[PyQt] table model and pixmap

[Scott Frankel]

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)
