There is a Treeview with several TreeViewColumns. Because the default font-size is to big for my usage, I need to set the font-size in the TreeViewColumn Header.
I tried to following:
tvc = Gtk.TreeViewColumn()
tvcl = Gtk.Label("Test")
tvc.set_widget(tvcl)
But the Header of the Column is empty then. If it's possible to change the font of the TreeViewColumn().title, this would be enaugh.
Assuming you're using python (from the code), here's an example:
from gi.repository import Gtk
from gi.repository import Pango
tvc = Gtk.TreeViewColumn (None, renderer, col)
custom_header = Gtk.Label ('Test')
tvc.set_widget (custom_header)
tvc.get_widget ().override_font (Pango.FontDescription.from_string ('8') )
tvc.get_widget ().show_all ()
