Constructor Detail

ContentTag

public ContentTag(java.lang.String tagnm)

ContentTag

public ContentTag(java.lang.String tagnm,
                  java.lang.String content)

Method Detail

getWidgetClass

public java.lang.String getWidgetClass()

Returns the widget class, "zhtml.Content".

Specified by:

getWidgetClass in interface Component

Overrides:

getWidgetClass in class AbstractTag

See Also:

Component.setWidgetClass(java.lang.String)

getContent

public java.lang.String getContent()

Returns the content.

setContent

public void setContent(java.lang.String content)

Sets the content.

isChildable

protected boolean isChildable()

No child is allowed.

Overrides:

isChildable in class AbstractTag

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException

Description copied from class: AbstractComponent

Called by (ComponentCtrl.redraw(java.io.Writer)) to render the properties, excluding the enclosing tag and children.

Default: it renders AbstractComponent.getId() if it was assigned, and event names if listened (and listed in AbstractComponent.getClientEvents()).

Note: it doesn't render AbstractComponent.getWidgetClass(), AbstractComponent.getUuid() and AbstractComponent.getMold(), which are caller's job.

Overrides:

renderProperties in class AbstractTag

Throws:

java.io.IOException

redrawChildrenDirectly

protected void redrawChildrenDirectly(TagRenderContext rc,
                                      Execution exec,
                                      java.io.Writer out)
                               throws java.io.IOException

Description copied from class: AbstractTag

Renders the children directly to the given output. Notice it is called only if AbstractTag.redraw(java.io.Writer) is going to render the content (HTML tags) directly. If it is about to generate the JavaScript code AbstractComponent.redrawChildren(java.io.Writer) will be called instead.

You have to override this method if the deriving class has additional information to render.

Overrides:

redrawChildrenDirectly in class AbstractTag

Throws:

java.io.IOException
