Method Detail

display

public void display(javax.media.opengl.GLAutoDrawable arg0)

Specified by:

display in interface javax.media.opengl.GLEventListener

displayChanged

public void displayChanged(javax.media.opengl.GLAutoDrawable arg0,
                  boolean arg1,
                  boolean arg2)

Specified by:

displayChanged in interface javax.media.opengl.GLEventListener

getComponent

public java.lang.Object getComponent()

Specified by:

getComponent in interface ComponentWrapper

getObserverForRenderer

protected java.awt.image.ImageObserver getObserverForRenderer()

Description copied from class: ViewComponentAdapter

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.

Specified by:

getObserverForRenderer in class ViewComponentAdapter

Returns:

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

getSnapshot

public java.awt.image.RenderedImage getSnapshot()

getView3D

public View3D getView3D()

init

public void init(javax.media.opengl.GLAutoDrawable arg0)

Specified by:

init in interface javax.media.opengl.GLEventListener

initRender

public void initRender(int flags)

Description copied from class: ViewComponentAdapter

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

Specified by:

initRender in class ViewComponentAdapter

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

Overrides:

initView in class ViewComponentAdapter

Parameters:

view - the containing view

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

invokeRender

public void invokeRender(int flags)

Description copied from class: ViewComponentAdapter

Invoked to perform rendering. This method is invoked by ViewComponentAdapter.run() in this ViewComponent's own thread. Its sole task is to invoke ViewComponentAdapter.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 ViewComponentAdapter.invokeRenderSync(int) has completed.

Specified by:

invokeRender in class ViewComponentAdapter

Parameters:

flags - the flags to pass to ViewComponentAdapter.invokeRenderSync(int)

makeSnapshot

public void makeSnapshot(ObjectConsumer<? super java.awt.image.RenderedImage> callback)

Description copied from interface: ViewComponent

Instructs the view component to create a snapshot. The created snapshot has to be delivered to the provided callback as an instance of RenderedImage. This may happen asynchronously, i.e., in an arbitrary thread.

Specified by:

makeSnapshot in interface ViewComponent

Parameters:

callback - callback which asynchronously receives the snapshot

render

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

Description copied from class: ViewComponentAdapter

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

Specified by:

render in class ViewComponentAdapter

Parameters:

flags - combination of bit masks

Throws:

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

reshape

public void reshape(javax.media.opengl.GLAutoDrawable arg0,
           int arg1,
           int arg2,
           int arg3,
           int arg4)

Specified by:

reshape in interface javax.media.opengl.GLEventListener
