More compact layout

Question

In the following code, I'd like to get rid of the margin around the buttons. I'd like to have the buttons stretch all the way to the edge of the frame. How can I do that?

import sys

from PyQt4.QtGui import *
from PyQt4.QtCore import *

app = QApplication(sys.argv)
window = QWidget()
layout = QVBoxLayout()
layout.setSpacing(0)
window.setLayout(layout)
for i in range(2):
    layout.addWidget(QPushButton())
window.show()
app.exec_()

Answer 1

layout.setContentsMargin(0, 0, 0, 0)

should do the trick

Answer 2

Unfortunately I don't have a working Qt at hand to try right now, but I believe you might get your wish by using style sheets with both margins and padding set to 0 (you might also need to tweak the size policy, as it might otherwise block the widgets from some kind of stretching your style requires).
