Is _WHEEL not working? - TerryRitchie - 04-17-2023
In the wiki under _WHEEL the following example code is given. If I'm understanding this correctly when you issue the command:
ignore = _MOUSEMOVEMENTX
this is supposed to put the mouse into a relative movement mode allowing _WHEEL(1) and _WHEEL(2) to read the mouse x,y movements. However, no matter what I try I can't seem to get this working? Any suggestions? I went back as far as version 0.8.2 and it doesn't work there either.
Code: (Select All)
ignore = _MOUSEMOVEMENTX 'dummy call to put mouse into relative movement mode
PRINT "Move your mouse and/or your mouse wheel (ESC to exit)"
d = _DEVICES ' always read number of devices to enable device input
DO: _LIMIT 30 'main loop
DO WHILE _DEVICEINPUT(2) 'loop only runs during a device 2 mouse event
PRINT _WHEEL(1), _WHEEL(2), _WHEEL(3)
LOOP

hello TerryRitchie
the third column seems to work for me, if I roll toward the monitor I get -1, roll toward me I get 1
the first 2 columns remain 0

Correct, _WHEEL(3) works fine but I can never get _WHEEL(1) or _WHEEL(2) to work. I've tried putting ignore = _MOUSEMOVEMENTX inside the loop as well but nothing. I also tried _MOUSEMOVEMENTY but still nothing.

My mouse only has 1 wheel and it registers as Wheel(3) on your code.
Yet the code counts 3 Wheels so what, are wheel(1) and wheel(2) are x, y axis wheels?

Yes, according to wiki when mouse is in relative mode.

As I recall _MouseMovement never did work or work correctly. It might have been worked on after v2.0 though.

_MOUSEMOVEMENTX and _MOUSEMOVEMENTY did work at one time long, long ago. I write an iOS desktop clone that relied on those two statements to move icons from one place to another after a click-and-hold was performed on them. I'll need to dig that code out and see if it works in the latest versions of QB64.
RE: Is _WHEEL not working? - TempodiBasic - 04-19-2023
Hi Terry
running the code on #1 on my Lenovo Ideapad con touchpad
I have no wheel in hardware, but using touchpad if I do "the two fingers" movement used to scrolling pages I get -1/1 (as _wheel works) on the third column.
I hope this feedback is useful
RE: Is _WHEEL not working? - TerryRitchie - 04-20-2023
I found that code I referenced earlier. The _MOUSEMOVEMENTX and _MOUSEMOVEMENTY statements are in line 235. I wrote this in QB64 v0.954 back in 2012 and it works fine in that version. However, any version 1.3 and higher the commands act strange and don't sync with the movements of the mouse.
So I can confirm these two statements are not working as intended now. The attached zip file contains the code and icon images if you want to try it for yourself.

Hello TerryRitchie
I can click and drag the icons but the mouse pointer moves faster than the icon being dragged, it does not stay on the icon but moves further and further away from the icon as you move it
