如何将MouseEvent置于控制台中，或使Frame隐藏但功能正常？ [英] How do I put MouseEvent into Console, or make Frame hidden but functional?

问题描述

我正在使用Holtsoft的Ready To Program Java中的Console类。 我不允许使用javax.swing或将其作为applet。



我不知道如何制作节目，但需要制作：

a）仅限运行控制台窗口或

b）隐藏框架窗口但仍然可用

I''m using the Console class in Holtsoft''s Ready To Program Java for this. I''m not allowed to use javax.swing or make this an applet.

I don''t know how to make the program, but need to make it:
a) Run only in the console window or
b) Make the Frame window hidden, but still functional

import java.awt.event.*;
import java.awt.*;
import hsa.*;

public class MouseTest extends Frame
{
    int startX, startY, endX, endY;
    Console c = new Console ();
    public MouseTest ()
    {
        super ();

        MouseListener start = new MouseListener ()
        {
            public void mouseClicked (MouseEvent e)
            {
            }

            public void mouseEntered (MouseEvent e)
            {
            }

            public void mouseExited (MouseEvent e)
            {
            }

            public void mousePressed (MouseEvent e)
            {
                startX = endX = e.getX ();
                startY = endY = e.getY ();
                repaint ();
            }

            public void mouseReleased (MouseEvent e)
            {
            }
        }
        ;
        addMouseListener (start);

        MouseMotionListener end = new MouseMotionListener ()
        {
            public void mouseDragged (MouseEvent e)
            {
                endX = e.getX ();
                endY = e.getY ();
                repaint ();
            }

            public void mouseMoved (MouseEvent e)
            {
            }
        }
        ;
        addMouseMotionListener (end);

    }


    public void paint (Graphics g)
    {
        super.paint (g);
        c.clear ();
        c.setColor (Color.black);
        c.drawLine (startX, startY, endX, endY);
    }


    public static void main (String args[])
    {
        Frame frame = new MouseTest ();
        frame.setLocation (950, 100);
        frame.setSize (400, 400);
        frame.enable ();
        frame.show ();

    }
}

推荐答案

没有可见框架有什么好处？



无论如何，你可以设置Frame setVisible（false）



要查看某些控制台输出，请使用 System.out.println（creativetext）

What would be the benefit of not having a visible Frame?

Anyway, you can set the Frame setVisible(false)

To see some console output you use System.out.println("creativetext")
