public void setShadow(boolean shadow)
```
    True to enable a shadow that will be displayed behind the widget (defaults to false, pre-render).
    
    Parameters:
    shadow - true to enable the shadow
  - setShadowPosition
```
public void setShadowPosition(Layer.ShadowPosition shadowPosition)
```
    Sets the shadow position (defaults to SIDES, pre-render).
    
    Parameters:
    shadowPosition - the position
  - setSize
```
public void setSize(String width,
           String height)
```
    Sets the width and height of the widget. This method fires the Resize event.
    
    Overrides:
    
    setSize in class UIObject
    
    Parameters:
    width - the new width to set
    height - the new height to set
  - setStateful
```
public void setStateful(boolean stateful)
```
    A flag which specifies if the component is stateful (defaults to false). The widget must have either a setStateId(String) or setId(String) assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a widget.
    
    Parameters:
    stateful - true to enable state
  - setStateId
```
public void setStateId(String stateId)
```
    Sets the widget's state id which is a unique id for this widget to use for state management purposes (defaults to the widget id if one was set, otherwise null if the widget is using a generated id).
    
    Parameters:
    stateId - the state id
  - setTabIndex
```
public void setTabIndex(int tabIndex)
```
    Sets the component's tab index. Subclasses may override this to set the tab index on a specific element for better focus behavior - they are also responsible for setting the tabIndex field.
    
    Parameters:
    tabIndex - the tab index
  - setToolTip
```
public void setToolTip(SafeHtml html)
```
    Sets the widget's tool tip.
    
    Parameters:
    html - the tip text or html
  - setToolTip
```
public void setToolTip(String text)
```
    Sets the widget's tool tip.
    
    Parameters:
    text - the tip text
  - setToolTipConfig
```
public void setToolTipConfig(ToolTipConfig config)
```
    Sets the widget's tool tip with the given config.
    
    Parameters:
    config - the tool tip config
  - setVisible
```
public void setVisible(boolean visible)
```
    Convenience function to hide or show this widget by boolean.
    
    Specified by:
    
    setVisible in interface HasVisibility
    
    Overrides:
    
    setVisible in class UIObject
    
    Parameters:
    visible - the visible state
  - setWidth
```
public void setWidth(int width)
```
    Sets the width of the widget. This method fires the Resize event.
    
    Parameters:
    width - the new width to set
  - setWidth
```
public void setWidth(String width)
```
    Sets the width of the widget. This method fires the Resize event.
    
    Overrides:
