解决方案1: 还没有尝试过PyQt版本但是你去了: https://github.com/ertanguven/desktop-service/blob/master/pds/qprogressindicator.py
基于:https://github.com/mojocorp/QProgressIndicator
解决方案2: 使用QMovie加载.gif文件
class ImagePlayer(QtGui.QWidget):
def __init__(self, filename, title, parent=None):
QtGui.QWidget.__init__(self, parent)
# Load the file into a QMovie
self.movie = QtGui.QMovie(filename, QByteArray(), self)
size = self.movie.scaledSize()
self.setGeometry(200, 200, size.width(), size.height())
self.setWindowTitle(title)
self.movie_screen = QtGui.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 = QtGui.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()
def run():
global my_window
try:
my_window.close()
my_window.deleteLater()
except: pass
my_window = ImagePlayer(r'Path/To/loader.gif', "Hello")
my_window.show()
run()
