Q: 'Multithread' aplications

[Eduardo Perez <eduperez redestb es>]

How can I show (and make 'active') a window before returning to gtk.

Secuence must be something like:
	user clicks a function
	a signal is raised
	signal function starts
		signal function shows another window
		user can interact with new window
		signal function continues execution
		signal function updates new window
		user can interact with updated new window
	signal function ends

My problem is how can I make second window active before signal function
returns; and how to continue exeution after showing new window without
stopping signal function.

Many thanks.
