秋千上的外部面板

Question

I have something like this...

Its a bunch of JLabels within JPanels inside a

--JFrame

--JPanel

    --Set<JPanel>
        --JLabel object contained in each JPanel object cotained in the set

I want to create an external panel/frame so that each time I hover over each individual JPanel, a new frame/panel pops up giving me some data. This will essentially overlap over the JFrame.

Its pretty brief but I just need some guidance as to what I need to look up.

Answer 1

Maybe you can just use JToolTip. When the mouse hovers over the label for a couple of seconds it will display automatically. See the section from the Swing tutorial on How to Use Tool Tips .

Or if you want something more complicated use a MouseListener. On mouseEntered() you can display a JPopupMenu or an undecorated JDialog .

You can start by reading the Swing tutorial on How to Write a Mouse Listener .
