我正在开展一个工作项目，并遇到了一些障碍。该项目实际上涉及允许用户生成XML文件。首先向用户呈现许多GUI - 那些看起来取决于在第一GUI上做出的选择。一旦用户使用GUI进行操作，数据将用于填充JTable，然后一旦确认放入XML文件。
虽然听起来很愚蠢，但是我遇到了JFrames的问题。一旦用户填写其中一个GUI屏幕上的信息并点击＆＃34;确认＆＃34;按钮我希望JFrame消失，然后出现。我没有问题让下一个出现，但由于类的设计我不能弄清楚如何正确使用JFrame.dispose（）方法。我将在下面发布我的课程：

}
}
具体而言，第一个GUI上的JComboBox选择将决定下一个GUI出现。
confirmButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
}else if(fileTypesComboBox.getSelectedIndex()==1){
type="HOME";
}else if(fileTypesComboBox.getSelectedIndex()==2){
type="CLEARED";
}
}
});
所以现在我只有用户选择JComboBox中的第一个选项的逻辑。这工作正常，新的GUI打开，但它只是在第一个JFrame的顶部打开。我尝试在动作监听器中使用JFrame.dispose（），如下所示：
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
JFrame.dispose();
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
然而，它被Eclipse标记为错误：
Cannot make a static reference to the non-static method dispose() from the type Window
我理解为什么会出现这种错误以及问题是什么，但我不知道如何修复。我尝试了很多方法，但似乎没有任何工作。我非常感谢任何帮助让第一个JFrame在另一个JFrame打开时关闭。
答案 0 :(得分：1)
如果你知道点击的按钮，那么你需要找到按钮所属的框架。
因此，在按钮的ActionListener中，您可以使用以下代码：
Component component = (Component)e.getSource();
Window window = SwingUtilties.windowForComponent(component);
window.dispose();
