afterCompose

public void afterCompose()

Description copied from interface: AfterCompose

Invokes after ZK loader creates this component, initializes it and composes all its children, if any.

Specified by:

afterCompose in interface AfterCompose

setDynamicProperty

public void setDynamicProperty(java.lang.String name,
                      java.lang.Object value)
                        throws WrongValueException

Description copied from class: AbstractTag

Sets the dynamic property. Note: it converts the value to a string object (by use of Objects.toString(java.lang.Object)).

Note: it handles the style property specially. Refer to AbstractTag.setStyle(java.lang.String) for details.

Specified by:

setDynamicProperty in interface DynamicPropertied

Overrides:

setDynamicProperty in class AbstractTag

Throws:

WrongValueException

getDynamicProperty

public java.lang.Object getDynamicProperty(java.lang.String name)

Description copied from class: AbstractTag

Returns the dynamic property, or null if not found. Note: it must be a String object or null.

Specified by:

getDynamicProperty in interface DynamicPropertied

Overrides:

getDynamicProperty in class AbstractTag

getWidgetClass

public java.lang.String getWidgetClass()

Returns the widget class, "zhtml.Input".

Specified by:

getWidgetClass in interface Component

Overrides:

getWidgetClass in class Input

Since:

8.0.0

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
