Changing the selected item colour in a GtkTreeview using python

Not sure what you mean by flickering. A border would require subclassing TreeView.

I'd make the STATE_SELECTED color identical to STATE_NORMAL to disable the built-in highlighting. Then set a data_func on each column and change some color on the cell renderer depending on whether it's in the selection or not.

You're probably already doing this for your priority, so just multiply the color with something to highlight a row.
