Summary: Missed key presses w/ TabletPC Stylus

Initial Comment:
Version 2.81

condition exists with all roms included in dist, also 
in most recent rom updates from TI.  Appears to be 
independent of rom used.

machine is a Fujitsu Lifebook T4210 running XP Tablet 
2005 (sp2) with factory pen driver installed.

Problem:  when attempting to tap on the buttons, most 
taps fail to register.  key presses do register when 
the trackpad button is used, and also when pen is 
double tapped to produce a double click.  Note that 
key pressed DO occasionally register with the single 
pen tap, but it is around one in 20 or so.  

tried changing emu speed lock, but it did no good.

have not tried with the updated driver Wacom has on 
their website.  

is it possible that the mouse-down event from the pen-
tap is too brief for TiEMU to catch?
just tested theory.  very rapid taps on the track pad 
button are also missed by TiEmu, though windows 
itself does catch them (was able to do a sharp tap to 
change window focus, but the same tap would not 
register a key press. tested several times to verify.

Or it might be this one:
http://bugzilla.gnome.org/show_bug.cgi?id=143460
which has been fixed on January 19 in the GTK+ 2.10 branch. Unfortunately,
the latest GTK+ from gladewin32.sf.net is a 2.10.7 dated January 9, thus
we'll have to wait for the next version to see if that helped.

However, all 3 upstream bugs might be different problems, because they all
affect the Wintab API, which (as far as I can tell) is not used by default,
not the regular mouse API.

Actually, it's more likely to be this one:

Could this be related to this GTK+ bug?
http://bugzilla.gnome.org/show_bug.cgi?id=154657

In any case, I suspect the problem to be in GTK+, not TiEmu, though I
could be wrong.

Romain, you said in #1634831 that you can't fix this. Is there really no
way we can solve this problem? We already got 3 reports of tablet-related
problems (this bug and 2 duplicates).

Perhaps because Windows sends a "click" event when clicks
are registered by Windows (because Windows also registers
clicks when the tablet pen is tapped and moved slightly, or
if the touchpad is tapped lightly), but TiEmu registers by
mouse down/mouse up, which might not always work under these
conditions, and besides, it wouldn't account for special
conditions like the ones that Windows handles for tablet PC
clicks.

This is just my hypothesis: perhaps the GTK version of TiEmu
uses image areas for the buttons and registers mouse down/up
events, instead of button widgets, which probably would
register mouse clicks correctly.

just a note: VTi 2.5 b5 does not display this problem.

UPDATE:  key presses ARE recognized if the stylus is 
draged across the key.  Tap and hold, key press is not 
recognized, but then drag a little, and the key press 
registers.
