Pygtk3指定gtk3标签/ CellRenderer字体

Question

According to a pygtk2 doc on faq.pygtk.org The way to change a font is by a definition like so:

...

label = gtk.Label("MyLabel")
label.modify_font(pango.FontDescription("sans 48"))
...

What is the equivalent in pyGtk3?

I was looking to avoid the use of a gtk css definition. Though I would happily accept an answer that utilizes gtk's css support.

My target font is gnu unifont ( unifont medium ), in case that changes anything; This font is readily available in tty format.

I've assumed at this point that applying a font to a label is similar to applying a font to a table cell, though an example of both would be ideal.

The latest pygtk3 docs don't appear to cover this topic whatsoever: http://python-gtk-3-tutorial.readthedocs.org/en/latest/label.html , and font is hardly mentioned accross the entirety of the documentation.

Answer 1

It's basically the same:

from gi.repository import Gtk, Pango
label = Gtk.Label('MyLabel')
label.modify_font(Pango.FontDescription('Dejavu Sans Mono'))

Answer 2

One approach is to use Pango markup [1]:

label = Gtk.Label()
label.set_markup("<span font_desc='unifont medium'>%s</span>" % 'some text')
