以下是我的 .ui 文件的链接。这是启动 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)：

我的问题是，如何让视频播放器加载网址，以便当我切换单选按钮、标记、播放、启动音乐时？
抱歉，但我是新手，确实需要这样做。请解释一下，因为我稍后需要在很多其他选项卡上实现它。另外，PyQt4 Designer 中的缩放比例如何？
只需知道这样我就可以为图片制定正确的尺寸。

Here is the link to my .ui file. And here is the code to start the GUI:

        QtGui.QWidget.__init__(self, parent)

        self.ui.setupUi(self)


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

from PyQt4 import phonon

My question is, how can I get the video player to load the url so that when I toggle the radio button, labeled, play, to start the music?
Sorry, but I am a novice, and really need this to be done. Please explain it since I need to implement it on a lot of other tabs later. Also, how is the scaling in PyQt4 Designer?
Just need to know so I can make the right dimensions for a picture.

无需过多了解 Phonon 包的工作原理，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()

您只需创建一个 MediaSource 对象列表，然后将它们交换到播放器中。

Without getting into TOO much detail about how the Phonon package works, here is a quick snippet:

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()

You can just create a list of MediaSource objects, and swap them into the player.
