stmUiEventEngine::MUiEvent Class Reference

class stmUiEventEngine::MUiEvent : public stmUiEventEngine::MUiEventSpeed

The UI event interface, UI events are touch, hold, move and release. Note that currently the interface is not OS agnostic enough. It is using TPoint , TTimeIntervalMicroSeconds etc. types which should be replaced with some standard types/classes.

speedX()

float

speedX

(

)

const [pure virtual]

Speed. Speed is calculated based on the previous event.
