如何使用 X window 为 Linux 操作系统界面创建 GUI？

Question

Can you provide me a surface level knowledge about this.

How can I use linux's latest kernel and X windows GUI to create my own Embedded OS interface?

Answer 1

If you want to learn to make your own distribution, look at linux from scratch. A pre-existing embedded distribution may be more what you are looking for. Some are uclinux-dist, openembedded, poky, ltib, buildroot.

When you say "small" what do you mean by small? Small means reduced functionality.

1. The smallest is writing your own code that writes to the frame buffer. Your GUI may look like space invaders.
2. Bigger would be to use a direct to framebuffer toolkit like Nano-X
3. Bigger again is DirectFB.
4. Bigger again is a high level toolkit (GTK or Qt) on top of DirectFB
5. And the biggest is X with a window manager and high level toolkit.

Having "learned" already, I would use whatever comes with the platform you are developing on.

End Dump.

First suggestion, code HTML and use a browser. All of the heavy lifting will be done for you. More to the point, most embedded OSen do not live on systems with keyboards, video, and mice. Exporting everything to a remote web client though a web server is the standard way of doing things.

Second suggestion, use a high level toolkit, like Qt, KDE, or Gnome. Coding in low level X is painful.
