Expanding label characters

Question

Consider the following toy example:

from PyQt5 import QtWidgets, QtGui

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        self.w = QtWidgets.QWidget()
        layout = QtWidgets.QVBoxLayout()
        self.w.setLayout(layout)
        self.setCentralWidget(self.w)

        toyLabel = QtWidgets.QLabel("Hello!")
        layout.addWidget(toyLabel)

        font = QtGui.QFont("Times", 16, QtGui.QFont.Bold)
        font.setStretch(150)
        toyLabel.setFont(font)

if __name__ == '__main__':
    app = QtWidgets.QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()

How can I expand the letters of toyLabel without distorting it?

When using setStretch() as above the result is a mess:

I have also tried to expand the letters using a font-stretch property in a stylesheet but this is not supported.

Answer 1

Apparently, this can be set directly in the font stylesheet property:

QLabel {
    font: 12px Times Expanded;
}
