Struct WhenBuildAction

pub struct WhenBuildAction {
    pub data: Arc<dyn Any + Send + Sync>,
    pub default_action: Option<Arc<dyn Fn() -> Vec<Box<dyn AnyPropertyBuildAction>> + Send + Sync>>,
}

Data for a custom when build action associated with an WhenInfo.

Fields

data: Arc<dyn Any + Send + Sync>

Data for all inputs.

default_action: Option<Arc<dyn Fn() -> Vec<Box<dyn AnyPropertyBuildAction>> + Send + Sync>>

Closure that generates the default build actions, used when the final widget has no build action instance.

The closure must generate an action that behaves like it is not present and then activates when the condition data activates.

If the final widget has no action and all when data for it has no default, the data is ignored.

Implementations

impl WhenBuildAction

pub fn new<D, F>(data: D, default_action: F) -> Self

where D: Any + Send + Sync + 'static, F: Fn() -> Vec<Box<dyn AnyPropertyBuildAction>> + Send + Sync + 'static,

New from strongly typed values.

pub fn new_no_default(data: impl Any + Send + Sync + 'static) -> Self

New from data, is only used if the action is provided by another data or the widget builder.
