      Override this method if additional enabled states must be processed.

    • setInput

      protected boolean setInput(String input)
      Updates the entry or visible part in the editor with a new property value that is not in error state. The default implementation updates the combo box or text with the value.toString() representation. The existing input should be checked for difference in order not to update the entry if not required. If the input is null, it means no change of the current input the user has made or was previously set.
      Returns:
      true if changed, false for no change.

    • setInputValueFromProp

      protected void setInputValueFromProp(PROP_VALUE value)
      Sets the input value from an update of the property value. If the input is null, it means the same as setting an empty value.

      The default is to call doValueChangeConversion() and if it returns true, the value is retrieved using getCurrentValue() with try-catch, and if the returned value is the same as the value passed into this method, nothing is performed. Otherwise setInputValue(Object) is called.

      Parameters:
      value - The value to set, null for empty.
    • setInputValue

      protected void setInputValue(PROP_VALUE value)
      Sets the input value when editing, when formatting the value from a string. If the input is null, it means the same as setting an empty value.
