JFrame和JDialog链接

Question

我正在使用Visual swing插件进行蚀-这就是问题所在。 在我单击按钮时，它应该显示对话框（或其他jForm，但我已阅读到应用程序只应使用一个jfrom）并隐藏第一个没有问题的。 但是在第二种形式上，我需要做同样的事情，单击按钮时，我需要将第一种形式显示回来，然后将第二种形式放置。 这是代码（可能排序不大，因为在这种视觉摆动中我找不到自己的出路）

Answer 1

我通过您的代码看起来，看看你已经创建Jbutton将和所有的，但我没有看到任何地方的ActionListeners已被添加到任何东西 。 没有AcionListeners，JButton不会在按钮按下时调用行为。 我认为您首先需要解决此问题，还需要阅读在Oracle Java教程站点上找到的基本Swing教程。

Answer 2

在Objekat类中，为JFrame创建一个实例变量，例如private JFrame frame; ，现在在构造函数中，您可以从调用类中获取JFrame的Object，获得此引用，例如this.frame = frame; ，现在将您的以下给定方法修改为此表单：

private void mouseMouseClicked(MouseEvent event) 
{
    frame.setVisible(true);
    this.dispose();
}

并如下所述修改您的以下方法：

public void btnEkipaMouseMouseClicked(MouseEvent event) 
{
    this.setVisible(false);
    Objekat o = new Objekat(this);
    o.setVisible(true);
}

在我看来，这就是完成此工作所需的全部。 由于在您的示例中，您在创建Objekat类的对象时未传递任何内容，因此我认为未为其分配父对象，因此Objekat的actionPerformed(...)方法未按预期工作，请尝试使它们变化，希望它会起作用。

Answer 3

优秀的教程摆在这里

若要在单击按钮时打开任何框架或对话框，则必须在执行动作的方法中创建该类的对象，并将其可见性设置为true； 默认情况下，在摆动中，对于我们创建的框架，可见性为false。

而不是写这个

  public void btnEkipaMouseMouseClicked(MouseEvent event) {
    this.setVisible(false);
    Objekat o = new Objekat();
    o.setVisible(true);

代码最好像这样编写actionlinstener

btn.addActionListener(new ActionListener(){
   public void actionPerformed(ActionEvent e){ Objekat o = new Objekat(this);}
});

上面的代码与您的代码相同，但是它使用默认的事件侦听器，而不是创建一个新的事件侦听器。

这是因为如果标准库中有可用的动作侦听器，那么为简单的按钮单击事件创建自定义处理程序将不值得称赞...如果我错了，请告诉我...

如果要放置第二个框架并再次显示第一个框架，则可以在类中创建两个框架的引用并为其分配对象，同时构造该类的框架，如果需要的话，可以为两个框架提供五个确定的引用对它们中的任何一个进行任何操作。

public class Intervencije extends JFrame {
Objekat prev, next;
}

构造函数将像这样

public Objekat (Objekat prev) {
   //the next frame is obviously the onn in which u r working
next = this;
prev.setVisible(true);
next.setVisible(false);//you can do whatever you want with prev and next
}

动作听者会像这样

Objekat prev = this;
public void actionPerformed(Actionevent e){
    Objekat newFrame = new Objekat(prev)
}

Answer 4

当您要打开新框架或对话框时，必须将JButton的ActionListeners事件用于JButton ActionListeners事件，请参见ActionListener上的示例
