The Pie Menu is useful when you want the user to concentrate his attention only
to the context of the book, without displaying buttons on the screen.
The Pie Menu script is written in the background. Only the first page includes a
supplementary script that avoids the Pie Menu appearing on entering the book
for accidental buttonDown messages while loading the file.
Remember to keep the Pie Menu in the first layer.
Hotword like this should have the precedence over the Pie Menu.
To create your own application, you should copy the following parts:
- book, background and first page scripts
- the PieMenu group (on every page of your book) and the field called
"Action" in the background (or backgrounds)
I suggest anyway to do these operations once your book is completed.....

I look forward to hearing from you !
Your suggestions, comments and criticisms are very helpful for me.
They are new energy for everybody's brainstorming to find new interface solutions.

PIE MENU v. 2.0 by Paolo Tosolini - October '92
This is the new release of the Pie pop up Menu implemented in Toolbook using Openscript.
Now you can navigate though the pages of this book without any menu appears on the screen. Just click the mouseButton and (while keeping pressed it) move the pointer to :
RIGHT for NEXT PAGE
LEFT for PREVIOUS PAGE
UP for page called "Index"
DOWN for BACK
However, if you keep pressed the mouseButton for more than half second, the Pie Menu will be visible and you can see how it works while you move the pointer around it.
The action of changing page starts when you release the mouseButton.
You can make the PieMenu disapper just releasing the mouseButton in the centre of the Pie.

This page is called INDEX and could be the summary page of your book
The PieMenu includes the option to go to a page called "Index".
To change this option, you should replace the text "Index" in the
PieMenu field and the <go to page "Index"> script in the buttonUp
handler of the background.
The textFields of the PieMenu are called "GoNext, GoPrev, GoBack,
GoIndex". The entire group is called "PieMenu".
To avoid undesired flickering of the commands, set the DrawDirect properties of the PieMenu fields to False. For better visual results, in this book there are no DrawnDirect objects.
New improvements:
The PieMenu v.2.0 may result useful to navigate in a book in a linear way.
Four choices are not enough to substitute completely a traditional pull down menu.
In my next release I'll try to implement a kind of hierarchy of the commands .
