How to program toggle-able JPanels?
April 10, 2006 12:32 PM
Java question: how to program a toggle-view in a GUI?
Basically, I want to have two seperate JPanels that are the same size and occupy the same space in the frame, but only allow one to be visible at any time, so that the view can be toggled in between these two panels with a radio button. Using the glass pane seems to be out because it covers the menu bar, and I've had absolutely zero luck with getting the layered pane to work out, so I'm kind of stuck. Any help would be appreciated!

There is actually a container that can be used to do this, supposedly. It's like a tabbed component, but without the tabs.

A JLayeredPane might do what you want. So you would have something like:
1) you're main window/frame/whatever
1.A) your checkboxes
1.B) A JLayeredPane
1.B.a) Panel one
1.B.b) Panel two

Oops, looks like you already tried a layered pane.
The next step IMO, would be to simply have two panes. When you want to show one, remove the other one (if it's there) and then add this one to another sub-pane. Continue to swap them out as needed. I've never tried anything like that, though.

You want something like the CardLayout or CardPanel.
I don't believe the JLayeredPane is intended to be used for card layouts; it's mostly for when you need greater control over the z ordering, i.e. when you have components floating over one anthoer.

Ah, I was thinking of CardLayout, but I couldn't find it in swing, it's part of the old AWT.

Metafilter eats all the nbsps in the composition box as soon as you do a preview. I work around this by composing anything with nbsps in an external editor, then doing paste - preview - paste - post.

1. Make a JPanel to hold the 2 subpanels and set its size.
2. Create the 2 sub JPanels and set their preferred sizes.
3. Write a custom LayoutManager to position the 2 sub panels on the parent panel at the correct location.
4. Call panel.setVisible(false) on the first sub panel and panel.setVisible(true) on the other
5. Code the event handler for your radio buttons to set the visibilty on the sub panels correctly
You shouldn't need any class panes or anything- just the setVisible() function and tha ability to do your own layout.
