What is Emacs Application Framework?

Emacs Application Framework is a development framework that developers can develop any PyQt program and integrate into Emacs.

This framework mainly implements three functions:

Integrate PyQt program window into Emacs Frame using Xlib Reparent technology
Listening to EAF buffer's keyboard event flow and controlling the keyboard input of PyQt program via DBus IPC
Created a window compositer to make the PyQt program window adapt Emacs's Window/Buffer design

Using this framework, you can use PyQt develop powerful graphics programs to extend Emacs

Report bug

If you have any problem with eaf, please use command "emacs -Q" start Emacs first.

Then test again, if "emacs -Q" works fine, it's must be something wrong with your emacs config file.

If "emacs -Q" still have problem, please report bug

Why this awesome framework can't works with MacOS?

There are mainly three obstacles:

I can't make dbus/python-dbus works on MacOS High Sierra
This framework need use X11 reparent to stick Qt5 window to emacs frame, but i don't know how to make X11 works on MacOS.
Qt5 QGraphicsView/QGraphicsScene can't work MacOS, specify QGraphicsVideoItem can't work.
