[news.eclipse.tools] Re: MultpageEditor Accelerator problem

Hi Ron,

I run into quite the same problem earlier this week. I don't know if the
described behaviour is a bug or if it is intended and we just do not
understand how to handle it correctly. Whatsoever, I finally implemented
the following work-around:

private void setCopyPasteBinding(boolean routeToEditor) {
  IKeyBindingService bind = getEditorSite().getKeyBindingService();
  if (!routeToEditor) {

    // Stop actions from being sent to the embedded text editor.
    bind.unregisterAction(
      editor.getAction(ITextEditorActionConstants.CUT));
    bind.unregisterAction(
      editor.getAction(ITextEditorActionConstants.COPY));
    bind.unregisterAction(
      editor.getAction(ITextEditorActionConstants.PASTE));
    bind.unregisterAction(
      editor.getAction(ITextEditorActionConstants.SELECT_ALL));
    bind.unregisterAction(
      editor.getAction(ITextEditorActionConstants.DELETE));
  } else {
    // Reconnect actions with text editor on page 0.
    bind.registerAction(
      editor.getAction(ITextEditorActionConstants.CUT));
    bind.registerAction(
      editor.getAction(ITextEditorActionConstants.COPY));
    bind.registerAction(
      editor.getAction(ITextEditorActionConstants.PASTE));
    bind.registerAction(
      editor.getAction(ITextEditorActionConstants.SELECT_ALL));
    bind.registerAction(
      editor.getAction(ITextEditorActionConstants.DELETE));
  }

  // Propagate changes.
  getActionBars().updateActionBars();
}

Call this whenever the displayed page changes, and COPY/PASTE should work
again. At least for me it does..

Good luck,

Tobias
