Struct FocusBranches 

pub struct FocusBranches;

Branches as captions: a tree row with shown children (a branch) takes the focus but not the selection, as a group caption does, and a command over one acts on the leaves of its subtree that pass the view, those under collapsed branches too, in the order of Projection::rows, with every column. Cmd/Ctrl+A, Shift ranges and drags leave branches out. Group captions and leaves behave as with FocusCaptions.

A leaf that gets children stays selected (by key); new gestures leave it out.

Trait Implementations

impl Clone for FocusBranches

fn clone(&self) -> FocusBranches

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FocusBranches

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FocusBranches

fn default() -> FocusBranches

Returns the “default value” for a type.

impl<R: GridRow> SelectionPolicy<R> for FocusBranches

fn is_selectable(&self, line: &SelectableLine<'_, R>) -> bool

Returns true if line can be selected. A selectable caption adds its group’s live rows to the selection; a selectable row itself.

fn line_scope( &self, context: &LineScopeContext<'_, R>, ) -> Option<ScopedSelection<R::Key>>

The scope of a command whose target is context.line(); None: the command acts on scoped_selection().
