Re: accelerator keys for (right-click) menu only work after menu has been through a show-all

[Dan Hitt <dan hitt gmail com>]

So Martin Horauer pointed out the solution to me, in private mail ----
thanks Martin!!

I'm recounting his solution here in case somebody else hits this
problem and is searching the net for something and gets to this
thread.

He gave me a link to a site
http://zetcode.com/gui/gtk2/menusandtoolbars/
which has an example popupmenu.c.

There are no accelerator keys in popupmenu.c, but as he says, the
example above them has them, so you can just paste in the code.

And it works without doing the right click even an initial time, the
solution being that you have to do a 'show' on the menu item after
creation (which probably deep in the bowels of gtk does something).

And this also worked for me in my little app (written in the d
programming language, using gtkd which is wraps up gtk3 for d).
