I’m putting together a Swing application where I often want to replace the contents of a JPanel. To do this, I’m calling removeAll(), then adding my new content, then calling revalidate().
However I’m finding that the old content is still actually visible (though obscured by the the new content). If I add a call to repaint() in addition to revalidate(), it works as expected.
I’m sure on other occasions I’ve experienced that just calling revalidate() is enough.
So basically my question is – should I need to call both functions and if not, when should I call each of them?
