best way to use multiple windows

[Thiago Guzella <thiago guzella gmail com>]

Greetings everyone,


I am writing a simple GTKmm (btw, GTKmm 2.4) application, which has a
main window, a menu, etc, using glade (just to place the widgets).
Some options in the menu (such as "preferences") are required to open
a modal window, with apply and revert buttons, allowing the user to
tweak the app; pretty straightforward :)

My question is: what is the best way to implement such feature? should
i make the "preferences" window a member variable of the main window
class, create it (i.e.: alloc memory) when it is requested?? if so,
how should i handle the window closing? my first guess would be to
send a signal to the main window to hide the preferences window and
release the memory used by it, so that the main window will regain
focus.
