5.6 The settings dialogue - customise your chesspp
Chess++ is a highly customisable software system. You can
set up any colour combination you like for the window itself, chess board,
and pieces which includes transparency for the board and pieces.
You can use different textures in the OpenGL game widget.
There are different languages you can choose from and there is
even a themeing system that allows you to save and export your
settings to share them with other users.
Most of these settings are adjustable via the chesspp settings dialogue.
The dialogue is divided into tabs and subtabs
(see figure 5.5)
which group settings according to the part of the application, they are related to.
Tabs and GL Widget subtabs of the Chess++ settings dialogue.
Most of the settings affect the OpenGL widget.
5.6.1 Chess display settings of the OpenGL widget
You can adjust game display in many ways. You
can set up different colours for black and white pieces,
squares, and use a coloured background.
Pieces and squares can be decorated with textures
that you can load from images on your machine.
Moves can be animated so that the pieces seem
to disappear and reappear on the target square
of their move.
Setup tab for transparent squares and pieces.
18.104.22.168 Transparency settings
"Activate piece transparency" has to be checked in order to have
pieces displayed transparently. As stated in the dialogue, this
involves sorting all objects in the scene. (Transparent objects
that are closer to the viewing plane have to be rendered after
those objects that are farther away when using transparency
effects with alpha blending.)
If you have a very slow machine, you might want to switch
piece transparency off, to achieve higher frame rates.
You can also display pieces as wireframe objects, which also
gives them a somewhat transparent look, while piece transparency doesn't
have to be activated.
22.214.171.124 Colour settings
Colours, and also transparency values, can be adjusted using the colour chooser
dialogues in the colour setup (see
that appear when clicking "Change" for one of the values.
Settings tab for colouring the board and pieces.
The alpha value you can set up there, is the value for opacity (and so the
reciprocal value of transparency).
You shouldn't confuse the background colours, you can adjust here
with those for the main window. These here only affect the OpenGL widget.
To display the background coloured, instead of black, you have
to activate the checkbox "Show background" in the properties tab.
126.96.36.199 Animation settings
Moves can be animated by making pieces dissolve and then reappear
on their target square. Selected squares can be highlighted
Settings tab for animation sequences.
(in addition to simple colouring) with a pulsating colouring.
In the animation subtab of the settings dialogue (see
you can set up the step size for every animation scene and the timer step size.
Increasing the timer step size slows down animations (as it reduces
the frame rate), while increasing the other step sizes increases
the speed of the resepctive animation.
5.6.2 Main window display settings
The Chesspp main window can be set up to use a freely configurable
palette for background, buttons, text etc. or to simply use the palette
of your window manager. Figure 5.9
displays the subtab of the settings window where you can adjust the colours.
Properties tab for main window colours and start screen.
You can also set up a start screen image that will be displayed in the OpenGL
widget while you are not connected to a server or don't play a game.
Tab for selection and export of themes.
188.8.131.52 Chess++ theme import and export
You can save your palette settings and all settings concerning game display
to a file using the subtab shown in
Here you can also import so-called themes using the "Import" button
or by configuring the path where
to search for theme files.
If you use the "Import" button, the theme file will be copied to your
Theme files always end with .cpt
. Please make sure that
you have write permissions to your theme path if you want
to use the import function.
If you want to use a theme file from the list of
available themes, select it from the list and click "Use selected theme"
or simply double-click the item,
and then "Apply" or "Ok".
5.6.3 Settings of the chat widget
The chat and command prompt widget can be modified in its
look using the settings tab shown in
Settings of the chat and command prompt widget.
Here you can adjust the color for messages you send, messages you receive and
messages like hints from Chesspp or the server you are connected to.
Time stamps can get added to every chat message and you can switch
special formatting features for the chat on and off.
Check "Use BBCode" if you want to enable the BBCode-like markup
for chat messages (as described in
If you do not activate this option, all BBCode commands will simply
