[英]How to close previous jframe on the new open jframe
我在一次单击按钮中放置两个JFrame时遇到问题。 当单击SUC_Forms中的“ ADD RECORDS”按钮时,我有2个JFrames(SUC_Forms和add_suc),另一个新的JFrame将显示为add_suc jframe,其中包含用于注册/提交的文本框。 当我按OK确认并将所有数据插入数据库时,将弹出一个JDialogbox进行确认。 一旦我单击“确定”,两个JFrame将被处置,然后SUC_Forms-JFrame将再次显示,其中包含更新的数据。 我对当前的JFrame如何访问以前的活动JFrame有麻烦。 您能帮我解决这个问题吗? 提前致谢..
这是我的打印屏幕。
SUC_Forms代码:
add_suc add = new add_suc();
add.show();
add_suc代码:
私人void btn_okActionPerformed(java.awt.event.ActionEvent evt){
int verify = JOptionPane.showConfirmDialog(rootPane,"Are you sure you want to add this record?","", JOptionPane.YES_NO_OPTION);
if(verify == 0)

由于您要添加新记录的JFrame仍处于打开状态,因此可以在SUC_Forms中使用一个方法,在其中将新记录作为参数传递。 为此,您必须在add_suc中获得对SUC_Forms的引用。 例如,当您打开此框架时,可以将此引用传递给add_suc的构造函数。 然后,您可以调用方法以使用对SUC_Forms的引用来添加记录。
您的构造函数如下所示:
add_suc(SUC_Forms parent)
{}
然后在SUC_Forms中创建一个类似以下的方法:
public void addRecord(-here you pass the required parameters-)
{}
那么您在add_suc中的方法调用将是:
parent.addRecord(-parameters-);
希望对您有所帮助。
