Module suzy::selectable [−][src]
An interface for Widgets to respond to interaction.
Widgets like Button require their content implement the trait Selectable
so that they can update their graphics in response to a change in the
button’s state.
The type SelectableData provides a simple way to select between values.
The type SelectableIgnored provides a no-op implementation of
Selectable, in case a particular Widget has no need to respond to a
change in selection state.
Selectable implementations are provided with an opaque struct
SelectionState. This can be converted into a number of “versioned”
enums. This pattern allows additional states to be added in the future
with reasonable fallbacks for backwards-compatibility.
