Hi!

I would like to know how to disable lets say an
erase action on an selection where this action shouldnt
be possible. In short how to turn an action in an context
menu to gray.

Regards

You can update the IAction on selection change within your action delegate.

Or, depending on the extension, you can add an <enabledment/> element to
each action. Check out the extension point description that you are
using (I assume it's org.eclipse.ui.popupMenus)

I solved it .... the Action class has a method called setEnabled(boolean) ,
set as false and voila it disabled.
I tryed to solve this some time ago and really readed the hole API for
Action and didnt seen this method.
Thank you for the fast answer.

Regards.
