[gtkmm] Gtk::Entry right alignment

[Akbar <linux cwazy co uk>]

I am making a simple calculator using gtkmm library. I use Gtk::entry
for the display. The problem is all calculator display the value with
right alignment. But my calculator display the value from left to right.
Is there anyway I can make it right alignment? After googling, I found
this link.

They said I cann't do it. But it is in 2001. Maybe there is improvement
for this 2-3 years.......
