Does this work? If this was a variable this surely wouldn't work,
because it's scope would be local to the procedure.

How can I tell when my application has loaded and I can start
initializing some of the form elements?
At the moment I place all of the initialization routines in the

There is a flaw in the code suggested below. To accomplish what you seem to
want, the SHOWED_FIRST_TIME variable needs to be an instance variable rather
than a local variable as declared below.
That is, the SHOWED_FIRST_TIME variable should be declared in the class
definition of the form.
No, there's no problem. A typed constant is allocated just like a
global variable (or a static local variable in C).
The syntax is hackish, but the functionality is nice, indeed.
