Earlier this week (or was it last week) I asked a question about using
the right mouse butoon and about using both mouse buttons. I got several
answers. Most of them were of the type - well, you can't do what you want
really, but here's a way to get around it. I want to thank all of these
people for there responses.
I got answers from Claus Pederson, Greg Lindahl, and George Reimer. Thank
you all for these answers. In lieu of anything else, we probably would
have chosen one of these solutions and done the best we could have. These
solutions would have worked, that was obvious.
However, I got another message from Jan Timm. I don't know what his source
is, but I have sent him (I believe Jan is a him, but he could be a her. If
I am making an incorrect assumption I apologize.) a letter requesting that
info. I am appending to this message Jan Timm's e-mail answer to my
request. It is obviously the "correct" answer. We have tested it and
it works !!! GREAT !!!
Again thanks to all who answered and special thanks to Jan Timm.

Hi,
I don't know what the problem is, but I read the following
should work: (with EVNT_BUTTON or EVNT_MULTI)
Set the parameters as follows:
bclicks mod 256 = #clicks ==> 2 for doubleclicking
if blicks div 256 == 1 then negate the following condition.
bmask : Bit0 set: check for left button according to bstate
Bit1 set: check for right button ...
bstate : Bit0 : 1 - left button pressed
0 - left button released
Bit1 : 1 - right button pressed
0 - right button released
==> e.g. wait for "not both released" = "left OR right pressed":
bclicks=267 (click) or 258 (doubleclick) /* NOT */
bmask=3 /* check left AND right */
bstate=0 /* left released, right released */
ev_bbutton lets you know which button was pressed then:
1 = left, 2 = right.
OK, maybe you knew all that, or maybe it doesn't work,
if it did help you, let me know.
Bye, Jan.
