Popup PySide：更改窗口的大小/增长方向

我在窗口边缘创建了一个弹出窗口，我希望它在用户输入文本字段时扩展弹出窗口。这目前可以工作，但窗口正在向右扩展。相反，我希望弹出窗口向左扩展（并将右边缘固定在适当的位置）

下面是我最接近的工作示例。在它里面，我得到了每个文本输入的弹出窗口的大小，然后根据它的新大小移动弹出窗口。我觉得这应该行得通，但不行

在第一次输入文本时，弹出窗口跳到我的屏幕的左边缘（仅x变换）。在第二次文本输入时，弹出窗口跳回其原始位置。在第三个文本输入时，弹出窗口跳回屏幕的左边缘。在第四个输入上。。。你明白了。我还想提到的是，窗口的整体增长看起来是从弹出窗口的中心开始的，而不是从右边缘开始的

我注意到，在点击按钮后，它会一直高亮显示，直到我的鼠标经过它。这会导致这个问题吗

任何想法或更好的方式来实现这一效果将是伟大的，谢谢

我已经对您在OP中提供的代码进行了一点修改，并尝试结合一个示例来解决您的特定问题

我对代码所做的一些修改：

• 在

  弹出窗口的
  resizeEvent
  内触发
  移动UI
  
  修正了
  弹出窗口
  中的
  移动UI
  方法，使弹出窗口不会从一个位置闪烁到另一个位置
  直接在
  弹出窗口中移动
  事件过滤器
  
  合并了处理按钮事件的函数。在
  Tool\u窗口中单击。连接
  
  

解决方案并不完美，当弹出窗口在Ubuntu中扩展和移动时，仍然会有一些“闪烁”。然而，这在Windows7中不是很明显。如果我想到另一个解决方案，我会做一个更新

这导致：

更新（2015-07-30）：弹出窗口缩小到内容的宽度 我已经扩展了这个示例，现在弹出窗口的最小值为100，当文本宽度超过这个值时，这个值会扩展。此外，如果删除文本，弹出窗口的宽度将缩小到最小值100

---

这是通过在内容更改时计算

QLineEdit

中文本的宽度，并使用该值为方法

line\u edit\u text\u changed

中的弹出窗口指定一个固定宽度来完成的。这真是个好答案！非常感谢您抽出时间做这件事this@MikeBourbeau谢谢你竖起大拇指。如果您感兴趣，我很好奇如何将弹出窗口缩小到

QLineEdit

的内容。我已经在示例中添加了这样做的代码。不过，我还没有对它进行全面测试。
