Hello,

I have an application that uses a JDesktopPane, with a menubar
and several opened JInternalFrames, some of them partly covering
the visible surface of another.

I can bring to front each of them and the JDesktopPane and
all frames will be repainted correctly.

But if I open a JDialog, to get some user input, the JDesktopPane and
all frames will NOT be repainted once I close the JDialog, i.e. a big
grey surface remains on the screen where the JDialog was.

First I tried to add

System.out.println("a");
desktopPane.revalidate();
desktopPane.repaint();
System.out.println("b");

after the JDialog is closed but this doesn't seem to have an impact.
I can see the "a" and the "b" in the output, hence the revalidate and
paint should have been issued.

Next I tried to revalidate and repaint all the open frames with:

JInternalFrame[] frames = desktopPane.getAllFrames();
for(int i=0; i < frames.length; ++i)
{
frames[i].revalidate();
frames[i].repaint();
};

but this does not update the screen either.

The only thing that works is

JInternalFrame[] frames = desktopPane.getAllFrames();
for(int i=0; i < frames.length; ++i)
{
frames[i].toFront();
};

But this is not very "nice" as it brings to front unecessary windows.
I can of course program it bit smarter so that only internalframes
with visible parts are put to front, but I guess there must be a simpler
way?

any ideas?

thanks in advance!
