Day 10: Arranging Components on a User Interface
Notes and Corrections
- Question: I cannot understand how to make a card layout. Can you help? --
Answer: An example project should make it clearer. The BurmaShave
application (BurmaShave.java and BurmaShave.class)
displays a frame that uses card layout to display six different cards.
The project uses an array of six
JLabel objects to
serve as each of the cards. These cards are titled Card 0, Card 1, Card 2,
Card 3, Card 4, and Card 5, respectively.
Each card is added to the frame's content pane by calling the
add(String, Container) method. The
is the name of the card, and the
Container object is the
container (or component) that will serve as the card.
To show a card, the
String) method is called. This method takes two arguments: the
container that holds all the cards and the title of the card to display.
When you're using cards in a frame, window or applet window,
the parent component of those cards is the content pane of the container. In
the BurmaShave example, the frame's content pane holds the cards.
In order to display each of the cards, this application uses
some concepts you'll be introduced to fully during Day
