Struct SelectionModel 

pub struct SelectionModel { /* private fields */ }

Tracks the set of selected row indices and an anchor for range selection.

Implementations

impl SelectionModel

pub fn new(mode: SelectionMode) -> Self

Create an empty selection model with the given mode.

pub fn mode(&self) -> SelectionMode

The selection mode.

pub fn len(&self) -> usize

Number of selected rows.

pub fn is_empty(&self) -> bool

Returns true if nothing is selected.

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

Returns true if row index is selected.

pub fn selected_sorted(&self) -> Vec<usize>

Selected indices in ascending order.

pub fn clear(&mut self)

Clear the entire selection.

pub fn click(&mut self, index: usize)

Handle a plain click on index: selects only that row (and sets the range anchor). No-op in SelectionMode::None.

pub fn ctrl_click(&mut self, index: usize)

Handle a ctrl/cmd-click on index: toggles that row’s membership without affecting others. In SelectionMode::Single it behaves like a plain click; in SelectionMode::None it is a no-op.

pub fn shift_click(&mut self, index: usize)

Handle a shift-click on index: selects the contiguous range from the current anchor to index (inclusive). Falls back to a plain click if there is no anchor or the mode is not multi.

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

Select every row in 0..row_count (multi mode only).
