从PyQt4切换到PySide

Question

我正在使用PyCharm并使用MacPorts导入PyQt4。我从Youtube API页面获得了HTML代码。我从这个网站得到另一半：https://wiki.python.org/moin/PyQt/Embedding%20Widgets%20in%20Web%20Pages。

这两个代码组合在一起：

import sys
from PyQt4.QtCore import QSize, Qt
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *

html = \
"""<iframe id="existing-iframe-example"
        width="640" height="360"
        src="https://www.youtube.com/embed/DjCO41GMiRg?enablejsapi=1"
        frameborder="0"
        style="border: solid 4px #37474F"
></iframe>

<script type="text/javascript">
  var tag = document.createElement('script');
  tag.id = 'iframe-demo';
  tag.src = 'https://www.youtube.com/iframe_api';
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('existing-iframe-example', {
        events: {
          'onReady': onPlayerReady,
          'onStateChange': onPlayerStateChange
        }
    });
  }
  function onPlayerReady(event) {
    document.getElementById('existing-iframe-example').style.borderColor = '#FF6D00';
  }
  function changeBorderColor(playerStatus) {
    var color;
    if (playerStatus == -1) {
      color = "#37474F"; // unstarted = gray
    } else if (playerStatus == 0) {
      color = "#FFFF00"; // ended = yellow
    } else if (playerStatus == 1) {
      color = "#33691E"; // playing = green
    } else if (playerStatus == 2) {
      color = "#DD2C00"; // paused = red
    } else if (playerStatus == 3) {
      color = "#AA00FF"; // buffering = purple
    } else if (playerStatus == 5) {
      color = "#FF6DOO"; // video cued = orange
    }
    if (color) {
      document.getElementById('existing-iframe-example').style.borderColor = color;
    }
  }
  function onPlayerStateChange(event) {
    changeBorderColor(event.data);
  }
</script>

从PyQt4切换到PySide

我也有这个问题，我想我可能会有答案。 PyQt4不是用Python开发Qt应用程序的唯一选择，还有PySide。

您可以通过pip安装它： pip install -U PySide

或程序包管理器（如果使用Linux）： sudo apt-get install python-pyside 或对于python3： sudo apt-get install python3-pyside

安装完成后，将PyQt4导入替换为：

from PySide.QtCore import QSize, Qt
from PySide.QtGui import *
from PySide.QtWebKit import *

所有内容和功能应完全相同，希望YouTube能够正常运行。

另一个好处是PySide拥有LGPL许可证，而PyQt4拥有GPL许可证，因此，在使用PySide时，您不必释放程序的源代码。

当我使用PyQt时，我的嵌入式YouTube视频无法显示
