Forms have two focus events with which you can use a focus trigger. The following table explains each focus event, and the corresponding value of the focus_type parameter required in the Trigger_RegisterFocus() function:

|
Focus event |
Description |
Value of focus_type |
|---|---|---|
|
pre |
Occurs each time the form opens, not each time the form restarts. |
TRIGGER_FOCUS_PRE |
|
post |
Occurs each time the form closes. |
TRIGGER_FOCUS_POST |
This trigger is activated when the Customer Maintenance form closes and the form’s post script runs (indicated by TRIGGER_FOCUS_POST).
{Name: Startup}
local integer l_result;
l_result = Trigger_RegisterFocus(anonymous(form RM_Customer_Maintenance), TRIGGER_FOCUS_POST, TRIGGER_AFTER_ORIGINAL, script IG_Close_Contact_History);
if l_result <> SY_NOERR then
warning "Trigger registration failed.";
end if;
This trigger processing procedure for the form focus trigger simply closes the third-party form.
{Name: IG_Close_Contact_History}
close form IG_Contact_History;
