request: Option<ContextMenuRequest>

Implementations

impl ContextMenu

pub fn standard(col: usize, anchor: Point<Pixels>) -> Self

Standard column-header menu. Constructed by state when the user right-clicks a column header or sort button.

pub fn custom( col: usize, anchor: Point<Pixels>, items: Vec<MenuItem>, request: ContextMenuRequest, ) -> Self

Construct a custom menu from provider-supplied items plus the captured request snapshot. col is used for built-in action dispatch when the provider composes BuiltIn items.

pub fn width_for(&self, char_width: f32) -> f32

Width needed to fit the longest label, with padding, bounded below by MENU_MIN_WIDTH.

pub fn total_height(&self) -> f32

Total height including inner padding.

pub fn resolved_position( &self, grid_ox: f32, grid_oy: f32, vw: f32, vh: f32, char_width: f32, ) -> Point<Pixels>

Resolve the menu’s final top-left corner in grid-relative space, given the grid origin in window space (grid_ox, grid_oy) and the window viewport size (vw, vh).

The menu must never be clipped by the grid area — only the window edge constrains it. Vertically it always opens downward from the anchor unless the full menu would not fit below the anchor within the window, in which case it flips to open upward (anchored so its bottom sits at the anchor). Horizontally it shifts left to stay on-screen.

Returned in grid-relative coordinates so it composes directly with hover_at and the widget’s grid-relative pointer math. Paint adds the grid origin back to reach absolute window space.
