Struct zng_wgt::EDITORS

pub struct EDITORS;

Service that provides editor widgets for a given variable.

Auto generating widgets such as a settings list or a properties list can use this service to instantiate widgets for each item.

The main crate registers some common editors.

Implementations

impl EDITORS

pub fn register(&self, editor: WidgetFn<EditorRequestArgs>)

Register an editor handler.

The handler must return NilUiNode if it cannot handle the request. Later added handlers are called first.

pub fn register_fallback(&self, editor: WidgetFn<EditorRequestArgs>)

Register an editor handler to be called if none of the register editors can handle the value.

The handler must return NilUiNode if it cannot handle the request. Later added handlers are called last.

pub fn get(&self, value: impl AnyVar) -> BoxedUiNode

Instantiate an editor for the value.

Returns NilUiNode if no registered editor can handle the value type.

pub fn req<T: VarValue>(&self, value: impl Var<T>) -> BoxedUiNode

Same as get, but also logs an error is there are no available editor for the type.
