Field Detail

DEFAULT

static final ICarousel DEFAULT

Constant for default attributes of this immutable component.

Method Detail

getWidgetClass

default java.lang.String getWidgetClass()

Returns the client widget class.

Default: "zul.wgt.Carousel"

Specified by:

getWidgetClass in interface IComponent<ICarousel>

getActiveIndex

default int getActiveIndex()

Returns the index of the currently active slide.

Unlike Carousel.getActiveIndex(), the stored value is returned as given; the clamp to slideCount - 1 happens at render time only.

Default: 0.

withActiveIndex

ICarousel withActiveIndex(int activeIndex)

Returns a copy of this immutable component with the specified activeIndex.

Sets the index of the currently active slide.

Note: UiAgent.smartUpdate(Locator, SmartUpdater) is not supported for this property — ICarousel.Updater ships the raw attribute while the initial render ships the value clamped to slideCount - 1. Push a whole component with UiAgent.replaceWith(Locator, IComponent) instead.

Parameters:

activeIndex - the zero-based index of the slide to activate. An index past the last slide is clamped to slideCount - 1 when rendered.

Default: 0.

Returns:

A modified copy of the this object

Throws:

org.zkoss.zk.ui.WrongValueException - if activeIndex is negative.

isAutoplay

default boolean isAutoplay()

Returns whether the carousel advances through its slides automatically.

Default: false.

withAutoplay

ICarousel withAutoplay(boolean autoplay)

Returns a copy of this immutable component with the specified autoplay.

Sets whether the carousel advances through its slides automatically.

Parameters:

autoplay - true to start advancing slides automatically (using the interval), false to leave navigation manual.

Default: false.

Returns:

A modified copy of the this object

getInterval

default int getInterval()

Returns the autoplay interval in milliseconds.

Default: 5000.

withInterval

ICarousel withInterval(int interval)

Returns a copy of this immutable component with the specified interval.

Sets the autoplay interval in milliseconds.

Parameters:

interval - the autoplay interval in milliseconds; must be at least 500.

Default: 5000.

Returns:

A modified copy of the this object

Throws:

org.zkoss.zk.ui.WrongValueException - if interval is less than 500ms.

isShowArrows

default boolean isShowArrows()

Returns whether the previous/next navigation arrows are shown.

Default: true.

withShowArrows

ICarousel withShowArrows(boolean showArrows)

Returns a copy of this immutable component with the specified showArrows.

Sets whether the previous/next navigation arrows are shown.

Parameters:

showArrows - true to display the navigation arrows, false to hide them.

Default: true.

Returns:

A modified copy of the this object

isShowIndicators

default boolean isShowIndicators()

Returns whether the slide indicators (the position dots) are shown.

Default: true.

withShowIndicators

ICarousel withShowIndicators(boolean showIndicators)

Returns a copy of this immutable component with the specified showIndicators.

Sets whether the slide indicators (the position dots) are shown.

Parameters:

showIndicators - true to display the indicators, false to hide them.

Default: true.

Returns:

A modified copy of the this object

isLoop

default boolean isLoop()

Returns whether the carousel wraps around from the last slide back to the first (and vice versa).

Default: true.

withLoop

ICarousel withLoop(boolean loop)

Returns a copy of this immutable component with the specified loop.

Sets whether the carousel wraps around from the last slide back to the first (and vice versa).

Parameters:

loop - true to wrap around continuously, false to stop at the ends.

Default: true.

Returns:

A modified copy of the this object

isPause

default boolean isPause()

Returns whether autoplay pauses while the cursor hovers over the carousel.

Default: true.

withPause

ICarousel withPause(boolean pause)

Returns a copy of this immutable component with the specified pause.

Sets whether autoplay pauses while the cursor hovers over the carousel.

Parameters:

pause - true to pause autoplay on hover, false to keep advancing.

Default: true.

Returns:

A modified copy of the this object

isKeyboard

default boolean isKeyboard()

Returns whether the carousel reacts to left/right arrow keys when focused.

Default: true.

withKeyboard

ICarousel withKeyboard(boolean keyboard)

Returns a copy of this immutable component with the specified keyboard.

Sets whether the carousel reacts to left/right arrow keys when focused.

Parameters:

keyboard - true to enable arrow-key navigation, false to disable it.

Default: true.

Returns:

A modified copy of the this object

getOrient

@Nullable
default java.lang.String getOrient()

Returns the orientation along which the slides advance, or null when it was reset to the default.

Default: "horizontal".

withOrient
