如何通过Xlib观察连接的监视器中的变化? [英] How to observe changes in connected monitors via Xlib?

问题描述

我正在尝试编写一个程序，该程序将检测插入的外部监视器，并通过Xlib自动启用和配置它们.我知道有XRandr扩展名允许这样做.我的问题是，如何启用向应用程序接收XRandr事件?我应该使用哪个事件掩码?我知道xev应用程序可以做到这一点.

I'm trying to write a program that would detect external monitors being plugged in and automatically enable and configure them through Xlib. I know that there is XRandr extension that allows this. My question is, how do I enable receiving XRandr events to my application? What event mask should I use? I know that xev app is able to do this.

推荐答案

Xev的源代码:

• http://cgit.freedesktop.org/xorg/app/xev/tree/

或者:

• git clone git://anongit.freedesktop.org/xorg/app/xev
