System Events
InstantView® knows the following predefined events:
| Event | Description |

| ENTER | The Enter key was pressed in an input field. (see SELECT) |
| CURRENT | the window object receives the focus (also when opening a window)
|
| NON_CURRENT | the window object returns the focus (also when closing a window) the module is no longer the active module Attention: Is not triggered in the module if the processing of the last message is cancelled with an error message. |

| CLOSING | The user has pressed the X of the window, or (ALT+F4) and wants to close the window Closing can be prevented by returning a FALSE with ReturnStack in response to the message. Alternatively, closing can be prevented by pressing cancel. If the message is not handled, or if there is another result on the stack, the window is closed. |
| INITIALIZE | Triggered on any Window object during OpenWindow. Attention: Is triggered on the STARTUP window before the INITIALIZE of the associated module! |

| IS_DROPPABLE | an object is dragged and dropped, the potential source and target objects and the insert mode are on the stack The return value (0 or 1) determines whether a drop is allowed. |
