You get a gold star! This works.
I put the method -
def label_size_allocate_hack(widget, allocation):
"Callback which re-allocates the size of a label."
layout = widget.get_layout()
lw_old, lh_old = layout.get_size()
# fixed width labels
if lw_old / pango.SCALE == allocation.width:
return
# set wrap width to the pango.Layout of the labels
layout.set_width(allocation.width * pango.SCALE)
lw, lh = layout.get_size() # lw is unused.
if lh_old != lh:
widget.set_size_request(-1, lh / pango.SCALE)
- in my hacks.py file, and then -
from hacks import label_size_allocate_hack
...
label = gtk.Label()
label.set_markup('<tt>{0}</tt>'.format(glib.markup_escape_text(annotation['comment'])))
label.set_alignment(0.0, 0.0)
label.set_line_wrap(True)
label.set_selectable(True)
label.connect_after("size-allocate", label_size_allocate_hack)
vbox.pack_end(label, expand=True, fill=True, padding=2)
- and the labels seem to be behave more sanely, at least horizontally.
Now they are jumping up and down vertically within the vbox when the
window is resized. Hmm.
