Holder for InteractionState dedicated to UI gestures and complex interactions.

WIP-WIP as of 3/2021

as of 3/2021 the whole scheme for addressing gestures and actual state implementations is rather just guesswork ///////////////////////////////////TODO do we need a translation unit interaction-state.cpp (otherwise delete it!)

Member Function Documentation

◆ getStateFor()

InteractionState & getStateFor	(	Action	action,
		Scope	qualifier
	)

Decode the classification of the kind of interaction and gesture, and thus translate to a concrete InteractionState implementation.

Returns: reference to the actual UI state with respect to the specific gesture requested, which can then e.g. be used to wire a specific UI widget to become responsive to this kind of gesture.

Todo:: as of 4/2021, interactions and UI state handling can be considered an early draft; since the UI needs to be fleshed out in more detail in order to decide on a proper organisation and possibly flexible configuration. In the meantime, we use some hard wired mappings to actual InteractionState implementations
