FORM Event returns an object containing information about the form event that has just occurred. Usually, you will use FORM Event from within a form or object method.
Returned object
Each returned object includes the following main properties:
| Property | Type | Description |
| objectName | text | Name of the object triggering the event - Not included if the event is triggered by the form |
| code | longint | Numeric value of the form event. See Form event code |
| description | text | Name of the form event (e.g. "On After Edit"). |
For example, in the case of a click on a button, the object contains the following properties:
{
"code":4,
"description":"On Clicked",
"objectName":"Button2"
}The event object can contain additional properties, depending on the object for which the event occurs. For example, eventObj objects generated on 4D View Pro areas return additional properties, such as row, column, or sheetArea (cf. 4D View Pro form events).
Note: If there is no current event, FORM Event returns a null object.
You want to handle the On Clicked event on a button:
If(FORM Event.code=On Clicked)
...
End if
