How can I enter variables in Glade:
For instance in the file send with this message I do want the part 
"imagemenuitem1" not to have a constant string but a variable which I 
derive from a array (GB .. ESP) of unbounded_string element named 
Lan__New (Lan) where Lan id of the type (GB .. ESP).
The purpose is that I can change the language from with in my program.
Glade is a fine program to design a GUI but I cannot find how to enter 
such a variable which inside the .glade file should be in the line:
<property name="label" 
translatable="yes">To_String(Lan_New(Lan))</property> But when I do it 
that way I get the string:
To_String(Lan_New(Lan)) in the menu instead of New when I select 
GB("English").
I also do not want if there is a way outside of Glade to use that way 
everytime I change somthing in the GUI to carry out the changes i want 
over again
