所以,如果有人看看下面的代码并给我一臂之力,我将欠你一生。所以问题就在这里,显然如果我把playerCreationSelection
放在自己的课堂上,我可以让它发挥作用,我的问题就是让它发挥作用,在class superClass
里面我无法生活我移动东西让它工作。任何帮助都会很棒,谢谢大家!
忘记了实际上出了什么问题!那么将会发生的事情是playerCreationSelection
不是符号
public class superClass
{
public static void main(String[] args)
{
playerCreationSeletion gui = new playerCreationSeletion();
}
public class playerCreateSelection extends JFrame implements ActionListener
{
//create label
public JLabel playerCreatedLabel;
public void playerCreationSeletion()
{
setSize(WIDTH,HEIGHT);
WindowDestroyer listener = new WindowDestroyer();
addWindowListener(listener);
Container contentPane = getContentPane();
contentPane.setBackground(Color.DARK_GRAY);
contentPane.setLayout(new FlowLayout());
//create button
JButton playerCreationButton = new JButton("Create New Player");
playerCreationButton.addActionListener(this);
contentPane.add(playerCreationButton);
//create label
playerCreatedLabel = new JLabel("Welcome New Player!");
playerCreatedLabel.setVisible(false);
}
public void actionPerformed(ActionEvent e)
{
String actionCommand = e.getActionCommand();
Container contentPane = getContentPane();
if(actionCommand.equals("Create New Player"))
{
contentPane.setBackground(Color.LIGHT_GRAY);
playerCreatedLabel.setVisible(true);
}
}
}
}

答案 0 :(得分:0)
嗯,你有一个拼写错误" playerCreationSeletion()"。此外,您需要像这样调用内部类构造函数并使用setVisible和setSize。
public static void main(String[] args) {
playerCreateSelection gui = new superClass().new playerCreateSelection();
gui.setSize(500, 500);
gui.setVisible(true);
}
试试。
