hi,
the example is the one described here:
http://doc.qt.nokia.com/4.5/itemviews-coloreditorfactory.html
not sure, but i think PyQt >= 4.4 and Qt >= 4.2 are needed for this to
work properly.
from PyQt4 import QtCore, QtGui

QtGui.QComboBox.__init__(self, parent)
self.populateList()

self.setCurrentIndex(self.findData(QtCore.QVariant(color),
QtCore.Qt.DecorationRole))
color = QtCore.pyqtProperty('QColor', getColor, setColor, user=True)

for i, name in enumerate(QtGui.QColor.colorNames()):
self.insertItem(i, name)
self.setItemData(i, QtCore.QVariant(QtGui.QColor(name)),
QtCore.Qt.DecorationRole)
class ColorListCreator(QtGui.QItemEditorCreatorBase):
def __init__(self):
QtGui.QItemEditorCreatorBase.__init__(self)
def createWidget(self, parent):
return ColorListEditor(parent)
class Window(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
factory = QtGui.QItemEditorFactory()
colorListCreator = ColorListCreator()
factory.registerEditor(QtCore.QVariant.Color, colorListCreator)
QtGui.QItemEditorFactory.setDefaultFactory(factory)
self.createGUI()
def createGUI(self):
data = ((self.tr('Alice'), QtGui.QColor('aliceblue')),
(self.tr('Neptun'), QtGui.QColor('aquamarine')),
(self.tr('Ferdinand'), QtGui.QColor('springgreen')))
table = QtGui.QTableWidget(3, 2)
table.setHorizontalHeaderLabels(QtCore.QStringList()
<< self.tr('Name')
<< self.tr('Hair Color'))
table.verticalHeader().setVisible(False)
table.resize(150, 50)
for i, (name, color) in enumerate(data):
nameItem = QtGui.QTableWidgetItem(name)
colorItem = QtGui.QTableWidgetItem()
colorItem.setData(QtCore.Qt.DisplayRole,
QtCore.QVariant(color))
table.setItem(i, 0, nameItem)
table.setItem(i, 1, colorItem)
table.resizeColumnToContents(0)
table.horizontalHeader().setStretchLastSection(True)
layout = QtGui.QGridLayout()
layout.addWidget(table, 0, 0)
self.setLayout(layout)
self.setWindowTitle(self.tr('Color Editor Factory'))
