Can you elaborate on under which conditions you would want to automatically click "OK"? In JSL, you can programatically click a button using something like "OK_button << click;"
If, for example, you want to programatically click OK once all required inputs are populated, you could write a function or expression like this:
check_inputs = Expr(
If(
N Items( y_inputs << get items ) > 0 & N Items( x_inputs << get items ) > 0
& N Items( parts_inputs << get items ) > 0,
OK_button << click
)
);
Then, within the script for each of the input buttons, you could add check_inputs() at the end.
