A

public A(java.lang.String label,
         java.lang.String image)
Method Detail

isDisabled

public boolean isDisabled()
Returns whether it is disabled.

Default: false.

Specified by:
isDisabled in interface Disable

setDisabled

public void setDisabled(boolean disabled)
Sets whether it is disabled.

Specified by:
setDisabled in interface Disable

getDir

public java.lang.String getDir()
Returns the direction.

Default: "normal".


setDir

public void setDir(java.lang.String dir)
            throws WrongValueException
Sets the direction to layout with image.

Parameters:
dir - either "normal" or "reverse".
Throws:
WrongValueException

getHref

public java.lang.String getHref()
Returns the href that the browser shall jump to, if an user clicks this button.

Default: null. If null, the button has no function unless you specify the onClick event listener.

If it is not null, the onClick event won't be sent.


setHref

public void setHref(java.lang.String href)
Sets the href.


getTarget

public java.lang.String getTarget()
Returns the target frame or window.

Note: it is useful only if href (setHref(java.lang.String)) is specified (i.e., use the onClick listener).

Default: null.


setTarget

public void setTarget(java.lang.String target)
Sets the target frame or window.

Parameters:
target - the name of the frame or window to hyperlink.

getTabindex

public int getTabindex()
Returns the tab order of this component.

Default: 0 (means the same as browser's default).


setTabindex

public void setTabindex(int tabindex)
                 throws WrongValueException
Sets the tab order of this component.

Throws:
WrongValueException

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException
Description copied from class: HtmlBasedComponent
Renders the content of this component, excluding the enclosing tags and children.

See also ZK Client-side Reference: Property Rendering

Overrides:
renderProperties in class LabelImageElement
Throws:
java.io.IOException

renderCrawlable

protected void renderCrawlable(java.lang.String label)
                        throws java.io.IOException
Description copied from class: LabelElement
Renders the crawlable information. It is called by LabelElement.renderProperties(org.zkoss.zk.ui.sys.ContentRenderer), and designed to be overridden if the deriving class wants to generate it differently.

Default: org.zkoss.zul.impl.Utils.renderCrawlableText(label)

Overrides:
renderCrawlable in class LabelElement
Throws:
java.io.IOException

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.

Overrides:
getZclass in class HtmlBasedComponent
See Also:
HtmlBasedComponent.getSclass()
