pub struct TableViewHandle { /* private fields */ }Expand description
A handle on a mounted TableView, to scroll it to a row from outside
the widget — a view-model reacting to a search hit, a “go to row” command.
Cheap to clone, valid before the table is mounted, and it survives the table’s rebuilds. Its methods never compute an offset when they are called: they record the request and ask for a layout pass, and the table applies it there, after row measurement and scroll anchoring have settled. So a model change made in the same turn (rows inserted above, say) is accounted for, a request made before mount is applied at the first layout, and a later request replaces an earlier pending one. A request on a table with no rows is dropped; a row past the end reveals the last row.
let table = TableView::new(model);
let handle = table.handle();
// … add the columns, `ctx.add(table)`, then later, from any handler:
handle.ensure_row_visible(1_250);Implementations§
Source§impl TableViewHandle
impl TableViewHandle
Sourcepub fn scroll_to_row(&self, row: usize)
pub fn scroll_to_row(&self, row: usize)
Scroll so that row is aligned to the top of the viewport, as far as
the scroll range allows, at the next layout pass.
Sourcepub fn ensure_row_visible(&self, row: usize)
pub fn ensure_row_visible(&self, row: usize)
Scroll the minimum distance that makes row fully visible, at the
next layout pass; no scroll when it already is.
