An item of a TypedColumnView.

Required Associated Constants

const COLUMN_NAME: &'static str

The columns created for this list item.

Provided Associated Constants

const ENABLE_RESIZE: bool = false

Whether to enable resizing for this column

const ENABLE_EXPAND: bool = false

Whether to enable automatic expanding for this column

Required Associated Types

type Root: IsA<Widget>

The top-level widget for the list item.

type Widgets

The widgets created for the list item.

type Item: Any

Item whose data is shown in this column.

Required Methods

fn setup(list_item: &ListItem) -> (Self::Root, Self::Widgets)

Construct the widgets.

Provided Methods

fn header_title() -> String

Returns the shown title for the column. By default shows RelmColumn::COLUMN_NAME. Useful for translations

fn bind( _item: &mut Self::Item, _widgets: &mut Self::Widgets, _root: &mut Self::Root, )

Bind the widgets to match the data of the list item.

fn unbind( _item: &mut Self::Item, _widgets: &mut Self::Widgets, _root: &mut Self::Root, )

Undo the steps of RelmColumn::bind() if necessary.

fn teardown(_list_item: &ListItem)

Undo the steps of RelmColumn::setup() if necessary.

fn sort_fn() -> OrdFn<Self::Item>

Sorter for column.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<C> RelmColumn for C

where C: LabelColumn,

const COLUMN_NAME: &'static str = C::COLUMN_NAME

const ENABLE_RESIZE: bool = C::ENABLE_RESIZE

const ENABLE_EXPAND: bool = C::ENABLE_EXPAND

type Root = Label

type Widgets = ()

type Item = <C as LabelColumn>::Item
