Why should I use OpenGUI instead of writing my own GUI system?

There are a number of reasons you might want to write your own GUI system. The most common reasons are flexibility and speed. OpenGUI is easily extended with new widgets, and employs caching mechanisms to ensure a low impact on performance. Additionally, writing your own GUI system can take a lot of time away from more important development. Using a GUI library can help keep your project on track, and we believe it doesn't have to mean sacrificing flexibility or speed.

Why was OpenGUI created?

OpenGUI was started because I needed a flexible, efficient, and easily extensible GUI system. Despite finding several existing solutions, none of them met my strict requirements for ease of use, efficiency, features, and customization. Although contributing to an existing project would have been preferable, the core design of all existing libraries I found did not appear capable of accepting the necessary changes in a clean manner. Because of this, the only solution was to create a new library designed from the ground up to support the end goals.

Which renderers can I use with OpenGUI?

OpenGUI can be extended to work with any system capable of rendering textured triangles. However, OpenGUI comes with a prebuilt renderer for use with Ogre, as well as a reference renderer for OpenGL that should need only minor alterations to use in a production environment.

Can I use OpenGUI in a commercial product?

Yes. OpenGUI is licensed under the BSD license, which allows for use in both commercial and open source applications. A copy of the license is available online here, and is distributed with OpenGUI source and SDKs in the LICENSE.txt file.

How much does OpenGUI cost?

Nothing. OpenGUI is a free open source library. There is no charge for its usage in any application.

Where can I get support for OpenGUI?

Free community support is provided for OpenGUI via the forums and IRC. We'd like to provide commercial level support in the future, but we're still working out all of the details for such an endeavor.
