Şifre Girme İşlemi

Python PyQt
1

Merhaba.

Aşağıdaki gibi bir bankamatik pencerem var.
Kartı tak dediğim zaman şifre girmek için linedit elemanı geliyor ekrana.
Takıldığım nokta her numerik tuş için clicked.connect() mi atamam gerekiyor.
Bunun daha kolay bir yolu var mıdır, nasıl yaparız?

Merhaba, bütün buton nesnelerini bir listede toplayabilirsiniz. Yani mesela şöyle

buton_sayisi = 0
butonlar

for i in range(buton_sayisi):
    butonlar.append(QPushButton())

tıklandığında fonksiyon ataması falan yapmak istiyorsanız aşağıda yazdığım yöntemi de kullanabilirsiniz.


def f(x):
    def t():
        print (x, "den selamlar")
    return t
butonlar = []
for i in range(buton_sayisi):
    btn = QPushButton()
    btn.clicked.connect(f(i))
    butonlar.append(btn)

Belki functools modülünün partial fonksiyonu ile çok daha kolay yapılabilir.

Bu arada incelemek isterseniz önceki zamanlarda yazmış olduğum kodu inceleyebilirsiniz. kod

İyi akşamlar.

(Konudan bağımsız olarak)
Bu arada SSS’e baktım da bu konuyu göremedim. Müsait bir zamanda SSS`e bunu ekleyeyim.

Her tus icin tek bir fonksiyon cagirmaktan daha kolay bir sey dusunemiyorum.
Tuslari bir fonksiyon yardimiyla yaratiyor olsaydik tum koda sadece bir satir eklememiz yetecekti.

@Cihat_Altiparmak’in da gosterdigi gibi fonksiyon kullanmak lazim. Fakat bu noktada functools’a bakmayi tavsiye etmiyorum.

        self.btn1.setMinimumSize(QtCore.QSize(80, 50))
        self.btn1.setMaximumSize(QtCore.QSize(80, 50))

Sunun gibi tekrar eden satirlar yerine self.btnX’i parametre olarak alip bu islemleri yapacak bir setupButton fonksiyonuyla baslanabilir.

Fazlaca buton oluşturduğunuz bir durumda, buton oluşturmanızı sağlayacak bir fonksiyon tanımlamanızda fayda var.
Şöyle bir örnek bırakayım,

Hepsini bir yere doldurmana gerek yok şu şekilde yapabilirsin.

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *


class BankamatikButon(QPushButton):

    def __init__(self, parent):
        super(QWidget, self).__init__(parent.tab)
        self.clicked.connect(self.btn_click)

    def btn_click:
       print("button clicked")

Bu şekilde bir class yaparsan tek yapman gereken BankamatikButon(parent) demen yeterli olur.
super(QWidget, self).__init__(parent.tab) bu satırda tabın içinde olduğu için onu da çağırmam gerekiyorsu sen de de belki böyle gerekebilir ya da denersin, buraya butonun parent nesnesini yolarsın.
