I’ve created JPanel and have already added components into it and I’m going to pass that JPanel to PopUpFactory… So can I get size of JPanel before passing it?
I put Jlabel into it and text after that and I don’t know the size of that text…
Just call getPreferredSize method for JLabel.No matter if container of it is not realized, preferred size changes if you are setting text of jlabel even before you set it visible.
