[pygtk] set_use_markup and gtk.SpinButton

[Art Hunkins]

Sorry, Nathan - I get no joy from:
spin.get_layout().set_font_description(pango.FontDescription('normal 10'))
or any variants I've tried.

Either I get something that runs with no errors, but displays the same old size; or I get a Log that specifies further syntax/logical errors I can't fathom (different for each variant I try).

I appreciate your help nonetheless.

  Since it seems you need to pass a pango.FontDescription you could try:

  spin.get_layout().set_font_description(pango.FontDescription('normal 10'))

  Although I never used get_layout and/or set_font_description and/or pango (directly)

    I am trying to use a variant of your first suggestion:
    spin.get_layout().set_font_description('normal 10')

    ('normal 10' is even one of the examples in the reference manual). All I
    want to do is to set the size larger.

    However, I get this error message:
    TypeError: desc should be a PangoFontDescription or None.

    "None" works, but I haven't been able to get anything else to do so,
    including ('Sans 10 Bold').

    Any ideas?
