Hi Kostya,

 

What you are asking to do is quite possible.  In fact, I needed to do something similar in the product that I am working on.

 

The IWorkbenchWindowActionDelegate interface is not quite enough to do this.  In addition, it is important that the action delegate also implement the IActionDelegate2 interface.  The IActionDelegate2 interface provides a way for the action delegate to be informed of the proxy action when the Add-in that provides the action is loaded.  This is done via the following IActionDelegate2 method:

 

public void init(IAction action);

 

The IAction that is passed into this method is the proxy action for this action delegate.  You can enable/disable the action using the proxy action as needed.

 

You may want to manage this from the Add-in.

 

Hope this helps!

 

Aaron

Subject: [platform-ui-dev] How can i change enable/disable state of actions defined by "Acti onSet" extension?

Hello All!

I met a problem with actions enablement!

I have several actions which are grouped into "action set" by coresponding extension in plugin.xml. Logically this actions don't relate to any view or editor, they correspond to my own self-defined perspective.These actions are appeared in Main menu and work fine ("run" methods leads to expected results). But i cann't find a way to control enablement of these actions, because i implement IWorkbenchWindowActionDelegatenot not Action directly.

I tried to use special <enablement> element of "action" extenstion with <systemProperty> condition but don't get necessary behavoir.  Enablement was changed only if SelectionChanged event occured in some View o Editor Part. But such behavoir do not cover situation when execution of one action affect on enable state of other action.

Problem may be simplified to the following situation:
i want to have 2 actions which can change enblement of each other. In other words when i click into one button on main tool bar, another button become disable and vice versa.

Could you help me solve my problem?
