Struct Column 

pub struct Column<T: 'static> { /* private fields */ }

Single column declaration. Column ids must be stable, unique strings — they’re the persistence key for sort, filter, width, and ordering.

Implementations

impl<T: 'static> Column<T>

pub fn new( id: impl Into<String>, header: impl Into<LocalizedString>, cell: impl Fn(&T, &CellContext) -> Box<dyn Widget> + 'static, ) -> Self

Create a column with a stable id, a localized header label, and a cell builder that takes &T plus a CellContext and returns a boxed widget.

pub fn width(self, w: ColumnWidth) -> Self

pub fn min_width(self, px: f32) -> Self

pub fn max_width(self, px: f32) -> Self

pub fn alignment(self, a: Alignment) -> Self

pub fn resizable(self, b: bool) -> Self

pub fn reorderable(self, b: bool) -> Self

pub fn sortable(self, b: bool) -> Self

pub fn filterable(self, b: bool) -> Self

pub fn editable(self, b: bool) -> Self

Mark the column as editable. Default false. F2 / type-to-edit only enter edit mode on cells of editable columns; the on_cell_edit_request hook also fires only for these. Cells of non-editable columns continue to render their static delegate regardless of editing_cell.

pub fn edit_triggers(self, triggers: EditTriggers) -> Self

Override the view’s EditTriggers for this column alone.

The reason the set is not only table-wide: a table’s columns rarely want the same gesture. A tree column has to keep click-to-select and double-click-to-open, while the plain value columns beside it are exactly where one click to edit belongs. Unset columns inherit the view’s set.

pub fn effective_edit_triggers(&self, view: EditTriggers) -> EditTriggers

The triggers in force for this column, given the view’s set — the question the body pane and the key handler both ask, and the one an application’s own tests want to ask about their column set.

A non-editable column never opens an editor, whatever either says.

pub fn pinned(self, side: PinnedSide) -> Self

pub fn truncation(self, p: TruncationPolicy) -> Self

pub fn header_override( self, f: impl Fn(&ColumnContext) -> Box<dyn Widget> + 'static, ) -> Self

Override the default header rendering (label + sort/filter indicators). The closure receives a ColumnContext reflecting the current sort/filter state.

pub fn id(&self) -> &str

Stable column id (the persistence key for sort, filter, width, and ordering signals).

Trait Implementations
