Base Properties
  ActionType Specifies the type of action: whether the control only performs a function (ieaButton), toggles a state (ieaCheckbox), or changes between multiple states (ieaRadioButton)
  ImageEnView Optional property: Specify a TImageEnView if you have multiple on a form and want to limit actions to one of them
  RequiresFocus If enabled, actions have no effect unless a TImageEnView is focused, otherwise actions work and change whatever control is focused. You must set this to true, or use the ImageEnView property if you have multiple TImageEnViews on a form (Default: False)



Notes:


- You can set MsgLanguage to localize the actions
- See the list of the default ImageIndexes if you are planning to add graphics to your actions
