Hi,

I want to enable/disable toolbar action using action.setEnabled()
method.But SelectionChanged() is only called at eclipse startup. And
afterwards , this method is not called.Hence, the button never gets
disabled.

public void SelectionChanged(IAction action, ISelection selection){

if(count%2 ==0)
action.setEnabled(true);
else
action.setEnabled(false);

}

Thanks,
Sana.

Sana,

You extended BaseSelectionListenerAction and specialized
updateSelection? (You could use action.setEnabled(count%2 ==0) for more
compact code.)

Sana,

Eclipse is full of source code that you can look at to see how others
have implemented something similar to what you're trying to do. Take
advantage of the ability to search the Eclipse site for information
related to what you're interested in...
