How do you set the column width on a QTreeView?

Bear with me, I'm still new to QT and am having trouble wrapping my brain around how it does things.
I've created and populated a QTreeView with two columns:
class AppForm(QMainWindow):
def __init__(self, parent = None):
super(AppForm, self).__init__(parent)
self.model = QStandardItemModel()
self.view = QTreeView()
self.view.setColumnWidth(0, 800)
self.view.setEditTriggers(QAbstractItemView.NoEditTriggers)
self.view.setModel(self.model)
self.setCentralWidget(self.view)
Everything's working great, except the columns are extremely narrow. I hoped that setColumnWidth(0, 800) would widen the first column, but it doesn't seem to be having any effect. What's the proper method for setting column widths?

When you call setColumnWidth, Qt will do the equivalent of:
self.view.header().resizeSection(column, width)
Then, when you call setModel, Qt will (amongst other things) do the equivalent of:
self.view.header().setModel(model)
So the column width does get set - just not on the model the tree view ends up with.
tl;dr: set the column width after you set the model.
EDIT
Here's a simple demo script based on your example:
from PyQt4 import QtGui, QtCore
class Window(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.model = QtGui.QStandardItemModel()
self.view = QtGui.QTreeView()
self.view.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)
self.view.setModel(self.model)
self.setCentralWidget(self.view)
parent = self.model.invisibleRootItem()
for item in 'One Two Three Four'.split():
parent.appendRow([
QtGui.QStandardItem(item),
QtGui.QStandardItem(),
QtGui.QStandardItem(),
])
self.view.setColumnWidth(0, 800)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec_())

I moved setColumnWidth below setModel, but it still doesn't seem to be having an effect. Is the problem that I haven't populated it or set the amount of columns yet?

Awesome -- I moved setColumnWidth into a different function so that it's called after it populates the tree. Everything's working as expected now. Thanks for your help!

self.view.resizeColumnToContents(0)
This makes sure that given column's width and height are set to match with content.
