我的代碼有問題：/ 我的程序需要點擊一個QFrame，QWidget或QGroupBox。目前我使用mouseReleaseEvent，但它只適用於我的功能沒有設置值。Qt GUI可點擊Qframe或QWidget或Groupbox

def testc(self,e): 
print(e) 

#when I use this code: 
self.frame.mousePressEvent = self.testc; 
#it's okey 
#but when I'm using 
self.frame.mousePressEvent = self.testc("ssssss"); 
# after starting the function automatically performs a click not working

我怎樣才能讓一個點擊小工具，框架或組盒？

     self.groupBox.setStyleSheet(_fromUtf8("background-color: rgb(56, 30, 255);")) 
     self.groupBox.setObjectName(_fromUtf8("groupBox")) 
     self.label_3 = QtGui.QLabel(self.groupBox) 
     self.label_3.setGeometry(QtCore.QRect(7, 34, 101, 21)) 
     self.label_3.setObjectName(_fromUtf8("label_3")) 

     self.retranslateUi(Form) 
     QtCore.QMetaObject.connectSlotsByName(Form) 

    def retranslateUi(self, Form): 
     Form.setWindowTitle(_translate("Form", "Form", None)) 
     self.label.setText(_translate("Form", "clicable frame", None)) 
     self.label_2.setText(_translate("Form", "click widget", None)) 
     self.groupBox.setTitle(_translate("Form", "GroupBox", None)) 
     self.label_3.setText(_translate("Form", "click groupbox", None))

的一點是，我想要一組對象在我QFrame。點擊QFrame後，我希望我的程序在點擊後寫入。

創建一個不帶參數

你必須分配功能mousePressEvent和self.testc("ssssss")也（可能）不會返回功能的功能。

你可以做的是創造另一個函數

def f(self): 
    return self.testc("ssssss")

，並指定

self.frame.mousePressEvent = self.f

對於這樣的俏皮話經常優選創建拉姆達

self.frame.mousePressEvent = lambda: self.tests("ssssss")
