Detailed Description

Builds a graph.

Attributes

• align: Boolean, see GrasylaScene#isAlignWidgets()
• animate: Boolean, see GrasylaScene#isAnimate()

Contents

The contents are evaluated as RootWidget and added into the scene.

Result

A Scene if a Widget is asked. Otherwise, a JComponent containing the created scene.

void metadone.client.grasyla2.visuallibrary.GraphEngine.building_hook

(

boolean

go

)

[protected]

Called when building of the components is started or stopped.

Parameters:

go	true indicates that the process is started, otherwise it is false

Reimplemented from metadone.client.grasyla2.GrasylaEngine.

protected<C> Component<? extends C> metadone.client.grasyla2.visuallibrary.GraphEngine.buildNewComponent

(

Class< C >

clComp

)

throws BadPreCondition [package, virtual]

Builds a new component.

Parameters:

<C>	The type
clComp	The class

Returns:

The new component

Exceptions:

void metadone.client.grasyla2.visuallibrary.GraphEngine.disposeInternal

(

)

[protected]

Called by dispose().

It is called after clearing the children, the goal is to let subtypes clear their internal variables when disposing.

static GrasylaScene metadone.client.grasyla2.visuallibrary.GraphEngine.getScene

(

GrasylaContext

context

)

[static]

Gets the scene from a context.

If the context does not contain a scene, the parents are searched.

Parameters:

context

The context

Returns:

The scene

Exceptions:

IllegalArgumentException

when a context was not found
