29 * @class KToolBarPopupAction ktoolbarpopupaction.h KToolBarPopupAction
30 *
31 * This action is a normal action everywhere, except in a toolbar
32 * where it also has a popupmenu (optionally delayed). This action is designed
33 * for history actions (back/forward, undo/redo) and for any other action
34 * that has more detail in a toolbar than in a menu (e.g. tool chooser
35 * with "Other" leading to a dialog...).
36 *
37 * In contrast to KActionMenu, this action is a \e simple menuitem when plugged
38 * into a menu, and has a popup only in a toolbar.
39 *
40 * Use cases include Back/Forward, and Undo/Redo. Simple click is what's most commonly
41 * used, and enough for menus, but in toolbars there is \e also an optional popup
42 * to go back N steps or undo N steps.
43 *
44 * @note Add actions to the popupMenu(), don't use setMenu().
