Struct CellSelectionModel 

pub struct CellSelectionModel { /* private fields */ }

Cell-level selection state for TableSelectionMode::SingleCell / MultiCell. Tracks (row, col) pairs in visible-index space.

Mirrors teksilo_data::SelectionModel’s API surface (signal-backed, auto-adjustable on data mutations) but keyed by (row, col) instead of row alone.

Implementations

impl CellSelectionModel

pub fn new(mode: TableSelectionMode) -> Self

Construct a model. Panics if mode is not a cell mode — callers in row mode should use teksilo_data::SelectionModel.

pub fn mode(&self) -> TableSelectionMode

pub fn selection_signal(&self) -> Signal<BTreeSet<(usize, usize)>>

pub fn is_selected(&self, row: usize, col: usize) -> bool

pub fn count(&self) -> usize

pub fn select(&self, row: usize, col: usize)

Replace the selection with the single cell (row, col) and set the anchor.

pub fn toggle(&self, row: usize, col: usize)

Toggle the cell (row, col) (Ctrl-click). In SingleCell mode this behaves like select.

pub fn extend_to(&self, row: usize, col: usize)

Extend the selection to include the rectangular range from the anchor to (row, col). In SingleCell mode this falls back to select.

pub fn select_all(&self, row_count: usize, col_count: usize)

Select every cell in 0..row_count × 0..col_count.

pub fn clear(&self)

pub fn adjust_for_row_insert(&self, at_row: usize, count: usize)

Adjust selection after count rows are inserted starting at at_row. Existing selections at indices >= at_row shift up.

pub fn adjust_for_row_remove(&self, at_row: usize, count: usize)

Adjust selection after count rows starting at at_row are removed. Selections within the removed range are dropped; later rows shift down.

pub fn adjust_for_row_move(&self, from: usize, to: usize, count: usize)

Adjust selection after a block of count rows moved from from to to (a post-removal index, matching ListModel::move_item). Selected cells follow their rows; columns are untouched.

pub fn adjust_for_column_insert(&self, at_col: usize, count: usize)

Adjust selection after count columns are inserted at at_col.

Reserved for future dynamic-column support. TableView/TreeTableView columns are declared once via .add_column()/.columns() and are static for the widget’s lifetime — there is no runtime insert/remove API today, so nothing calls this. A column reorder or pin-toggle permutes positions instead (see remap_columns), which is what the current views actually use. Kept (not removed) as public API in case a future dynamic-column feature needs the offset-shift semantics this and adjust_for_column_remove already implement and test.

pub fn adjust_for_column_remove(&self, at_col: usize, count: usize)

Adjust selection after count columns starting at at_col are removed.

Reserved for future dynamic-column support — see the doc comment on adjust_for_column_insert; nothing calls this today for the same reason.
