setColumnWidth() doesn't work for QTableView

[rulfzid]

I'm finding I can't programmatically resize a column in a QTableView with setColumnCount(). 

The function does seem to work with QTreeViews though, which is weird.

I've found a workaround, using tableview.horizontalHeader().resizeSection(col, pixels), but just wondering if this a bug somewhere.

Simple code to see the behavior:

********************

#!/usr/bin/python

from PySide.QtCore import *

from PySide.QtGui import *

import sys

app = QApplication(sys.argv)

model = QStandardItemModel()

model.setHeaderData(0, Qt.Horizontal, "Date")

model.setHeaderData(1, Qt.Horizontal, "Time")

model.setHeaderData(2, Qt.Horizontal, "Proc")

model.setItem(0, 0, QStandardItem("First"))

model.setItem(0, 1, QStandardItem("Second"))

model.setItem(0, 2, QStandardItem("Third"))

table = QTableView()

table.setModel(model)

# table.setColumnWidth(0, 150) # <--- this doesn't work!

table.horizontalHeader().resizeSection(0, 150)

vbox = QVBoxLayout()

vbox.addWidget(table)

dialog = QDialog()

dialog.setLayout(vbox)

dialog.resize(400, 400)

dialog.show()

sys.exit(app.exec_())

Hello!

I tried your code and with my OS (Ubuntu 10.10), it works great, both ways give the same result!
Instead you can also try the .resizeColumnsToContents() functions. This is a nice way to adjust the column width to the needed width.

Have a nice day!

That's weird, because I'm on Ubuntu 10.10 as well. Glad it's working for you, though. :)
