    <p>I want my QTableView to have a column of comboBoxes. After a lot of try-outs, I've reached my goal : display the comboBoxes.</p> <p>Now my problem is that they won't keep the selected item displayed.</p> <p>I use a custom delegate to do it, below is the relevant code : </p> <p>class ComboBoxDelegate(QtGui.QItemDelegate):</p> <pre><code>def __init__(self, owner, itemslist): QtGui.QItemDelegate.__init__(self, owner) self.itemslist = itemslist def paint(self, painter, option, index): # Get Item Data value = index.data(QtCore.Qt.DisplayRole).toInt()[0] # fill style options with item data style = QtGui.QApplication.style() opt = QtGui.QStyleOptionComboBox() opt.currentText = str(self.itemslist[value]) opt.rect = option.rect # draw item data as ComboBox style.drawComplexControl(QtGui.QStyle.CC_ComboBox, opt, painter) def createEditor(self, parent, option, index): # create the ProgressBar as our editor. editor = QtGui.QComboBox(parent) editor.addItems(self.itemslist) editor.setCurrentIndex(0) editor.installEventFilter(self) return editor def setEditorData(self, editor, index): value = index.data(QtCore.Qt.DisplayRole).toInt()[0] editor.setCurrentIndex(value) def setModelData(self,editor,model,index): value = editor.currentIndex() model.setData(index, QtCore.QVariant(value)) def updateEditorGeometry(self, editor, option, index): editor.setGeometry(option.rect) class SequenceGridModel(QtCore.QAbstractTableModel): def __init__(self, datain, headerdata, parent=None, *args): QtCore.QAbstractTableModel.__init__(self, parent, *args) self.parent = parent self.arraydata = datain self.headerdata = headerdata def flags(self, index): if index.column() == 13: return QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | QtCore.Qt.ItemIsEditable return QtCore.QAbstractTableModel.flags(self, index) def data(self, index, role = QtCore.Qt.DisplayRole): if not index.isValid(): if role == QtCore.Qt.UserRole: return None else: return QtCore.QVariant() value = QtCore.QVariant(self.arraydata[index.row()][index.column()]) if QtCore.Qt.UserRole == role: return value elif role == QtCore.Qt.DisplayRole or role == QtCore.Qt.EditRole: return QtCore.QVariant(value) return QtCore.QVariant() class SequenceGrid(QtGui.QTableView): def __init__(self, parent=None): QtGui.QTableView.__init__(self, parent) self.selectedIndexes = [] self.parent = parent self.checkValues = ['TODO', 'WAITING', 'RETAKE', 'OK'] self.model = SequenceGridModel(self.data, header, self) self.setModel(self.model) self.setEditTriggers(QtGui.QAbstractItemView.CurrentChanged) self.viewport().installEventFilter(self) self.setItemDelegateForColumn(13,ComboBoxDelegate(self, self.checkValues)) self.setColumnWidth(13, 64) </code></pre> <p>Thanks for your attention !</p>

    2. COThat's right, I thought it would use the default one. I found a solution to my problem however. I called the QAbstractItemView.openPersistentEditor(index) function from the paint() method and it seem to work.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
