Package com.rubecula.spreadsheet Description

Spreadsheet Package: sample application for JQuantity.

This spreadsheet application is designed and implemented solely as a sample application for the JQuantity package. It does not purport to be a particularly good or useful spreadsheet, although it does work.

It is implemented in Swing.

Invoking the spreadsheet

The AppSpreadsheet.main method takes three optional string run-time arguments:

1. "JEP": if this argument is present, the JEP expression parser will be used to parse expressions which cannot be parsed by the native parser of the spreadsheet package. The com.rubecula.jarg package must be available, as must the jep.jar.
2. This is the name of a spreadsheet file which will be automatically opened at startup, assuming it exists.
3. If the previous argument is present, this is the name of a file to which the opened spreadsheet will be immediately saved after startup.
