Enum druid::widget::LabelText

pub enum LabelText<T> {
    Localized(LocalizedString<T>),
    Static(Static),
    Dynamic(Dynamic<T>),
}

The text for a Label.

This can be one of three things; either an ArcStr, a LocalizedString, or a closure with the signature Fn(&T, &Env) -> impl Into<ArcStr>, where T is the Data at this point in the tree.

Variants

Localized(LocalizedString<T>)

Localized string that will be resolved through Env.

Static(Static)

Static text.

Dynamic(Dynamic<T>)

The provided closure is called on update, and its return value is used as the text for the label.

Implementations

impl<T: Data> LabelText<T>

pub fn with_display_text<V>(&self, cb: impl FnMut(&str) -> V) -> V

Call callback with the text that should be displayed.

pub fn display_text(&self) -> ArcStr

Return the current resolved text.

pub fn resolve(&mut self, data: &T, env: &Env) -> bool

Update the localization, if necessary. This ensures that localized strings are up to date.

Returns true if the string has changed.
