python - Changing font for four buttons at once in tkinter -

-

लक्ष्य

मैंने 4 बटन बनाए हैं जो डिफ़ॉल्ट फ़ॉन्ट में हैं टैक्निकर में अब मैंने तय किया है कि सभी चार बटन बहुत छोटा हैं। इसलिए मैं उनमें फ़ॉन्ट के आकार को बढ़ाना चाहता हूं।

समस्या का सामना करना पड़ता है

मैं font = custom को जहां custom = tkFont जोड़ना नहीं चाहता सभी चार बयानों में फ़ॉन्ट (परिवार = 'हेलवेटिका', आकार = '18 ') ।

क्या यह पूरे फ्रेम के लिए ऐसा करने का एक तरीका है कि ये बटन मौजूद हैं? < / P>

कोड 

  f = self.frame कस्टम = फ़ॉन्ट (परिवार = 'हेलवेटिका', आकार = 15) प्रारंभ = बटन (f, text = 'स्टार्ट', कमांड = स्व.स्टार्टरिंग) start.pack (साइड = "टॉप") स्टॉप = बटन (एफ, टेक्स्ट = 'STOP', कमांड = स्व.स्टॉपरिंग) stop.pack (साइड = "टॉप") लैप = बटन (f, text = 'lap', command = self.endlap) lap.pack (side = 'top') रीसेट = बटन (f, text = "RESET", command = self.reset) reset.pack (पक्ष = "शीर्ष") close = बटन (f, text = "QUIT", bg = "black", fg = "red", command = self.quitwin) close.pack (पक्ष = "शीर्ष")  < / पूर्व> 
  कृपया  लक्ष्य को प्राप्त करने के लिए कुछ शॉर्टकट के साथ मेरी सहायता करें और अगर कोई शॉर्टकट नहीं है तो कृपया मुझे भी बताएं!   
 
 
  बटन = [रोक, गोद बटन में बटन के लिए रीसेट, बंद करें] my_font = tkfont.font (परिवार = 'हेलवेटिका', आकार = '18 '): बटन। कॉन्फ़िगर (फ़ॉन्ट = my_font)
