我的搜索栏是Titlepane。默认情况下会展开（false）。当我将鼠标悬停时，它将展开（true）。当我从该容器中鼠标退出时，它将再次展开（false）。
如果我扩展了Titlepane并尝试从comboBox中选择值，它将自动触发onMouseExited方法。
如何摆脱它。
我的代码：

答案 0 :(得分：0)
您应该使用事件过滤器而不是事件处理程序（更多信息：https://docs.oracle.com/javafx/2/events/processing.htm）。 遗憾的是，您无法直接在FXML中定义事件过滤器。您需要使用@FXML在控制器中注入组件，然后在initialize（）方法中手动添加事件过滤器。
