Multi-touch Scratchpad Application (RTS/C++)
============================================
Demonstrates how to enable and handle multi-touch window messages in a RealTimeStylus inking application.
MultiTouch sample application. Single window, where user can draw using multiple fingers at the same time. The trace of the primary finger, the one that was put on the digitizer first, is drawn in black. Secondary fingers are drawn in six other colors: red, green, blue, cyan, magenta and yellow.
It is an example of the neccessary infrastructure for handling multi-touch events inside a Win32 application that uses Real Time Stylus API to receive multi-touch input and render the output. Demonstrates how to register a window for multi-touch inking, how to initialize IRealTimeStylus and IDynamicRenderer objects, how to derive and attach synchronous RTS plug to receive desired multi-touch events, through ordinary inking events: StylusDown, StylusUp and Packets. It tracks finger-down count and sets the appropriate cursor color. Demonstrates: IRealTimeStylus3, IRealTimeStylus, IDynamicRenderer, IStylusSyncPlugin.
