Add Tiles

Adding a tile to the window

Add a LetterPanel to WordBuilder so you can see what a tile looks like.

1. Add a private JPanel instance variable called mainPanel, initialized by calling JPanel’s constructor.
2. In the main panel section of initGUI(), add mainPanel to the center of the window. Use JFrame’s add() method and BorderLayout’s CENTER variable.
3. Create a new LetterPanel object called letterPanel, with the letter “A” and 1 point, and add letterPanel to mainPanel using JPanel’s add() method.
