我正在使用网络bean的帮助开发一个java应用程序。我必须打开不同的j帧，它位于另一个包中的不同java文件中..点击一下按钮。
我还想将信息从当前页面（j帧）传输到重定向的j帧。 文本字段内容，单选按钮下拉列表等信息。
帮助我在按钮点击动作监听器中写什么....

答案 0 :(得分：1)
您可以使用actionPerformed()方法中的下一个代码执行此操作：
AnotherFrame f = new AnotherFrame();
f.setNeededData(/*object*/);
f.pack();
f.setVisible(true);
AnotherFrame是您要创建和展示的JFrame。
setNeededData(/*object*/)是您的框架传输requiredData的方法。
最后两行显示它。
答案 1 :(得分：0)
在单击按钮上，您只需创建要打开的JFrame的对象，它将在其中加载组件（因为您必须在默认构造函数中调用initComponents（）方法）。 要将参数从一个帧传递到另一个帧，您只需创建一个POJO并在当前帧中设置其属性，并在创建对象时将此对象传递到目标帧。 我希望这会有所帮助..
答案 2 :(得分：0)
在按钮上单击ActionEvent：
创建具有框架创建功能的类的对象，并使用该对象调用newFrame函数：
newframe frm = new newframe(this);
frm.NewFrame();
假设此函数位于包org.xyz.frame;
public void NewFrame(){
JFrame frame = new JFrame("Frame2");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
try
{
for (LookAndFeelInfo info : UIManager
.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
JPanel panel = new JPanel();
frame.getContentPane().add(BorderLayout.CENTER, panel);
frame.setLocationRelativeTo(ui);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
frame.setResizable(false);
}
