How do I determine what text the user has highlighted when they click on a
button I added to the toolbar? I really only care about the java editor.
Thanks

Thanks for your reply. I believe I want the second option. So, if the run
method is being called when the button is pushed, how do I get the current
editor and see what type it is. I have a lot of java experience, but no
eclipse experience, so you can be tech. in your reply.
Thanks
public class SampleAction implements IWorkbenchWindowActionDelegate {
private IWorkbenchWindow window;
public SampleAction() {
}
public void run(IAction action) {
}
}

Here is an excerpt from something I wrote:
public class CompletionAction implements IWorkbenchWindowActionDelegate {
/** The window where the action appears */
private IWorkbenchWindow activeWindow = null;
public void init(IWorkbenchWindow window) {
activeWindow = window;
}
/**
* Run the action. First check whether we can continue
* the previous completion operation. If not,
* create new completion operation and invoke it.
*/
public void run(IAction proxyAction) {
IEditorPart editor = activeWindow.getActivePage().getActiveEditor();
ITextEditor textEditor;
if (editor instanceof ITextEditor) {
textEditor = (ITextEditor)editor;
} else {
activeWindow.getShell().getDisplay().beep();
return;
}
ITextSelection sel =
((ITextSelection)textEditor.getSelectionProvider().getSelect ion());
}
}

The article "Contributing Actions to the Eclipse Workbench" on http://www.eclipse.org/articles/index.html is one of my favorites and
is a must read if you want to add any kind of action.
As an alternative to recording the selection as it changes via selectionChanged you can store the active editor set in
IEditorActionDelegate.setActiveEditor and get the selection via the editor part/editor site/selection provider when you need it.
