Struct ViewLocator 

pub struct ViewLocator { /* private fields */ }

Builds the view of a view model: the class whose full name is the full name of the class of the view model with ViewModel replaced by View.

Implementations

impl ViewLocator

pub fn new() -> Rc<ViewLocator>

pub fn as_data_template(&self) -> Rc<dyn IDataTemplate>

The locator as the data template contract.

Trait Implementations

impl IDataTemplate for ViewLocator

fn match_(&self, data: Option<&BoxedValue>) -> bool

Checks to see if this data template matches the specified data.

fn as_any(&self) -> Option<&dyn Any>

The implementing value, for casting to its concrete type (as_any()?.downcast_ref::<T>()): the equivalent of is/as on the contract. None for an implementation that does not expose itself.

fn as_recycling_data_template(&self) -> Option<&dyn IRecyclingDataTemplate>

The template viewed as a recycling data template, if it is one.

fn as_typed_data_template(&self) -> Option<&dyn ITypedDataTemplate>

The template viewed as a typed data template, if it is one.

fn as_tree_data_template(&self) -> Option<&dyn ITreeDataTemplate>

The template viewed as a tree data template, if it is one.

impl IRecyclingDataTemplate for ViewLocator

Deviation (DEVIATIONS.md, Developer tools): the locator is a recycling data template. The view it built last for a content is reused for the next view model of the same view, which gets it as its data context, where upstream builds a new view for every view model: the details of a control are a new view model at every selection of a node, and building their view again (the property grid with its columns, rows and editors, the layout, the value frames) made the properties appear a moment after the selection. The views follow their data context.

fn build_with_existing( &self, data: Option<&BoxedValue>, existing: Option<Ref<Control>>, ) -> Option<Ref<Control>>

Creates or recycles a control to display the specified data.

impl ITemplateWithParam<Option<Rc<dyn AnyValue>>, Option<Ref<Control>>> for ViewLocator

fn build(&self, data: &Option<BoxedValue>) -> Option<Ref<Control>>

Creates the control.

impl MarkupTyped for ViewLocator

const MARKUP: &'static MarkupType

The markup metadata of the type.

impl PartialEq for ViewLocator

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
