Re: Mouse wheel is now supported in vDos-lfn



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.)

Hi Harry,

The scan codes you mentioned are generally correct (except that the scan
codes should be 72 and 80 when you set WHEELMOD=4). The Ctrl state is
*not* part of the scan codes. Rather, it comes as part of an extra flag,
and the actual scan codes are not affected by it. I am not exactly sure
what you meant by "two-dimensional mouse control". You meant like pressing
Left and Down at the same time? But I think your mouse does have both
vertical and horizontal scrolling wheels, so you should be able to achieve
this easily by scrolling both wheels about the same time. Hope this helps.

Wengier,

This is a very nice suite.

On my system:
WheelMod 4 puts out scan codes are 2 and 6
WheelMod 5 puts out scan codes 75 and 77
WheelMod 6 puts out 73 and 81
WheelMod 7 puts out17 and 44.

In other words, the Ctrl state is not coming through.

Is there any way to get two-dimensional mouse control? Like a WheelMod that
puts out different things in a shifted state?

I'm using WheelMod 2, which does a LR and LL, so it moves through the text
from line-end to next line-beginning, but that's pretty slow.

Regards,
Harry
