MoviePlayer(Movie)

This constructor creates a MoviePlayer object given a QuickTime Movie object.

addedTo(Object)

This method is called by the specified object when the instance of the class that implements this interface is added to the object that is the source of the interest.

getClip()

This method allows you to obtain information describing a MoviePlayer's clipping regions.

getDisplayBounds()

This method is called automatically via the QTCanvas object associated with this client to set the boundary of the movie.

getDuration()

Returns the duration of the media attached to the player.

getGWorld()

QTCanvas calls this method to get the destination QDGraphics of its client.

getInitialSize()

This method returns the original size before the transformations specified in the returned matrix are applied.

getMatrix()

This will return the client's current display transformations

getMovie()

This allows you to access the contained movie controller.

getRate()

Returns the current rate of the player.

getScale()

Returns the time scale of the player - how many ticks per second.

getTime()

Returns the current time value of the object.

getTimeBase()

Returns the TimeBase of the media attached to the player.

getVolume()

Returns the volume setting (0 is silent, 1 is unity gain).

isMuted()

Returns the current mute status.

redraw(Region)

QTCanvas calls this method when the client should redraw itself.

removedFrom(Object)

This method is called by the specified object when the instance of the class that implements this interface is removed from the object that is the source of the interest.

setClip(Region)

This method allows you to set a MoviePlayer's clipping region.

setDisplayBounds(QDRect)

This method is called automatically via the QTCanvas object associated with this client to set the boundary of the movie.

setGWorld(QDGraphics)

QTCanvas calls this method to give the client the QDGraphics object it should use to do its drawing.

setLocation(int, int)

A convenience method to set the position of a QTDrawable object.

setMatrix(Matrix)

This method sets the current matrix of the Transformable object to the new matrix.

setMuted(boolean)

Allows the muting of the specific channel.

setRate(float)

Sets the player to the playback rate.

setTime(int)

Sets the player to the time specified.

setVolume(float)

Sets the volume.

 public MoviePlayer(Movie mov) throws StdQTException

This constructor creates a MoviePlayer object given a QuickTime Movie object.

Parameters:

mov - a Movie object

 public Movie getMovie()

This allows you to access the contained movie controller.

 public void addedTo(Object interest)

This method is called by the specified object when the instance of the class that implements this interface is added to the object that is the source of the interest.

Parameters:

interest - the object that is to be the source of interest for the the object that implements this interface.

 public void removedFrom(Object interest)

This method is called by the specified object when the instance of the class that implements this interface is removed from the object that is the source of the interest.

Parameters:

interest - the object that was the source of interest for the the object that implements this interface.

 public QDGraphics getGWorld() throws StdQTException

QTCanvas calls this method to get the destination QDGraphics of its client.

Returns:

a QDGraphics object or null

 public synchronized void setGWorld(QDGraphics cgp) throws StdQTException

QTCanvas calls this method to give the client the QDGraphics object it should use to do its drawing. If the incoming QDGraphics is the QDGraphics.scratch then the drawable will not be visible and can disable itself. If a client is unable to set the graphics world it should throw an exception.

Parameters:

cgp - a QDGraphics object

 public Dimension getInitialSize() throws QTException

This method returns the original size before the transformations specified in the returned matrix are applied.

 public Matrix getMatrix() throws StdQTException

This will return the client's current display transformations

Returns:

the display transformations of the client

 public void setMatrix(Matrix matrix) throws QTException

This method sets the current matrix of the Transformable object to the new matrix.

 public final synchronized void redraw(Region invalidRgn) throws QTException

QTCanvas calls this method when the client should redraw itself. If the canvas is able to discern that only a part of the client's drawing area needs to be redrawn - then this area shall be passed in using the invalidRgn. Otherwise this will be null in which case the client should redraw itself entirely.

Parameters:

invalidRgn - the invalidRgn that the client should redraw

 public synchronized void setDisplayBounds(QDRect bounds) throws StdQTException

This method is called automatically via the QTCanvas object associated with this client to set the boundary of the movie.

Parameters:

bounds - a QDRect object describing the boundary

 public void setLocation(int x,
                         int y) throws QTException

A convenience method to set the position of a QTDrawable object.

Parameters:

x - the new x location

y - the new y location

 public QDRect getDisplayBounds() throws StdQTException

This method is called automatically via the QTCanvas object associated with this client to set the boundary of the movie.

Parameters:

bounds - a QDRect object describing the boundary

 public void setClip(Region theClip) throws QTException

This method allows you to set a MoviePlayer's clipping region.

Parameters:

theClip - a Region that defines the player's clipping region.

 public Region getClip() throws QTException

This method allows you to obtain information describing a MoviePlayer's clipping regions.

Returns:

the clipping region of the entire MoviePlayer object

 public void setTime(int time) throws StdQTException

Sets the player to the time specified. This time value at this level is a totally arbitrary value - what time that means in "real time" is determined by the implementor of the interface, typically the scale value will determine what a "real" time of 1 second is.

Parameters:

time - the new time value

 public int getTime() throws StdQTException

Returns the current time value of the object.

Returns:

the current time.

 public int getDuration() throws StdQTException

Returns the duration of the media attached to the player. If the player has no media, or does not know the duration of its media it can return the constant kDurationUnknown.

Returns:

the media duration.

 public TimeBase getTimeBase() throws QTException

Returns the TimeBase of the media attached to the player.

Returns:

the players TimeBase.

 public void setRate(float rate) throws StdQTException

Sets the player to the playback rate. Typically a rate of zero will mean that the player is stopped, a positive value that the player is playing forwards, a negative value that the player is playing backwards.

Parameters:

rate - the new playback rate.

 public float getRate() throws StdQTException

Returns the current rate of the player.

Returns:

the playback rate

 public int getScale() throws QTException

Returns the time scale of the player - how many ticks per second.

Returns:

the current scale.

 public float getVolume() throws QTException

Returns the volume setting (0 is silent, 1 is unity gain).

Returns:

a float

 public void setVolume(float val) throws QTException

Sets the volume.

Parameters:

val - the new volume

 public boolean isMuted() throws QTException

Returns the current mute status.

Returns:

a boolean

 public void setMuted(boolean flag) throws QTException

Allows the muting of the specific channel. When unmuted the AudioSpec object will return to its current volume setting.

Parameters:

flag - turn muting on - true or off - false.
