API 文档由 Go 源码生成，内容为英文。

type MenubarState ui.ID

MenubarState is caller-owned top-level popup state. Its zero value is closed; a nonzero value is the stable ID of the active trigger.

构造函数

MenubarHover#

func MenubarHover(state MenubarState, trigger ui.ID, now time.Time, intent *HoverIntent, delay time.Duration) (MenubarState, time.Duration)

MenubarHover advances the menubar's hover switch: while a menu is open, resting on another trigger opens that trigger's menu after delay. With no open menu, or with the pointer on the open trigger, it does nothing. It returns the state and the wait before asking again.

MenubarKeyDown#

func MenubarKeyDown(current ui.ID, triggers []MenubarTrigger, open MenubarState, direction Direction, key ui.Key) (MenubarState, ui.ID, bool)

MenubarKeyDown moves the menubar's keyboard focus and, while a menu is open, switches the open menu with it. Left and Right move between triggers with wrapping (reversed in RTL), Home and End go to the ends, Down/Enter/Space open the focused trigger, and Escape closes the open menu and returns to its trigger. Items inside the open menu are the caller's to focus after an open.
