import sys
from PyQt4 import QtGui, QtCore
from PyQt4.QtGui import QLabel app = QtGui.QApplication(sys.argv) label = QLabel()
label.setWindowFlags(QtCore.Qt.FramelessWindowHint) # 无边框
label.setAttribute(QtCore.Qt.WA_TranslucentBackground) # 背景透明
# 打开gif文件
movie = QtGui.QMovie("./icon/waiting.gif")
# 设置cacheMode为CacheAll时表示gif无限循环,注意此时loopCount()返回-1
movie.setCacheMode(QtGui.QMovie.CacheAll)
# 播放速度
movie.setSpeed(100)
label.setMovie(movie)
# 开始播放,对应的是movie.start()
movie.start()
label.show()
sys.exit(app.exec_())
效果如下:
