Question

以下是my .ui file的链接。以下是启动GUI的代码：

import sys
from PyQt4 import QtCore, QtGui
from gui import Ui_Form

class StartQT4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_Form()
        self.ui.setupUi(self)


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())

PY 这是GUI类代码（.py）：

from PyQt4 import phonon

我的问题是，如何让视频播放器加载the url，以便当我切换单选按钮，标记，播放以启动音乐时？
对不起，但我是新手，真的需要这样做。请解释一下，因为我需要稍后在很多其他标签上实现它。另外，PyQt4 Designer中的缩放如何？只需要知道所以我可以为图片制作正确的尺寸。

如果没有详细介绍Phonon软件包如何工作，这里有一个快速片段：

from PyQt4.phonon import Phonon

...

source = Phonon.MediaSource("http://vsyamuzika.narod.ru/tvist/Rock_around_the_clock.mp3")
self.ui.videoPlayer.mediaObject().setCurrentSource(source)
self.ui.videoPlayer.play()

您可以创建一个MediaSource对象列表，并将它们交换到播放器中。

设置Phonon :: VideoPlayer的源代码
