/**
 * @page pattern_dlg_pattern Pattern Selection Dialog
 *
 * The Pattern Selection Dialog lets the user select a pattern.
 *
 * This is a @ref gui_simple
 *
 * ## Windows
 *
 * | Name                     | Type           | See Also      |
 * | :----------------------- | :------------- | :------------ |
 * | Pattern Selection Dialog | WT_DLG_PATTERN | dlg_pattern() |
 *
 * **Parent**
 * - @ref gui_dialog
 *
 * **Children**
 * - See: @ref gui_simple
 *
 * ## Data
 * - #Menu
 * - #Menu::mdata
 * - #PatternEntry
 *
 * The @ref gui_simple holds a Menu.  The Pattern Selection Dialog stores its
 * data (#PatternEntry) in Menu::mdata.
 *
 * ## Events
 *
 * Once constructed, it is controlled by the following events:
 *
 * | Event Type  | Handler                   |
 * | :---------- | :------------------------ |
 * | #NT_CONFIG  | pattern_config_observer() |
 * | #NT_WINDOW  | pattern_window_observer() |
 *
 * The Pattern Selection Dialog doesn't have any specific colours, so it
 * doesn't need to support #NT_COLOR.
 *
 * The Pattern Selection Dialog does not implement MuttWindow::recalc() or
 * MuttWindow::repaint().
 *
 * Some other events are handled by the @ref gui_simple.
