How restore the panel in the design view of Jframe in netbeans java?

Question

我在netbeans java的Jframe的设计视图中遇到问题。我未选中Jframe中面板的可见属性，但该面板未在设计视图中看到。我想将面板重新放入设计视图本身的框架中请帮我解决这个问题。

Answer 1

I suggest creating another project where panel is visible and comparing the code between the two projects. Try to be creative and figure out these kinds of problems on your own, you will benefit more than you can now imagine.

Answer 2

Changing opaque property of jpanel,you might make it invisible.If the issue is that; In design view you can see Navigator Panel bottom left side.You can see all of components you have created in here.For solving the issue

Navigator Panel->find your jPanel ->Right Click->Properties Window->Check Opaque Property
