Tabs added before app.exec_() is called look and act as any other tabs u met, though if adding another after the app.exec_() call makes the new tab 'detach' from the main app window. Pic below :)
Why? How can I make it move inside the window?
import threading
import time
import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWidgets import QFormLayout
from PyQt5.QtWidgets import QLineEdit
from PyQt5.QtWidgets import QTabWidget

class ATry(threading.Thread):
def __init__(self):
super().__init__()
def run(self):
time.sleep(1)
anotherTextEdit = QTextEdit()
anotherLineEdit = QLineEdit()
anotherLayout = QFormLayout()
anotherLayout.addRow(anotherTextEdit)
anotherLayout.addRow(anotherLineEdit)
anotherTab = QWidget()
anotherTab.setLayout(anotherLayout)
md.addTab(anotherTab, "Outside")
app = QApplication(sys.argv)
md = QTabWidget()
aTextEdit = QTextEdit()
aLineEdit = QLineEdit()
layout = QFormLayout()
layout.addRow(aTextEdit)
layout.addRow(aLineEdit)
thisTab = QWidget()
thisTab.setLayout(layout)
md.addTab(thisTab, "Inside")
a = ATry()
a.start()
md.show()
app.exec_()

It works with QTimer or signals:

super().__init__()
self.pointer = pointer
def run(self):
time.sleep(2)
self.pointer.emit()
def addTheTab():
anotherTextEdit = QTextEdit()
anotherLineEdit = QLineEdit()
anotherLayout = QFormLayout()
anotherLayout.addRow(anotherLineEdit)
anotherLayout.addRow(anotherTextEdit)
anotherTab = QWidget()
anotherTab.setLayout(anotherLayout)
md.addTab(anotherTab, "Whatever")
class MyQObject(QObject):
trigger = pyqtSignal()
def __init__(self):
super().__init__()
def connect_and_get_trigger(self):
self.trigger.connect(addTheTab)
return self.trigger
def getGFX(self):
app = QApplication(sys.argv)
md = QTabWidget()
md.show()
return app, md
obj = MyQObject()
app, md = obj.getGFX()
addTheTab()
a = ATry(obj.connect_and_get_trigger())
a.start()
# timer = QTimer()

I'm making a simple browser with a search box in PyQt5. This is what I've written:
import PyQt5

from PyQt5.QtWebKitWidgets import QWebView , QWebPage
from PyQt5.QtWebKit import QWebSettings
from PyQt5.QtNetwork import *
import sys
from optparse import OptionParser
class App(QMainWindow):
def initiate(self):
super().initiate()
self.InitUI()
def initUI(self):
self.setWindowTitle('Browser')
self.setGeometry(100, 200, 1000, 2000)
self.searchbox = QLineEdit(self)
self.searchbox.move(20, 20)
self.searchbox.resize(1500,40)
self.go = QPushButton('Go', self)
self.go.move(1810, 20)
self.go.connect(self.gourl)
self.show()
def gourl(self):
url = self.searchbox.text()
class Browser(QWebView):
def __init__(self):
self.view = QWebView.__init__(self)
self.setWindowTitle('Loading...')
self.titleChanged.connect(self.adjustTitle)
def load(self,url):
self.setUrl(QUrl(url))
App.searchbox.setText(url)
def adjustTitle(self):
self.setWindowTitle(self.title())
app = QApplication(sys.argv)
view = Browser()
box = App()
box.show()
view.show()
view.load("https://duckduckgo.com")
app.exec_()
The browser part loads, but the textbox doesn't show. Python also throws this error:
Traceback (most recent call last):
File "C:\Users\Sid\Desktop\browser.py", line 43, in <module>
view.load("https://duckduckgo.com")
File "C:\Users\Sid\Desktop\browser.py", line 34, in load
App.searchbox.setText(url)
AttributeError: type object 'App' has no attribute 'searchbox'
I don't know why the textbox doesn't show, and I can't understand why the error is being thrown. Can someone please point out the error?
Thanks in advance. :)

This question already has an answer here:
How to fix error in my pyqt programm (first argument of unbound method must have type 'QDialog') ?
(1 answer)
Closed 3 years ago.
I'm trying to build a GUI app using PyQt5 and Python 3.7 and I've decided to break the code in different modules. When i try to import a function that creates an instance of a custom widget, an error related to 'sis'. What I read is that 'sis' is a way of encapsulation C/C++ code to be run in python. But how can I work with that?
This is the code that runs the app:
import sys
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow
class MainWindow(QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.setGeometry(10,35,1500,800)
self.setWindowTitle("Cotizador TuCheff")
#self.setWindowIcon(QtGui.QIcon(''))
mainWindow(self)
def mainWindow(self):
from PyQt5 import QtCore, QtGui, QtWidgets
from Pages.Quote import quote
barMenu = QtWidgets.QTabWidget(self)
tab1 = QtWidgets.QWidget()
quoteLayout = QtWidgets.QVBoxLayout()
quoteGenerator = quote.makeQuoteWindow()
quoteLayout.addWidget(quoteGenerator)
tab1.setLayout(quoteLayout)
barMenu.addTab(tab1, "&Nueva Cotización")
self.setCentralWidget(barMenu)
if __name__ == "__main__":
app = QApplication([])
window = MainWindow()
window.show()
app.exec_()
And file, where I try to get a custom widget, is:
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QApplication
import sys
def makeQuoteWindow():
quoteWindow = QuoteWindow
quoteWindow.create()
#app = QApplication([])
#window = quoteWindow()
#window.show()
#status = app.exec_()
#sys.exit(status)
class QuoteWindow(QtWidgets.QWidget):
def __init__(self):
super(QuoteWindow, self).__init__()
def create(self):
mainWidget = QtWidgets.QWidget()
vLayout1 = QtWidgets.QVBoxLayout()
#=======------------------------ UPPER SIDE -------------------
hLayout1 = QtWidgets.QHBoxLayout()
##A LOT OF WIDGETS AND LAYOUTS
hLayout2 = QtWidgets.QHBoxLayout()
#display content
vLayout1.addLayout(hLayout1)
vLayout1.addLayout(hLayout2)
hLayout2.addItem(vSpacer1)
mainWidget.setLayout(vLayout1)
return mainWidget
if __name__ == "__main__":
makeQuoteWindow()
The error is:
TypeError: create(self, window: sip.voidptr = 0, initializeWindow: bool = True, destroyOldWindow: bool = True): first argument of unbound method must have type 'QWidget'
Try it:
main.py
