Struct RootWidget

pub struct RootWidget<RootElem: Element<NoEvent, ()> + Clone + 'static> {
    pub root_element: RootElem,
    pub root_state: RootElem::AggregateChildrenState,
    pub vdom: Option<RootElem::BuildOutput>,
    pub default_widget: WidgetPod<DruidAppData, Flex<DruidAppData>>,
    pub widget: Option<WidgetPod<DruidAppData, FlexWidget<<<RootElem as Element<NoEvent, ()>>::BuildOutput as VirtualDom<NoEvent, ()>>::TargetWidgetSeq>>>,
}

Implements druid::Widget from a component

You should probably use RootHandler directly instead.

Fields

root_element: RootElem

root_state: RootElem::AggregateChildrenState

default_widget: WidgetPod<DruidAppData, Flex<DruidAppData>>

widget: Option<WidgetPod<DruidAppData, FlexWidget<<<RootElem as Element<NoEvent, ()>>::BuildOutput as VirtualDom<NoEvent, ()>>::TargetWidgetSeq>>>
