Detailed Description

The QMovie class is a convenience class for playing movies with QImageReader.

This class is used to show simple animations without sound. If you want to display video and media content, use the Phonon multimedia framework instead.

First, create a QMovie object by passing either the name of a file or a pointer to a QIODevice containing an animated image format to QMovie's constructor. You can call isValid() to check if the image data is valid, before starting the movie. To start the movie, call start(). QMovie will enter Running state, and emit started() and stateChanged(). To get the current state of the movie, call state().

To display the movie in your application, you can pass your QMovie object to QLabel::setMovie(). Example:

QLabel label;

QMovie *movie = new QMovie("animations/fire.gif");

label.setMovie(movie);

movie->start();

Whenever a new frame is available in the movie, QMovie will emit updated(). If the size of the frame changes, resized() is emitted. You can call currentImage() or currentPixmap() to get a copy of the current frame. When the movie is done, QMovie emits finished(). If any error occurs during playback (i.e, the image file is corrupt), QMovie will emit error().

You can control the speed of the movie playback by calling setSpeed(), which takes the percentage of the original speed as an argument. Pause the movie by calling setPaused(true). QMovie will then enter Paused state and emit stateChanged(). If you call setPaused(false), QMovie will reenter Running state and start the movie again. To stop the movie, call stop().

Certain animation formats allow you to set the background color. You can call setBackgroundColor() to set the color, or backgroundColor() to retrieve the current background color.

currentFrameNumber() returns the sequence number of the current frame. The first frame in the animation has the sequence number 0. frameCount() returns the total number of frames in the animation, if the image format supports this. You can call loopCount() to get the number of times the movie should loop before finishing. nextFrameDelay() returns the number of milliseconds the current frame should be displayed.

QMovie can be instructed to cache frames of an animation by calling setCacheMode().

Call supportedFormats() for a list of formats that QMovie supports.

See also QLabel, QImageReader, and Movie Example.

Member Enumeration Documentation

enum QtGui.QMovie.CacheMode

This enum describes the different cache modes of QMovie.

Enumerator:

CacheAll	All frames are cached.
CacheNone	No frames are cached (the default).

enum QtGui.QMovie.MovieState

This enum describes the different states of QMovie.

Enumerator:

NotRunning	The movie is not running. This is QMovie's initial state, and the state it enters after stop() has been called or the movie is finished.
Paused	The movie is paused, and QMovie stops emitting updated() or resized(). This state is entered after calling pause() or setPaused(true). The current frame number it kept, and the movie will continue with the next frame when unpause() or setPaused(false) is called.
Running	The movie is running.

Member Function Documentation

override void QtGui.QMovie.CreateProxy ( )

virtual

Reimplemented from QtCore.QObject.

new int QtGui.QMovie.CurrentFrameNumber

(

)

Returns the sequence number of the current frame. The number of the first frame in the movie is 0.

new QImage QtGui.QMovie.CurrentImage

(

)

Returns the current frame as a QImage.

See also currentPixmap() and updated().

new QPixmap QtGui.QMovie.CurrentPixmap

(

)

Returns the current frame as a QPixmap.

See also currentImage() and updated().

new void QtGui.QMovie.Dispose

(

)

new int QtGui.QMovie.FrameCount

(

)

Returns the number of frames in the movie.

Certain animation formats do not support this feature, in which case 0 is returned.

new QRect QtGui.QMovie.FrameRect

(

)

Returns the rect of the last frame. If no frame has yet been updated, an invalid QRect is returned.

See also currentImage() and currentPixmap().

new bool QtGui.QMovie.IsValid

(

)

Returns true if the movie is valid (e.g., the image data is readable and the image format is supported); otherwise returns false.

new bool QtGui.QMovie.JumpToFrame

(

int

frameNumber

)

Jumps to frame number frameNumber. Returns true on success; otherwise returns false.

new bool QtGui.QMovie.JumpToNextFrame

(

)

Jumps to the next frame. Returns true on success; otherwise returns false.

new int QtGui.QMovie.LoopCount

(

)

Returns the number of times the movie will loop before it finishes. If the movie will only play once (no looping), loopCount returns 0. If the movie loops forever, loopCount returns -1.

Note that, if the image data comes from a sequential device (e.g. a socket), QMovie can only loop the movie if the cacheMode is set to QMovie::CacheAll.

new int QtGui.QMovie.NextFrameDelay

(

)

Returns the number of milliseconds QMovie will wait before updating the next frame in the animation.

new void QtGui.QMovie.OnError ( QImageReader.ImageReaderError  error )

protected

This signal is emitted by QMovie when the error error occurred during playback. QMovie will stop the movie, and enter QMovie::NotRunning state.

new void QtGui.QMovie.OnFinished ( )

protected

This signal is emitted when the movie has finished.

See also QMovie::stop().

new void QtGui.QMovie.OnFrameChanged ( int  frameNumber )

protected

This signal is emitted when the frame number has changed to frameNumber. You can call currentImage() or currentPixmap() to get a copy of the frame.

