从 PyQt5 中的 groupbox 获取标题

在这里阅读：https ://doc.qt.io/qt-5/qgroupbox.html#title-prop

标题：QString

此属性包含组框的标题文本。如果标题包含与符号 ('&') 后跟一个字母，则组框标题文本将具有键盘快捷键。

import sys
from PyQt5 import QtWidgets

class Window(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # creates a QGroupBox
        title = '&Emotion'
        qgroupbox = QtWidgets.QGroupBox(title)
        
        print( type(qgroupbox) )
        print( "title -> {}".format(qgroupbox.title() ) )            # <---

        # sets the margins
        left, top, right, bottom = 10, 10, 10, 10
        self.setContentsMargins(left, top, right, bottom)

        # sets the QGroupBox as the central widget
        self.setCentralWidget(qgroupbox)


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.setWindowTitle('Create a QGroupBox with a title')
    window.resize(400, 400)
    window.show()
    sys.exit(app.exec_())
