TSDL was written for the turn-based strategy game "Turious", but is a stand alone library. It provides a number of useful widgets and event handling functions. Its widgets include container, label, button, text, numbox, checkbox, and console. All of the widgets can be given individual background images and custom text. Containers and widgets can be shown and hidden individually, and will retain their visibility state. The library uses OpenGL for rendering, allowing it to be used in 3D games as well as 2D.
