disable mouse scroll

[400thecat]

When I accidentally scroll mouse wheel on the panel, it switches virtual desktops.

How can I disable this before it drives me crazy ?

Seriously, whoever thought this was a good idea ?
Who switches desktops with his mouse wheel ?

And when I scroll mouse on application in the task bar, it switches between applications.

Seriously, this is evil.
Is there some way to disable this ?

[eleksir]

It's not that evil as you describe it.
Actually if you give me proper PR i'll apply it to my fork of fbpanel and tag it, so you can pull it as release (it'll be 7.3 in my case).

thanks for looking into it.

FYI: I have also posted a question on Stack Exchange for this particular problem.

If you could implement a fix, where this behavior could be turned of with a config option, that would be terrific.

BTW, I am already using a patch, also from Stack Exchange so that I can use 3 separaste instances for 3 monitors. Would you perhaps want to include that patch as well?

Reimplement `Xinerama support' patch for 7.0

Original patch from 2011:
https://sourceforge.net/p/fbpanel/patches/67

At least it looks like the only xinerama one that was found in one of the fbpanel forks.

[eleksir]

I just gather some patches for fbpanel in one place.

Here's 3 patches if it helps at all.

Hi

I tried to implement all the 3 snakejr1's patches to aanatoly's 7.0 version and to eleksir's 7.2 version - it didn't help (didn't stop the desktops to be switching with the mouse wheel).

I would appreciate much too if the option to disable this switching is added to fbpanel. I like fbpanel very much, been using it for years.

Ya sorry that was really meant for eleksir just to show the files and some examples of the code that causes the behavior. There are many more things in those three files that can cause the virtual desktop switching depending on your set up.
