+ turtleDemo - Help
+
+ ----------------------------------------------
+
+ This document has two sections:
+
+ (1) How to use the demo viewer
+ (2) How to add your own demos to the demo repository
+
+
+ (1) How to use the demo viewer.
+
+ Select a demoscript from the example menu.
+ The (syntax coloured) source code appears in the left
+ source code window. IT CANNOT BE EDITED, but ONLY VIEWED!
+
+ - Press START button to start the demo.
+ - Stop execution by pressing the STOP button.
+ - Clear screen by pressing the CLEAR button.
+ - Restart by pressing the START button again.
+
+ SPECIAL demos are those which run EVENTDRIVEN.
+ (For example clock.py - or oldTurtleDemo.py which
+ in the end expects a mouse click.):
+
+ Press START button to start the demo.
+
+ - Until the EVENTLOOP is entered everything works
+ as in an ordinary demo script.
+
+ - When the EVENTLOOP is entered, you control the
+ application by using the mouse and/or keys (or it's
+ controlled by some timer events)
+ To stop it you can and must press the STOP button.
+
+ While the EVENTLOOP is running, the examples menu is disabled.
+
+ - Only after having pressed the STOP button, you may
+ restart it or choose another example script.
+
+ * * * * * * * *
+ In some rare situations there may occur interferences/conflicts
+ between events concerning the demo script and those concerning the
+ demo-viewer. (They run in the same process.) Strange behaviour may be
+ the consequence and in the worst case you must close and restart the
+ viewer.
+ * * * * * * * *
+
+
+ (2) How to add your own demos to the demo repository
+
+ - place: same directory as turtledemo/__main__.py
+
+ - requirements on source code:
+ code must contain a main() function which will
+ be executed by the viewer (see provided example scripts)
+ main() may return a string which will be displayed
+ in the Label below the source code window (when execution
+ has finished.)
+
+ If the demo is EVENT DRIVEN, main must return the string
+ "EVENTLOOP". This informs the demo viewer that the script is
+ still running and must be stopped by the user!
+
+ If an "EVENTLOOP" demo runs by itself, as with clock, which uses
+ ontimer, or minimal_hanoi, which loops by recursion, then the
+ code should catch the turtle.Terminator exception that will be
+ raised when the user presses the STOP button. (Paint is not such
+ a demo; it only acts in response to mouse clicks and movements.)
