Constructor Detail

Slider

public Slider()

Slider

public Slider(int curpos)

Parameters:

curpos - the current position (default: 0)

Method Detail

getZclass

public java.lang.String getZclass()

Description copied from class: HtmlBasedComponent

Returns the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (@{link #getMold}).

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Specified by:

getZclass in interface HtmlBasedComponent

Overrides:

getZclass in class HtmlBasedComponent

HtmlBasedComponent.getSclass(), HtmlBasedComponent.getRealSclass()

getOrient

public java.lang.String getOrient()

Returns the orient.

Default: "horizontal".

Specified by:

getOrient in interface Slider

setOrient

public void setOrient(java.lang.String orient)
               throws WrongValueException

Sets the orient.

Default : "horizontal"

Specified by:

setOrient in interface Slider

Parameters:

orient - either "horizontal" or "vertical".

Throws:

WrongValueException

Since:

3.5.0

getSlidingtext

public java.lang.String getSlidingtext()

Returns the sliding text.

Default : "{0}"

Specified by:

getSlidingtext in interface Slider

Since:

3.0.1

setSlidingtext

public void setSlidingtext(java.lang.String slidingtext)

Sets the sliding text. The syntax "{0}" will be replaced with the position at client side.

Specified by:

setSlidingtext in interface Slider

Since:

3.0.1

getCurpos

public final int getCurpos()

Returns the current position of the slider.

Default: 0.

setCurpos

public final void setCurpos(int curpos)
                     throws WrongValueException

Sets the current position of the slider. If negative, 0 is assumed. If larger than getMaxpos(), getMaxpos() is assumed.

Throws:

WrongValueException

getMaxpos

public final int getMaxpos()

Returns the maximum position of the slider.

Default: 100.

setMaxpos

public final void setMaxpos(int maxpos)
                     throws WrongValueException

Sets the maximum position of the slider.

Throws:

WrongValueException - if non-positive maxpos is passed

isVertical

public boolean isVertical()

Returns whether it is a vertical slider.

Specified by:

isVertical in interface Slider

Since:

3.5.0

getPageIncrement

public final int getPageIncrement()

Returns the amount that the value of getCurpos() changes by when the tray of the scroll bar is clicked.

Default: 10.

setPageIncrement

public final void setPageIncrement(int pginc)
                            throws WrongValueException

Sets the amount that the value of getCurpos() changes by when the tray of the scroll bar is clicked.

Throws:

WrongValueException

getName

public java.lang.String getName()

Returns the name of this component.

Default: null.

The name is used only to work with "legacy" Web application that handles user's request by servlets. It works only with HTTP/HTML-based browsers. It doesn't work with other kind of clients.

Don't use this method if your application is purely based on ZK's event-driven model.

Specified by:

getName in interface Slider

Since:

3.0.0

setName

public void setName(java.lang.String name)

Sets the name of this component.

The name is used only to work with "legacy" Web application that handles user's request by servlets. It works only with HTTP/HTML-based browsers. It doesn't work with other kind of clients.

Don't use this method if your application is purely based on ZK's event-driven model.

Specified by:

setName in interface Slider

Parameters:

name - the name of this component.

Since:

3.0.0

setMold

public void setMold(java.lang.String mold)

Sets the mold.

Specified by:

setMold in interface Component

Overrides:

setMold in class AbstractComponent

Parameters:

mold - default , scale

ComponentDefinition

getOuterAttrs

public java.lang.String getOuterAttrs()

Description copied from class: HtmlBasedComponent

Returns the exterior attributes for generating the enclosing HTML tag; never return null.

Used only by component developers.

Default: Generates the tooltip text, style, sclass, draggable and droppable attribute if necessary. In other words, the corresponding attribute is generated if HtmlBasedComponent.getTooltiptext(), HtmlBasedComponent.getRealStyle(), HtmlBasedComponent.getSclass(), HtmlBasedComponent.getDraggable(), HtmlBasedComponent.getDroppable() are defined.

You have to call both HtmlBasedComponent.getOuterAttrs() and HtmlBasedComponent.getInnerAttrs() to generate complete attributes.

For simple components that all attributes are put on the outest HTML element, all you need is as follows.

<xx id="${self.uuid}"${self.outerAttrs}${self.innerAttrs}>

If you want to put attributes in a nested HTML element, you shall use the following pattern. Notice: if HtmlBasedComponent.getInnerAttrs() in a different tag, the tag must be named with "${self.uuid}!real".

<xx id="${self.uuid}"${self.outerAttrs}>
 <yy id="${self.uuid}!real"${self.innerAttrs}>...

Note: This class handles non-deferrable event listeners automatically. However, you have to invoke AbstractComponent.appendAsapAttr(java.lang.StringBuffer, java.lang.String) for each event the component handles in HtmlBasedComponent.getOuterAttrs() as follows.

        appendAsapAttr(sb, Events.ON_OPEN);
  appendAsapAttr(sb, Events.ON_CHANGE);

Theorectically, you could put any attributes in either HtmlBasedComponent.getInnerAttrs() or HtmlBasedComponent.getOuterAttrs(). However, zkau.js assumes all attributes are put at the outer one. If you want something different, you have to provide your own setAttr (refer to how checkbox is implemented).

Overrides:

getOuterAttrs in class XulElement

isChildable

public boolean isChildable()

Not childable.

Specified by:

isChildable in interface Component

Overrides:

isChildable in class AbstractComponent

newExtraCtrl

protected java.lang.Object newExtraCtrl()

Description copied from class: HtmlBasedComponent

Used by AbstractComponent.getExtraCtrl() to create a client control. It is used only by component developers.

Defaut: creates an instance of HtmlBasedComponent.ExtraCtrl.

Overrides:

newExtraCtrl in class HtmlBasedComponent
