1. Introduction
The Plus! pack for Windows 95 adds many additional features to Windows - some
things that really should have been included with Windows 95 itself. One of
these is Desktop Themes. A Theme is a collection of sounds, icons, pointers
(cursors), along with wallpaper, colour and font settings and a screensaver.
Basically, it's all the things about the Windows interface you can configure
through the Control Panel, brought together into one package.
There are literally hundreds of Themes available, and until now you needed
the Plus! pack to use them. Without it, it was necessary to install all the
components manually, a difficult and time-consuming process. Then, if you
didn't like the finished product, you had to manually change all your
settings back again.
The Desktop Themes application is a direct replacement for the Desktop Themes
control panel provided with the Plus! pack. It offers the same functionality
as the Plus! version with a few additional features. Even if you have Plus!
you might want to consider switching to using Desktop Themes for the additional
features.
2. About Themes
A Theme is described by a .theme file, which is basically a .INI file
containing all the settings for that particular theme. Desktop Themes can read
this file and make all the necessary configuration changes in one hit.
You can find hundreds of themes on the net. Some good places to start looking
are:
Dale's Windows95 Themes Page http://www.bitshop.com/~dale/
Windows95.com http://www.windows95.com/apps/desktop.html
Gionet's Win95 Plus Themes http://www.95themes.com/
Spike's Windows 95 Themes Page http://www.algonet.se/~spike/
3. Installation
No special installation is necessary to run Desktop Themes - simply copy the
.EXE to wherever you want to keep it (eg C:\Program Files). You can then
create a shortcut to it and put this on your Desktop, in your Start menu, etc.
The first time you run Desktop Themes, it looks to see if Plus! themes have
already been installed on your system. If they haven't, a dialog appears
prompting you to create a directory to store themes in. This is necessary for
the proper functioning of the program.
The theme path defaults to "c:\Program Files\Plus!\Themes", because this is
what Plus! itself uses. If you ever install Plus! in the future, the themes
you currently have installed should work with no input from you. You can,
however, store the themes anywhere you like.
Desktop Themes also adds two items to the context menu for Theme files -
Apply Settings, and Install Theme. Once these is installed, you can apply a
theme instantly by right-clicking on it and choosing Apply Settings (or by
double-clicking on its icon). You can install a theme by right-clicking on it
and choosing Install Theme.
Themes that you install with Desktop Themes can automatically be uninstalled,
either using Desktop Themes, or with the Add & Remove Programs control panel.
For this to work, the Desktop Themes executable must remain in the place it
was when it was first run. That is, you should copy it to its 'final resting
place' before running it for the first time. If you move the Desktop Themes
executable after it has installed itself, you can update the context menus
by clicking the 'Update' button on the Miscellaneous page. However, any themes
you have installed will no longer be uninstallable from Add & Remove Progrems
(uninstalling them through Desktop Themes will still work).
If you have previously installed the 'Theme Installer' application by the
same author, you should remove this (by double-clicking on its icon again).
Desktop Themes completely replaces Theme Installer as the installer/uninstaller
for themes.
4. Usage
Start the Desktop Themes app by double-clicking on its icon. A dialog will
appear containing several pages, the first of which allows you to select a
theme from those installed.
A drop-down list is used to choose a theme. The initial selection is
"(current settings)" which refers to the current configuration of your
desktop. Immediately below this in the list is "(original settings)", which
refers to the configuration when Desktop Themes was run (to start with, the
current and the original settings are the same). You can always return to
the original settings using this selection, which allows you to undo any
changes you have made (as the Cancel button does not undo the effects of
pressing Apply).
The "Save As" button allows you to save the current settings to a new theme.
You can use this to preserve your configuration before you start playing with
new ones. You can also use it to create themes to distribute to other people.
The "Active Components" list allows you to choose which components in the
currently loaded theme will be installed in your system when you choose Apply
or Ok. By default they are all switched on, meaning that a new theme will
totally overwrite your existing settings. You can selectively disable parts of
the theme through these switches.
To look at a new theme you have downloaded, you must first unzip it and install
it. See the next section for information about this.
Of the other pages in this dialog, "Display", "Sounds" and "Pointers" allow
you to see or hear the various components of the theme before installing it.
