Constructor Detail

VgSurfaceView

public VgSurfaceView(Context pContext,
             AttributeSet pAttrs,
             boolean pNeedsTransparency)

Class constructor. Creates a new VgSurfaceView.

Parameters:

pContext - The application context (passed through to Android's GLSurfaceView).

pAttrs - The attributes (passed through to Android's GLSurfaceView).

pNeedsTransparency - Indicates whether transparency (i.e. alpha channel) is needed for this view.

VgSurfaceView

public VgSurfaceView(Context pContext,
             boolean pNeedsTransparency)

Class constructor. Creates a new VgSurfaceView.

Parameters:

pContext - The application context (passed through to Android's GLSurfaceView).

pNeedsTransparency - Indicates whether transparency (i.e. alpha channel) is needed for this view.

Method Detail

drawFrame

public void drawFrame(long pAppCPtr)

setSurfaceSize

public void setSurfaceSize(long pAppCPtr,
                  int pWidth,
                  int pHeight)

dispatchTouchDown

public void dispatchTouchDown(long pAppCPtr,
                     int pX,
                     int pY,
                     int pTouchCount)

dispatchTouchUp

public void dispatchTouchUp(long pAppCPtr,
                   int pX,
                   int pY,
                   int pTouchCount)

dispatchTouchMove

public void dispatchTouchMove(long pAppCPtr,
                     int pX,
                     int pY,
                     int pTouchCount)

dispatchDoubleTouchMove

public void dispatchDoubleTouchMove(long pAppCPtr,
                           int pX,
                           int pY,
                           int pX2,
                           int pY2,
                           int pTouchCount)

pauseRendering

public void pauseRendering()

Pauses the rendering of the VgSurfaceView.

resumeRendering

public void resumeRendering()

Resumes the rendering of the VgSurfaceView. After calling this method, the manipulator will be reset.

requestRedraw

public void requestRedraw()

Requests a single redraw of the VgSurfaceView.

postLoadDataset

public void postLoadDataset()

Called after the dataset has been loaded.

getApplication

public VgIApplication getApplication()

Returns:

The VgIApplication object which provides access to VisioDevKit API.

addOnCreateRunnable

public void addOnCreateRunnable(java.lang.Runnable pRunnable)

Add a runnable task to the VisioDevKit. Will be executed within the onSurfaceCreated() method. This is a good method to add listeners (touch/key) to the VgSurfaceView.

Parameters:

pRunnable - - Runnable to be executed

onResume

public void onResume()

Inform the view that the activity is resumed.

onPause

public void onPause()

Inform the view that the activity is paused.

onDrawFrame

public void onDrawFrame(GL10 gl)

Called to draw the current frame

onSurfaceCreated

public void onSurfaceCreated(GL10 gl,
                    EGLConfig config)

Called when the surface is created or recreated. The drawing context is typically lost and recreated when the activity is paused and resumed. This is a good place to create long-lived OpenGL resources like textures.

onSurfaceChanged

public void onSurfaceChanged(GL10 gl,
                    int width,
                    int height)

Called when the surface changed size. It's a good place to set up your camera here, if it's a fixed camera that doesn't move around the scene.

surfaceDestroyed

public void surfaceDestroyed(SurfaceHolder pHolder)

This method is called immediately before a surface is being destroyed. You should override this method to release/unregister all VisioDevKit objects, and null out as many references on other objects as possible.

onKey

public boolean onKey(View pView,
            int pInt,
            KeyEvent pEvent)

Called when a hardware key is dispatched to a view

onTouch

public boolean onTouch(View pView,
              MotionEvent pEvent)

Called when a touch event is dispatched to a view.
