10     def __init__(self, parent=None):

11         super(DynAddObject, self).__init__(parent)

12         addButton = QPushButton(u"添加控件")

13         self.layout = QGridLayout()

14         self.layout.addWidget(addButton, 1, 0)

15         self.setLayout(self.layout)

16         self.connect(addButton, SIGNAL("clicked()"), self.add)

18     def add(self):

19         btncont= self.layout.count()

20         widget = QPushButton(str(btncont), self)

21         self.layout.addWidget(widget)

22 

23 if __name__ == "__main__":

24     app = QApplication(sys.argv)

25     form = DynAddObject()

26     form.show()

27     app.exec_()

 

 

 

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

 1 class DynAddObject(QDialog):

 2     def __init__(self, parent=None):

 3         super(DynAddObject, self).__init__(parent)

 4         addButton = QPushButton(u"添加控件")

 5         self.layout = QGridLayout()

 6         self.layout.addWidget(addButton, 1, 0)

 7         self.setLayout(self.layout)

 8         self.add()

 9 

10     def add(self):

11         self.button={}

12         print(type(self.button))

13         for i in range(1, 8):

14             self.button[i]=QPushButton(str(i))

15             self.layout.addWidget(self.button[i])

16 

17 

18 if __name__ == "__main__":

19     app = QApplication(sys.argv)

20     form = DynAddObject()

21     form.show()

22     app.exec_()

效果：
