Setting QWidget size

[Rodrigo de Salvo Braz]

Rich,

Yes, just like we built one container for a single tab, we could have built
multiple containers, each with its own layout and widgets, and added them
all to QTabWidget.

BTW, even the title bar and frame can be removed from a QMainWindow if you
use a window flag Qt.FramelessWindowHint, as shown below (I had to remove
qwt because it was somehow interfering with the package for that):

#!/usr/bin/env python3

import sys

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QMainWindow, QWidget, QGridLayout, QPushButton,
QTabWidget, QApplication


class TestWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        bio = QWidget(windowTitle='Test', width = 800, height = 600)

        # Layout
        container = QWidget(self)
        group1 = QGridLayout()
        container.setLayout(group1)

        savebutton = QPushButton('Save')
        savebutton.clicked.connect(self.save)
        group1.addWidget(savebutton, 0, 0)

        cancelbutton = QPushButton('Cancel')
        cancelbutton.clicked.connect(self.cancel)
        group1.addWidget(cancelbutton, 0, 1)

        tabwidget = QTabWidget(self)
        tabwidget.addTab(container, "My tab")

        self.setCentralWidget(tabwidget)

        self.setWindowFlags(Qt.FramelessWindowHint)

        self.show()

    # Methods
    def save(self):
        pass

    def cancel(self):
        pass


if __name__ == '__main__':
    app = QApplication(sys.argv)
    bio = TestWindow()
    sys.exit(app.exec())
