- Method Detail
  - createCaption
```
org.zkoss.zk.ui.api.HtmlBasedComponent createCaption(T widget)
```
    Creates and returns the widget's caption component.
    Note: The renderer is not responsible for attaching the caption component to the passed widget instance. This is handled automatically during the widget initialization process.
    
    Parameters:
    
    widget - the widget component
    
    Returns:
    
    the created caption component
  - createContent
```
org.zkoss.zk.ui.api.HtmlBasedComponent createContent(T widget)
```
    Creates and returns the widget's (main) content component.
    Note: The renderer is not responsible for attaching the content component to the passed widget instance. This is handled automatically during the widget initialization process.
    However, some widgets (e.g. InputWidget) need to be able to access specific content components (e.g. input component) for updating purposes etc, which means that the renderer needs to pass those components to the widget directly. Please see InputWidget.setInputComponent(org.zkoss.zul.impl.api.InputElement) for an example.
    
    Parameters:
    
    widget - the widget component
    
    Returns:
    
    the created content component
