2 * anime_list.cpp: defines the anime list page | |
3 * and widgets. | |
4 * | |
5 * much of this file is based around | |
6 * Qt's original QTabWidget implementation, because | |
7 * I needed a somewhat native way to create a tabbed | |
8 * widget with only one subwidget that worked exactly | |
9 * like a native tabbed widget. | |
