Detailed Description

A value class that defines a transition effect.

This class defines an animation used as a transition to show or hide a widget.

The animation can be defined as a motion effect (e.g. sliding in or out), optionally combined with a fade effect. A timing function defines how the effects(s) are animated during the total duration of the animation.

Constructor & Destructor Documentation

◆ WAnimation() [1/2]

Wt::WAnimation::WAnimation ( )

Default constructor.

Creates an animation that actually represent no animation. (effects() == 0).

◆ WAnimation() [2/2]

Wt::WAnimation::WAnimation ( WFlags< AnimationEffect effects,
TimingFunction  timing = TimingFunction::Linear,
int  duration = 250 
)

Creates an animation.

An animation is created with given effects, timing and duration.

Member Function Documentation

◆ duration()

int Wt::WAnimation::duration ( ) const

Returns the duration.

See also
setDuration()

◆ effects()

WFlags<AnimationEffect> Wt::WAnimation::effects ( ) const

Returns animation effects.

See also
setEffects()

◆ empty()

bool Wt::WAnimation::empty ( ) const

Returns whether the animation is empty.

An animation is empty (meaning the transition is instant), if the duration is 0, or if no effects are defined.

◆ operator!=()

bool Wt::WAnimation::operator!= ( const WAnimation other) const

Comparison operator.

Returns true if the transitions are different.

◆ operator==()

bool Wt::WAnimation::operator== ( const WAnimation other) const

Comparison operator.

Returns true if the transitions are exactly the same.

◆ setDuration()

void Wt::WAnimation::setDuration ( int  msecs)

Sets the duration.

The default animation duration is 250 ms.

See also
duration()

◆ setEffects()

void Wt::WAnimation::setEffects ( WFlags< AnimationEffect effects)

Sets the animation effects.

A motion effect (SlideInFromLeft, SlideInFromRight, SlideInFromBottom, SlideInFromTop or Pop) can be combined with a fade effect (Fade).

When effects are 0, the animation does not actually specify an animation, but instead an instant transition.

◆ setTimingFunction()

void Wt::WAnimation::setTimingFunction ( TimingFunction  function)

Sets a timing function.

The default timinig function is TimingFunction::Linear.

◆ timingFunction()

TimingFunction Wt::WAnimation::timingFunction ( ) const

Returns the timing function.
