Re: Mouse wheel is now supported in vDos-lfn

[Harry Binswanger hb@xxxxxxxx]

Wengier,

It's no doubt not worth the bother. But for the record, XyWrite reports the
scancode of Ctrl-w as 2065. That's from the U2's SCAN frame. Or are you
saying that that embodies the flag?


Regards,
Harry



Hi Harry,

I think it will become very complicated if I allow for such movements. For
example, you might even want the cursor to move up, right and up, right
again, and doing this can be quite difficult to be implemented. Also, if
you only have one mouse wheel, how can it handle such complicated tasks?


A single keyboard message consists of the scancode, unicode and various
flags. The Ctrl state is part of a flag within the keyboard message. When
the scancode and various flags are combined, the system will uniquely
identify the key pressed, so the scancode alone cannot uniquely identify
the keys. For example, W and Ctrl+W have the same scancode, but their
flags will be different, so the system will be able to tell about the
difference between these key presses. Furthermore, Ctrl-W/Z is intended
for programs like WordStar and DOS EDIT, not XyWrite, so you probably want
to use a different setting for WHEELMOD instead (but admittedly, Ctrl-W
should not output plain W in XyWrite either; I am wondering what causes
this on your system, as this never happens during my testings).

Wengier,

Do you mean two separate wheels? No, I've never seen that. By 2-D mouse
control, I'm talking about being able to use the mouse to move the cursor
up and down AND right and left.

If the Ctrl state is not part of the scan codes, in what sense is it
outputting ctrl-w rather than just w? (And, in fact, plain w is what I get
as output to XyWrite.)

Harry
