获取按钮以切换卡

Question

I have a log in GUI that when i click a button, it gets text from the username and password, and if it is correct, it moves on to a new panel. i have the panel called optionPanel and i want the button to go to it specifically. all of the panels are set up as cards, so i can switch between them smoothly. I know how to make the button move to the next panel/card in the sequence, but i don't know how to make it go to the panel/card called optionPanel .

EDIT: I dont know if im being very clear, but in my head, this makes perfect sense. please tell me how i can be more clear so i can get an answer. THANKS

Answer 1

don't you just need

cardLayout.show(cards, "optionPanel");

or am i missing something completely non-obvious?

I think what you want is:

// Create the panels
JPanel loginPanel = new JPanel();
JPanel someOtherPanel1 = new JPanel();
JPanel someOtherPanel2 = new JPanel();
JPanel optionPanel = new JPanel();
JPanel someOtherPanel3 = new JPanel();

// Add them to a card layout
JPanel cards = new JPanel(new CardLayout());
cards.add(loginPanel, "loginPanel");
cards.add(someOtherPanel1, "someOtherPanel1");
cards.add(someOtherPanel2, "someOtherPanel2");
cards.add(optionPanel, "optionPanel");
cards.add(someOtherPanel3, "someOtherPanel3");

...

// Switch to the optionPanel
cards.getLayout().show(cards, "optionPanel");
