This program creates and maintains a JavaFX GUI for a simple mortgage calculator.
It demonstrates among other things how event filtering can be applied to make
sure that the numbers entered by the user into the text fields remain valid, such
that the calculations can be carried out properly. In addition it demonstrates
formatting numbers (according to the default Locale) with and without currency.
An overview of JavaFX event handling can be found at
https://docs.oracle.com/javafx/2/events/processing.htm
(as of 2019-02-17).
Hint: if you wish to look at the ooRexx code with syntax highlighting, then you can
use the free and open-source editor "[g]vim"
, which is available for practically
all platforms and can be downloaded from its homepage at
http://www.vim.org/.
The following files and Rexx packages (Rexx programs) are used in this application:
MortgageCalculator.rex
" or
(on MacOSX use rexxj.sh
instead) "rexxj.cmd MortgageCalculator.rex
"
