The Expenses Calcucorder is a desktop application for recording and manipulating expense data. It has a small subset of the functionality provided by a four column Excel spreadsheet, but serves as a sort of "control example" for SWT widgets. It includes a beefed up version of Konstantin Scheglov's SWT Calendar, use of the SWT-AWT bridge, and zclipse.org's TextAutoComplete (like a Web browser address bar) widget. The philosophical inspiration comes from Joe Dominguez and Vicki Robins _Your Money or Your Life_, which suggests that knowing exactly where your money goes can remove the anxiety that uncertainty about money can cause.
