                             Component newComponent)

        public void addComponent(Component c,
                         String cssPosition)

        Adds a component to the layout. The component can be positioned by providing a string formatted in CSS-format.

        For example the string "top:10px;left:10px" will position the component 10 pixels from the left and 10 pixels from the top. The identifiers: "top","left","right" and "bottom" can be used to specify the position.

        Parameters:

        c - The component to add to the layout

        cssPosition - The css position string

      • beforeClientResponse

        public void beforeClientResponse(boolean initial)

        Description copied from interface: ClientConnector

        Called before the shared state and RPC invocations are sent to the client. Gives the connector an opportunity to set computed/dynamic state values or to invoke last minute RPC methods depending on other component features.

        Specified by:

        beforeClientResponse in interface ClientConnector

        Overrides:

        beforeClientResponse in class AbstractComponent

        Parameters:

        initial - true if the client-side connector will be created and initialized after this method has been invoked. false if there is already an initialized client-side connector.

      • addLayoutClickListener

        public void addLayoutClickListener(LayoutEvents.LayoutClickListener listener)

        Description copied from interface: LayoutEvents.LayoutClickNotifier

        Add a click listener to the layout. The listener is called whenever the user clicks inside the layout. An event is also triggered when the click targets a component inside a nested layout or Panel, provided the targeted component does not prevent the click event from propagating. A caption is not considered part of a component. The child component that was clicked is included in the LayoutEvents.LayoutClickEvent. Use #removeListener(LayoutClickListener) to remove the listener.

        Specified by:

        addLayoutClickListener in interface LayoutEvents.LayoutClickNotifier

        Parameters:

        listener - The listener to add

                       DesignContext designContext)

        Description copied from interface: Component

        Reads the component state from the given design.

        The component is responsible not only for updating its own state but also for ensuring that its children update their state based on the design.

        It is assumed that the component is in its default state when this method is called. Reading should only take into consideration attributes specified in the design and not reset any unspecified attributes to their defaults.

        This method must not modify the design.

        Specified by:

        readDesign in interface Component

        Overrides:

        readDesign in class AbstractComponent

        Parameters:

        design - The element to obtain the state from

        designContext - The DesignContext instance used for parsing the design

      • writeDesign

        public void writeDesign(org.jsoup.nodes.Element design,
                        DesignContext designContext)

        Description copied from interface: Component

        Writes the component state to the given design.

        The component is responsible not only for writing its own state but also for ensuring that its children write their state to the design.

        This method must not modify the component state.

        Specified by:

        writeDesign in interface Component

        Overrides:

        writeDesign in class AbstractComponent

        Parameters:
