I am programming against Eclipse 2.0.2 (since the products I am targeting still
use Eclipse 2.0.2).
I am trying to add some semi-dynamic menu support, by extending the "Project"
menu with a RetargetAction that I programmatically will link to the right action
as the state of the plugin changes.
I am building a plugin that desires to use a LabelRetargetAction. I cannot seem
to get the action to work, and I cannot find an example of the right linkage.
One of my questions deals with the interplay between plugin.xml stanzas and my
code. I have an action definition, and I have an actionset. The actionset has
a single retarget action, so I do not specify a class.
In my code, I register as a WindowListener, and in the windowActivated method I
attempt to add the action to the partService as shown in the code snippet below
labeled "ADD ACTION".
However, my entry on the Project menu stays grayed out. It also has the label
from the plugin.xml, not from my resource string as defined in the add action code.
Something is missing, but I cannot find an example of how to do this.
A second question deals with global key bindings, and how to hook up to them.
It appears that global key bindings are not available for public access in
2.0.2, since it seems that I have to cast my IWorkbenchWindow to something much
more heinous in order to get access to a KeyService.
Help!
