或者通过赋值self.object={}字典，将字典dict的每一个值赋值为QPushButton

class DynAddObject(QDialog):
    def __init__(self, parent=None):
        super(DynAddObject, self).__init__(parent)
        addButton = QPushButton(u"添加控件")
        self.layout = QGridLayout()
        self.layout.addWidget(addButton, 1, 0)
        self.setLayout(self.layout)
        self.add()

    def add(self):
        self.button={}
        print(type(self.button))
        for i in range(1, 8):
            self.button[i]=QPushButton(str(i))
            self.layout.addWidget(self.button[i])


if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = DynAddObject()
    form.show()
    app.exec_()
