在NetBeans GUI Designer中重用JPanel [英] Reusing a JPanel in NetBeans GUI Designer

问题描述

这是在NetBeans 6.5，Java 6中。

This is in NetBeans 6.5, Java 6.

我在NetBeans GUI Designer中有以下层次结构：

I have the following hierarchy in the NetBeans GUI Designer:

JFrame
  JTabbedPane
    JPanel X
      <...>
    JPanel
      JButton
      JPanel Y
        <...>
      JButton

问题：

JPanel Y与JPanel X相同，所以我想在两个地方重复使用JPanel X，但是如何在GUI Builder中执行此操作？

Question:

JPanel Y is identical to JPanel X, so I'd like to simply reuse JPanel X in both places, but how do I do this inside the GUI Builder?

我尝试复制粘贴JPanel X，但它创建了一个完整的深度副本（JPanel X1等），复制了JPanel X中的所有内容。

I tried copy-pasting JPanel X, but it creates a full "deep" copy (JPanel X1, etc), duplicating everything in JPanel X.

一些谷歌搜索表明可以将它添加到Palette中，但我还没有找到一种方法将简单的JPanel添加到调色板（而不是完整的JFrame）。

Some googling indicated it might be possible to add it to the Palette, but I haven't found a way to add a simple JPanel to the palette (as opposed to a complete JFrame).

推荐答案

创建一个单独的JPanel类。根据需要自定义JPanel。然后，您可以将JPanel类拖放到表单设计器上。这正是我所做的。

Create a separate JPanel class. Customize JPanel as needed. You can then drag-and-drop the JPanel class onto the Form Designer. This is exactly what I do.

或者，您可以单击使用Bean，然后键入类的名称。

Alternatively, you can click on Use Bean and then type in the name of the class.

或者，您可以从托盘中执行添加，它将扫描您的JAR以查找任何bean。它也应该选择你的自定义JPanel。

Alternatively, you can do an Add from the pallete and it will scan your JAR for any "beans". It should pick up your custom JPanel as well.
