Bug 446466

It didn't happen in my system, and I did an anaconda upgrade.

For example,
/usr/share/applications/kde/colors.desktop
/usr/share/applications/kde/fonts.desktop
include
Hidden=true;

But, these *do* get hidden with
Hidden=true
(sans ;)

I'll have to go check the spec to see if it covers the ;

Ugh, looks like ; shouldn't be there:

http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-1.0.html

"Some keys can have multiple values. In such a case, the value of the key is
specified as a plural: for example, string(s). The multiple values should be
separated by a semicolon. Those keys which have several values should have a
semicolon as the trailing character. Semicolons in these values need to be
escaped using \;."

OK, found it, 
kdebase3.spec:
perl -pi -e "s,OnlyShowIn=KDE,Hidden=true," *

kdebase3-3.5.9-11.fc9 has been submitted as an update for Fedora 9

update revoked, turns out
Hidden=true
breaks kcmshell.  Kevin's looking into it.

imo it doesn't make sense to show the kcontrol modules in other desktops. We 
just let the default upstream setting in desktop files. 

In particular, we don't even want to see any kde3 kcontrol modules on KDE4
desktop either.

One reason why I had a quick braindump to support something like
OnlyShowIn=KDE3

The point of using Hidden=True rather than OnlyShowIn=KDE is that we don't want 
these things to show up in the KDE 4 menus either.

Rex, can you try NoDisplay=True instead of Hidden=True? Hidden essentially 
means this is deleted entirely, which is probably why it breaks kcmshell. 
NoDisplay is what should be used to hide things:
http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-1.0.html#recognized-keys

it's correct, NoDisplay=true should work. it's what we need.

NoDisplay=true is better, but still doesn't work right.
$ kcmshell proxy
shows a window now, except it is blank.

Argh, I'll try to fix the code. NoDisplay=true should be the right thing to 
use.

kdelibs-3.5.9-kcmultidialog-ignore-nodisplay.patch

Can you please try this (trivial) kdelibs3 patch?

Another thing worth trying would be if OnlyShowIn=KDE3 doesn't actually do the 
right thing there. Or even OnlyShowIn=asdfgh for that matter. ;-)

bad news: patch doesn't work, nor does OnlyShowIn=KDE3
both (still) result in a blank window.

Another try.

OnlyShowIn=KDE3 support for KService, KServiceGroup

> One reason why I had a quick braindump to support something like

This patch adds that to KService and KServiceGroup. (For future reference:
OnlyShowIn is also used in kdelibs/autostart, kdebase/kdesktop and
kdebase/libkonq, if we want full support for this feature, those are the places
to patch too.)
