[Gambas-user] Keeping track of opened form instances

[Bruce]

Hi folks,

I have a form ("FSummary") that basically opens a variable number of
other forms. This action is controlled by the user.

Each other form is an instance of a single form/class, say "FDetail".
Each and any of these could be closed by the user at any time.  Also,
when the FSummary form is closed, any remaining FDetail forms need to be
automatically closed.

I have tried a few times to achieve this using arrays of Forms and
arrays of window handles etc. but I am not really happy with the
results.

How have others approached this issue?
