如何使标签中的文本在达到一定长度后进入下一行

Question

我正在为学校的一个项目使用PyQt5/python3中的一个小GUI，但是我遇到了文本被切断的问题。使用标签.调整尺寸（）解决不了，我想不出别的办法来解决。我想通过创建一个新标签，或者使用相同的标签，使标签进入一个新的行，这将是更好的。字符的数量，我将有在62个字符的截止，所以我只想创建新的一行，如果标签的文本长度超过62个字符。你知道吗

除了将QLabel的wordWrap属性设置为True之外，还必须使用布局，以便QLabel自动调整QLabel的宽度：

from PyQt5 import QtCore, QtWidgets

class Widget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(Widget, self).__init__(parent)
        self.label_content = QtWidgets.QLabel(
            wordWrap=True,
            alignment=QtCore.Qt.AlignLeft|QtCore.Qt.AlignTop
        )
        self.button_view = QtWidgets.QPushButton("View Database")
        self.input_label = QtWidgets.QLabel("Input:") 
        self.lineedit = QtWidgets.QLineEdit()
        self.ask_button = QtWidgets.QPushButton("Ask Question")

        grid_layout = QtWidgets.QGridLayout(self)
        grid_layout.addWidget(self.label_content)
        grid_layout.addWidget(self.button_view, 0, 1, alignment=QtCore.Qt.AlignTop)
        grid_layout.addWidget(self.input_label, 1, 0, 1, 2)
        grid_layout.addWidget(self.lineedit, 2, 0)
        grid_layout.addWidget(self.ask_button, 2, 1)
        grid_layout.setRowStretch(0, 1)

        self.label_content.setText("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla sollicitudin aliquet mauris quis fringilla. Vivamus scelerisque mauris turpis, a imperdiet purus varius eget. Suspendisse pretium est id augue accumsan, vel luctus purus luctus. In hendrerit, turpis ac ultricies volutpat, urna enim hendrerit nisl, a sagittis arcu justo sit amet elit. Aenean bibendum, lacus nec commodo consequat, tortor lectus pulvinar velit, eu ultrices sem felis eget velit. Curabitur id ipsum sit amet tellus euismod mollis. Vivamus et imperdiet ligula. Donec malesuada fermentum felis, at egestas justo ultrices ac. In quis risus ut odio mattis commodo vel sit amet mauris. Vestibulum rutrum ligula tellus, quis faucibus urna imperdiet at. Praesent fermentum condimentum leo. Phasellus quis lacus sapien. Duis viverra sodales aliquet. Sed volutpat non nibh tincidunt blandit. Sed elementum sem at ligula pharetra hendrerit. Donec vel scelerisque mauris. ")

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication.instance()
    if app is None:
        app = QtWidgets.QApplication(sys.argv)
    w = Widget()
    w.resize(640, 480)
    w.show()
    sys.exit(app.exec_())
