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的宽度变得越来越窄，文本格式占据多行。基本上我正在寻找一种格式化方法，就像我们调整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()

Answer 1

我最终使用resizeEvent()的{​​{1}}来获取实时标签的宽度值，该值用于格式化标签上的monofont文本：

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()
