PyQt QMovie不会循环GIF

Question

我有一个播放 gif 的工作示例，但它并没有循环GIF。即使我改变了 movie.setCacheMode（QMovie.CacheAll）

任何想法？ - ＆gt;动画Gif

import sys

class ImagePlayer(QWidget):
    def __init__(self, filename, title, parent=None):
        QWidget.__init__(self, parent)

        # Load the file into a QMovie
        self.movie = QMovie(filename, QByteArray(), self)

        size = self.movie.scaledSize()
        self.setGeometry(200, 200, size.width(), size.height())
        self.setWindowTitle(title)

        self.movie_screen = QLabel()
        # Make label fit the gif
        self.movie_screen.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding)
        self.movie_screen.setAlignment(Qt.AlignCenter)

        # Create the layout
        main_layout = QVBoxLayout()
        main_layout.addWidget(self.movie_screen)

        self.setLayout(main_layout)

        # Add the QMovie object to the label
        self.movie.setCacheMode(QMovie.CacheAll)
        self.movie.setSpeed(100)
        self.movie_screen.setMovie(self.movie)
        self.movie.start()
        self.movie.loopCount()


if __name__ == "__main__":
    gif = "dotGreen.gif"
    app = QApplication(sys.argv)
    player = ImagePlayer(gif, "was")
    player.show()
    sys.exit(app.exec_())

Answer 1

实际上 gif 之前已使用循环选项播放保存。因此将其更改为＆＃34; 永远＆＃34;做了伎俩。
