Quick Tip: Set a ComboBox’s dropdown height with rowCount

I looked and looked for a way to change the height of the dropdown list in a ComboBox in AS3. It can be done by setting the rowCount property on the ComboBox.

rowCount defaults to 5, so if you need to make a ComboBox’s list smaller, it’s actually quite easy:

myComboBox.rowCount = 4

That makes sense, but it’s not immediately obvious. I thought I’d put that up here in case anybody else runs into the same thing.
