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 TImageEnView controls on a form (Default: False) |
Note:
◼You can set MsgLanguage to localize the actions◼Some actions include shortcuts. The VCL does not allow these to be cleared at design-time. Disable them at run-time as follows: ImageEnView1PromptToOpen1.ShortCut := 0;
◼See the list of the default ImageIndexes if you are planning to add graphics to your actions
◼You can respond to action behavior using OnActionExecute
