A patched version of Chameleon(default window decoration) on DeepinV20, which allows to show your windows' menu on the titlebar.

Inspired by material-decoration and copied lots of code from it :)

1. install dde-globalmenu-service and set it with autostart(right click on the launcher)
2. sudo apt install libkf5config-bin libqt5quickparticles5 libqt5quickshapes5 (please use ldd to check the dependencies)
3. modify ~/.gtkrc-2.0, add gtk-modules=appmenu-gtk-module
4. modify ～/.config/gtk-3.0/settings.ini，add gtk-modules=appmenu-gtk-module under [Settings]
5. download the release zip file in release page(only for deepinv20. other distributions need to compile from source)
6. copy the libdde-chameleon.so to /usr/lib/x86_64-linux-gnu/qt5/plugins/org.kde.kdecoration2(you should backup the one provided by the system)
