[PyQt] setItemDelegateForColumn() doesn't work? (so setItemDelegateForRow() does)

[Zhaohao Liang]

Hi

I'm using PyQt 4.6.2 for Python 2.6. It seems that the
setItemDelegateForColumn() of QTableWidget doesn't work.
I have checked it with below code:

    print ui.tableWidget.itemDelegateForColumn(0)
    ui.tableWidget.setItemDelegateForColumn(0, MyItemDelegate())
    print ui.tableWidget.itemDelegateForColumn(0)

It will print two "None" as result.

ps: This will happen for setItemDelegateForRow()

Please help to check it. Thank you!

#Here is the sample code:

import sys
from PyQt4 import QtCore, QtGui

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)
        self.tableWidget = QtGui.QTableWidget(Dialog)
        self.tableWidget.setGeometry(QtCore.QRect(60, 40, 256, 192))
        self.tableWidget.setObjectName("tableWidget")
        self.tableWidget.setColumnCount(2)
        self.tableWidget.setRowCount(1)
        item = QtGui.QTableWidgetItem()
        self.tableWidget.setVerticalHeaderItem(0, item)
        item = QtGui.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(0, item)
        item = QtGui.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(1, item)

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        Dialog.setWindowTitle(QtGui.QApplication.translate("Dialog",
"Dialog", None, QtGui.QApplication.UnicodeUTF8))
        self.tableWidget.verticalHeaderItem(0).setText(QtGui.QApplication.translate("Dialog",
"row0", None, QtGui.QApplication.UnicodeUTF8))
        self.tableWidget.horizontalHeaderItem(0).setText(QtGui.QApplication.translate("Dialog",
"column0", None, QtGui.QApplication.UnicodeUTF8))
        self.tableWidget.horizontalHeaderItem(1).setText(QtGui.QApplication.translate("Dialog",
"column1", None, QtGui.QApplication.UnicodeUTF8))

class MyItemDelegate(QtGui.QItemDelegate):
    def __init__(self, parent = None):
        QtGui.QItemDelegate.__init__(self, parent)

    def setEditorData(self, editor, index):
        print editor
        print index

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    window = QtGui.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(window)
    print ui.tableWidget.columnCount()
    print ui.tableWidget.itemDelegateForColumn(0)
    ui.tableWidget.setItemDelegateForColumn(0, MyItemDelegate())
    print ui.tableWidget.itemDelegateForColumn(0)

    print ui.tableWidget.rowCount()
    print ui.tableWidget.itemDelegateForRow(0)
    ui.tableWidget.setItemDelegateForRow(0, MyItemDelegate())
    print ui.tableWidget.itemDelegateForRow(0)

    window.show()
    sys.exit(app.exec_())
