[−][src]Struct qt_gui::QMovie

#[repr(C)]pub struct QMovie { /* fields omitted */ }

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

C++ class: QMovie.

C++ documentation:

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 Qt Multimedia 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.

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.

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().
