example.photoalbum .PhotoFrame

PhotoFrame
class PhotoFrame extends Canvas implements Runnable(Code)
	This PhotoFrame provides the picture frame and drives the animation of the frames and the picture. It handles the starting and stopping of the Animation and contains the Thread used to do the timing and requests that the Canvas be repainted periodically. It controls the border style and animation speed.

Field Summary
int	frameCount
int	frameRate

Constructor Summary
	PhotoFrame() Create a new PhotoFrame.

Method Summary
int	getSpeed() Get the speed at which animation occurs.
int	getStyle() Get the style being used for borders.
protected void	hideNotify() Notified when the Canvas is no longer visible.
boolean	intersectsClip(Graphics g, int x, int y, int w, int h) Return true if the specified rectangle does not intersect the clipping rectangle of the graphics object.
protected void	keyPressed(int keyCode) Handle key events.
protected void	keyRepeated(int keyCode) Handle key repeat events as regular key events.
void	next() Advance to the next image and wrap around if necessary.
protected void	paint(Graphics g) Paint is called whenever the canvas should be redrawn.
void	previous() Back up to the previous image.
void	reset() Reset the PhotoFrame so it holds minimal resources.
public void	run() Runs the animation and makes the repaint requests.
void	setImages(Vector images) Set the array of images to be displayed.
void	setSpeed(int speed) Set the animation speed.
void	setStyle(int style) Set the frame style.
protected void	showNotify() Notified when Canvas is made visible.

Field Detail

frameCount
int frameCount(Code)
	Number of frames since last frame rate report

frameRate
int frameRate(Code)
	Last reported frame rate (for re-paint)

Constructor Detail

PhotoFrame
PhotoFrame()(Code)
	Create a new PhotoFrame. Create an offscreen mutable image into which the border is drawn. Border style is none (0). Speed is stopped (0) until set.

Method Detail

getSpeed
int getSpeed()(Code)
	Get the speed at which animation occurs. the current speed. See Also: setSpeed

getStyle
int getStyle()(Code)
	Get the style being used for borders. the style.

hideNotify
protected void hideNotify()(Code)
	Notified when the Canvas is no longer visible. Signal the running Thread that it should stop.

intersectsClip
boolean intersectsClip(Graphics g, int x, int y, int w, int h)(Code)
	Return true if the specified rectangle does not intersect the clipping rectangle of the graphics object. If it returns true then the object must be drawn otherwise it would be clipped completely. The checks are done Parameters: g - the Graphics context to check. Parameters: x - the x value of the upper left corner of the rectangle Parameters: y - the y value of the upper left corner of the rectangle Parameters: w - the width of the rectangle Parameters: h - the height of the rectangle true if the rectangle intersects the clipping region

keyPressed
protected void keyPressed(int keyCode)(Code)
	Handle key events. FIRE events toggle between running and stopped. LEFT and RIGHT key events when stopped show the previous or next image. Parameters: keyCode - of the key pressed

keyRepeated
protected void keyRepeated(int keyCode)(Code)
	Handle key repeat events as regular key events. Parameters: keyCode - of the key repeated

next
void next()(Code)
	Advance to the next image and wrap around if necessary.

paint
protected void paint(Graphics g)(Code)
	Paint is called whenever the canvas should be redrawn. It clears the canvas and draws the frame and the current current frame from the animation. Parameters: g - the Graphics context to which to draw

previous
void previous()(Code)
	Back up to the previous image. Wrap around to the end if at the beginning.

reset
void reset()(Code)
	Reset the PhotoFrame so it holds minimal resources. The animation thread is stopped.

run
public void run()(Code)
	Runs the animation and makes the repaint requests. The thread will exit when it is no longer the current Animation thread.

setImages
void setImages(Vector images)(Code)
	Set the array of images to be displayed. Update the width and height of the image and draw the border to fit around it in the offscreen image. Parameters: images - a vector of images to be displayed.

setSpeed
void setSpeed(int speed)(Code)
	Set the animation speed. Speed: 0 = stop 1 = slow 2 = medium 3 = fast 4 = unlimited Parameters: speed - speedo of animation 0-3;

setStyle

void setStyle(int style)(Code)

Set the frame style. Recreate the photo frame image from the current style and location and size

Style:

Style 0: No border is drawn.
Style 1: A simple border is drawn
Style 2: The border is outlined and an image is created to tile within the border.

Parameters:
style - the style of the border; 0 = none, 1 = simple,2 = fancy.

showNotify
protected void showNotify()(Code)
	Notified when Canvas is made visible. If there is more than one image to display create the thread to run the animation timing.
