Python隱藏標籤和事件按鈕

Question

我想隱藏我的標籤和按鈕，當有人按下按鈕，但我有我的代碼中的問題，我不能訪問標籤變量，我不知道如何隱藏也許它與此代碼？：

setStyleSheet("display: none;") 

這裏工作是我的代碼，不工作我磨片按下按鈕蟒蛇PROGRAMM說不迴應

也許有人爲能幫助我。

EDIT1： 當我做，所以

def spielen(self, event,): 
     print("spielen") 
     self.label1 = QtWidgets.QLabel(self) 
     self.label1.hide() 

比我得到的控制檯消息spielen但標籤仍然存在 當我願意這樣做：

def spielen(self, event,): 
    print("spielen") 
    self.label1.hide() 

比程序崩潰

如果你想引用你已經在類中創建對象時，你需要將其聲明爲這個類的一個屬性，與self.labelX：

self.label1 = QtWidgets.QLabel(self) 

然後在這個類中的任何方法，你可以方便地調用這個屬性：

self.label1.hide() 

或其他地方的日E碼

window_inhalt_instance.label1.hide()

編輯： 我專注於你如何實例化類，你需要在這裏改變一些地方過於：

標籤不隱藏，因爲它們被創建與WindowInhalt.label(self)

當你的類窗口從WindowInhalt繼承，你可以直接叫

self.label() # in initme(), same for the buttons 

但你需要更改WindowInhalt每個標籤聲明，通過添加自
