    • updateControl

      public void updateControl()
      Updates control according to value in the IPrintPreferences. If it is the first update with an empty textfield, the preference value is set. If it is not the first time an empty text field occurs, nothing happens avoiding the confusing behaviour of updating to 0.00 when the user deletes all characters for preparing new input.
