gtk_statusbar!

[ferri_marllo gva es]

Hi everyone!

I built a gtk_application with glade,it's a main window with menu.When i select
a menu option, my program opens a new window with entries and buttons.
In  the entry i write the name of a file to open.

This file has the structure:

number1   (ex.25)
number 2   (ex.34)
operation   (product)

after writing the name,i push the button and it's called the function
real_opration()
This function mekes a lot of things,but the first one is read the numbers of
entry_file and the opration.
i'd like that in the status bar of this window(not main_window),it'll be
written...

reading number 1...
reading number 2...
operating..........
End

i tried but only is written End.
How can i change the content of statusbar,during reading the entry_file??

thanks a lot
