Hello,
If anyone has an idea on how to resolve the buggy delegate behavior I
mention below, I'd great appreciate it!
Thanks!

Hello,
Looking at documentation for the QSqlRelationalDelegate class, I've
hacked my way through to displaying a pixmap in a table view, though
it's buggy.
Hopefully, someone will be able to suggest solutions or
documentation/examples to fix the following:
- at launch, the fields display the path strings to the images,
instead of the images themselves
- on double-clicking, the fields suddenly display the images (hurray!)
- on making any other mouse-click selections in the table, all data
(image, text string, &c.) vanish (???)
My ThumbnailDelegate class follows below.
Thanks in advance!
Scott
class ThumbnailDelegate(QtSql.QSqlRelationalDelegate):
def __init__(self, parent=None):
super(ThumbnailDelegate, self).__init__(parent)
def paint(self, painter, option, index):
QtSql.QSqlRelationalDelegate.paint(self, painter, option, index)
def createEditor(self, parent, option, index):
if index.column() == THUMBNAIL:
editor = QtGui.QLabel(parent)
return editor
else:
return QtSql.QSqlRelationalDelegate.createEditor(self,
parent,
option, index)
def setEditorData(self, editor, index):
if index.column() == THUMBNAIL:
imageStr = index.model().data(index,
QtCore.Qt.DisplayRole).toString()
imageMap =
QtGui.QPixmap(QtCore.QString(self.tr(imageStr)))
editor.setPixmap(imageMap)
else:
QtSql.QSqlRelationalDelegate.setEditorData(self,
editor, index)
def setModelData(self, editor, model, index):
if index.column() == THUMBNAIL:
model.setData(index, QtCore.QVariant(editor.text()))
else:
QtSql.QSqlRelationalDelegate.setModelData(self, editor,
model,
index)

Can anyone point me to documentation &/or examples for setting
pixmaps in a table view that gets its data from a table model?
I have a table view I populate from a QSqlRelationalTableModel
instance. One of the model's data fields is an absolute path to
small thumbnail images on disk. I'd like to intercept the model's
data for the image paths and paint the images as pixmaps in one of
the columns of cells of the table view.
Thanks in advance!
