Java JTabbedPane allow Tab to switch to only if true?

You can use the method tab. SetEnabledAt(index, false) to disable the tab if validation = false, and tab. SetEnabledAt(index, true) to turn it back on when validation = true.

Try override JTabbedPane. SetSelectedIndex(int index).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
