java - 如何将 JWindow 添加到 NetBeans 项目并使用 GUI 编辑器对其进行编辑？

Question

只有一个选项可以将 JFrame 和 JPanel 添加到项目中。我尝试编辑 JFrame 类来扩展 JWindow，但它使 NetBeans 的自动生成代码出现错误，并且无法编辑此代码。

Answer 1

您可以创建自己的模板...

将这两个文件放在...\NetBeans\7.2.1\config\Templates\GUIForms文件夹中。

在 Windows 7 上C:\Users\{your user name}\AppData\Roaming\NetBeans\7.2.1\config\Templates\GUIForms

JWindow.java

<#assign licensePrefix = " * ">
<#assign licenseLast = " */">
<#include "../Licenses/license-${project.license}.txt">

<#if package?? && package != "">
package ${package};

</#if>
