示例1: make_item_list
void inventory_selector::make_item_list(const indexed_invslice &slice, const item_category *def_cat)
{
for( const auto &scit : slice ) {
// That entry represents the item stack
const itemstack_or_category item_entry(scit);
const item_category *category = def_cat;
if (category == NULL) {
category = item_entry.category;
}
// Entry that represents the category header
const itemstack_or_category cat_entry(category);
itemstack_vector::iterator cat_iter = std::find(items.begin(), items.end(), cat_entry);
if (cat_iter == items.end()) {
// Category is not yet contained in the list, add it to the end
items.push_back(cat_entry);
cat_iter = items.end();
} else {
// Category is already contained, skip all the items that belong to the
// category to insert the current item behind them (but before the next category)
do {
++cat_iter;
} while(cat_iter != items.end() && cat_iter->it != NULL);
}
items.insert(cat_iter, item_entry);
}
}示例2: prepare_paging
void inventory_selector::prepare_paging(itemstack_vector &items)
{
const item_category *prev_category = NULL;
for (size_t a = 0; a < items.size(); a++) {
const itemstack_or_category &cur_entry = items[a];
if (cur_entry.category != NULL) {
prev_category = cur_entry.category;
}
if (cur_entry.it == NULL && a % items_per_page == items_per_page - 1) {
// last entry on a page is a category, insert empty entry
// to move category header to next page
items.insert(items.begin() + a, itemstack_or_category());
continue;
}
if (cur_entry.it != NULL && a > 0 && a % items_per_page == 0) {
// first entry on a page and is not a category, insert previous category
items.insert(items.begin() + a, itemstack_or_category(prev_category));
continue;
}
}
