Trait for the editor widget state.

Required Associated Types

type Context<'a>

Some external context.

type Err

Error type.

Required Methods

fn create_value<'a>(&self, ctx: &'a Self::Context<'a>) -> Result<T, Self::Err>

Create a fresh row value with all the defaults.

fn set_value<'a>( &mut self, value: T, ctx: &'a Self::Context<'a>, ) -> Result<(), Self::Err>

Set the current row value for the editor.

fn value<'a>( &mut self, ctx: &'a Self::Context<'a>, ) -> Result<Option<T>, Self::Err>

Return the current row value from the editor. None results will remove the table row.

Provided Methods

fn focused_col(&self) -> Option<usize>

Returns the currently focused column. Used to scroll the column to fully visible.

fn start<'a>( &mut self, col: Option<usize>, ctx: &'a Self::Context<'a>, ) -> Result<(), Self::Err>

Start editing the current value. If a specific column should be focused initially it is given as the column index.

fn stop<'a>(&mut self, ctx: &'a Self::Context<'a>) -> Result<(), Self::Err>

Stop editing the current value. If necessary the editor can do some cleanup here.

Dyn Compatibility

This trait is not dyn compatible.

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