检测用户进行的屏幕分辨率更改（Java Listener？） [英] Detect screen resolution change made by user (Java Listener?)

问题描述

我有一个启动的Java应用程序，创建一个GUI并且运行良好。如果用户更改屏幕分辨率（从1440x900切换到1280x768），我希望能够收听该事件。

I have a Java app that launches, creates a GUI and works great. If the user changes the screen resolution (switches from 1440x900 to 1280x768), I'd like to be able to listen for that event.

任何想法？

PS - 我想在事件/监听器模式下执行此操作，而不是在轮询模式下执行此操作，因此不会浪费额外的CPU周期，例如定时器不断轮询屏幕大小每隔N秒查看它是否已更改。

PS - I'd like to do this in event/listener mode, not in poll mode, so that extra CPU cycles aren't wasted on something like a timer constantly polling the screen size every N seconds to see if it's changed.

推荐答案

此帖子很旧，但是：
- 轮询屏幕大小每秒一次对性能没有任何影响
- 当屏幕调整大小时，每个窗口都应该接收一个repaint（）调用（你需要针对你定位的操作系统进行测试）

This post is old, but: - polling the screen size once every second will not have any impact on performance - when the screen is resized, every window should receive a repaint() call (you need to test this for the OSs you target)
