Method Detail
-
init
protected void init()Description copied from class:
AbstractConnectorCalled when the connector has been initialized. Override this method to perform initialization of the connector.
Overrides:
initin classTabsheetBaseConnector
-
onStateChanged
public void onStateChanged(StateChangeEvent stateChangeEvent)Description copied from interface:
StateChangeEvent.StateChangeHandlerNotifies the event handler that the state has changed.
Specified by:
onStateChangedin interfaceStateChangeEvent.StateChangeHandlerOverrides:
onStateChangedin classTabsheetBaseConnectorParameters:
stateChangeEvent- the state change event with details about the change
-
getWidget
public VTabsheet getWidget()Description copied from class:
AbstractComponentConnectorReturns the widget associated with this paintable. The widget returned by this method must not changed during the life time of the paintable.
Specified by:
getWidgetin interfaceHasWidgetOverrides:
getWidgetin classTabsheetBaseConnectorReturns:
The widget associated with this paintable
-
updateCaption
public void updateCaption(ComponentConnector component)Description copied from interface:
HasComponentsConnectorUpdate 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:
updateCaptionin interfaceHasComponentsConnectorParameters:
component- Child component for which service is requested.
-
layout
public void layout()Specified by:
layoutin interfaceSimpleManagedLayout
-
getTooltipInfo
public TooltipInfo getTooltipInfo(com.google.gwt.dom.client.Element element)Description copied from interface:
ComponentConnectorGets the tooltip info for the given element.
When overriding this method,
ComponentConnector.hasTooltip()should also be overridden to returntruein all situations where this method might return a non-empty result.Specified by:
getTooltipInfoin interfaceComponentConnectorOverrides:
getTooltipInfoin classAbstractComponentConnectorParameters:
element- The element to lookup a tooltip forReturns:
The tooltip for the element or null if no tooltip is defined for this element.
-
hasTooltip
public boolean hasTooltip()Description copied from interface:
ComponentConnectorCheck 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
trueso that there will be a tooltip handler even though it might not be needed in all cases.Specified by:
hasTooltipin interfaceComponentConnectorOverrides:
hasTooltipin classAbstractComponentConnectorReturns:
trueif some part of the component might have a tooltip, otherwisefalse
-
onConnectorHierarchyChange
public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent connector)Description copied from interface:
ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandlerCalled 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:
onConnectorHierarchyChangein interfaceConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandlerParameters:
connector- the event with information about the hierarchy change
