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)
17 
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：
