protected abstract boolean isResolutionMonthOrHigher()

Returns true is the current resolution of the widget is month or less specific (e.g. month, year, quarter, etc).

Returns:

true if the current resolution is above month

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 HasWidget

Overrides:

getWidget in class AbstractTextualDateConnector<R extends Enum<R>>

Returns:

The widget associated with this paintable

Overrides:

getState in class AbstractTextualDateConnector<R extends Enum<R>>

Returns:

the current shared state (never null)

onStateChanged

public void onStateChanged(StateChangeEvent stateChangeEvent)

Description copied from interface: StateChangeEvent.StateChangeHandler
