Hi, all

I want to use some GtkCheckButton to display some status in my app.But I want to forbid my customer to change 
these checkbuttons' status(choosed or not ) by their hands,and they can only be changed by my app itself 
according to  some values,etc..I want to know how to do this.Will some one help me?Thank you.

And I do not know if I choosed the right widget to do this task.If not, will some one tell me which one 
should be better? Thank you again.
