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

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

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).

Return Values

Integer. Returns 1 if it succeeds and
-1 if an error occurs, if the event is not a valid event for the
tab page user object, or if a script does not exist for the event.

Examples

Suppose tab_address contains
several tab pages inherited from uo_list and uo_list has
a user event called ue_display. This
statement executes immediately the script for ue_display for
each the tab pages in tab_address:
