CheckBoxGroupConnector

public CheckBoxGroupConnector()

Method Detail

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 AbstractFocusableListingConnector<VCheckBoxGroup>

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

setDataSource

public void setDataSource(DataSource<elemental.json.JsonObject> dataSource)

Description copied from interface: HasDataSource

Sets the data source for this Connector.

Specified by:

setDataSource in interface HasDataSource

Overrides:

setDataSource in class AbstractListingConnector

Parameters:

dataSource - the new data source, not null

getState

public CheckBoxGroupState 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 AbstractListingConnector

Returns:

the current shared state (never null)

isRequiredIndicatorVisible

public boolean isRequiredIndicatorVisible()

Description copied from interface: HasRequiredIndicator

Checks if a required indicator should be shown for the given connector.

Specified by:

isRequiredIndicatorVisible in interface HasRequiredIndicator

Overrides:

isRequiredIndicatorVisible in class AbstractFieldConnector

Returns:

true to show an indicator, false otherwise

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
