Struct CellSelection 

pub struct CellSelection {
    pub lead_cell: Option<(usize, usize)>,
}

Select a single cell in the table.

This one supports cell + column + row selection.

Fields

lead_cell: Option<(usize, usize)>

Selected cell.

Implementations

impl CellSelection

pub fn new() -> CellSelection

New

pub fn clear(&mut self)

Clear the selection.

pub fn selected(&self) -> Option<(usize, usize)>

Selected cell.

pub fn has_selection(&mut self) -> bool

pub fn select_cell(&mut self, select: Option<(usize, usize)>) -> bool

Select a cell.

pub fn select_row(&mut self, select: Option<usize>) -> bool

Select a row. Column stays the same.

pub fn select_column(&mut self, select: Option<usize>) -> bool

Select a column, row stays the same.

pub fn move_to( &mut self, select: (usize, usize), maximum: (usize, usize), ) -> bool

Select a cell, clamp between 0 and maximum.

pub fn move_to_col(&mut self, col: usize, maximum: usize) -> bool

Select a column. Row stays the same.

pub fn move_to_row(&mut self, row: usize, maximum: usize) -> bool

Select a row. Column stays the same.

pub fn move_down(&mut self, n: usize, maximum: usize) -> bool

Select the next row, clamp between 0 and maximum.

pub fn move_up(&mut self, n: usize, maximum: usize) -> bool

Select the previous row, clamp between 0 and maximum.

pub fn move_right(&mut self, n: usize, maximum: usize) -> bool

Select the next column, clamp between 0 and maximum.

pub fn move_left(&mut self, n: usize, maximum: usize) -> bool

Select the previous row, clamp between 0 and maximum.

Trait Implementations

impl Clone for CellSelection

fn clone(&self) -> CellSelection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CellSelection

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for CellSelection

fn default() -> CellSelection

Returns the “default value” for a type.

impl TableSelection for CellSelection

fn count(&self) -> usize

Number of rowss selected.

fn is_selected_row(&self, row: usize) -> bool

Row is selected. This can be separate from is_selected_cell.

fn is_selected_column(&self, column: usize) -> bool

Column is selected. This can be separate from is_selected_cell.

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

Specific cell is selected.

fn lead_selection(&self) -> Option<(usize, usize)>

Selection lead, or the sole selected index.
