Meny and layouts

[Philip435]

Hey I need some help with my java game Im making.
I wont to have an menu with 4 options, startgame, highscore, option and quit.

They quit button is easy I just setVisible(false) but when i click on the other buttons I wont to remove the buttons and include new layouts.

Ive tried to use removeALL(); to clear the container and add() a new panel to the container but it doesnt work and Im not sure I can do it that way.

Anyone have some tips or ideas how to make an menu so please share maby Im thinking all wrong I dont know..?

if you do things like removeAll() on a JFrame or JPanel, then after adding new panels, you might need to call revalidate() or validate(). I've told people that before and they've reported back success, so go try it and let me know. If that doesn't work, post all of your code so that I can run it and I'll help.

Ive tried to use validate() but I cant se any difference, I probably did something wrong but this is my code Im kinda new to java so the code is what it is and parts like design and the number generator are far from finish.

Move the validate() call down after you add the "Game" component

c.add(Game, BorderLayout.CENTER);
			c.validate();
