Revalidate and repaint - Java Swing
- by bosra
I have a JPanel that I am adding JLabel's to. I then want to remove all the JLabels and add some new ones.
So I do the following:
panel.removeAll();panel.repaint();
panel.add(new JLabel("Add something new");
panel.revalidate();
This works fine. My problem arises when I start a new thread after this like:
panel.removeAll();panel.repaint();
(1)panel.add(new JLabel("Add something new");
panel.revalidate();
//new thread to start - this thread creates new JLabels that should appear under (1)
firstProducer.start();
try {
firstProducer.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Then the output from the original JLabels is still visible. I have read that the revalidate process is a long running task and hence the firstProducer thread is getting started while
the revalidation is going on and a conflict is arising. What is the best way to deal with this?
