Re: Disable "Unlock Widgets" from the panel

[Amichai Rotman <amichai@xxxxxxxxxxx>]

Why go so far?

Is there a special reason for using KDE?

For instance: Ubuntu Netbook Release comes with a locked panel (GNOME) - you can't add to it or remove from it.

These first two aren't thru kde4 itself, but here are a couple ideas:

1) If he can't properly distinguish right- and left-click (or can, but
simply doesn't have that level of motor control any more) either get him
an "Apple-style" single-button mouse or consider configuring xorg/hal to
treat the buttons the same -- as a left-click.

2) Consider changing the permissions on the files in question to read-
only. ÂPlasma will likely still let him alter the in memory running
version, but restarting plasma will then return him to an as-new config.
I'd start with $KDEHOME/share/config/plasma* and (recursively) with
$KDEHOME/share/apps/plasma*. ÂLeaving them as his ownership is likely
fine, just set them read-only. ÂOf course, you can change the ownership
(on the containing dirs too) to root or something, if desired, and ensure
he has only read perms, to really make them read-only, but that wouldn't
appear to be necessary, as from what I gather he's not doing it
deliberately.

Also, as a helpful hint, from kde 4.5, the panel setup is now scripted,
and you can create custom "default" panels if desired, so if he messes it
up, at least it's easier to rebuild -- simply choose new panel, and choose
the customized one instead of empty or the normal default. ÂIt's also
possible to clone activities, which sort of allows making a backup as
well, tho that's a bit different.

To directly answer your question, I don't see any way (which isn't the
same as saying there's not one) to directly remove that action except by
modifying source. ÂOf course, given that KDE is freedomware, that's always
an option.

Another (advanced level, and more something to do as a last resort with
servantware you don't have the sources to) workaround that could work or
help... ÂSet the panel to windows-can-cover, and create a transparent
overlay app that absorbs input you don't want to pass on, while passing on
input that you do, to the underlying panel. ÂThen use window controls to
force it to position at the correct location, go borderless, maybe always-
on-top, etc.
