2. Temperature Converter

Notes:

• FOAM already has three more polished example of how to do this.

3. Flight Booker

Notes:

• It didn't make sense to show when the date was an invalid format, because of the use of a Date Picker, so instead I added validation to make sure that the departure date is today or later and that the return date is the departure date or later if it's a two-way flight.

5. CRUD

Notes:

• See the Todo App Tutorial, which shows how to make a full-featured CRUD controller.
• TODO: Show how to replace the prefix search with the full Google query language with the same amount of code.
• TODO: Show how to use FOAM's generic CRUD controler to create a more full-featured version without code.
• TODO: Show how to add client/server support.

6. Circle Drawer

(Click to create or select a circle. Right-click to adjust diameter.)

Notes:

• TODO: Add "Edit Diameter..." menu on right-click.

7. Cells

Notes:

• FOAM has support for context-free grammars, which this code uses, so it would be just as easy to support regular mathematical expressions as it is to support the add(), mul(), etc. syntax.
• I've pre-loaded a sample spreadsheet taken from Visicalc.
• I added simple load and save support.
• TODO: Add graphing support.
• TODO: Add formula syntax error reporting.
