Required Methods

fn new_edit_data( &self, ctx: &Self::Context<'_>, ) -> Result<Self::Data, Self::Err>

Create default data.

fn set_edit_data( &mut self, data: &Self::Data, ctx: &Self::Context<'_>, ) -> Result<(), Self::Err>

Set editing data.

fn get_edit_data( &mut self, data: &mut Self::Data, ctx: &Self::Context<'_>, ) -> Result<(), Self::Err>
