Trait agui::widget::WidgetBuilder [−][src]
pub trait WidgetBuilder: Downcast {
fn build(&self, ctx: &WidgetContext<'_>) -> BuildResult;
}Expand description
Implements the widget’s build() method.
Required methods
fn build(&self, ctx: &WidgetContext<'_>) -> BuildResult
fn build(&self, ctx: &WidgetContext<'_>) -> BuildResult
Called whenever this widget is rebuilt.
This method may be called when any parent is rebuilt, when its internal state changes, when global state changes, when a computed function changes, or just because it feels like it. Hence, it should not be relied on for any reason other than to return child widgets.
