Question

I want to have a left justified label with some bold text in it, but using the following code (which returns no error) the justification isn’t set… Has anyone a clue ? (python2.7, gtk2.24)

label=gtk.Label("<b>"+text+"</b>")
label.set_use_markup(True)
label.set_justify(gtk.JUSTIFY_LEFT)

Thanks in advance !

Answer 1

The PyGTK documentation of gtk.Label.set_justify() says:

If you want to set the alignment of the label as a whole, use the gtk.Misc.set_alignment() method instead. The set_justify() has no effect on labels containing only a single line.

Following the link to the gtk.Misc.set_alignment() documentation shows how to correctly do what you’re asking (if I interpreted your question correctly):

import gtk

w = gtk.Window()
w.connect('destroy', gtk.main_quit)
text = 'whatever'
label=gtk.Label("<b>"+text+"</b>")
label.set_use_markup(True)
label.set_alignment(0, 0.5)
w.add(label)

w.show_all()

gtk.main()
