How to check if the SWT combo is currently opened?

Question

I have an SWT combo box in my GUI. Is it possible to check if the combo box has been opened? (I've a mechanism which refreshes the state shown in the combo box, when a user opens it sometimes it jumps between user selection and that what the algorithm thinks is fine, the user selection has a priority over everything else).

Answer 1

Combo SWT component have method getListVisible() which returns flag if combo dropdown list part is visible or not.. see documentation for combo for details.
