CardLayout- how to deal with it?

[Stefan Elfvinge]

Hi! I have a class extending JPanel(ScoreBoard) acting as a scoreboard for a game, ScoreBoard
contains 5 Jpanels, each containing a JTable.
ScoreBoard uses a CardLayout. Adding an instance of ScoreBoard to my JFrame(GameArea) doesn't work.
It compiles, runs, showing all others components(using Flow- or BorederLayout). But ScoreBoard remains invisible!!!??? If I change ScoreBoard's
LayoutManager to something other than CardLayout, it works!!?? What to do...

hi
you put one empty panel in jFrame(game) and set cardlayout to that, then add Jpanel(scoreboard) to that panel.then it works fine .

Thanks for instant reply!
Do u mean that my mistake is that I first build my
ScoreBoard(JPanel), then add it to the JFrame?
From your advise I take it I should add an additional JPanel, giving it a CardLayout, and THEN, add my ScoreBoard instance to that. Why is this "extra" panel necessary?

Stefan, could u post some of the code? to show us the panel and how u add it.
from what i know, i dont think u need the extra panel. the idea should work.

Are you doing the panel.show() for the cardlayout?

[Roy Ben Ami]

Paul, i think u dont have to do the show().
if im not mistaken, the card layout will show the FIRST component added to it unless u use next() show() or any of the other functions.

Thanks for input, here's some code:
private GameController controller
private boolean[] markedValues;
private int summa;
private int bonus;
public ScoreBoard(GameController controller)
{
super(new CardLayout());
setBorder(new EtchedBorder());
this.controller = controller;
markedValues = new boolean[19];
for(int i = 0; i<markedValues.length; i++)
markedValues[i] = false;
}

// To be called from “GameController”
public void addScoreBoardText(DicePlayer player)
{
String name = player.getName();
JPanel panel = new JPanel(new BorderLayout());
panel.setBorder(new TitledBorder(new EtchedBorder(),
name + " scoreboard"));
JTable scoreBoardText = new JTable(19, 2);
setupScoreBoardText(scoreBoardText);
panel.setBackground(Color.lightGray);
panel.add(scoreBoardText, BorderLayout.CENTER);
// L�gg texten i panelens container
CardLayout cL = (CardLayout)this.getLayout();
cL.addLayoutComponent(panel, name);
}
