Constructor Detail

TabsheetConnector

public TabsheetConnector()

Constructs a connector for a TabSheet component.

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 TabsheetBaseConnector

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 TabsheetBaseConnector

Parameters:

stateChangeEvent - the state change event with details about the change

getWidget

public VTabsheet 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 HasWidget

Overrides:

getWidget in class TabsheetBaseConnector

Returns:

The widget associated with this paintable

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.

Specified by:

updateCaption in interface HasComponentsConnector

Parameters:

component - Child component for which service is requested.

layout

public void layout()

Specified by:

layout in interface SimpleManagedLayout

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

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent connector)

Description copied from interface: ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

Called by the framework when the list of child components of the connector implementing this interface has changed. The implementation is responsible for attaching the widgets of any new children and detaching the widgets of any removed children. Implementations should typically also make sure that the child widgets are attached according to the ordering of the child components.

This method is called after the shared state and hierarchy data (i.e. AbstractHasComponentsConnector.setChildComponents(List)) been updated for all affected connectors, but before updating captions, firing state change events, invoking updateFromUIDL for legacy connectors, invoking RPC and starting the layout phase.

Please note that hierarchy change events are fired in a non-deterministic order when a message from the server causes multiple parts of the hierarchy to change. This means that the old parent connector might not yet have detached a child widget and that the widget of a removed child might already have been attached by its new parent.

Specified by:

onConnectorHierarchyChange in interface ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

Parameters:

connector - the event with information about the hierarchy change

renderContent

protected void renderContent()

(Re-)render the content of the active tab.
