Struct zng_app::widget::node::WhenUiNodeListBuilder
source · pub struct WhenUiNodeListBuilder { /* private fields */ }Expand description

When the selected list changes the previous one is deinited and the new one is inited.
Implementations§
source§impl WhenUiNodeListBuilder
impl WhenUiNodeListBuilder
sourcepub fn new(default: impl UiNodeList) -> Self
pub fn new(default: impl UiNodeList) -> Self
New with list that is used when no condition is active.
sourcepub fn push(&mut self, condition: impl Var<bool>, list: impl UiNodeList)
pub fn push(&mut self, condition: impl Var<bool>, list: impl UiNodeList)
Push a conditional list.
When condition is true and no previous inserted condition is true the list is used.
sourcepub fn build(self) -> impl UiNodeList
pub fn build(self) -> impl UiNodeList
Build a list that is always the first true condition or the default.
