Dollyn,

Here's an example where it's used in selectionChanged:

�0„2 public void selectionChanged(IAction action, ISelection selection)
�0„2 {
�0„2�0„2�0„2 if (selection instanceof IStructuredSelection)
�0„2�0„2�0„2 {
�0„2�0„2�0„2�0„2�0„2 Object object = ((IStructuredSelection)selection).getFirstElement();
�0„2�0„2�0„2�0„2�0„2 if (object instanceof GenModel)
�0„2�0„2�0„2�0„2�0„2 {
�0„2�0„2�0„2�0„2�0„2�0„2�0„2 genModel = (GenModel)object;

�0„2�0„2�0„2�0„2�0„2�0„2�0„2 action.setEnabled(true);
�0„2�0„2�0„2�0„2�0„2�0„2�0„2 return;
�0„2�0„2�0„2�0„2�0„2 }
�0„2�0„2�0„2 }
�0„2�0„2�0„2 genModel = null;
�0„2�0„2�0„2 action.setEnabled(false);
�0„2 }

Maybe in run you'd look astisChecked to behave one of two ways or you'd toggle that state...

There are two methods in this interface : SelectionChanged(IAction action, ISelection selection) and run(IAction action).
Who can tell me what is the "IAction action" used for? I've looked at some examples, but didn't find anyting about this parameter.
