/* Cannot use TrackMouseEvent, as the stupid WM_MOUSELEAVE message
|

* doesn’t tell us where the mouse has gone. Thus we cannot use it to
|
||
* generate a correct GdkNotifyType. Pity, as using TrackMouseEvent
|
||
* otherwise would make it possible to reliably generate
|
||
* GDK_LEAVE_NOTIFY events, which would help get rid of those pesky
|
||
* tooltips sometimes popping up in the wrong place.
|
||
*
|
||
* Update: a combination of TrackMouseEvent, GetCursorPos and
|
||
* GetWindowPos can and is actually used to get rid of those
|
||
* pesky tooltips. It should be possible to use this for the
|
||
* whole ENTER/LEAVE NOTIFY handling but some platforms may
|
||
* not have TrackMouseEvent at all (?) --hb
