如何自动格式化QLabel文本

Question

我希望文本自动适应标签内部。 随着QLabel的宽度变得更窄，文本格式占据多行。基本上，我正在寻找一种方法来格式化它，就像在调整Web浏览器窗口大小时格式化HTML文本一样。

label=QtGui.QLabel() 

text = "Somewhere over the rainbow Way up high And the dreams that you dreamed of Once in a lullaby"  

label.setText(text) 
label.show()

我已经结束了使用QLabel的resizeEvent()得到它用于标签的monofont文本格式上飞实时标签的宽度值：

text = "Somewhere over the rainbow Way up high And the dreams that you dreamed of Once in a lullaby..."  

class Label(QtGui.QLabel): 
    def __init__(self, parent=None): 
     super(Label, self).__init__(parent) 

    def resizeEvent(self, event): 
     self.formatText() 
     event.accept() 

    def formatText(self): 
     width = self.width() 
     text = self.text() 
     new = '' 
     for word in text.split(): 
      if len(new.split('\n')[-1])<width*0.1: 
       new = new + ' ' + word 
      else: 
       new = new + '\n' + ' ' + word 
     self.setText(new) 

myLabel = Label() 
myLabel.setText(text) 
myLabel.resize(300, 50) 
font = QtGui.QFont("Courier New", 10) 
font.setStyleHint(QtGui.QFont.TypeWriter) 
myLabel.setFont(font) 
myLabel.formatText() 
myLabel.show()
