Customizing Your Session
</A></H3>
<P>Although the default CDE session offers a lot, chances are you will want to customize
your environment. When it comes to configuration options, the architects of the CDE stayed
with the true UNIX spirit by supplying many different ways to accomplish the same thing.
Most configuration preferences can be altered to suit a user's taste with a few simple clicks of
the mouse; just about any aspect of the CDE can be managed through its configuration files at
an individual user level, that is, without altering the entire system. This allows power users to
tailor their environment as much as they want, while still giving less skilled users a very
comfortable environment.
</P>
<P>In addition, site administrators can easily tailor the desktop to suit their organization's
needs by setting up configuration defaults in a shared system area (usually
/etc/dt). Files in this area can not only make the necessary applications available, but they can also define what users
can and cannot alter on their desktop.
</P>

The Style Manager
</A></H4>
<P>The Style Manager is one of the most convenient features of the CDE. Most X Window
environments require changes to be made through the X resource configuration files, which is
too complicated for the average user. Others provide limited configurability through menus
and dialog boxes, such as modifying color schemes and basic window behavior, but still leave a
bit to be desired when compared to user-friendly systems such as Windows and Macintosh.
The CDE's Style Manager goes a long way toward addressing this issue.
</P>
<P>The Style Manager, shown in Figure 6.3, is launched from the Front Panel by clicking
the icon that resembles an artist's palette.
</P>
<BR>

The Style Manager.<BR>
<P>With the Style Manager, you can configure various attributes of the CDE using the following options:
</P>
<BR>
<a href="8brhu03.html"><img src="images/tn_8brhu03_jpg.jpg"></a><BR>
<UL>
<LI> Color—A color palette manager, which comes with more than thirty palettes
already defined. Because the CDE is based on the Motif window manager, color can
be changed dynamically. Therefore, you can view color changes as you select them.
In
</UL>
<A NAME="PAGENUM-82"><P>Page 82</P></A>
<UL>
<UL>
addition, you can add, delete, or modify palettes. Instead of specifying colors for
each display attribute (such as active window, inactive window, and so on), you can
adjust the palette with a set of slide controls that affect all aspects of the color scheme as one.
</UL>
</UL>
<UL>
<LI> Font—Enables you to set the default font size for all applications.
<LI> Backdrop—With this option, you can select a bitmap background from the
26 bitmaps that come with the desktop. For each virtual screen, you can choose
an individual background to help you keep track of which screen is active.
<LI> Keyboard—Offers the options to
choose whether keys will repeat when held and to enable a "click" sound for each keypress.
<LI> Mouse—The CDE offers a surprisingly complete set of options for the mouse.
You can switch buttons for left- or right-handedness, adjust the click speed, and set
the acceleration and threshold.
<LI> Beep—Allows you to adjust the volume, tone, and length of the default
"beep," usually intended as an alert or notifier of an error.
<LI> Screen—Offers you the option of setting the screen to automatically blank after
a specified period of inactivity. In addition, you can configure a screen saver that
is activated after a similar interval. The screen saver has all the familiar
xlock options, such as fireworks, fractals, and Conway's "game of life." The screen saver can also
be activated from the Front Panel lock control.
<LI> Window—Enables you to select window behavior, such as whether to activate
a window by placing the mouse over it or by clicking it.
<LI> Startup—The CDE's startup options are sometimes the source of confusion for
new users. This option enables you to select a "home session" or specify that the state
of the desktop when you last logged out be restored.
</UL>

The CDE cannot restore applications that were started from a command-line
session—only those that were started from a desktop application or menu.

The Front Panel
</H4>
<P>You can customize the Front Panel either from the desktop or by editing configuration
files. This section covers the methods available from the desktop. In the section "Advanced
Front Panel Customization," I will go over some of the configuration file settings.

The Workspace Manager
</A></H5>
<P>Unlike other versions of the CDE, TriTeal places a virtual window
manager (called the Workspace Manager) on the front of the toolbar. From this manager, windows can be
moved
</P>
<A NAME="PAGENUM-83"><P>Page 83</P></A>
<P>between virtual workspaces by clicking and dragging with the mouse. However, in
the Workspace Manager, windows cannot be dragged from the active workspace the way they
can in olvwm.
</P>
<P>You can configure the Workspace Manager by right-clicking it and selecting the
Properties menu entry. From the Properties dialog, you can remove the Workspace Manager from
the Front Panel. This will replace it with the default for all CDE versions—buttons that select
each virtual workspace. Other options include the number of virtual workspaces and how they
will be displayed within the Front Panel or its separate display window.
</P>
<H5><A NAME="ch06_ 9">Subpanels
</A></H5>
<P>The initial Front Panel configuration supplies three subpanels: Help, Personal Printers,
and Personal Applications. Adding panels is easy, as is adding additional icons to subpanels.
</P>
<P>To add a panel, right-click the icons over which the new panel will be added and select the
Add Subpanel option. A new panel is created, with two selections already defined: the icon that
was already on the Front Panel and an Install Icon selection.
</P>
<P>For example, add a subpanel above the Mail control. First, right-click (or left-click if your
mouse is in left-handed mode) the Mail icon immediately left of the virtual screen manager. A
small menu appears with three selections, the middle one being Add Subpanel. Select it by
pointing the mouse at it and releasing the button. An up arrow will appear above the Mail
icon. When you click this arrow, the subpanel pops up with the title Mail.
</P>
<P>In order to display the use of the Install Icon icon, start the Application
Manager by clicking the file drawer icon next to the Style Manager icon. The Application Manager window is
shown in Figure 6.4.
