32 | /**
|
||
33 | * JDateChooser is a simple Date choosing component with similar functionality
|
||
34 | * to JFileChooser and JColorChooser. It can be used as a component, to
|
||
35 | * be inserted into a client layout, or can display it's own Dialog
|
||
36 | * through use of the {@link #showDialog(Component, String) showDialog} method.
|
||
37 | * <p>
|
||
38 | * JDateChooser can be initialized to the current date using the no argument
|
||
39 | * constructor, or initialized to a predefined date by passing an instance
|
||
40 | * of Calendar to the constructor.<p>
|
||
41 | * Using the JDateChooser dialog works in a similar manner to JFileChooser
|
||
42 | * or JColorChooser. The {@link #showDialog(Component, String) showDialog} method
|
||
43 | * returns an int that equates to the public variables ACCEPT_OPTION, CANCEL_OPTION
|
||
44 | * or ERROR_OPTION.<p>
|
||
45 | * <tt>
|
||
46 | * JDateChooser chooser = new JDateChooser();<br>
|
||
47 | * if (chooser.showDialog(this, "Select a date...") == JDateChooser.ACCEPT_OPTION) {<br>
|
||
48 | * Calendar selectedDate = chooser.getSelectedDate();<br>
|
||
49 | * // process date here...<br>
|
||
50 | * }<p>
|
||
51 | * To use JDateChooser as a component within a GUI, users should subclass
|
||
52 | * JDateChooser and override the {@link #acceptSelection() acceptSelection} and
|
||
53 | * {@link #cancelSelection() cancelSelection} methods to process the
|
||
54 | * corresponding user selection.<p>
|
||
55 | * The current date can be retrieved by calling {@link #getSelectedDate() getSelectedDate}
|
||
56 | * method.
