Detailed Description

Specialization of ActivityBase for discrete time activities.

A discrete time activity is one where time proceeds in discrete steps, i.e. at given time instants.

◆ perform() [1/2]

bool slideshow::internal::DiscreteActivityBase::perform ( )

From Activity interface.

Derived classes should override, call this first and then perform their work.

Reimplemented from slideshow::internal::ActivityBase.

Referenced by perform().

◆ perform() [2/2]

virtual void slideshow::internal::DiscreteActivityBase::perform	(	sal_uInt32	nFrame,
		sal_uInt32	nRepeatCount
	)		const

pure virtual

Hook for derived classes.

This method is called for each discrete time instant, with nFrame denoting the frame number (starting with 0)

Parameters

nFrame	Current frame number.
nRepeatCount	Number of full repeats already performed

◆ startAnimation()

void slideshow::internal::DiscreteActivityBase::startAnimation ( )

overrideprotectedvirtual

Hook for derived classes.

This method will be called from the first perform() invocation, to signal the start of the activity.

Implements slideshow::internal::ActivityBase.
