Grid geometry: where a cell is, and which cell is under a point. -//! -//! Extracted from `grid.rs`, which is excluded from coverage because it -//! carries the `script_mod!` DSL and cannot be constructed without a -//! `ScriptVm`. That exclusion was hiding real logic: of 59 functions in -//! `grid.rs`, 36 take no `cx`, no `Event` and no `Scope` — they are -//! arithmetic over plain numbers, and none of them had a single test. -//! -//! This module holds that arithmetic. `GridMetrics` is a plain struct with -//! no Makepad dependency, so every function here is directly testable, and -//! `SpreadsheetGrid` keeps one as a field rather than keeping the maths. -//! -//! ## Why the layout is cached -//! -//! SPREADSHEET REVIEW items 7 and 10 name the defect: `col_at_x` and -//! `row_at_y` scanned linearly from the scroll offset on every hit test, -//! and `cell_abs_rect` summed column widths from `first_col` on every call -//! — O(N) per cell lookup, executed per frame and per pointer event. -//! -//! `GridMetrics` keeps prefix sums instead. Offsets are recomputed only -//! when a width or height actually changes, hit testing is a binary search, -//! and a cell's position is one subtraction. The behaviour is identical to -//! the linear version, which is what the tests pin: several of them assert -//! the two agree, so the optimisation cannot quietly change an answer. -//! -//! ## Coordinate conventions, stated once -//! -//! - Absolute coordinates include the widget's own origin (`origin`). -//! - Frozen rows and columns sit immediately after the headers and do not -//! scroll. Everything else is offset by the fractional scroll position. -//! - A scroll offset is in *cells*, not pixels: `2.5` means "two whole -//! columns scrolled off, and half of the third". The fractional part is -//! multiplied by the *default* width, matching the scrollbar's model. - -/// Sizes and scroll state, enough to place any cell. -#[derive(Clone, Debug, PartialEq)] -pub struct GridMetrics { - /// Widget origin in absolute coordinates. - pub origin: (f64, f64), - /// Row-header strip width, and column-header strip height. - pub row_header_width: f64, - pub col_header_height: f64, - /// Default cell size, used where no override exists. - pub default_col_width: f64, - pub default_row_height: f64, - /// Per-index overrides, sparse. - pub col_widths: Vec<(u32, f64)>, - pub row_heights: Vec<(u32, f64)>, - /// Frozen pane sizes, in cells. - pub frozen_cols: u32, - pub frozen_rows: u32, - /// Scroll position, in cells; the fraction is a partial first cell. - pub scroll_col: f64, - pub scroll_row: f64, - /// Total grid extent, in cells. - pub num_cols: u32, - pub num_rows: u32, -} - -impl Default for GridMetrics { - fn default() -> Self { - Self { - origin: (0.0, 0.0), - row_header_width: 50.0, - col_header_height: 28.0, - default_col_width: 100.0, - default_row_height: 26.0, - col_widths: Vec::new(), - row_heights: Vec::new(), - frozen_cols: 0, - frozen_rows: 0, - scroll_col: 0.0, - scroll_row: 0.0, - num_cols: 64, - num_rows: 512, - } - } -} - -impl GridMetrics { - /// Width of one column, honouring an override. - pub fn col_width(&self, col: u32) -> f64 { - self.col_widths - .iter() - .find(|(c, _)| *c == col) - .map(|(_, w)| *w) - .unwrap_or(self.default_col_width) - } - - /// Height of one row, honouring an override. - pub fn row_height(&self, row: u32) -> f64 { - self.row_heights - .iter() - .find(|(r, _)| *r == row) - .map(|(_, h)| *h) - .unwrap_or(self.default_row_height) - } - - /// Total width of columns in `[from, to)`. - /// - /// Empty when `to <= from`, rather than panicking or wrapping.