This function was introduced in Qt 4.1.

new void QtGui.QMovie.OnResized ( QSize  size )

protected

This signal is emitted when the current frame has been resized to size. This effect is sometimes used in animations as an alternative to replacing the frame. You can call currentImage() or currentPixmap() to get a copy of the updated frame.

new void QtGui.QMovie.OnStarted ( )

protected

This signal is emitted after QMovie::start() has been called, and QMovie has entered QMovie::Running state.

new void QtGui.QMovie.OnStateChanged ( QMovie.MovieState  state )

protected

This signal is emitted every time the state of the movie changes. The new state is specified by state.

See also QMovie::state().

new void QtGui.QMovie.OnUpdated ( QRect  rect )

protected

This signal is emitted when the rect rect in the current frame has been updated. You can call currentImage() or currentPixmap() to get a copy of the updated frame.

new void QtGui.QMovie.SetPaused

(

bool

paused

)

If paused is true, QMovie will enter Paused state and emit stateChanged(Paused); otherwise it will enter Running state and emit stateChanged(Running).

See also paused() and state().

new void QtGui.QMovie.Start

(

)

Starts the movie. QMovie will enter Running state, and start emitting updated() and resized() as the movie progresses.

If QMovie is in the Paused state, this function is equivalent to calling setPaused(false). If QMovie is already in the Running state, this function does nothing.

See also stop() and setPaused().

new QMovie.MovieState QtGui.QMovie.State

(

)

Returns the current state of QMovie.

See also MovieState and stateChanged().

new void QtGui.QMovie.Stop

(

)

Stops the movie. QMovie enters NotRunning state, and stops emitting updated() and resized(). If start() is called again, the movie will restart from the beginning.

If QMovie is already in the NotRunning state, this function does nothing.

See also start() and setPaused().

static System.Collections.Generic.List<QByteArray> QtGui.QMovie.SupportedFormats ( )

static

Returns the list of image formats supported by QMovie.

This function was introduced in Qt 4.1.

See also QImageReader::supportedImageFormats().

Property Documentation

new QColor QtGui.QMovie.BackgroundColor

getset

Returns the background color of the movie. If no background color has been assigned, an invalid QColor is returned.

For image formats that support it, this function sets the background color to color.

new CacheMode QtGui.QMovie.cacheMode

getset

This property holds the movie's cache mode.

Caching frames can be useful when the underlying animation format handler that QMovie relies on to decode the animation data does not support jumping to particular frames in the animation, or even "rewinding" the animation to the beginning (for looping). Furthermore, if the image data comes from a sequential device, it is not possible for the underlying animation handler to seek back to frames whose data has already been read (making looping altogether impossible).

To aid in such situations, a QMovie object can be instructed to cache the frames, at the added memory cost of keeping the frames in memory for the lifetime of the object.

By default, this property is set to CacheNone.

new QIODevice QtGui.QMovie.Device

getset

Returns the device QMovie reads image data from. If no device has currently been assigned, 0 is returned.

Sets the current device to device. QMovie will read image data from this device when the movie is running.

new IQMovieSignals QtGui.QMovie.Emit

getprotected

Slot<QImageReader.ImageReaderError> QtGui.QMovie.Error

addremove

This signal is emitted by QMovie when the error error occurred during playback. QMovie will stop the movie, and enter QMovie::NotRunning state.

new string QtGui.QMovie.FileName

getset

Returns the name of the file that QMovie reads image data from. If no file name has been assigned, or if the assigned device is not a file, an empty QString is returned.

Sets the name of the file that QMovie reads image data from, to fileName.

Slot QtGui.QMovie.Finished

addremove

This signal is emitted when the movie has finished.

See also QMovie::stop().

new QByteArray QtGui.QMovie.Format

getset

Returns the format that QMovie uses when decoding image data. If no format has been assigned, an empty QByteArray() is returned.

Sets the format that QMovie will use when decoding image data, to format. By default, QMovie will attempt to guess the format of the image data.

You can call supportedFormats() for the full list of formats QMovie supports.

Slot<System.Int32> QtGui.QMovie.FrameChanged

addremove

This signal is emitted when the frame number has changed to frameNumber. You can call currentImage() or currentPixmap() to get a copy of the frame.

This function was introduced in Qt 4.1.

Slot<QSize> QtGui.QMovie.Resized

addremove

This signal is emitted when the current frame has been resized to size. This effect is sometimes used in animations as an alternative to replacing the frame. You can call currentImage() or currentPixmap() to get a copy of the updated frame.

new QSize QtGui.QMovie.ScaledSize

getset

Returns the scaled size of frames.

This function was introduced in Qt 4.1.

Sets the scaled frame size to size.

This function was introduced in Qt 4.1.

new int QtGui.QMovie.Speed

getset

This property holds the movie's speed.

The speed is measured in percentage of the original movie speed. The default speed is 100%. Example:

QMovie movie("racecar.gif");

movie.setSpeed(200); // 2x speed

Slot QtGui.QMovie.Started

addremove

This signal is emitted after QMovie::start() has been called, and QMovie has entered QMovie::Running state.

Slot<QMovie.MovieState> QtGui.QMovie.StateChanged

addremove

This signal is emitted every time the state of the movie changes. The new state is specified by state.

See also QMovie::state().

new QMetaObject QtGui.QMovie.StaticMetaObject

staticget

Slot<QRect> QtGui.QMovie.Updated

addremove

This signal is emitted when the rect rect in the current frame has been updated. You can call currentImage() or currentPixmap() to get a copy of the updated frame.
