[Glade-users] [glade-users] Using a global variable for GladeXML object?

When I create my applications using glade, I create and use the gladeXML

object and return. I do this mainly because I try to avoid global 
variables because that's what I learned somewhere along the way.

I see that a lot of people simply declare the gladeXML object as a 
global variable and use glade_xml_get_widget whenever they need to 
access a widget throughout their code.

I'm curious as to what people's thoughts are on this? Is there a 
"conventional" way? Are there major drawbacks to the latter?

Your original method is sound - carrying a GladeXML object around
is pointless since it consumes a considerable amount of ram (i.e.
an interpreted glade file in data structures + hashmap of widget
names etc)...

Personally I think storing pointers to the widgets you need at
initialization time is best - but there is also another option,
you can write a lookup_widget_by_name() function that recurses
through the hierarchies of all toplevels searching for the widget
by its name (this is a little suboptimal but maybe makes your
code simpler).
