Highlight specific substrings in a QTreeView

问题

I want to highlight (or in general customise the formatting) of specific substrings appearing in a QTreeView in PyQt. To demonstrate what I mean, I have taken the example at PyQt4\examples\itemviews\dirview.pyw and manually added highlighting:

Here all instances of the substring 'as' are highlighted, but in general it might not be a pattern match, I may actually want to be very specific.

I know that this can be easily done to a QTextEdit as per this SO question, but that relied on moving around the textCursor which I don't believe exists for a QTreeView.

Can this be easily done?
