在国外怎么做网站,网站收录 作用,微信商店小程序怎么弄,网线制作的标准X11是Linux发行系统中广泛采用的显示协议#xff0c;各个系统基本上都支持XLib库#xff0c;作为底层接口#xff0c;XReparentWindow接口的功能就是重新设置父窗口#xff0c;注意这个可以跨进程设置父窗口#xff0c;例如将已经运行的进程的父窗口设置自己的程序Wid各个系统基本上都支持XLib库作为底层接口XReparentWindow接口的功能就是重新设置父窗口注意这个可以跨进程设置父窗口例如将已经运行的进程的父窗口设置自己的程序Wid即可将第三方进程嵌入到自己的程序窗口中自己用这个接口写了一段代码在UOS上运行的正常后面跑在Kylin 4.0.2和V10上程序出现了一些难以琢磨的情况嵌入的程序无法focus查阅到qt的container容器可以完成这个功能查阅了qt4和qt5的源码发先程序嵌入确实不是简简单单的XReparentWindow调用后续还涉及到各种消息转发操作后续学习。
