推荐答案

回答完这个问题，我才发现原来是重复的JavaFX 2 自定义弹出窗格，在某些答案中包含更多上下文信息.

After answering this, I realized it was a duplicate of JavaFX 2 custom popup pane, which has a bit more context info in some of the answers.

使用 MenuButton 并在附加到 MenuButton 的 menuItem，为要在弹出窗口中显示的内容设置图形.

Use a MenuButton and in a menuItem attached to the MenuButton, set a graphic for the content you want to display in your popup.

final MenuItem wizPopup = new MenuItem();
wizPopup.setGraphic(wizBox);

final MenuButton popupButton = new MenuButton("frobozz");
popupButton.getItems().setAll(
  wizPopup            
);

这是一个完整的可执行示例.
