    Do you have a question associated with this? What do you expect to happen, with what components?

    For future reference, please post an SSCCE, and please use the code tags. I recommend editing your post and flanking the source code with [highlight=java]Your Code Here[/highlight]

    Default Re: Im trying to open a new GUI window by clicking on a button

    What I am asking is how do I display the buttons and panel in the new window. I can't seem to display it even though I've added and delcared it in the method detailView()
