Re: Help with gtktext.c/find_line_containing_point() function

[Mikael Hermansson <mikeh bahnhof se>]

GtkExText is NOT a subclass of GtkText. GtkExText parent is GtkEditable. 
This means the specified bug will not appear in GtkExText :-)

The only reason API looks like GtkText is to make it simple convert from
GtkText -> GtkExText.

Greats
