Class CustomLayoutConnector

Constructor Detail

• CustomLayoutConnector

  public CustomLayoutConnector()

Method Detail

• getState

  public CustomLayoutState 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)

• 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 AbstractConnector

• 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)

  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:

  event - the event with information about the hierarchy change

• getWidget

  public VCustomLayout 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 AbstractComponentConnector

  Returns:

  The widget associated with this paintable

• updateCaption

  public void updateCaption​(ComponentConnector paintable)

  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:

  paintable - Child component for which service is requested.

• layout

  public void layout()

  Specified by:

  layout in interface SimpleManagedLayout

• updateFromUIDL

  public void updateFromUIDL​(UIDL uidl,
                             ApplicationConnection client)

  Specified by:

  updateFromUIDL in interface Paintable
