disable "Show All Wizards" check box when using activities [message #332938]

Hello,

Is there a way in Eclipse 3.4.1 to remove the "Show All Wizards" check
box when hiding new wizards with activities? I have some plugin
contributions that I don't want the user to make them appear in my
application.

Thanks,

Mircea

Normal activities will always show that checkbox (as they're designed to
unclutter the interface until the user wants more). In 3.4 there are
expression based activities that will remove the wizard completely and
don't add the "Show All Wizards" checkbox.

I'm impressed, although I wonder concerning the nomenclature of
"expression-based activities". AFAIK "classic" expressions already
allow (regular) expressions to restrict them. If I read your
intention correctly, it seems that the core command expressions
can be used to control activities - is that right? And they are
available as of Eclipse 3.4?

It would be very nice, if you could give us a pointer to an
example which shows these extended use-cases of activities
combined with core expressions.

Thanks in advance,

Daniel Krügler

Yes, available in 3.4. The examples that we have is a small entry in
the help at
http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.platform.doc.isv/guide/workbench_advext_activities.htm
plus an implementation in org.eclipse.ui.examples.contributions in CVS.

They were added under bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=201052

Later,

Thanks Paul, for this IMO quite important and powerful
extension of activities! We considered using activities in
our original RCP design but withdraw them because of just
this (for us) unwanted effect, that any user can auto-promote
to a some kind of "super-user" and thus can circumvent
a programmer-intended barrier - just the issue the OP
mentioned!

I wonder why this new feature had not been emphasized more
strongly in the release readme? - it really would have been
worth it!

It's an added enhancement, but activities are about UI simplification
and progressive disclosure to advanced users and are not really more
than a cosmetic security feature :-)

The expression based activities 1) remove items more completely (which
is why you can't get them back with a show all) and 2) don't allow the
user to modify them (their state is entirely based on the expression,
not anything else).

There is some good work at the equinox level to do with security, but I
haven't seen a good story for propagating it up to the UI
