Easy to learn and support

Even a C beginner could master GuiLite quickly. The source code only uses basic C++ features (class, virtual function). We chose C++ as it could make the code size significantly smaller and easier to read. - 📚Documentation - How to use GuiLite? - Design specification - How to Layout widgets? - How to build unicode font/bitmap resource? - How to switch theme? - How to dispatch messages? - UML chart of GuiLite core - 📈Learning steps 1.
