Constructor Detail

ColorPickerGradientConnector

public ColorPickerGradientConnector()
Method Detail

createWidget

protected Widget createWidget()
Description copied from class: AbstractComponentConnector
Creates and returns the widget for this VPaintableWidget. This method should only be called once when initializing the paintable.

You should typically not override this method since the framework by default generates an implementation that uses GWT#create(Class) to create a widget of the same type as returned by the most specific override of AbstractComponentConnector.getWidget(). If you do override the method, you can't call super.createWidget() since the metadata needed for that implementation is not generated if there's an override of the method.

Overrides:
createWidget in class AbstractComponentConnector
Returns:
a new widget instance to use for this component connector

getWidget

public VColorPickerGradient 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

getState

public com.vaadin.shared.ui.colorpicker.ColorPickerGradientState 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)

onMouseUp

public void onMouseUp(MouseUpEvent event)

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

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
