Netbeans模板AboutBox Java [英] Netbeans template AboutBox Java

问题描述

我以前在netbeans 6.9.1中使用过此代码，但在7.1.1中似乎不起作用，它在.getApplication()下划线并带有提示找不到符号".

I used this code previously in netbeans 6.9.1 but it does not seem to work in 7.1.1, it underlines .getApplication() with the hint "cannot find symbol".

如何重新进行这项工作?

How can I make this work again?

JFrame mainFrame = TestProject.getApplication().getMainFrame();
AboutBox newAboutBox = new  AboutBox();
newAboutBox.setLocationRelativeTo(mainFrame);
TestProject.getApplication().show(newAboutBox);

此处是一个类似的问题，但是该解决方案无效.

Here is a similar question, but the solution does not work.

推荐答案

我通过重新安装netbeans 6.9.1找到了解决方案.似乎有一个内置库不在7.1.1中.我还发现我使用的模板是桌面应用程序"模板.

I found the solution by re-installing netbeans 6.9.1. It appears that there is a built-in library that is not in 7.1.1. I also found that the template I used was the "Desktop Application" template.

这是我从中想到的解决方案:

This is the solution I came up with from that:

TestProject类:

TestProject class:

import org.jdesktop.application.Application;
import org.jdesktop.application.SingleFrameApplication;

public class TestProject extends SingleFrameApplication {

    @Override protected void startup() {
        show(new AppView(this));
    }

    @Override protected void configureWindow(java.awt.Window root) { }

    public static TestProject getApplication() {
        return Application.getInstance(TestProject.class);
    }

    public static void main(String[] args) {
        launch(TestProject.class, args);
    }
}

AppView JFrame:

AppView JFrame:

import org.jdesktop.application.FrameView;
import org.jdesktop.application.SingleFrameApplication;

public class AppView extends FrameView {
   public AppView(SingleFrameApplication app) {
       super(app);

       JFrame mainFrame = TestProject.getApplication().getMainFrame();
       AboutBox newAboutBox = new  AboutBox();
       newAboutBox.setLocationRelativeTo(mainFrame);
       TestProject.getApplication().show(newAboutBox);
   }
}
