How to add my UI in new tab to qtabwidget?

[aadil50]

import sys
from PyQt5 import QtCore, QtGui, QtWidgets,uic

class TestGUI(QtWidgets.QMainWindow):
    def __init__(self):
        super(TestGUI, self).__init__()
        self.myui =  uic.loadUi('SPTMain.ui', self)
        self.NewTab.clicked.connect(self.handleAddTab)

    def handleAddTab(self):
        contents = QtWidgets.QWidget(self.myui)
        layout = QtWidgets.QVBoxLayout(contents)
        self.tabWidget.addTab(contents, 'Tab One')

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = TestGUI()
    window.show()
    sys.exit(app.exec_())

Actually It adds blank tab... Kindly guide me how can I add new tab as my ui (duplicate of my .ui file in new tab)

contents = QtWidgets.QWidget(self.myui)

What is this supposed to do? It creates a new, empty QWidget with self.myui as its parent, hence a "blank tab".

I don't understand the architecture of your application. It has a QMainWindow, which is what you show(). Meanwhile that main window creates some self.myui with SPTMain.ui loaded into itself. Yet at the same time you want it loaded into some other widget to use for tab within the main window.

So how can I improve it to achieve my task.. As you know i have shown what I want to do and what i have done.. Thanks...

Maybe someone else understands what your SPTMain.ui is, whether it is the content for the main window or for some widget you want to add as a tab to somewhere, or what, and what your variable named self.myui is for --- but I don't. So hopefully someone else will answer you.

[Maybe you should have no contents = QtWidgets.QWidget(self.myui), self.myui should be renamed self.tab1 and just self.tabWidget.addTab(self.tab1, 'Tab One'). I don't know.]

self.myui

It is my ui which contain multliple Widgets.. I just want to show it in my tab.. By inheriting my class of ui and adding to addtab funtion hangs and windows disappear.. So I have done all my tries what i can and know.. But still cannot get idea how can i show my ui in new tab aka duplicate my ui in new tab...

• contents = QtWidgets.QWidget(self.myui) You do not want this, I explained what it does earlier.
• self.myui should be renamed self.tab1 The .ui file seems to describe the content of a tab, so it's a name which means something.
• self.tabWidget.addTab(self.tab1, 'Tab One') Intended to add self.tab1 as a tab.

I'm a little confused by two different patterns I see for uic.loadUi(), which is a PyQt-only thing. Try this:

# in `__init__()`
self.tab1 = uic.loadUi('SPTMain.ui')

# in `handleAddTab()`
self.tabWidget.addTab(self.tab1, 'Tab One')

It crash the window app...

The following works for me. I had to hack together a couple of things (including changing from main window to a generic widget) since I do not have (nor want!) whatever you have.

import sys
from PyQt5 import QtCore, QtGui, QtWidgets,uic

class TestGUI(QtWidgets.QWidget):
    def __init__(self):
        super(TestGUI, self).__init__()
        layout = QtWidgets.QVBoxLayout(self)
        self.NewTab = QtWidgets.QPushButton("Create Tab", self)
        layout.addWidget(self.NewTab)
        self.tabWidget = QtWidgets.QTabWidget(self)
        layout.addWidget(self.tabWidget)
        self.tab1 =  uic.loadUi('/path/to/somefile.ui')
        self.NewTab.clicked.connect(self.handleAddTab)

    def handleAddTab(self):
        self.tabWidget.addTab(self.tab1, 'Tab One')

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = TestGUI()
    window.show()
    sys.exit(app.exec_())
