[Sugar-devel] XML markup capability for a gtk.Button label (PyGTK)?

[Art Hunkins]

Thanks for the code suggestion, Tomeu.

The entire method (into which your suggestion was inserted, and which 
otherwise is from Victor's csndsugui) was this:

    def cbbutton(self,box,callback,title=""):
       """Creates a callbackbutton
          box: parent box
          callback: click callback
          title: if given, the button name
          returns the widget instance"""
       self.cbbutts = self.cbbutts + 1
       label = gtk.Label()
       label.set_markup(title)
       butt = gtk.Button()
       butt.child = label
       label.show()
       box.pack_start(butt, False, False, 5)
       self.cbbuttons.append([butt,label,0])
       butt.connect("clicked", callback)
       butt.show()
       return butt

Unfortunately, the above code fails with this Log (I probably confounded 
something in this larger setting):

/usr/lib/python2.6/site-packages/sugar/util.py:25: DeprecationWarning: the 
sha module is deprecated; use the hashlib module instead

import sha

activity.show()

**

Gtk:ERROR:gtkwidget.c:7967:gtk_widget_real_map: assertion failed: 
(GTK_WIDGET_REALIZED (widget))



I have tried positioning the two .show() lines at different points to no 
avail.

Do you (or anyone else) have further ideas?

Can you try with this?

label = gtk.Label()
label.set_markup(title)
butt = gtk.Button()
butt.child = label
label.show()

Thanks,
