public class JXTipOfTheDay
extends JXPanel

Provides the "Tip of The Day" pane and dialog.

Tips are retrieved from the TipOfTheDayModel. In the most common usage, a tip (as returned by TipOfTheDayModel.Tip.getTip()) is just a String. However, the return type of this method is actually Object. Its interpretation depends on its type:

Component
The Component is displayed in the dialog.
Icon
The Icon is wrapped in a JLabel and displayed in the dialog.
others
The object is converted to a String by calling its toString method. The result is wrapped in a JEditorPane or JTextArea and displayed.

JXTipOfTheDay finds its tips in its TipOfTheDayModel. Such model can be programmatically built using DefaultTipOfTheDayModel and DefaultTip but the TipLoader provides a convenient method to build a model and its tips from a Properties object.

Example:

Let's consider a file tips.properties with the following content: 

 
 tip.1.description=This is the first time! Plain text.
 tip.2.description=<html>This is <b>another tip</b>, it uses HTML!
 tip.3.description=A third one
To load and display the tips: 
 
 Properties tips = new Properties();
 tips.load(new FileInputStream("tips.properties"));
 
 TipOfTheDayModel model = TipLoader.load(tips);
 JXTipOfTheDay totd = new JXTipOfTheDay(model);
 
 totd.showDialog(someParentComponent);

Additionally, JXTipOfTheDay features an option enabling the end-user to choose to not display the "Tip Of The Day" dialog. This user choice can be stored in the user Preferences but JXTipOfTheDay also supports custom storage through the JXTipOfTheDay.ShowOnStartupChoice interface. 

 
 Preferences userPreferences = Preferences.userRoot().node("myApp");
 totd.showDialog(someParentComponent, userPreferences);
In this code, the first time showDialog is called, the dialog will be made visible and the user will have the choice to not display it again in the future (usually this is controlled by a checkbox "Show tips on startup"). If the user unchecks the option, subsequent calls to showDialog will not display the dialog. As the choice is saved in the user Preferences, it will persist when the application is relaunched.
