Hi,
I am developing a program where I use JInternalFrame(s). In each of the
JInternalFrame(s) I have a text field that is updated every now and then.
If the JInternalFrame is minimized, is there a way to make the iconized
JInternalFrame blink when its contents is changed?

Thanks in advance
Koko

One untested idea: Try to activate or deactivate it cyclically.

I'd say that you should take a look at the DesktopManager interface, and
the Default implementation. A couple of things come to mind:

1. If you have maximized JInternalFrames, flashing the icon is not going
to make any difference, because it won't be visible. Similarly if you
have JInternalFrames arranged on top of the icons, even if they are not
maximised.

2. You may want to consider implementing a "task bar"-like
DesktopManager, (maybe even a JToolBar?) which prevents the windows from
maximising to cover the task bar. You could implement a JButton in the
taskBar to activate/iconify each of the JInternalFrames. Since you are
controlling the JToolBar and the buttons yourself, it would be a simple
matter to change the colour of the button to make it flash.

3. For the above to work properly, you'd have to prevent the iconified
JInternalFrames from being shown on the JDesktopPane. The DesktopManager
class might help you here.

Alternatively, you might want to try playing with the
set/getDesktopIcon() methods. By "inverting" and "reverting" the
background and foreground colours of this Component, you should be able
to make it flash, I think.

Note that the docs suggest that you should not depend on this API, as it
should be subsumed into JInternalFrame eventually . . .
