Design view in Netbeans won't load

Question

I started to learn swing and downloaded netbeans to work through the tutorials. Unfortunately, when I create a JFrame design view hangs instead of loading and the Navigator and Inspector panes just show up empty.

System details:  
Linux Mint Maya
Netbeans version 7.0.1  
java 1.6.0_24

Any ideas would be greatly appreciated.

Answer 1

在您选择的任何编辑器/设计器中，请考虑此处显示的方法，其中手动创建顶级容器并在设计器中维护一个或多个内容面板。

Answer 2

查看 Netbeans View 菜单并选择“IDE log”那里可能有错误消息/异常，这可能会给你一个线索。

Answer 3

Reinstalling the nb-javac plugin fixed this issue for me.

I followed the steps here and it resolved my problem.

Answer 4

For me, this was caused by a "FormGuardedBlockError", because at one point in my project I copied all of the source out into Notepad++ and used that to replace the .java file, thereby stripping all of the //GEN-BEGIN and related directives.

You can close NetBeans, open the .java file in a plaintext editor and put these directives back by hand, but it may be easier to merge with an earlier version of your code (if you have one).

Answer 5

菜单->视图->显示编辑工具栏为我修复了这个问题，当然您选择编辑的文件必须有jframe，我认为添加到它以显示设计选项卡。

Answer 6

转到菜单 -> 选项 -> 从选项窗口工具中选择“Java”，然后选择“活动”
