    Default Renaming labels & text boxes

    Iíve started to create a GUI that consists of a few tabs. Right now I am focusing on two of them. The Pool tab and the Hot Tub tab. When I first started I got everything to work fine on the pool tab. So I figured since all of the label and text box placement would be the same for the Hot Tub tab I would just copy the coding over. Well, I did that and tried naming all the labels and text boxes the same just with the number 2 after them. Itís not working. Now the Hot Tub tab works, but the Pool tab doesnít, plus the text boxes are gone. Iím also having alignment issues with the text boxes too, but I think that has to do with the naming of the labels and text boxes, Iím not sure. I know the code is kind of long, but Iím just concentrating on the pool and hot tub tabs.

    Default Re: Renaming labels & text boxes

    Define "its not working". Just from quickly inspecting your code, I'd highly recommend using a LayoutManager rather than a null layout. See A Visual Guide to Layout Managers (The Javaô Tutorials > Creating a GUI With JFC/Swing > Laying Out Components Within a Container)
