Hi James,
The easiest way I can think of, if the menu itself is not dynamic, is a)
include the header for the class that has the menu in the implementation
file for the window class that you want to respond to when it is closing, b)
add an event handler to the window that is closing for the OnClose event, c)
add code to the handler that sets the checked state of the relevant menu
item appropriately (which is why you want the header file for the window
that has the menu included - so you have access to the relevant menu item -
when BCB adds these controls, they are added as published properties), or
you can add a public inline function to the main window which is invoked by
the child window when it is closed, which effectively does the same thing.

Cheers,

Ted
