Class FocusModelImpl

java.lang.Object

info.magnolia.ui.vaadin.gwt.client.editor.model.focus.FocusModelImpl

All Implemented Interfaces:

FocusModel

public class FocusModelImpl
extends Object
implements FocusModel

Takes care of toggling the visibility of the control-bars in the page-editor based on selections of the elements. This is a fairly optimized and complex implementation considering lots of special corner-cases and side-effects. Don't apply changes here lightly. Seriously. This class should remain state-less. Ideally it should only contain the logic for switching the visibility of control-bars inside the iframe.

Method Detail

selectElement

public void selectElement(com.google.gwt.dom.client.Element element)

Specified by:

selectElement in interface FocusModel

selectElement

public void selectElement(AbstractElement element)

Specified by:

selectElement in interface FocusModel

init

public void init()

Creates the initial selection of the page-editor when in editing-mode:

     

         
Root-areas are visible
         
Component-placeholders in the root-areas are visible.
     
 

Opposed to togglePageFocus(boolean) this method only needs to be called once, when the iframe is loaded. The reason is that these settings will never be reset by any selections done afterwards.

Specified by:

init in interface FocusModel

resetFocus

public void resetFocus()

Resets the last selected elements. This needs to happen as lot's of the toggling-logic of the displayed bars and their status is based on these. It has no visual effect. This method should ideally go, as the selected elements should automatically be disposed, when the dom changes, e.g. when the iframe reloads.
