JDialog在空闲时超时

如何在JDialog空闲时设置例如90秒的超时时间？

一旦没有动作，移动，选择在JDialog中完成90秒就会退出。

此线程提供超时但没有空闲条件 – 我可以在Java Swing JDialog框上设置一个计时器，在几毫秒后关闭

谢谢！

好的，所以最大的问题是获得有关用户交互的足够信息。 您可以尝试使用AWTEventListener ，这是一种监视AWTEvent通过EventQueue并且在大多数情况下，应该为您提供有关可能的交互的足够信息。

因为并非所有事件都通过EventQueue ，所以在某些情况下可能并不总是有效，在这种情况下，您需要将附加的侦听器附加到组件上，从而给您带来麻烦并手动重置计时器……

您还可以查看Application Inactivity以获得可在任何窗口（框架，对话框）上使用的更通用的解决方案。

您只需在一段时间不活动后提供要调用的Action，并自动调用Action。
