Pretty much yes, but in a class wrapper. You can add and remove items,
iterate through them etc. Maybe you can derive a class from TList to
customize it a bit.
There are two things to think of:
- you yourself have to make sure that elements are properly freed, so
when deleting object A, get a reference to it, delete it from the list,
and then free the object. (however that can be automized in the class
warpper)
- The internal list has two counters, instead of just "nNicks". One
(capacity) is the reserved space, the other (count) is the amount of
elements filled. This avoids too many memory fragmenting reallocs.
(but that's better, not worse)
I learned to use the classes from code snippets written for Delphi.
There is FCL documentation somewhere (and it will be in the next full
release), but I couldn't find a recent version so fast.
So I put down a very old version (April 2002) on the web here:
www.stack.nl/~marcov/fcl.pdf
it at least describes the tlist methods.
