Description Sébastien Wilmet 2013-12-24 13:08:08 UTC 
GtkSourceView has a hacky implementation for highlighting the current line. And with the port of GtkTextView to the pixel cache, there were some problems.

The paragraph-background GtkTextTag property can not be used to highlight an empty line at the end of the buffer, and this can not be easily changed (see bug #313718).

So it would be nice to have an API in GtkTextView to have a clean implementation for the current line highlighting.

Note that drawing a line background color is also used by GtkSourceMark, see the GtkSourceMarkAttributes:background property.
Comment 2 Matthias Clasen 2014-01-05 17:01:21 UTC 
would be great to see an api proposal and patch for this
Comment 3 Sébastien Wilmet 2014-07-31 14:19:21 UTC 
No longer needed, there is now the GtkTextView::draw_layer virtual function.
