In a previous example, “Changing the Flex ComboBox control’s opening and closing easing functions”, we saw how you could control how the open/close duration and easing functions on the drop down list in a Halo ComboBox control by setting the openDuration, openEasingFunction, closeDuration, and closeEasingFunction styles.
The following example shows how you can set the Halo ComboBox control’s openEasingFunction and closeEasingFunction styles in a <Style/> block using the new PropertyReference() method in Flex 4.
