CardLayout不能完全隐藏其他卡吗？

Question

I am building a game, and to switch between the login screen and the game screen, I am using a CardLayout .

The code I am using to switch between the screens is

Global.gameScreen = new GameScreen(Global.connectionHandler.clientSocket);
cards.add(Global.gameScreen,"gameScreen");
((CardLayout)cards.getLayout()).show(cards,"gameScreen");

What happens, though is after I switch the screen, if I move my mouse over where the Swing controls in the login screen were, they appear and I can interact with them.

Is there a specific way I should switch cards?

Answer 1

I solved the problem by simply adding

getContentPane().remove(cards);
getContentPane().add(cards, BorderLayout.CENTER);

I don't know if this is the right way to solve it, but it worked for me.
