I have tried this, but this way i can see my action in popup menu when i
click on file in package explorer. But i still cant use it on selected text.
I should be able to select any text in the editor and then execute my
action. Thanks for your help, but it seems i am not able to do it.
I tried setting objectClass to java.lang.Object and then action works this
way: I select file in the explorer left of the editor, then open it. When i
select some text in the editor, selectionChanged doesnt occur to this
selection, but selection remains opened file. I tried

/**
  * @see IActionDelegate#selectionChanged(IAction, ISelection)
  */
 public void selectionChanged(IAction action, ISelection selection) {
  currentSelection = selection;
 }

and currentSelection is IFile. When i do
((StructuredSelection)currentSelection).toString() i get /temp/test.txt
instead of my text selection.
Are there sources for PDE extenstions and their standard editor?

Thanks,
Radovan
