[−][src]Struct kas::WidgetId
Widget identifier
All widgets are assigned an identifier which is unique within the window. This type may be tested for equality and order.
This type is small and cheap to copy. Internally it is "NonZero", thus
Option<WidgetId>
is a free extension (requires no extra memory).
Identifiers are assigned when configured and when re-configured
(via kas::TkAction::Reconfigure
). Since user-code is not notified of a
re-configure, user-code should not store a WidgetId
.
