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.

CurrentXY()

const TPoint &

CurrentXY

(

)

const [pure virtual]

Current position in _screen_ coordinates

Index()

int

Index

(

)

const [pure virtual]

The index of the UI event. In single touch this is always 0

const TPoint &

PreviousXY

(

)

const [pure virtual]

Previous position in _screen_ coordinates

StartPos()

const TPoint &

StartPos

(

)

const [pure virtual]

The starting position of the gesture in _screen_ coordinates

StateTransition()

TTimeIntervalMicroSeconds

StateTransition

(

)

const [pure virtual]

Target()

void *

Target

(

)

const [pure virtual]

Target identifier (in practice the CCoeControl* of the window)

TimerExpired()

bool

TimerExpired

(

)

const [pure virtual]

true, if the UI event was generated because of timer expiration

speedX()

float

speedX

(

)

const [pure virtual]

Speed. Speed is calculated based on the previous event.

speedY()

float

speedY

(

)

const [pure virtual]
