How to open Combo Box popup in javafx

combobox, java, javafx

Solution

`comboBox.show()`

Requests that the ComboBox display the popup aspect of the user interface. As mentioned in the ComboBoxBase class javadoc, what is actually shown when this method is called is undefined, but commonly it is some form of popup or dialog window.

Problem

I want to show combo box popup while click or hover on any label(component) instade of combo box and I don't know how to trigger combo box popup panel.
