  - init
```
protected void init()
```
    Description copied from class: AbstractConnector
    
    Called when the connector has been initialized. Override this method to perform initialization of the connector.
    
    Overrides:
    
    init in class AbstractConnector
  - updateFromUIDL
```
public void updateFromUIDL(UIDL uidl,
                           ApplicationConnection client)
```
    Specified by:
    
    updateFromUIDL in interface Paintable
  - onStateChanged
```
public void onStateChanged(StateChangeEvent stateChangeEvent)
```
    Description copied from interface: StateChangeEvent.StateChangeHandler
    
    Notifies the event handler that the state has changed.
    
    Specified by:
    
    onStateChanged in interface StateChangeEvent.StateChangeHandler
    
    Overrides:
    
    onStateChanged in class AbstractComponentConnector
    
    Parameters:
    
    stateChangeEvent - the state change event with details about the change
  - getWidget
```
public VTree getWidget()
```
    Description copied from class: AbstractComponentConnector
    
    Returns the widget associated with this paintable. The widget returned by this method must not changed during the life time of the paintable.
    
    Specified by:
    
    getWidget in interface ComponentConnector
    
    Overrides:
    
    getWidget in class AbstractComponentConnector
    
    Returns:
    
    The widget associated with this paintable
  - updateNodeFromUIDL
```
public void updateNodeFromUIDL(VTree.TreeNode treeNode,
                               UIDL uidl,
                               int level)
```
  - isReadOnly
```
public boolean isReadOnly()
```
    Description copied from interface: ComponentConnector
    
    Checks if the connector is read only.
    
    Specified by:
    
    isReadOnly in interface ComponentConnector
    
    Overrides:
    
    isReadOnly in class AbstractComponentConnector
    
    Returns:
    
    true
  - getState
```
public TreeState getState()
```
    Description copied from class: AbstractConnector
    
    Returns the shared state object for this connector. Override this method to define the shared state type for your connector.
    
    Specified by:
    
    getState in interface ComponentConnector
    
    Specified by:
    
    getState in interface ServerConnector
    
    Overrides:
    
    getState in class AbstractComponentConnector
    
    Returns:
    
    the current shared state (never null)
  - getTooltipInfo
```
public TooltipInfo getTooltipInfo(com.google.gwt.dom.client.Element element)
```
    Description copied from interface: ComponentConnector
    
    Gets the tooltip info for the given element.
    When overriding this method, ComponentConnector.hasTooltip() should also be overridden to return true in all situations where this method might return a non-empty result.
    
    Specified by:
    
    getTooltipInfo in interface ComponentConnector
    
    Overrides:
    
    getTooltipInfo in class AbstractComponentConnector
    
    Parameters:
    
    element - The element to lookup a tooltip for
    
    Returns:
    
    The tooltip for the element or null if no tooltip is defined for this element.
  - hasTooltip
```
public boolean hasTooltip()
```
    Description copied from interface: ComponentConnector
    
    Check whether there might be a tooltip for this component. The framework will only add event listeners for automatically handling tooltips (using ComponentConnector.getTooltipInfo(Element)) if this method returns true.
    This is only done to optimize performance, so in cases where the status is not known, it's safer to return true so that there will be a tooltip handler even though it might not be needed in all cases.
    
    Specified by:
    
    hasTooltip in interface ComponentConnector
    
    Overrides:
    
    hasTooltip in class AbstractComponentConnector
    
    Returns:
    
    true if some part of the component might have a tooltip, otherwise false
  - sendContextClickEvent
```
protected void sendContextClickEvent(MouseEventDetails details,
                                     com.google.gwt.dom.client.EventTarget eventTarget)
```
    Description copied from class: AbstractComponentConnector
    
    This method sends the context menu event to the server-side. Can be overridden to provide extra information through an alternative RPC interface.
    
    Overrides:
    
    sendContextClickEvent in class AbstractComponentConnector
