私は NetBeans を使用しており、JDialog に拡張するクラスがあり、そのダイアログ ボックス内にタブ付きペインを作成しました。タブ付きペインには 6 つの異なるタブがあり、もちろん 6 つの異なるパネルがあります。私がやりたいことは、さまざまなタブをクリックすると、ペイント メソッドで図が描画されることです。
私の質問は、Dialog クラスから呼び出される別のクラスのペイント メソッドを 1 つだけ使用して、さまざまなパネルに描画するにはどうすればよいかということです。
Dialog クラスのコードは次のとおりです。
package GUI;
public class NewJDialog extends javax.swing.JDialog{
/**
* Creates new form NewJDialog
*/
public NewJDialog(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.

これは、ペイント メソッド用に作成した別のクラスです。
import java.awt.Graphics;
import javax.swing.JPanel;
public class Lienzo {
private int width = 5;
private int height = 5;
private int y = 5;
private int x = 0;
private int x1 = 0;
public Graphics Draw(Graphics g, int[] pistas) {
//Im not sure if this is the correct way to do it
//The diagram gets drawn according to values from an array
//The array is not always the same thats why I used the different Panels
for (int i = 0; i < pistas.length; i++) {
x = pistas[i];
x1 = pistas[i + 1];
g.drawOval(x, y, width, height);
g.drawString(Integer.toString(x), x, y);
g.drawLine(x, y, x1, y);
}
return g;
}
}
私のプログラムで何をしようとしているのか、皆さんが理解してくれることを願っています。
