Drop down on select event

I'm looking at this drop down component, and the onSelect event doesn't seem to work as I thought it should, according to the name. It seems to fire the moment I click the drop down arrow, rather than on actually selecting an item in the list.

In MS Access, where I cut my teeth, there is an event that performs when you actually select an item from the list.

Am I missing something or would this be a feature request?

onActionPerformed is your want.

Doesn't that cover any action?

What do you mean? onActionPerformed fires when you click the dropdown arrow item.

No, it's triggered by the 'intended' action of the component.
selecting/deselecting checkboxes,
activating a button,
selecting an item in a dropdown's list...

onSelect triggers when you click the arrow because you're selecting the component.
