                      java.awt.Color old)

getColor

public static java.awt.Color getColor(Tuple3f c,
                      java.awt.Color old)

getFactory

public Item getFactory()

Description copied from interface: ViewComponent

Returns the factory item which has been set by ViewComponent.initFactory(Item), i.e., the item which created this component.

Specified by:

getFactory in interface ViewComponent

Returns:

factory item of this component

getFontMetrics

public java.awt.FontMetrics getFontMetrics(java.awt.Font font)

getGlobalLOD

public int getGlobalLOD()

Description copied from interface: ViewComponent

Determines the global level-of-detail which should currently be used in this view component. The value lies between View.LOD_MIN and View.LOD_MAX inclusively.

Specified by:

getGlobalLOD in interface ViewComponent

Returns:

global level-of-detail

getIntColor

public static int getIntColor(Tuple3f c)

getInterruptedException

public java.lang.InterruptedException getInterruptedException()

getObserverForRenderer

protected abstract java.awt.image.ImageObserver getObserverForRenderer()

Returns an observer which receives the information about the rendered image from a Renderer. The returned observer has to manage the drawing of the (partially) rendered image on the view component.

Returns:

an observer receiving the image, or null if this is not supported by this component

getOption

public java.lang.Object getOption(java.lang.String name,
                         java.lang.Object defaultValue)

getRenderGraphState

public GraphState getRenderGraphState()

getView

public View getView()

initFactory

public void initFactory(Item factory)

Description copied from interface: ViewComponent

Sets the factory item which created this view component.

Specified by:

initFactory in interface ViewComponent

Parameters:

factory - factory item

initRender

protected abstract void initRender(int flags)

Performs initialization tasks in preparation for rendering. This method is invoked by run() in this ViewComponent's own thread.

Parameters:

flags - combination of bit masks

initView

public void initView(View view,
            EventListener listener)

Description copied from interface: ViewComponent

Initializes this component. This method sets the view within which this view component is used to display the graph. It also sets an event listener. this has to be informed of mouse and keys events within the view component by implementations of this method.

Specified by:

initView in interface ViewComponent

Parameters:

view - the containing view

listener - mouse and key events will be reported to this listener

installListeners

protected void installListeners(java.awt.Component canvas)

invokeRender

protected abstract void invokeRender(int flags)

Invoked to perform rendering. This method is invoked by run() in this ViewComponent's own thread. Its sole task is to invoke invokeRenderSync(int) in the rendering thread (which may be this ViewComponent's thread, the AWT-thread, or another thread, depending on the implementation) in a write-protected context. The invocation has to be synchronously, i.e., if it is in another thread, the current thread has to wait until invokeRenderSync(int) has completed.

Parameters:

flags - the flags to pass to invokeRenderSync(int)

invokeRenderSync

protected void invokeRenderSync(int flags)

Invokes render(int), ensuring that Workbench.current() returns the correct workbench. If render(int) throws an InterruptedException, a repaint is posted. The write-lock of this view's graph has to be acquired by the invoker (see Lockable).

Parameters:

flags - the flags to pass to render(int)

optionValueChanged

protected void optionValueChanged(java.lang.String name,
                      java.lang.Object object)

render

protected abstract void render(int flags)
                        throws java.lang.InterruptedException

Performs rendering. This method is invoked by invokeRenderSync(int) in a context where Workbench.current() returns the workbench of this view.

Parameters:

flags - combination of bit masks

Throws:

java.lang.InterruptedException - if the rendering has been interrupted

render

public void render(Renderer r)

Description copied from interface: ViewComponent

Initiates a rendering of the graph using the specified renderer.

Specified by:

render in interface ViewComponent

render

public void render(Renderer r,
          int width,
          int height)

Specified by:

render in interface ViewComponent

renderUninterruptibly

protected void renderUninterruptibly()

repaint

public void repaint(int flags)

Description copied from interface: ViewComponent

Initiates a repaint of those parts of the view which are indicated by the flags, interpreted as a combination of bit masks. This method may be invoked from arbitrary threads.

Specified by:

repaint in interface ViewComponent

Parameters:

flags - the parts to be repainted

run

public final void run()

Controls rendering and the global level of detail in an own thread. This method should not be invoked by user code.

Specified by:

run in interface java.lang.Runnable

toSelection

public Selection toSelection(Context ctx)

Description copied from interface: Selectable

Converts this object into a Selection.

Specified by:

toSelection in interface Selectable

Parameters:

ctx - the UI context

Returns:

a selection, or null if this is not possible
