TabTriggerEvent – PB Docs 2019

tabcontrolname

The name of the Tab control for which you want to trigger
events for its tab page user objects.

event

A value of the TrigEvent enumerated datatype that
identifies a PowerBuilder event (for example, Clicked!,
Modified!, or DoubleClicked!) or a string whose value is the
name of an event. The event must be a valid event for a tab page
user object in tabcontrolname and a script must exist for the
event in tabcontrolname.

word (optional)

A long value to be stored in the WordParm property of the
system’s Message object. If you want to specify a value for
long, but not word, enter 0. (For cross-platform compatibility,
WordParm and LongParm are both longs).

long (optional)

A long value or a string that you want to store in the
LongParm property of the system’s Message object. When you
specify a string, a pointer to the string is stored in the
LongParm property, which you can access with the String function
(see Usage for TriggerEvent).
