## Scribble Example Project

This is a simple DUIM example program for freehand line drawing. It demonstrates the following techniques:

- Defining your own window class.
- Defining your own `handle-repaint` method.
- Handling mouse events.
- Using some of the DUIM graphics functions.
- Defining a DUIM frame.
- Using a popup menu.

In Functional Developer Professional and Enterprise editions there is a companion example called OLE Scribble which demonstrates converting this DUIM application to an OLE control.
