Mouse cursor jumps

Terrance_Huang · August 9, 2022, 5:26am

When doing any operation, drag, move, duplicate, add symbol… , mouse cursor jumps to another location. seemingly some where upper left.

This does not happen if I only use cursor keys.

how to disable this “feature”?

Probably "Center and Warp Cursor on Zoom.

Preferences / preferences / Mouse and Touchpad.

The:

… function should put the cursor in the center of the screen. It did take me some time to get used to it, but now I’m wishing for other programs to also have this ability.

The “Center and Warp Cursor on Zoom” also only activates on zooming (Which I usually activate with the scroll wheel), and not:

I’m guessing it may be some kind of bug

Terrance_Huang · August 12, 2022, 7:12am

Thanks, but none of items in settings work.

Generally a program SHOULD NOT manipulate OS’ cursor location, it could be very annoying and unpredictable. or, at least, give us an options to turn it off.

Terrance_Huang · August 12, 2022, 9:16am

Another scenario. if Schematic Editor window is not maximized.

place a text
type text
use mouse to place text

then KiCAD moves mouse cursor to top left corner of entire screen, out side of sch window, then trapped there.

eelik · August 12, 2022, 9:37am

That’s definitely some kind of bug or other problem somewhere (not necessarily in KiCad!), KiCad doesn’t behave that way.

Terrance_Huang · August 12, 2022, 9:42am

please test it before “doesn’t behave that way.”

Thanks!

but, if “Center and Warp Cursor on Zoom.” is on, zoom snaps the cursor to a point, I check with screenshot and GIMP, x:460, y:252.

Seemingly some where it got the resolution/windowsize wrong.

eelik · August 12, 2022, 10:43am

I know pretty well how KiCad behaves in this respect. It moves the mouse cursor in some situations, but not when

As I said, if this happens, it’s definitely a bug or some other problem, not how KiCad normally behaves or should behave, regardless of any settings. I just tested, it works OK, so this may have something to do with your system or some sw combination.

Terrance_Huang · August 12, 2022, 10:47am

I commented out most ->WarpPointer and building from source.

Terrance_Huang · August 12, 2022, 10:47am

if you use MacOS, ->WarpPointer() doesn’t work at all, no work, no bug.

Terrance_Huang · August 12, 2022, 10:59am

It works! Disable all ->WarpPointer and build it. works perfectly fine like good old KiCAD. Thank you guys!

eelik · August 12, 2022, 12:33pm

I don’t use MacOS, I use – well, currently only test regularly – KiCad on Linux and Windows. There’s no such bug there. You should probably report it with detailed information about the use case and exact steps to reproduce it. Even better if you could track it down yourself because you apparently can read and edit the code. Great if commenting out code works for you, but it doesn’t help other users or the developers. The latter need more information to fix it if it works for them on MacOS.

Terrance_Huang · August 12, 2022, 5:18pm

sure, in the past KiCAD 3, 4, 5 all works fine, no this kind of issue.

currently it’s really messy and might be

debian’s package
6.0.6 / 6.0.7?
buggy wxWidgets
many other

Also I didn’t even try building from original 6.0.7 src.

kind of in the middle of a large project, have not much time to get this pinned down. just need some quick & dirty walk around for me to finish that first, then dig deeper.

thanks!

btw, which DE do you guys test on Linux?

Terrance_Huang · August 13, 2022, 1:09am

only one needs to be commented out.

in common/view/wx_view_controls.cpp

void WX_VIEW_CONTROLS::WarpCursor(...
    ...
    // m_parentPanel->WarpPointer( screenPos.x, screenPos.y );
    ...

does this warp cursor to its current position??
