A class library for developing RISC OS application programs in C++.
The RISC OS Toolkit (RTK) is a class library for developing RISC OS application programs in C++. It differs from other such libraries currently available for RISC OS in its support for automatic layout. This is achieved by specifying the relationship between different visual components (for example, the fact that they are arranged in a grid or a column). The precise coordinates are calculated by the RTK. This eliminates the need for a template editor, and allows the layout to change at run-time to accommodate varying content.
