[−][src]Struct druid::widget::Either
A widget that switches between two possible child views.
Implementations
impl<T> Either<T>[src]
pub fn new(
closure: impl Fn(&T, &Env) -> bool + 'static,
true_branch: impl Widget<T> + 'static,
false_branch: impl Widget<T> + 'static
) -> Either<T>[src]
closure: impl Fn(&T, &Env) -> bool + 'static,
true_branch: impl Widget<T> + 'static,
false_branch: impl Widget<T> + 'static
) -> Either<T>
Create a new widget that switches between two views.
The given closure is evaluated on data change. If its value is true, then
the true_branch widget is shown, otherwise false_branch.
