</WRAP>

====== ECBDesktopLanguageChanged ======

Behavior calling onTranslationChanged on ECBehaviorRenderableDesktop if language changed global event is send.

====== Instance Counts ======

This behavior can be used only once on an element.

====== Element Class Properties ======

Element class properties have the prefix ''desktopLanguageChanged.''.

====== Events ======

This behavior has no events.

====== Conversation Commands ======

This behavior adds no conversation commands.

====== Conversation Conditions ======

This behavior adds no conversation conditions.

====== Behavior Tree Actions ======

This behavior adds no behavior tree actions.

====== Behavior Tree Conditions ======

This behavior adds no behavior tree conditions.

====== Required Behaviors ======

  * [[dragengine:modules:dragonscript:behavior_renderabledesktop|ECBehaviorRenderableDesktop]]

====== Optional Behaviors ======

This behavior does not support optional behaviors.

====== API Documentation ======

Since DEMoCap Version ''1.3''

====== Use Cases ======

  * Update widget translation in renderable desktop behavior if language setting changed.

====== Element Class Example ======

Give an example. Has to include at least all behavior dependencies so it should at least prodduce a valid element class.

<code>
class MyElement extends BehaviorElementClass
  public var ECBehaviorComponent component
   public var ECBehaviorCollider collider
   public var ECBehaviorDynamicSkin dynamicSkin
   public var ECBehaviorRenderableDesktop renderableDesktop
   public var ECBDesktopLanguageChanged desktopLanguageChanged
   
   public func new() super("ExampleElement")
     // add required behaviors component and collider
     component = ECBehaviorComponent.new(this)
     collider = ECBehaviorCollider.new(this, component)
     
     // add dynamic skin to modify component
     dynamicSkin = ECBehaviorDynamicSkin.new(this, component)
     
     // create renderable desktop. the skin has to use a renderable named "board".
     // the panel has a size of 1024x1024 and uses gui theme loaded from "adboard.guitheme.xml".
     // the desktop uses by default a stack layout hence all widgets added fill the
     // entire desktop space and are layered ontop of each other. any behavior can
     // change the layout used for the desktop if required
     renderableDesktop = ECBehaviorRenderableDesktop.new(this, dynamicSkin)
     renderableDesktop.getRenderable().setValue("board")
     renderableDesktop.getSize().setPoint(Point.new(512, 256))
     renderableDesktop.getGuiTheme().setPath("/content/ui/adboard.guitheme.xml")

     // here you could now add behaviors adding content to the renderable.
     // the simply have to create (during their init(StubElement) call) one or more widgets
     // adding them to the renderable. using behavior makes this a reusable process
     //
     // MyContentBehavior.new(this, renderableDesktop)
     
     // update translations if language setting changed
     desktopLanguageChanged = ECBDesktopLanguageChanged.new(this, renderableDesktop)
   end
end
</code>

====== Behavior Factory ======

Using element class supporting adding behaviors the behavior can be added like this (again create an example which creates a valid element class):

<code xml>
<?xml version='1.0' encoding='UTF-8'?>
<elementClass name='MyClass' class='GenericBehaviorElement'>
  <behavior type='ECBehaviorComponent'/>
  <behavior type='ECBehaviorCollider'/>
  <behavior type='ECBehaviorDynamicSkin'/>
  <behavior type='ECBehaviorRenderableDesktop'>
    <string name='.renderable'>display</string>
  </behavior>
  
  <behavior type='ECBDesktopLanguageChanged'/>
</elementClass>
</code>
