Catalin George Festila: Python Qt5 - QTabWidget example.

Today I test the QTabWidget with an simple example.
The source code uses the QTabWidget and create two Tab: FirstTab and TabTwo.
I add for each tab two labels: tab_one_label_one, tab_one_label_two,tab_two_label_one and tab_two_label_two.
For layouts, I used: vboxLayout with first_layout and second_layout.
The result of my running code is this:

The rest of the source code is simple:

import sys
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import QDialog, QApplication, QWidget
from PyQt5.QtWidgets import QVBoxLayout, QTabWidget, QLabel

class TabDialog(QDialog):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Tab Widget Application")
        self.setWindowIcon(QIcon("icon.png"))

        tabwidget = QTabWidget()
        tabwidget.addTab(FirstTab(), "First Tab")
        tabwidget.addTab(TabTwo(), "Second Tab")

        vboxLayout = QVBoxLayout()
        vboxLayout.addWidget(tabwidget)

        self.setLayout(vboxLayout)

class FirstTab(QWidget):
    def __init__(self):
        super().__init__()
        tab_one_label_one = QLabel("tab_one_label_one")
        tab_one_label_two = QLabel("tab_one_label_two")

        first_layout = QVBoxLayout()
        first_layout.addWidget(tab_one_label_one)
        first_layout.addWidget(tab_one_label_two)
        self.setLayout(first_layout)

class TabTwo(QWidget):
    def __init__(self):
        super().__init__()
        tab_two_label_one = QLabel("tab_two_label_one")
        tab_two_label_two = QLabel("tab_two_label_two")

        second_layout = QVBoxLayout()
        second_layout.addWidget(tab_two_label_one)
        second_layout.addWidget(tab_two_label_two)
        self.setLayout(second_layout)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    tabdialog = TabDialog()
    tabdialog.show()
    app.exec()
