Jay:
 
I tried "set USE_EVENT_WM_CHAR=1"
 
The result is that I get two or more characters on the screen for each
single character typed.
 
Regards,
Randy

Try this also:
 
d:\dev2\cm3.2\m3-ui\ui\src\winvbt\WinTrestle.m3
 
(*--------------------------------------------------------
initialization ---*)
VAR
  useEvent_WM_CHAR := FALSE;
BEGIN
  WITH v = Env.Get("USE_EVENT_WM_CHAR") DO
    IF v # NIL THEN
      useEvent_WM_CHAR := Text.Length(v) = 0 OR
                          Text.GetChar(v, 0) = '1' OR
                          Text.GetChar(v, 0) = 'y' OR
                          Text.GetChar(v, 0) = 'Y';
    END;
  END;
  CreateTrestle ();
END WinTrestle.


 set USE_EVENT_WM_CHAR=1
 or 
 set USE_EVENT_WM_CHAR=Yucky! 
 
(I think it should check for "y", or "yes", case insensitive, not just
any string that starts with "y".., or only allow 0 or 1, and error for
anything else, and put M3 or CM3 at the front of the variable to not
clash with other uses...)
 
Though, granted, I am just totally guessing right now.

Hi all:
They are @M3TraceWinMsgs and @M3SlowTrace
I get it in the file m3-ui/ui/src/winvbt/WinTrestle.m3
lines 1096, 1097
  trace_msgs := RTParams.IsPresent ("TraceWinMsgs");
  slow_trace := RTParams.IsPresent ("SlowTrace");
Thanks

Hi all:
I think I remember somewhere there are runtime parameters for debugging
Trestle
on windows implementation. Check the source code of it; I can't find
them in
this moment.
Thanks

Rodney:
 
I am using Windows XP Professional, Service Pack 2 (on some systems,
Service
Pack 3 is applied).
 
Michel Dagenais suggested that if the problem does not reproduce on
Linux, that
it might have to do with how Windows reports character events.  He
thought a
Filter VBT may exist somewhere that would aid in debugging by printing
method
calls before propagating them to father/son.  This filter VBT would be
inserted
at different places in the VBT tree to get tracing information.  Are
you
familiar with something like this?
 
As for the pixmaps, Michel suggests increasing the resolution of the
original
pixmap to help alleviate problems with upscaling.  I may try this, but
of
course, FormsVBT uses a lot of pixmap resources, for example, radio,
boolean,
checkmark, numeric, etc all use pixmaps.
 
Regards,
Randy

Which variant of the M3 Windows target are you using?  I don't have
any
of them built right now.
