public abstract class ImageSubmit
extends Submit

Used to create an image button inside a Form. Although it is occasionally useful to know the Pointon the image that was clicked (i.e., use the image as a kind of image map, which was the original intent of the HTML element), it is more commonly used to provide a graphic image for the user to click, rather than the rather plain <input type=submit>.

Method Detail

renderComponent

protected void renderComponent(IMarkupWriter writer,
                               IRequestCycle cycle)
Description copied from class: AbstractComponent
Invoked by AbstractComponent.render(IMarkupWriter, IRequestCycle)to actually render the component (with any parameter values already set). This is the method that subclasses must implement.


getDisabledImage

public abstract IAsset getDisabledImage()
parameter


getImage

public abstract IAsset getImage()
parameter


getNameOverride

public abstract java.lang.String getNameOverride()
parameter


setPoint

public abstract void setPoint(java.awt.Point point)
parameter


prepareForRender

protected void prepareForRender(IRequestCycle cycle)
Description copied from class: AbstractComponent
Invoked by AbstractComponent.render(IMarkupWriter, IRequestCycle)to prepare the component to render. This implementation sets JavaBeans properties from matching bound parameters. This implementation does nothing.

Overrides:
prepareForRender in class AbstractComponent
