[AI-CS5] Unable to capture panel closed/Hide event .

Question

Hi All,
I am using  flex for  my illustrator plug-in panel. I want to show a msg if panel is closed.
I registered  StateChangeEvent.WINDOW_CLOSE /StateChangeEvent.WINDOW_HIDE in PanelInit() but I am unable to get the call.
here is the code that i am using to register.
CSXSInterface.getInstance().addEventListener(StateChangeEvent.WINDOW_CLOSE , PanelClose);
CSXSInterface.getInstance().addEventListener(StateChangeEvent.WINDOW_HIDE , PanelHide);
however in case of StateChangeEvent.WINDOW_CLOSE I am getting call only if illustrator is being closed and panel is opened.
plz suggest how to overcome?
thanks
R.

I believe this is a bug in Illustrator CS5. Because panels are only hidden (rather than truly closed) when the user clicks to close them, the close event does not fire. I think this is unique to Illustrator and it should be fixed for CS6.
In the meantime there is this slightly ugly workaround, where you can set up a timer to intermittently poll the visible property of a window, which accurately reflects whether the panel window is visible (unlike the closed property, which as you have noted remains 'false' until Illustrator itself is closing).
