showOperatorDialog
public void showOperatorDialog()
- In this function implementations should handle displaying the
OperatorImpl.operatorDialog
via its show() method. Also any input parameters should if instantiated be loaded
into the dialog prior to it being displayed. These should then be dislpayed after
it is complete. NB this is modal dialog so once the show method is called
execution will block. After the call the parameters can be got via
OperatorDialog.getParameter(java.lang.String)
.
