Struct COLLAPSE_SCOPE

Source

pub struct COLLAPSE_SCOPE;

Expand description

Contextual service managed by collapse_scope.

Custom line widgets not derived from RuleLine! can participate in collapse_scope by setting COLLAPSABLE_LINE_ID during info build and using this service during measure and layout.
