Question

I already look at java library and dont know what to use to do this..
I already tryed JInternalFrame but thats not what I really want.. because it needs to be added to a JDesktopPanel right??

And in my program I have a JFrame with content pane using BorderLayout..
Then on borderlayout center I have a JTextArea, on borderlayout east I have a list.. and on borderlayout south I have a JPanel..

What I want is, when I do a certain action, it will pop up a “mini window” where I need to choose something.. u see?
and if I create JDesktopLane it will overlap what I have on the container..

the window will be made by my like a color chooser pallete , like a grid with colors.. and a label on top saying some text..

I just dont know how to make a “window” over the other components, and users can still drag over the frame, and interact with all the other components.. the jtextarea and such..

I guess you understood, thanks alot in advance!!
If u dont understand something please tell me, I really want to do this 🙂
Just dont know what to use..

Thanks again 😉

Answer 1

The typical class for this task is JWindow, a borderless top-level window that can be freely positioned. You could use SwingUtilities.getPointFromComponent to get the screen coordinates for a realized coordinate.

Top-level windows (JFrame, JDialog, JWindow) are not added to containers. They can get other windows as parent.

I dont want to use another JFrame.. that is kinda bad for code, its a small window with a simple function..

Structure your code so you can read it, others can read it, and you can debug it easily (the latter is a result from the first). A low class count is useless and -most of the time- contraproductive.

Why should another JFrame (or other window) be bad?

If you absolutely want to avoid opening top level windows (e.g. to avoid applet warning icons or to implement a special kind of user interface) you could use a JLayeredPane to add additional JPanels above your existing GUI elements.
