NetBeans jFrames无法正常显示（只显示正在加载...） [英] NetBeans jFrames not working (just showing loading...)

问题描述

我在Netbeans IDE 7.0.1中创建了一个新项目。在那个项目中，我创建了一个新的 JFrame 表单。但是该框架未加载。

I created a new project in Netbeans IDE 7.0.1. In that project I created a new JFrame form. But that frame is not loading.

然后我试图运行该程序，它有以下例外：

Then I tried to run the program anyway and it gave the following exceptions:

推荐答案

看起来您必须将 Swing布局扩展程序库添加到您的项目中，浏览器，请右键单击库> 添加库... ，然后选择 Swing布局扩展程序库。问题已解决。

Looks like you have to add the Swing Layout Extensions Library to your project, to do so go to the Projects explorer, do right-click on Libraries > Add Library... and select Swing Layout Extensions Library. Problem solved.

这是从 NetBeans jFrames不起作用
