I have tried calling self.setStyleSheet("background: transparent; border: transparent;") on a QGraphicsView, but it still leaves a 1 pixel border on the top edge. I have also tried replacing border: transparent; with border-style: none;, but it didn't work either.

Here is a screenshot of the problem:

What command will fully remove the border from the QGraphicsView?

You can use one of the following css rule:

graphicsView.setStyleSheet("border-width: 0px; border-style: solid")

or

graphicsView.setStyleSheet("border: 0px")

Your border should disappear.

import sys
from PyQt4.QtGui import *class Ui(QWidget):def __init__(self, parent=None):QWidget.__init__(self, parent)graphicsView = QGraphicsView()graphicsView.setStyleSheet("border: 0px")grid = QGridLayout()grid.addWidget(graphicsView)self.setLayout(grid)app = QApplication(sys.argv)
ui = Ui()
ui.show()
sys.exit(app.exec_())

Here is the widget with the default style:

And now the widget with the style applied:
