see the sinppet below:
when a keyPressed event occurs to the Combo ,and then I set
the Combo.setEnable(false),but why the Selection event of
Button(returnUp) will occur at the same time ??
But if I comment path.setEnable(false),then the Selection event of
Button(returnUp) will not occur after the keyPressed event of Combo?
is it a bug?
