我从JFrame调用JDialog 但问题是当我退出JDialog框时，整个程序退出意味着JFrame窗口也退出。 我不仅可以退出JDialog框窗口。 我如何关闭JDialog盒子？我如何才能关闭JDialog盒子？
在这里输入的代码
package subtitlemakerofvedio;
public class About extends javax.swing.JDialog {
/** Creates new form About */
public About(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.

jLabel1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/about.png"))); // NOI18N
jLabel1.setText("jLabel1");
jLabel2.setFont(new java.awt.Font("Tahoma", 1, 15));
jLabel2.setText("SubTitle Editor ");
jLabel3.setText("A simple subtitle editor of vedio ");
jLabel4.setText("<html>You can make bangla and english subtitle using this software");
