Is there a form of veto on page or forms being closed or of hiding the close icon?

Hi Dominic,
sorry for the late response.

Yes, you can intercept the close event. Below, there is an example which shows a "Yes/No" dialog when the user wants to close the form. If the user selects "Yes" the form closes, if the user selects "No" the form stays open:

  @Override
  public void doClose() throws ProcessingException {
    int result = MessageBox.showYesNoMessage("Close", "Close", "Do you really want to close the form?");
    if (result == MessageBox.YES_OPTION) {
      super.doClose();
    }
    else {
      //do nothing
    }
  }

Basically, you need to override

public void doClose() throws ProcessingException

in your AbstractForm

(I wanted to attach an image, however the Eclipse Forum does not let me do so Sad

)

Hope this helps,
Best regards
Matthias
