GNOME Druids
GNOME Druid is a set of widgets that provide a consistent way to walk
users through several stages of an initial configuration process. It
fulfills the role "Wizards" play in the windows world.
The main widget in the Druid is the GnomeDruid widget. It is a
container widget that holds the information pages inside. It handles
all of the control flow during the setup. It will go through all the
pages in it in a linear fashion by default, and keeps track of which
page is currently shown. Every page in it is inherits from the
GnomeDruidPage virtual widget.
There are actually three different GnomeDruidPage widgets
currently available. They are the GnomeDruidPageStart, the GnomeDruidPageStandard, and the GnomeDruidPageFinish. These widgets are,
quite obviously the beginning, middle and end pages of a druid. The
first and last are quite similar in look, and let you set a large number
of properties, such as color, title, text, and watermark and logo
images. The Standard page is a little less defined, has a
GtkVBox that you can pack your own widgets into. While these
widgets are sufficient for most tasks, if you do need a custom widget,
you can inherit from GnomeDruidPage.
Every time the user changes pages, the current page will send out a
"next" or "back" signal to let the application know. It can select
which page to show next based on how you handle the signal. In
addition, the page can change the sensitivity of the "Next" and "Back"
buttons to restrict the user from progressing until enough information
has been entered.
