/* As far as I can tell, the submenu hierarchy looks like this:
|
|
*
|
|
* The DeskBar's Child is the Band it contains.
|
|
* The DeskBar's Parent is the SID_SMenuPopup of the Site.
|
|
*
|
|
* The Band's Child is the IMenuPopup of the child submenu.
|
|
* The Band's Parent is the SID_SMenuPopup of the Site (the DeskBar).
|
|
*
|
|
* When the DeskBar receives a selection event:
|
|
* If it requires closing the window, it will notify the Child (Band) using CancelLevel.
|
|
* If it has to spread upwards (everything but CancelLevel), it will notify the Parent.
|
|
*
|
|
* When the Band receives a selection event, this is where it gets fuzzy:
|
|
* In which cases does it call the Parent? Probably not CancelLevel.
|
|
* In which cases does it call the Child?
|
|
* How does it react to calls?
