Struct rat_widget::table::selection::RowSelection

pub struct RowSelection {
    pub lead_row: Option<usize>,
    pub scroll_selected: bool,
}

Allows selecting a single row of the table.

This is the right one if you want a list-style selection for your table.

This one only supports row-selection.

Fields

lead_row: Option<usize>

Selected row.

scroll_selected: bool

Scrolls the selection instead of the offset.

Implementations

impl RowSelection

pub fn new() -> RowSelection

New selection.

pub fn clear(&mut self)

Clear the selection.

pub fn scroll_selected(&self) -> bool

Scroll selection instead of offset.

pub fn set_scroll_selected(&mut self, scroll: bool)

Scroll selection instead of offset.

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

The current selected row.

pub fn has_selection(&self) -> bool

Has some selection.

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

Select a row. This function doesn’t care if the given row actually exists in the table.

pub fn items_added(&mut self, pos: usize, n: usize)

Update the state to match adding items.

pub fn items_removed(&mut self, pos: usize, n: usize)

Update the state to match removing items.

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

Select the given row, limit between 0 and maximum.

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

Select the next row, cap at maximum.

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

Select the previous row.

Trait Implementations

impl Clone for RowSelection

fn clone(&self) -> RowSelection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowSelection

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

Formats the value using the given formatter.

impl Default for RowSelection

fn default() -> RowSelection

Returns the “default value” for a type.

impl TableSelection for RowSelection

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, _column: usize, _row: usize) -> bool

Specific cell is selected.

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

Selection lead, or the sole selected index.
