Java中的用户界面框架
我有一个带有“驱动程序GUI”java文件的程序,可以创建JFrame及其规范
public static void main(String[] args)
{
/*Create a frame (outside box) and write what text
will be displayed as the frame title*/
JFrame frame = new JFrame("PHILIP MCQUITTY");
//give frame a size
frame.setSize(520,375);
//set location on the computer screen will frame appear
frame.setLocation(400, 166);
//use this so when you press X in corner, frame will close
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Add your panel to the frame. name must match Panel class name
frame.setContentPane(new GpaCalc());
//frame.setResizable(false);
// always include
frame.setVisible(true);
}
这个GUI调用。setContentPane方法,并将其连接到我的资源类,我在其中创建了所有的JLables、JButtons和JTextfields
资源代码的一个片段如下所示:
public class GpaCalc extends JPanel
{
private JLabel GPALabel, c1, c2, c3, c4, c5, c6, c7, g1, g2, g3, g4, g5, g6, g7;
private JTextField Class1, Class2, Class3, Class4, Class5, Class6, Class7, Grade1, Grade2, Grade3, Grade4, Grade5, Grade6, Grade7;
private double GPA1, GPA2, GPA3, GPA4, GPA5, GPA6, GPA7, GPA, BigDec;
public GpaCalc()
{
setLayout (new FlowLayout());
JPanel panel=new JPanel();
//Class Labels
GPALabel = new JLabel ("0.00000000000000");
GPALabel.setFont (new Font("Times New Roman", Font.BOLD, 60));
GPALabel.setForeground (Color.red);
所以我的问题是,在我将JFrame和setResizeable的维度设置为false(.setResizeable(false));)之后,如何使JFrame垂直滚动