Each page contains a list of components - for the graphical ones, just click
on its name to display it. To hear a sound, select the appropriate sound by
name and click the play button.
The "Miscellaneous" page contains several additional options that Plus!
provides. Some of these might not work on a standard Windows 95 system, but
feel free to play around with them. The "Stretch desktop wallpaper to fit the
page" feature is emulated by Desktop Themes, but some of the others seem to
require Plus! to work.
This page also has a field labelled "Path to Themes". You can use this to
modify the path that themes are stored in. If you enter a directory that does
not exist, it will be created automatically.
The "Install" page is discussed in the next section.
The "About" page displays some information about the program and the author.
5. Installing Themes
The "Install" page allows you to install a new theme. Themes are usually
distributed in ZIP format, so you must unzip the theme to a temporary directory.
You MUST use a ZIP program that supports long filenames (like WinZip). Once
you have done this, you must enter the full name of the .theme file in the
Install page. Use the Browse button to help you find it.
Themes that have been installed with Desktop Themes can also be uninstalled
automatically. To uninstall a theme, select it in the list and click the
Uninstall button. You can also uninstall themes via the Add & Remove Progrems
control panel.
Some third-party themes are not constructed correctly. The .theme file which
contains the references to the theme components uses a notation that allows
non-specific path names for components. For example, it can specify :
%themedir%MyTheme\MyComputer.ico
instead of
c:\Program Files\Plus!\Themes\MyTheme\MyComputer.ico
This means that wherever your themes directory is on your system, the theme
will still be able to find its components.
Some themes do not use the %themedir% notation - instead, they use absolute
paths to theme components, often paths on the theme author's own system.
You might see something like :
d:\work\mytheme\MyComputer.ico
This is plainly not going to work on any computer other than the theme
author's.
A future version of Desktop Themes will try to get around this problem. For
the mean time, themes that are not constructed correctly will not work.
6. Wallpaper Notes
Support for JPEG Wallpaper files in Desktop Themes is implemented by
converting the JPEG to a temporary BMP file. If you Apply a theme that uses a
JPEG for wallpaper, the picture is converted to a permanent BMP file in your
Windows directory. This file is overwritten each time you Apply a theme that
uses JPEGs, so you only ever have the one converted picture. Since BMP files
take much more room than JPEGs, you should ensure you have enough space on
your Windows drive (approximately 3mb is required for an average size 24bit
picture). This is the same mechanism as Plus! uses.
The JPEG conversion itself requires about 1mb of memory - if a wallpaper
isn't appearing, and it's a JPEG file, then you probably do not have enough
memory. In this case, try closing some open applications and try again.
Desktop Themes also emulates the Wallpaper stretching that Plus! performs.
This is very useful as it allows you to use practically any size bitmap to
fill your screen, instead of leaving an ugly border around the outside.
Unfortunately, Desktop Themes' stretching isn't as transparent as Plus!'s is;
it has to convert the original size image to a BMP file in your Windows
directory (much like the JPEG conversion - of course if you are stretching a
JPEG file you only get the one BMP!). This can take a bit of time, and requires
some hard drive space. It generally works very well though.
Because stretching is implemented via a converted BMP file, if you change
screen resolution the stretched image will no longer be the correct size.
To remedy this, run Desktop Themes and select the Miscellaneous tab. Turn off
'Stretch wallpaper to fit the screen' and click the Apply button. Then turn it
back on and click the Apply button again. You will also have to do this if you
change Wallpaper through the Display Properties, and want to stretch it to full
screen.
7. Other Notes
Desktop Themes allows you to undo any changes you have Applied, unlike the
original Plus! control. Use the "(original settings)" item in the theme
selection list to return to the settings you had when you ran Desktop Themes.
If you have Plus! installed when you run Desktop Themes, it won't install itself
in the registry as the default theme handler. If you decide you want to switch to
using Desktop Themes, just go to the "Miscellaneous" page and click the "Update"
button. This will force it to install itself as the default handler, overrinding
Plus!.
8. Uninstalling
To uninstall the Desktop Themes application, simply delete the file. To
uninstall themes themselves, use either the "Install" page of Desktop Themes,
or the Add & Remove Programs control panel.
9. Future Enhancements
In future versions I plan to add the ability to configure the various theme
components, thus providing a fully integrated editing/previewing interface.
