Showing actions in PopupMenu only in special cases [message #631491]

Hi,

I want to add some entries to the context menu on the IResources that are shown in the Package Explorer.

Therefore I used the extension point "org.eclipse.ui.popupMenus". The first subelement is of the type objectContribution.
The difficult part is now that some entries should be shown only in special cases. Therefor I need to check the state the selected file and with checking the state I mean, that I need to read out a configuration file and to determine if the IResources was enabled for that Action.

How can I reach this goal?
Thank you.

You can implement an IActionFilter for your specific IResources and
use the filter attribute in your objectContribution. To make this work,
you will probably need to make these resources adaptable to the specific
filter, e.g. via an IAdapterFactory using the
org.eclipse.core.runtime.adapters extension point.

You can also use org.eclipse.ui.menus/menuContributions and
commands/handlers. The visibleWhen for a command element is much more
flexible than what comes with objectContributions.

Thank you Daniel Krügler and Paul Webster.
I used now a menuContributor and "org.eclipse.core.expressions.propertyTesters". That was the best solution for my need.

Your hints brought me directly to a good solution.
Cheers Adrian and greetings from Stuttgart.
