java - 如何在 javafx 中打开组合框弹出窗口

Question

我想在组合框的任何标签(组件)上单击或悬停时显示组合框弹出窗口，但我不知道如何触发组合框弹出面板。

Answer 1

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.
