a WM_MOUSEMOVE) (ID_TIMERLEAVE remains running). If we've * left the tool and entered another one then hide the tip and start * ID_TIMERSHOW with time ReshowTime and kill ID_TIMERLEAVE. If we're * outside all tools hide the tip and kill ID_TIMERLEAVE. On Relayed * mouse button messages hide the tip but leave ID_TIMERLEAVE running, * this again will let us keep track of when the cursor leaves the * tool. * * * infoPtr->nTool is the tool the mouse was on on the last relayed MM * or timer expiry or -1 if the mouse was not on a tool. * * infoPtr->nCurrentTool is the tool for which the tip is currently * displaying text for or -1 if the tip is not shown. Actually this * will only ever be infoPtr-nTool or -1, so it could be changed to a * BOOL. * */ #include #include #include "windef.h" #include "winbase.h" #include "wine/unicode.h" #include "wingdi.h" #include "winuser.h" #include "winnls.h" #include "commctrl.h" #include "comctl32.h" #include "wine/debug.h" WINE_DEFAULT_DEBUG_CHANNEL(tooltips);
