---

What is EWOL, and how can I use it?

EWOL, or Edn Widget OpenGl Layer, is a multi-platform library for creating graphical user interfaces in OpenGL. Offering a complete set of widgets.

Where can I use it?

Everywhere! EWOL is cross-platform devolopped to support bases OS:

• Linux (X11) (mouse)
• Windows (mouse) (not compile anymore ==> TODO)
• MacOs (mouse)
• Android (mouse + touch)
• IOs (touch)

What languages are supported?

EWOL is written in C++ and is not (for now) supported for other languages.

Are there any licensing restrictions?

EWOL is FREE software and all sub-library are FREE and staticly linkable !!!
That allow you to use it for every program you want, including those developing proprietary software, without any license fees or royalties.

Note:

The static support is important for some platform like IOs, and this limit the external library use at some license like :
 BSD*
 MIT
 APPACHE-2
 PNG
 ZLIB
This exclude the classical extern library with licence:
 L-GPL
 GPL
