Alexey,

Action sets don't have a visibility per se. Instead, they are associated
with a perspective. There are two ways to do this. This first is to
associate an action set with a perspective using a perspective
extension. Here's what the one for CVS looks like:

<extension
point="org.eclipse.ui.perspectiveExtensions">
<perspectiveExtension
targetID="org.eclipse.team.cvs.ui.cvsPerspective">
<actionSet
id="org.eclipse.team.cvs.ui.CVSActionSet">
</actionSet>
</perspectiveExtension>
</extension>

The other way is for the user to customize a perspective by choosing
Window>Cusomize Perspective, clicking on the Command tab and checking
off the CVS action set (or any other action set they wish to add to the
current perspective)..

i have already do it.. my question is not about visibility, i have it.. i
ask for enablement - where can i define action possibility to execute (and
represent this visuually, of course), depending by resource conditions,
for example.

For enablement, you need to adjust the result you return from
IActionDelegate#isEnabled based on the selection that is provided to
your delegate through the selectionChanged method. The internal
TeamAction class is the class that manages this for the CVS plug-in.

IActionDelegate and IWorkbenchWindowActionDelegate don't have isEnabled.
TeamAction is the best way, but it's cause "Discouraged access"-warning..
I tried to understand how TeamAction use isEnabled (where from it calling)
but can't. How it looks for me - CVS and VSS plugins have several level
wrapping actions delegate, but when isEnabled must been calling - i don't
see.

Alexey,

Sorry. I made a bit of a mistake (and shouldn't have mentioned
TeamAction since it over complicates things). The selectionChange method
on IActionDelegate is passed an IAction and an ISelection. In this call,
you should determine the enablement based on the ISelection and call
IAction#setEnabled with the appropriate value.

thank you for help, Michael!

this is my action class :

public class AddAction implements IWorkbenchWindowActionDelegate {

public void dispose() {
}
public void init(IWorkbenchWindow window) {
}
public void run(IAction action) {
}
public void selectionChanged(IAction action, ISelection selection) {
}
}
suggest me please, how implement IAction#setEnabled here?

When you delegate is instatiated, your selectionChanged(*) method will
be called. In your selectionChanged(*) method, call
action.setEnabled(true/false).

or more explicit if you implement IWorkbenchWindowActionDelegate2 there
is a dedicated method called but I can't remember which it was :-(

I add "implements IAction"
and here
public boolean isEnabled() {
return false; !!!!!!!
}
but when application running - this action is enabled!

so, i repeat my question -
how make Eclipse to use this IAction#isEnabled method?

i need a way to provide enablement for my action, please..

Show us your selectionChanged(*) method.

Put a breakpoint in it. What happens when it is called?

Don't implement IAction anywhere... it will not help you.

it doesn't metter

public void selectionChanged(IAction action, ISelection selection) {
if (selection instanceof IStructuredSelection) {
this._selection = (IStructuredSelection) selection;
}
}

It doesn't matter? ... but that was where I told you to call
action.setEnabled(false) ... you know that asking questions works better
when you also read the answers, right :-)

Paul, i read and understand, what you mean, really.
I think you (& not only you) don't understanding what i iasking here..

let's start from beginning :

in plugin.xml i define some action in org.eclipse.ui.actionSets

generating class for action must implements
org.eclipse.ui.IWorkbenchWindowActionDelegate, which don't have enablement
features, look :

public class MyAction implements IWorkbenchWindowActionDelegate {
public void dispose() {
}
public void init(IWorkbenchWindow window) {
}
public void run(IAction action) {
}
public void selectionChanged(IAction action, ISelection selection) {
}
}

what i have to do here to define my action enablement?

Ok

in
public void selectionChanged(IAction action, ISelection selection)
this action delegate my action and i can manage enablement to my action by
calling

public void selectionChanged(IAction action, ISelection selection) {
action.setEnabled(value);
}

that was what i want to know,
thanks to all!
