1- انت ممكن تنفذ الفكرة باستخدام combobox

- let u have list item of type combobox [color=blue]t[/color]
- then u have button [color=blue]b[/color]
then put this code in [color=green]WHEN-LIST-CHANGED[/color]
IF :T IS NULL
THEN 
set_item_property('b',enabled,property_false);
else
set_item_property('b',enabled,property_true);
end if;

2- انت ممكن تنفذ الفكرة باستخدام timer

- let u have text item [color=blue]t2[/color]
- let u have button [color=blue]b2[/color]
then put this code in[color=green] WHEN-NEW-FORM-INSTANCE[/color]

DECLARE
T TIMER;
BEGIN

set_item_property('b',enabled,property_false); -- initial state

set_item_property('b2',enabled,property_false); -- -- initial state

T:= CREATE_TIMER('TIMER1',100,REPEAT);
END;

put also this cod in [color=green]WHEN-TIMER-EXPIRED[/color]

if get_application_property(TIMER_NAME )= 'TIMER1'
then
 IF :T2 IS NULL
 	THEN 
 	set_item_property('b2',enabled,property_false);
 else
 	set_item_property('b2',enabled,property_true);
 end if;
end if;

وبالتوفيق ان شاء الله
