	Excuse me, in my last e-mail I didn't tell it right.

	I define a button (a MEDIA_PLAY from Gtk stock) using glade. I
"import" it in my code using the Xfc::Glade xml object as you tell in
your tutorials and it works fine. Hence, I do not explicitly use the
constructors.

	The problem appears when I want to change the button image from
MEDIA_PLAY to MEDIA_PAUSE. I use the set_image() method, but as you
tell in the tutorial it is mandatory to previously define the label for
the button. I cannot change button image without defining the label,
which I define as "". If I do not define this label, button image do
not change.

	What is the way to change a button image with no label defined?

	I tried to compile the code with my own makefile (I didn't use
the autoconf generated makefile) and I used the -static flag. I
searched for the static version of libGlade but I didn't find it. I
will try with this option.

	Thanks, it worked! But finally I think I will not use this
feature, because too long text may resize window to 'stupid' big
sizes .

	Feelings and intuition is sometimes wrong ... ;-)


	Thanks!
