why is remove(myPanel2) not working?

[Geoff Cox]

Hello,

For some reason the

contentArea.remove(myPanel3);

works but the

contentArea.remove(myPanel2);

does not - any ideas please?

(happy to post the whole code if this helps)

Cheers

Geoff


if (textIndex == 0)
{


contentArea.remove(myPanel2);

contentArea.remove(myPanel3);
myPanel3 = new JPanel();
myPanel3.setBackground(Color.white);

JLabel endMessage = new JLabel("Thank you - all questions
answered");

myPanel3.add(endMessage);
contentArea.add(myPanel3, BorderLayout.SOUTH);
setContentPane(contentArea);
contentArea.setVisible(true);

}

[1] What do you mean 'it works'? *Specifically* what
do you mean? Describe it in detail, ..

...provide that code. Since the word
descriptions are not that clear.

E.G. you state that removing the myPanel3 'works', yet
your code immediately re-adds it, so I am not certain
how *you* can be sure it is *ever* removed in the first
place.

And look, for my personal preferences, the SSCCE[1] provided
with the brief explanation and question is almost always
necessary. *Especially* when the poster[2] has no idea what is
going wrong. The trick is that if the poster does not know
what is going wrong, they often (usually) post the wrong
'bit' of code.
