/**
* Component that displays a month calendar which can be used to select a day
* or range of days. By default the JXMonthView
will display a
* single calendar using the current month and year, using
* Calendar.SUNDAY
as the first day of the week.
*
* The JXMonthView
can be configured to display more than one
* calendar at a time by calling
* setPreferredCalCols
/setPreferredCalRows
. These
* methods will set the preferred number of calendars to use in each
* column/row. As these values change, the Dimension
returned
* from getMinimumSize
and getPreferredSize
will
* be updated. The following example shows how to create a 2x2 view which is
* contained within a JFrame
:
*
* JXMonthView monthView = new JXMonthView();
* monthView.setPreferredCols(2);
* monthView.setPreferredRows(2);
*
* JFrame frame = new JFrame();
* frame.getContentPane().add(monthView);
* frame.pack();
* frame.setVisible(true);
*
*
* JXMonthView
can be further configured to allow any day of the
* week to be considered the first day of the week. Character
* representation of those days may also be set by providing an array of
* strings.
*
* monthView.setFirstDayOfWeek(Calendar.MONDAY);
* monthView.setDaysOfTheWeek(
* new String[]{"S", "M", "T", "W", "Th", "F", "S"});
*
*
* This component supports flagging days. These flagged days are displayed
* in a bold font. This can be used to inform the user of such things as
* scheduled appointment.
*
* // Create some dates that we want to flag as being important.
* Calendar cal1 = Calendar.getInstance();
* cal1.set(2004, 1, 1);
* Calendar cal2 = Calendar.getInstance();
* cal2.set(2004, 1, 5);
*
* monthView.setFlaggedDates(cal1.getTime(), cal2.getTime(), new Date());
*
* Applications may have the need to allow users to select different ranges of
* dates. There are three modes of selection that are supported, single, single interval
* and multiple interval selection. Once a selection is made a DateSelectionEvent is
* fired to inform listeners of the change.
*
* // Change the selection mode to select full weeks.
* monthView.setSelectionMode(SelectionMode.SINGLE_INTERVAL_SELECTION);
*
* // Register a date selection listener to get notified about
* // any changes in the date selection model.
* monthView.getSelectionModel().addDateSelectionListener(new DateSelectionListener {
* public void valueChanged(DateSelectionEvent e) {
* log.info(e.getSelection());
* }
* });
*
*
* NOTE (for users of earlier versions): as of version 1.19 control about selection
* dates is moved completely into the model. The default model used is of type
* DaySelectionModel, which handles dates in the same way the JXMonthView did earlier
* (that is, normalize all to the start of the day, which means zeroing all time
* fields).
