Deriving my own group-object from TppGroups

rbuser

Hi,

I want to change the behaviour of the TppGroups, so that it will only print
groupheaders and footers in certain conditions.
I don't like to change the RB sourcecode of course, but inheriting rom TppGroups
is made very difficult as there are only a few methods and functions that
are declared virtual!

I would esp like the function CheckFroBreak and ForceBreak to be virtual
so i can override them.

Are there any plans on broadening the number of virtual functions, or does
anybody know an alternative way for achieving this?

One possible approach for controlling group header/footer visibility is to
implemnent event-handlers for each band.BeforePrint event to toggle the
band's Visible property.

It is not currently possible to create band or group descendants. Those are
a couple of areas of the product that cannot be extended.

It is possible to create component descendants (descend from Printable,
Component, Stretchable, etc).

As a side note, we do from time to time re-declare methods as virtual in
response to customer requests.
