Setting QWidget size

[Rodrigo de Salvo Braz]

Hi Rich,

It seems your object 'bio' is not being used after creation so it won't
have an effect.

I've changed your code to subclass from QMainWindow, and added a statement
self.setCentralWidget(container), and it now seem to be doing what you
want. Please let me know if that's not true.

Rodrigo

#!/usr/bin/env python3

import sys

from PyQt5 import QtWidgets as qtw
from PyQt5 import QtGui as qtg
from PyQt5 import QtCore as qtc
from PyQt5.QtWidgets import QMainWindow


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

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

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

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

        self.setCentralWidget(container)

        self.show()

    # Methods
    def save(self):
        pass

    def cancel(self):
        pass


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