[FIXED] Why setTabOrder didnt work at all? Loopy or single not working

Issue

I tried it in simply one example but i cant figure how to do it. I search like 2-3 hours for figure also even in QtDesigner i cant run it correctly. I also tried with .focusProxy not working

import sys

from PyQt5.QtWidgets import *



class Pencere(QWidget):
    def __init__(self):
        super().__init__()

        self.icayarlar()

    def icayarlar(self):
        self.setWindowTitle("Deneme")

        self.b1=QLineEdit()
        self.b2=QLineEdit()
        self.b3=QLineEdit()

        self.v_box=QHBoxLayout()


        self.v_box.addWidget(self.b1)
        self.v_box.addWidget(self.b2)
        self.v_box.addWidget(self.b3)

        self.setTabOrder(self.b1,self.b3)




        self.setLayout(self.v_box)









app=QApplication(sys.argv)

pencere=Pencere()
pencere.show()

sys.exit(app.exec_())

i also tried this

self.setTabOrder(self.b1,self.b3)
self.setTabOrder(self.b3, self.b2)
self.setTabOrder(self.b2, self.b1)

Solution

Run first setLayout(), then the setTabOrder().

import sys
from PyQt5.QtWidgets import *


class Pencere(QWidget):
    def __init__(self):
        super().__init__()
        self.icayarlar()
        self.show()

    def icayarlar(self):
        self.setWindowTitle("Deneme")
        self.b1=QLineEdit()
        self.b2=QLineEdit()
        self.b3=QLineEdit()
        self.v_box=QHBoxLayout()
        self.v_box.addWidget(self.b1)
        self.v_box.addWidget(self.b2)
        self.v_box.addWidget(self.b3)

        # first setLayout()
        self.setLayout(self.v_box)

        # after setTabOrder()
        self.setTabOrder(self.b1,self.b3)


app = QApplication(sys.argv)
wid = Pencere()
sys.exit(app.exec_())

Hope this helps.
