The partial methods of CompositionLinearGradientBrush: implemented by the class that embeds CompositionLinearGradientBrushProps. Every hook defaults to doing nothing.

Required Methods

fn base_serialize_changes_core(&self, writer: &mut BatchStreamWriter<'_>)

base.SerializeChangesCore(writer): serializes the changes of the hand-written base class CompositionGradientBrush.

Provided Methods

fn initialize_defaults_extra(&self)

fn validate_start_point_change( &self, _old_value: RelativePoint, _new_value: RelativePoint, )

fn on_start_point_changed(&self)

fn on_start_point_changing(&self)

fn validate_end_point_change( &self, _old_value: RelativePoint, _new_value: RelativePoint, )

fn on_end_point_changed(&self)

fn on_end_point_changing(&self)

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
