Method Detail

updateFromUIDL

public void updateFromUIDL(UIDL uidl,
                           ApplicationConnection client)

This method must be implemented to update the client-side component from UIDL data received from server. This method is called when the page is loaded for the first time, and every time UI changes in the component are received from the server.

Specified by:

updateFromUIDL in interface Paintable

getWidget

public VMenuBar 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.menubar.MenuBarState 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)

layout

public void layout()

Specified by:

layout in interface SimpleManagedLayout

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
