Wuhoo loosely stands for W indows U sing H eaders O nly. It is an attempt to create a single-header library (in the spirit of STB [1]) for graphics related window management, compatible with both C and C++.
Wuhoo aims to make it easy to setup a system-backed drawing canvas on the three most popular windowing APIs, namely Win32, X11 and Cocoa. If requested, the API can also handle the creation of a modern OpenGL context for the user.
Wuhoo is a single header library. In a single implemetation file, you #define WUHOO_IMPLEMENTATION and #include wuhoo.h.

Windows API functions that manipulate characters generally provide two versions,
- A Windows code page version with the letter "A" used to indicate "ANSI".
- A Unicode version with the letter "W" used to indicate "wide".
In Wuhoo you #define WUHOO_UNICODE or simply UNICODE to indicate which version should be used internally. UNICODE might already by defined depending on your compilation settings. In general Wuhoo uses UTF-8 encoding for all string-relevant APIs and handles any required conversion internally.
If you plan to use the OpenGL backend, it is expected that you include your own OpenGL headers before wuhoo itself.
When using the X11 backend on Linux, the user has to link with the X11 library (-lX11). If an OpenGL context has been requested, the OpenGL library is also required (-lGL)
Depending on your package manager, you will at least need something like this:
sudo apt-get install libx11-dev
When using the Cocoa backend on Mac OS X the user has to link with the following frameworks (-framework Cocoa, Carbon, Quartz). If an OpenGL context has been requested, the OpenGL framework is also required (-framework OpenGL)
To quickly get up and running with Wuhoo, check out the provided examples. Clone this repository with:
git clone https://github.com/ViNeek/wuhoo.git
A cmake build script is provided. Simply change directory to wuhoo/examples and execute
cmake -D"CMAKE_BUILD_TYPE=Release" -H. -Bbuild
or with newer cmake (>3.13)
cmake -D"CMAKE_BUILD_TYPE=Release" -S. -Bbuild

Canvas is a very basic example that allows the user to free draw with the mouse on a system provided buffer. It showcases window setup along with basic window and mouse event handling.
-
Mandelbrot and Mandelbrot GL draw the famous fractal using a system buffer and an OpenGL context respectively.
-
Text uses another single header library(stb_truetype) to create a very basic text editor. The main focus is on showcasing how character encoding and keyboard events are handled with Wuhoo.
-
Image Viewer uses stb_image and stb_image_resize to create a basic image previewer. The main focus is on presenting the Drag n Drop event handling. Simply drag an image on the window to present it.

RTIOW is a C++ project that implements a multi-threaded version of the amazing Ray Tracing in One Weekend book. Expect something like this:
