Struct ClickMap 

pub struct ClickMap { /* private fields */ }

The mouse model shared by every preferences section: rows select, controls act, the wheel moves the selection. A click is always turned into the key it stands for, so the screen runs it through the same path a key takes — settings write-back included.

Rows are list rows and get no hover; controls are click targets and register for it (components::clickable).

Implementations

impl ClickMap

pub fn list_rows(&mut self, inner: Rect, offset: usize, len: usize)

Record the visible rows of a scrolled list drawn in inner: item offset on the first line, up to len items or the bottom edge. Call after rendering, once the list has settled its offset.

pub fn clear(&mut self)

Forget the last render’s targets — call at the top of render.

pub fn row(&mut self, rect: Rect, row: usize)

Record a selectable row.

pub fn control(&mut self, rect: Rect, row: usize, key: KeyCode)

Record a control that runs key for row; it gets hover.

pub fn resolve( &self, m: &MouseEvent, selected: Option<usize>, activate: Option<KeyCode>, ) -> SectionMouse

Resolve a mouse event. selected is the section’s current row and activate the key a click on the already-selected row runs (None when re-clicking does nothing, e.g. a theme list).
