PyQt點擊按鈕後顯示文本

我剛開始用幾周前的編程，使用Python。幾天後，我開始使用一些PyQt教程，現在我陷入了一些困境。PyQt點擊按鈕後顯示文本

所以我有一個菜單欄這個窗口。就像Windows資源管理器一樣，例如「File」和子菜單「Exit」。

我想要的是每個按鈕在窗口中顯示不同的文本。就這樣。所以現在當我點擊一個按鈕時，它會進入def並在交互式Python shell上打印一些東西。

def button1(self): 
    print('Button clicked.')

但我想要的是，它顯示在窗口tekst。如果需要的話

    run()

更換print('Button clicked.') 與self.label.setText('Button clicked.') 和點擊後

完整代碼 '按鈕點擊。'文字將會出現，而不是'Dit is het control center van van Andre Jochemsen';
