<span class="STRUCTNAME">GnomeDEntryEdit</span> is a
very specialized object; it is a sort of "widget
manager" that creates and keeps track of two child
widgets, an "easy" and an "advanced" page. The two
pages combine to let the user edit a Gnome .desktop
entry, as described in <a href="z72.html#SEC-.DESKTOP">
the section called <i><tt class="APPLICATION">
.desktop</tt> Entries</i> in the chapter called <i>
Creating Your Source Tree</i></a>. <span class=
"STRUCTNAME">GnomeDEntryEdit</span> is intended to be
used in conjunction with a preexisting <tt class=
"CLASSNAME">GtkNotebook</tt>. It isn't a <tt class=
"CLASSNAME">GtkNotebook</tt> subclass itself, because
you might want to use the <tt class="CLASSNAME">
GtkNotebook</tt> in a <tt class="CLASSNAME">
GnomePropertyBox</tt>. The Gnome panel and the Gnome
menu editor use this widget.

<span class="STRUCTNAME">GtkAdjustment</span>
represents a numeric value. It can also store a maximum
and minimum value, a "step increment," a "page
increment," and a "page size." Some objects don't use
all the fields in the adjustment, and some interpret
them slightly differently. A <tt class="CLASSNAME">
GtkRange</tt> (including its <tt class="CLASSNAME">
GtkScale</tt> and <tt class="CLASSNAME">
GtkScrollbar</tt> subclasses) will allow the user to
move the slider between the minimum and maximum values.
Clicking the arrows on the end of a <tt class=
"CLASSNAME">GtkScrollbar</tt> nudges the scroll bar by
one "step increment"; clicking them with the middle
button moves one "page increment." The "page size"
determines the size of the scrollbar slider (it's the
length of the "visible" page in the same units as the
overall range). <span class="STRUCTNAME">
GtkAdjustment</span> emits signals when its values
change.
