gtk_entry

[Ed Schreder <eds kendeco com>]

 I'm just learning gtk and need some help. I need to pass the contents of 
three entry boxes to a button signal callback. How would I do this?
Is there a way to access a widget which is on another widget which is 
on yet another widget?  such as WindowWidget->hbox->entry to access the 
entry widget on the hbox on the window? or is this a stupid thing to wanna
do?
