DateChooser class is a general GUI based date chooser. It allows the user to select an instance of defined in package.

Programming API is similar to JFC's JColorChooser or JFileChooser. This class can be used in any application to enable the user to select a date from a visually displayed calendar.

There is a lot of improvements that can be done over this class in areas of functionality, usability, and appearance. But as is, the class can be easily used from within any Java program.

Typical usage is like:

// initial date LocalDate date = LocalDate.now()

// The owner is the JFrame of the application ("AppClass.this")

// show the date chooser DateChooser dc = new DateChooser(owner, date);

// user can either choose a date or cancel by closing if (dc.showDateChooser() == DateChooser.OK_OPTION) { date = dc.getDate(); }
