GML::LUM_EVENT - Determine Look-up Control Focus Status

Syntax

CALL "GML::LUM_EVENT"

Description

This procedure determines if a look-up control has lost focus; hides the control as required. It is executed when the value of variable GML.LUM_FLAG% is not equal to 0, and an event other than a list control or mouse event (code = m) has occurred. The event ID is placed in GML_LUM.EVENT_ID% and the event context is placed in GML_LUM.EVENT_CONTEXT% variable. The Look-Up Manager is then called by executing a call to the GML to determine if the look-up control has lost focus, and hide the control as required.

Example

2400 GML_LUM.EVENT_ID%=EVENT.ID%            
2410 GML_LUM.EVENT_CONTEXT%=EVENT.CONTEXT%   
2420 CALL "GML::LUM_EVENT"
