Hello,

I have a JTabbedPane with several tabs on it.  Each tab has a panel with
components that a user will be using to enter and view data.  On one of my
tabs, a user can initiate a process to create a new "widget".  I want to
make it so that if a user initiates that process, but decides to switch to
another tab before hitting a "confirm" button, a JDialogBox will be
displayed to the user (before showing the tab they're trying to click on)
informing them that they didn't confirm their change and that if they leave,
they'll lose all of their changes.

I plan on using a "dirty" flag to track whether or not they tried to
initiate the new widget process.  However, I don't know how to go about
tracking when they try to leave this tab and firing off the JDialogBox
BEFORE showing the other tab they're trying to switch to (I don't care if
they're just switching between different windows applications).  Can anyone
give me any pointers or suggestions how to go about this?  Thanks in
advance.

Jeff
