无法在java框架中看到所有文本

标签: java swing jpanel frame jscrollpane

我有一个问题我无法解决。我是编程新手。

主框架(glavnoOkno)打开正常。单击主框架上的按钮时,将打开新框架。并且您无法在其中看到所有文本或文本框。那些可以在屏幕宽度上移动的,但其他的不是。

我试过.pack(),但它没有用,然后我尝试了ScrollPane(),但这也没有用(可能是因为我不知道把它放在哪里:().. 无论如何,我的代码分为四个类。在这里,我把两个,我认为重要。如果我错了,我也可以把其他两个。没有变量是英文的,我希望这不是一个大问题。

所以...请帮忙。这是主框架的类。并在底部定义第二帧。

    import java.io.*;
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;

     public class GlavnoOkno extends JFrame implements ActionListener {
          private JLabel naslov;
      private JButton gumbVnesiEleganten;
      private JButton gumbKoncaj;
      private JPanel plosca;
      private JScrollPane zvitek = new JScrollPane();
      private JTextArea tekstnoOkno = new JTextArea();
      private Trgovina trgovina;

public void setTrgovina(Trgovina trgovina) {
    this.trgovina = trgovina;
}

public Trgovina getTrgovina() {
    return trgovina;
}

public JTextArea getTekstnoOkno() {
    return tekstnoOkno;
}

public GlavnoOkno(Trgovina trg) {
    setTrgovina(trg);

    Container cp = this.getContentPane();
    cp.setLayout(new BorderLayout());

    naslov = new JLabel("Prosim, da pritisnete ustrezen gumb ...");
    cp.add(naslov, BorderLayout.PAGE_END);

    plosca = new JPanel();
    cp.add(plosca, BorderLayout.PAGE_START);

    gumbVnesiEleganten = new JButton("Vnesi eleganten cevelj.");
    plosca.add(gumbVnesiEleganten);
    gumbVnesiEleganten.addActionListener(this);

    gumbKoncaj = new JButton("Koncaj");
    plosca.add(gumbKoncaj);
    gumbKoncaj.addActionListener(this);

    zvitek.setAutoscrolls(true);
    cp.add(zvitek, BorderLayout.CENTER);
    zvitek.getViewport().add(tekstnoOkno);

    setSize(300, 400);
    setTitle("Glavno okno programa");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public void actionPerformed(ActionEvent e) {

    Object m = e.getSource();;

    if (m == gumbVnesiEleganten) {
        Eleganten novi = null;
        try {
            JFrame oknoVnesiEleganten = new VnesiEleganten(novi, this);
            oknoVnesiEleganten.setVisible(true);
            oknoVnesiEleganten.pack();
            trgovina.getCevlji1()[0] = novi;
        } catch (Exception e1) {
            getTekstnoOkno().append("Napaka - poskusite znova!\n");
        } 
    } 
    else if (m == gumbKoncaj) {
        System.exit(0);
    }
}

}

这是第二帧的课程。

            novi.setSpol(poljeSpol.getText());
            novi.setVisinaPete(Double.parseDouble(poljePeta.getText()));
            setEleganten(novi);
            glavnoOkno.getTekstnoOkno().append("" + novi + "\n");
            poljeCena.setText("");
            poljePopust.setText("");
            poljeMaterial.setText("");

        } catch (Exception e1) {
            glavnoOkno.getTekstnoOkno().append("Napaka - poskusite znova!\n");
        }
    }
}

}

附注:非英文变量名称使得读取代码非常困难。避免这样做。


认为你应该使用JScrollPane。试试这个:

JPanel yourPanel = new JPanel();
// all kinds of code that adds elements to it
// now wrap the panel in a scroll pane
JScrollPane scrollPane = new JScrollPane(yourPanel);

// and use the scroll pane instead of your main component
Container cp = this.getContentPane();
cp.setLayout(new BorderLayout());
cp.add(scrollPane, BorderLayout.CENTER);
