## About License
|
||||
|
||||
Since this is a toy repo, I don't spend much time about the license stuff. Currently this project use some assets and code from [ShadowPlayer](https://github.com/ShadowPower/ShadowPlayer), which have a very interesting license -- do whatever you want but cannot be used as homework -- obviously it's not a so called *free* license. I *may* do some license housecleaning works by replaceing the assets and code implementation when the code become reasonable, and the final codebase may probably released under MIT license.
|
||||
|
||||
Anyway here is a list of file which is in non-free state (with license: do whatever you want but cannot be used as homework):
|
||||
|
||||
- All png images inside `icons` folder.
|
||||
- FlacPic.h
|
||||
- ID3v2Pic.h
|
||||
- seekableslider.{h,cpp}
|
||||
|
||||
Also there are some source code which I copy-paste from Qt codebase, which released under BSD-3-Clause license by the Qt Company:
|
||||
|
||||
- playlistmodel.{h,cpp}
