I have been writing a small suite of wimp applications recently, and came
across an annoying feature of the wimp messaging system. When a program
receives a Message_PreQuit, the PRMs say...
'Note that if the user subsequently selects OK (...) the task must restart
the closedown sequence by issuing a key-pressed-event (Ctrl-Shift-F12) to the
task which send it the PreQuit message.'
This is all fine and dandy if you select Exit from the Switcher icon, as
it sends you a prequit and then a quit message. If you quit a task from the
Task Display however, it also gets a prequit message from the Task Manager.
Subsequently, if it follows recommendations, it tells the Task Manager that
someone has just hit Ctrl-Shift-F12, and the whole Desktop starts closing
down. Currently, I just completely ignore the recommendation to restart the
closedown sequence... Are there any new guidelines on what should be done,
as this is very silly, but it's always polite to do what the book says...
(It is very obvious if you load Edit, change a document, choose quit Edit
from the Task Display, and say no you don't want to save)...
