Struct AnyTooltip

Source

pub struct AnyTooltip {
    pub view: AnyView,
    pub mouse_position: Point<Pixels>,
    pub check_visible_and_update: Rc<dyn Fn(Bounds<Pixels>, &mut Window, &mut App) -> bool>,
}

Expand description

重导出 App 核心模块（App、Context、Entity、EntityId 等）包含与工具提示关联的状态。仅当在自定义元素上实现工具提示行为时才需要此结构体。否则，请使用 Div::tooltip。

Fields§

§view: AnyView

用于显示工具提示的视图

§mouse_position: Point<Pixels>

工具提示展开时鼠标的绝对位置。

§check_visible_and_update: Rc<dyn Fn(Bounds<Pixels>, &mut Window, &mut App) -> bool>

根据工具提示的边界检查工具提示是否仍应可见，并相应地更新其状态。这需要在悬停元素的鼠标移动处理程序之上，以处理元素未被绘制的情况（例如通过使用 visible_on_hover）。
