But a lot of times I need to manage the host in a graphical interface more conveniently. Today's tutorial is to teach you to install a graphical interface.First you need to make sure that your source files in/etc/apt/sources.list already use the

Translating graphical user interface screenshots created by designers into computer code is a typical task for developers to build custom software, Web sites, and mobile applications. In this article, we demonstrate an in-depth learning approach that can be used to train an End-to-end model to automatically generate code technology from three different platforms

The postquitmessage function places the wm_quit message in the message queue. After obtaining the wm_quit message, the getmessage function returns 0 and exits the message loop. Note that getmessage only obtains the messages in the message pool of the
