Struct FerroDialogsInternalViewModelBase 

pub struct FerroDialogsInternalViewModelBase { /* private fields */ }

The base of the view models of the dialogs: the property change notification and the helpers that raise it.

A view model embeds it (the base class of the managed original) and forwards INotifyPropertyChanged to it. The name of the property is passed explicitly where the managed original takes the name of the calling member.

Implementations

impl FerroDialogsInternalViewModelBase

pub fn new() -> Self

pub fn raise_and_set_if_changed<T: PartialEq>( &self, field: &RefCell<T>, value: T, property_name: &str, ) -> bool

RaiseAndSetIfChanged(ref field, value) for a Copy field.

pub fn raise_property_changed(&self, property_name: &str)

RaisePropertyChanged(propertyName).
