selectlevelp.java~23~

用java实现的游戏例子(包括俄罗斯方块等),值得借鉴.

package dialog;

import java.awt.*;
import java.awt.event.*;
import TFrame;

public class selectLevelP extends Panel
{
    TFrame m_tFrame;
    Dialog m_dialog;

    Scrollbar scrollbar1 = new Scrollbar();
    Label label1 = new Label();
    Button button1 = new Button();

    public selectLevelP(TFrame tFrame,Dialog d)
    {
        m_tFrame=tFrame;
        m_dialog=d;
        try
        {
            jbInit();
            System.out.println(tFrame.m_tetrics.getPlayLevel());
            scrollbar1.setValue(tFrame.m_tetrics.getPlayLevel());
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
    private void jbInit() throws Exception
    {
        this.setLayout(null);
        scrollbar1.setMaximum(15);
        scrollbar1.setMinimum(1);
        scrollbar1.setOrientation(0);
        scrollbar1.setPageIncrement(1);
        scrollbar1.setValue(5);
        scrollbar1.setVisibleAmount(1);
        scrollbar1.setBounds(new Rectangle(39, 14, 166, 19));
        scrollbar1.addAdjustmentListener(new java.awt.event.AdjustmentListener() {
            public void adjustmentValueChanged(AdjustmentEvent e) {
                scrollbar1_adjustmentValueChanged(e);
            }
        });
        label1.setText("你选择的的等级：5");
        label1.setBounds(new Rectangle(50, 42, 138, 26));
        button1.setLabel("确定");
        button1.setBounds(new Rectangle(84, 73, 81, 26));

            }
        });
        this.add(scrollbar1, null);
        this.add(button1, null);
        this.add(label1, null);
    }

    void button1_actionPerformed(ActionEvent e)
    {
        int nLevel=scrollbar1.getValue();
        m_tFrame.m_tetrics.setPlayLevel(nLevel);
        m_dialog.dispose();
    }

    void scrollbar1_adjustmentValueChanged(AdjustmentEvent e)
