GridState

Struct GridState 

Source
pub struct GridState {
    pub sel: BTreeSet<u64>,
    pub cur: Option<u64>,
    pub sort: Option<(usize, bool)>,
    pub widths: Vec<i32>,
    pub striped: bool,
    /* private fields */
}
Expand description

the app-owned state of a grid: selection (by key), current row, sort, column widths

Fields§

§sel: BTreeSet<u64>

the selected rows’ keys

§cur: Option<u64>

the current row (keyboard focus / last clicked)

§sort: Option<(usize, bool)>

the sort column and direction (true = descending); None = the app’s order

§widths: Vec<i32>

column widths set by the user (DIP, 0 = the column’s own)

§striped: bool

alternate row shading

Implementations§

Source§

impl GridState

Source

pub fn selected_in_order(&self) -> Vec<u64>

the keys selected, in display order of the last pass

Source

pub fn select_only(&mut self, key: Option<u64>)

select exactly this key (None: nothing) and make it current

Source

pub fn retain(&mut self, keys: &[u64])

drop selected keys that are no longer shown (after a refresh)
