Hello everybody.
What's the best practice or more efficient way to deal, in D, with lots of
small objects? My problem is this: I have a small control, ListView. This
control can have hundreds (and theoretically thousands) of items
(ListViewItem instances, to be precise). And, in turn each o

Thanks bearophile.
With respect to passing structs as reference, I also have this problem. In
the widget, I have a opIndex method, that returns a ListViewItem given an
index (like an array). When opIndex return the instance I'm looking for,
and then I modify some property (a image index, fo

Thanks.

interface like
string opIndex(size_t item, size_t subItem);
string opIndexAssign(size_t item, size_t subItem, string newValue);
void sort(size_t subItem, bool asc=true);
which will be used by the control to present the

Instead of just giving you a link to the dlibs1, I've extracted the relevant
code and adapted it to D2:

I have tested it enough with D1 but only a bit with
Thanks bearophile. I'll give it a try later.
