Method Detail

getState

public com.vaadin.shared.ui.orderedlayout.AbstractOrderedLayoutState 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 AbstractLayoutConnector

Returns:

the current shared state (never null)

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

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)

updateCaption

public void updateCaption(ComponentConnector component)

Description copied from interface: HasComponentsConnector

Update child components caption, description and error message.

Each component is responsible for maintaining its caption, description and error message. In most cases components doesn't want to do that and those elements reside outside of the component. Because of this layouts must provide service for it's childen to show those elements for them.

Parameters:

component - Child component for which service is requested.

getWidget

public VFormLayout 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

getTooltipInfo

public TooltipInfo getTooltipInfo(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
