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 classAbstractConnector
-
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.
-
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 classAbstractComponentConnectorParameters:
stateChangeEvent- the state change event with details about the change
-
layout
public void layout()Specified by:
layoutin interfaceSimpleManagedLayout
-
getWidget
public VAbstractSplitPanel 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 classAbstractComponentConnectorReturns:
The widget associated with this paintable
-
getState
public AbstractSplitPanelState getState()Description copied from class:
AbstractConnectorReturns the shared state object for this connector. Override this method to define the shared state type for your connector.
Specified by:
getStatein interfaceComponentConnectorSpecified by:
getStatein interfaceServerConnectorOverrides:
getStatein classAbstractComponentConnectorReturns:
the current shared state (never null)
-
onConnectorHierarchyChange
public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)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:
event- the event with information about the hierarchy change
