Can anyone offer some guidance on when exactly to call this?
My docs say
".. If you rearrange the widgets in your group, call this method to register
the new arrangement with the Fl_Group that contains them."
So, for instance, suppose I do something like this:
// Make room for a new thing and prepend it.
Thing* thing = new Thing(x, y, w, h);
for(int k = 0; k < my_group->children(); ++k) {
my_group->child(k)->position(
my_group->child(k)->x(),
my_group->child(k)->y() + thing->h()
);
}
my_group->insert(*thing, 0);
Am I supposed to call my_group->init_sizes() before the loop?
After the loop? Inside the loop? After the insert? Never?
The fact is, I haven't been able to detect any difference.. any
advice?
Thanks,
Stan
