Hi,
I had a problem when I using the tabbed pane in Java. I create a tabbed pane. I add a panel on it.
When I click the close button which is coded to remove the panel from the tabbed pane. It still appear the drawing on the screen. Even the component is really been removed.
So, I minimize the application and restore back it. It only will repaint or refresh the screen for me.
Any idea to overcome the problem?

Try repainting and revalidating the JTabbedPane

Code:

// create the tabbedpane and add a panel
JPanel panel = new JPanel();
JTabbedPane jtp = new JTabbedPane();
jtp.addTab("Panel", panel);

// remove the panel
jtp.remove(panel);
jtp.repaint();
jtp.revalidate();

Yeah the result still remain the same. Still can't make it repaint or refresh.
It only work sometimes. Depends on luck.

try revalidate before repaint to see if it is better

It still the same. I try with

remove(jtp);
add(jtp);

it still same.

i have run into some weird repaint issues before as well. its probably because i do not know the *right* way to do it, and what i do is probably cheating a bit. what i would do, that would work for sure, is to toggle the visibility of the component. do a

Code:

setVisible(false);
setVisible(true);

this will guarantee a repaint.

At last I know what the problem. You use any other library file for tabbedPane beside from Sun Java itself?
I use the 3rd party library file it got problem. after I use bak the original library file from Sun, it seems like no problem.
And I try your cheating skill. Haha it can't work for me. I better use back the original library file from Sun Java.
