CursorStyle top_edge|bottom_edge|left_edge|right_edge not working

[dumblob]

Upfront Information

• Fvwm3 version (run: fvwm3 --version):

fvwm3 1.0.7 (1.0.6a-12-gd61963f2)
with support for:  ReadLine, XPM, PNG, SVG, Shape, XShm, SM, Bidi text, XRandR, XRender, XCursor, XFT, NLS

• Linux distribution or BSD name/version: Arch Linux (Linux 6.1.21-1-lts # 1 SMP PREEMPT_DYNAMIC x86_64)

• Platform (run: uname -sp): Linux unknown

Expected Behaviour

What were you trying to do?

I have put into the default config:

CursorStyle top_left     crosshair
CursorStyle top_right    crosshair
CursorStyle bottom_left  crosshair
CursorStyle bottom_right crosshair

CursorStyle top_edge     crosshair
CursorStyle bottom_edge  crosshair
CursorStyle right_edge   crosshair
CursorStyle left_edge    crosshair

And expected the mouse cursor to change to crosshair everywhere.

Actual Behaviour

Only the corner (i.e. the first 4 lines) cursor styles got applied. The edge cursor styles stayed at their defaults 😢.

Enabling logging

There is nothing additional in $HOME/.fvwm/fvwm3-output.log compared to when started wihout those 8 lines above.

Steps to Reproduce

How can the problem be reproduced? For this, the following is helpful:

• Reduce the problem to the smallest fvwm configuration example (where
  possible). Start with a blank config file (fvwm3 -f/dev/null) and go from
  there.

See above how to adjust the default distributed config.

• Does the problem also happen with Fvwm2?

I did not try this (I do not have FVWM 2 installed any more).

Does Fvwm3 crash?

No crashing.

Extra Information

N/A

Do you have the mentioned commands in your config file as shown there with all those spaces?
CursorStyle top_edge crosshair it does not work, but CursorStyle top_edge crosshair does work as expected. I would suggest removing all those unnecessary spaces and trying again.

[dumblob]

Cood idea - have tried it now but no luck (it still shows the default cursors instead of crosshair):

CursorStyle top_edge crosshair
CursorStyle bottom_edge crosshair
CursorStyle right_edge crosshair
CursorStyle left_edge crosshair

[lgsobalvarro]

It could be that the Cursor theme you are using does not include crosshair. I have experienced similar things before. Some cursor themes do not include all known/regular cursor names. For instance for crosshair there is a tcross, cross and even cell. However... even if the cursor theme does not include a crosshair, fvwm should use a generic one.

I can't reproduce the problem using the provided your CursorStyle (once removed the unneeded spaces).

[dumblob]

My cursor theme certainly contains the crosshair cursor as I am happily using it for

CursorStyle top_left     crosshair
CursorStyle top_right    crosshair
CursorStyle bottom_left  crosshair
CursorStyle bottom_right crosshair

cursorstyles as noted in the original post 😉.

Yet I find it really fishy (read wrong) that in your setup there is a different behavior with multiple spaces in between the command arguments and with a single space.

Hi @dumblob

Sorry for the delay. Please have a look at the ta/gh-851 branch which should fix this issue.

Thank you @ThomasAdam !
