NAME

dtstyle - the Common Desktop Environment Style Manager

SYNOPSIS

dtstyle

NOTE: There are no style manager specific options that can be specified in the command line. 

DESCRIPTION

Dtstyle provides interactive customization of visual elements and system behavior for the desktop through the style manager. 

This component consists of the UI and supporting code that allows the end user to interactively customize most of the visual elements and system behavior for the CDE. This component also helps define some resource utilization conventions. The style manager’s main window which consists of an iconic interface is invoked from the Front Panel.  The style manager window contains icons representing customization in several areas. 

Key Supported Tasks

Colors
Sets the color palette that is used for window colors in the workspace.

FontsSets the application font sizes as applications are started. 

BackdropSets the backdrops for workspaces. 

KeyboardSets the keyboard’s key click volume and character repeat capability. 

MouseSets the mouse button click settings, double-click speed, pointer acceleration and pointer movement threshold. 

AudioSets the beeper volume, tone, and duration. 

ScreenSets the screen lock and time-out intervals, chooses the screen saver client(s) to be run at time out and/or screen lock and previews the selected screen saver client(s) for the user. 

WindowSets the window focus policy, window raise policy and iconification policy (in an icon box or on the desktop). 

StartupSets the session startup policy. 

OPTIONS

There are no style manage specific options that can be set from the command line. 

RESOURCES

Style Manager specific resources

The style manager used the following resources to control its appearance and behavior. 

Name                    Class                   Type      Default

paletteDirectories      PaletteDirectories      string    NULL

writeXrdbImmediate      WriteXrdbImmediate      Boolean   true

paletteDirectories

Specifies a list of the directories (separated by spaces) where additional color palettes are located. These palette files are used to generate the list of color palettes that a user may select from in the Color dialog. In addition to this list palettes are also searched for in /usr/palettes and $HOME/.dt/palettes. If there is a name clash the palettes in $HOME/ .dt/palettes override the ones in /usr/palettes and also the ones present in any other directories which may have been specified by the paletteDirectories resource. 

writeXrdbImmediate

Controls when new font size or new mouse double-click time resources are used. If True, new resources are used when new clients start. If False, new resources are used at the next session (after logout, with "Resume Current Session" selected in the Startup dialog).

Color and backdrop resources: Global to the desktop

The following resources are used by more than one desktop component. The syntax for specifying global resources is: ∗resource_id. 

Name                  Class                  Type    Default

backdropDirectories   BackdropDirectories    string  see below

colorUse              ColorUse               int     dynamic∗

dynamicColor          DynamicColor           Boolean true

foregroundColor       ForegroundColor        int     dynamic∗

shadowPixmaps         ShadowPixmaps          int     dynamic∗

writeXrdbColors       WriteXrdbColors        Boolean true

 NOTE: The display type determines default. 

backdropDirectories

Specifies location of directories (colon separated) for the backdrops which appear in the Backdrop dialog.  This resource is also used by dtwm. The backdrops in the specified directory or directories are displayed in the backdrop dialog along with the system default backdrops. 

ColorUse

Specifies the number of colors to use for the user interface. The default value for this resource is determined by querying the X server for the number of color cells on the system. Valid values are: B_W" - Specifies a black and white system. The color palettes use only Black and White (color cells 0 and 1) and icons are displayed as bitonal images. In this configuration four color palettes are available: Black, White, BlackWhite and WhiteBlack. These palettes do not dynamically change. To change a palette, the session must be restarted.  This resource value forces shadowPixmaps to True, and foregroundColor to either black or white depending on the palette chosen.  LOW_COLOR" - Specifies a low color system. The color palettes use 2 color sets and icons are displayed as bitonal images. The number of color cells can be further reduced by using the resources shadowPixmaps and foregroundColor.  MEDIUM_COLOR - Specifies a medium color system. The color palettes use 4 color sets and icons are displayed as bitonal images.  The number of color cells can be further reduced by using the resources shadowPixmaps and foregroundColor.  HIGH_COLOR - Specifies a high color system. The color palettes use 8 color sets and icons are displayed as multi-color images. The number of color cells can be reduced by using the resources shadowPixmaps and foregroundColor.

dynamicColor

This resource can have values of True or False. dynamicColor is used to reduce the number of color cells being used. Once a palette has been selected and it is not likely to be changed, dynamicColor can be set to False. If set to False colors cannot be dynamically changed using the Style Manager. A selected palette will take effect the next session. The next time the session comes up, the color server uses Read Only color cells that can be shared by all clients, thus reducing the number of color cells used. 

foregroundColor

This resource can have values of White, Black or Dynamic.  foregroundColor causes all text (foreground) to use either pixel 0 or 1 (Black or White) or to have a color cell dedicated to foreground that changes in response to the background color (Dynamic) for each ColorSet. If set to White or Black, the number of color cells used per ColorSet is reduced by 1. 

shadowPixmaps

For color systems, this resource can have a value of True or False. If True, topShadowColor and bottomShadowColor use the same pixel as background and topShadowPixmap and bottomShadowPixmap are specified instead of solid color to create the 3D look. This reduces the number of color cells per ColorSet by 2.  shadowPixmaps defaults to True for systems with 4 or less color planes (16 or less color cells), and False for systems with more than 4 color planes. 

writeXrdbColors

This resource should only be used if non desktop Motif clients are to be run that have color schemes that conflict with the desktop colors.  This resource has no impact on clients linked with the desktop Motif library. This resource specifies whether color resource information should be written out. If set to False, background and foreground resources are not written out with the values of the current palette.  This means that the above-mentioned clients do not get the desktop colors when they are started. The default value is True. 

Color resources: client specific

The following resources are specified on a per client basis. The syntax for specifying client-specific resources is: client_name_or_class∗resource_id. 

Name                 Class                  Type    Default

primaryColorSetId    PrimaryColorSetId      int     3

secondaryColorSetId  SecondaryColorSetId    int     4

primaryColorSetId

This resource specifies the primary color for an application. The primary color is used for the main background areas of the application and all children of the main area. The value of this resource is a number from one to eight that represents a specific color set in a palette. 

secondaryColorSetId

This resource specifies the secondary color for an application. The secondary color is used for the menubar and all menus and dialogs of the application. This allows dialogs on the screen to be visually associated with their parent applications by matching the dialog color to the menubar. The value of this resource is a number from one to eight that represents a specific color set in a palette. 

Color resources: dtwm specific

 The following are dtwm-specific resources. 

Name                  Class                Type    Default

activeColorSetId      ActiveColorSetId     int     1

inactiveColorSetId    InactiveColorSetId   int     2

activeColorSetId

Specifies the active frame color for dtwm. The value of this resource is a number from one to eight, which represents a specific color set in a palette. 

inactiveColorSetId

Specifies the inactive frame color for dtwm. The value of this resource is a number from one to eight, which represents a specific color set in a palette.

ENVIRONMENT

DTSCREENSAVERLIST

This environment variable specifies the names of the available screen saver actions (separated by a blank space). Using this variable allows the style manager to query the actions data base and display a list of the available screen saver clients for the user and to invoke screen saver actions for preview of selected screen savers. 

BROADCAST MESSAGES

Dtstyle invokes actions to inform interested applications about color and font changes. The notification group is DT_ENV_CHANGE and the notify messages are COLOR and FONT.
