    This article contains a listing of known keys that can be used with Kiosk and what they do. How to actually use these keys and other capabilities of Kiosk such as URL restrictions, creating assigning profiles, etc. is covered in the [[../Introduction|Introduction to Kiosk]] article.
    {{Moved To Userbase}}
     
    Which configuration file to put these entries in depends on whether you wish to make them global to all applications or specific to one application. To make the restrictions valid for all applications, put them in {{path|kdeglobals}}. To enable a restriction for a specific applications place them in the application-specific configuration, e.g. {{path|konqererorrc}} for Konqueror.
     
    == Application Action Restrictions ==
     
    === KCalc ===
     
    === Konqueror and Desktop ===
     
    === Konsole ===
     
    === KWin ===
     
    {|
    |-
    ! Key !! Action
    |-
    |-
    | action/kwin_rmb || Context menus on window titlebar and frame
    |}
     
    === Panels ===
     
    {{improve|revisit this when plasma is providing the panels}}
     
    === Using D-Bus To Find More Actions ===
     
    == Authorizing {{path|.desktop}} Files ==
     
    Application {{path|.desktop}} files can have an additional field <tt>X-KDE-AuthorizeAction</tt>.
     
    If this field is present the {{path|.desktop}} file is only considered valid if the action(s) mentioned in this field has been authorized. If multiple actions are listed they should be separated by commas (',').
     
    If the {{path|.desktop}} file of an application lists one or more actions this way and the user has no authorization for even one of these actions then the application will not appear in the KDE menu, will not allow execution via that {{path|.desktop}} file and will not be used by KDE for opening files of associated mimetypes.
     
    == File Dialog ==
     
    These keys disable actions that are found in the KDE file dialog. To use them, create a section in {{path|kdeglobals}} that looks like this:
     
    <code ini>
    [KDE Action Restrictions[$i]
    action/<key>=false
    </code>
     
    {|
    |-
    ! Key !! Action
    |-
    |-
    | action/home || Go to home directory
    |-
    | action/up || Go to parent directory
    |-
    | action/back || Go to previous directory
    |-
    | action/forward || Go to next directory
    |-
    | action/reload || Reload directory
    |-
    | action/mkdir || Create new directory
    |-
    | action/toggleSpeedbar || Show/hide sidebar
    |-
    | action/sorting menu || Sorting options
    |-
    | action/short view || Select short view
    |-
    | action/detailed view || Select detailed view
    |-
    | action/show hidden || Show/hide hidden files
    |-
    | action/preview || Show/hide preview
    |-
    | action/separate dirs || Show/hide separate directories
    |}
     
    == Printing ==
     
    There are several keys that restrict various aspects of the KDE print dialog and printing system. To use them, create a configuration section like this:
     
    <code ini>
    [KDE Resource Restrictions][$i]
    print/<resource key>=false
    </code>
     
    Note how each of the printing keys start with <tt>print/<tt> in the configuration file.
     
    ;print/copies
    :Disables the panel that allows users to make more than one copy.
     
    ;print/dialog
    :Disables the complete print dialog. Selecting the print option will immediately print the selected document using default settings. Make sure that a system wide default printer has been selected. No application specific settings are honored when this restriction is activated.
     
    ;print/options
    :Disables the button to select additional print options.
     
    ;print/properties
    :Disables the button to change printer properties or to add a new printer.
     
    ;print/selection
    :Disables the options that allows selecting a (pseudo) printer or change any of the printer properties. Make sure that a proper default printer has been selected before disabling this option. Disabling this option also disables <tt>print/system</tt>, <tt>print/options</tt> and <tt>print/properties</tt>.
     
    ;print/system
    :Disables the option to select the printing system backend, e.g. CUPS. It is recommended to disable this option once the correct printing system has been configured.
     
    == Resource Restrictions ==
     
    KDE applications can take advantage of many types of resources such as configuration data, caches, plugin registries, etc. These are loaded from both system-wide as well as from per-user locations on disk. It is possible to restrict use of the per-user resources directories, preventing users from adding to or altering existing shared resources.
     
    This is accomplished by creating a section like this in a configuration file:
     
    <code ini>
    [KDE Resource Restrictions][$i]
    <resource key>=false
    </code>
     
    The following resources can be used as keys and controlled in this manner:
     
    {|
    |-
    ! Key !! Directory !! Provides
    |-
    |all || n/a || All resources listed in this table
    |-
    |autostart || {{path|share/autostart}} || Apps to start on login
    |-
    |data || {{path|share/apps}} || Application data
    |-
    |data_&lt;appname&gt; || {{path|share/apps}} || Application data for the application named &lt;appname&gt;
    |-
    |html || {{path|share/doc/HTML}} || HTML files
    |-
    |icon || {{path|share/icon}} || Icons
    |-
    |config || {{path|share/config}} || Application configurations
    |-
    |pixmap || {{path|share/pixmaps}} || Images
    |-
    |xdgdata-apps || {{path|share/applications}} || Application .desktop files
    |-
    |sound || {{path|share/sounds}} || Sound files
    |-
    |locale || {{path|share/locale}} || Localization data
    |-
    |services || {{path|share/services}} || Protocols, plugins, kparts, control panels, etc. registry
    |-
    |servicetypes || {{path|share/servicetypes}} || Plugin definitions, referenced in services registry entries
    |-
    |mime || {{path|share/mimelnk}} || Mimetype definitions
    |-
    |wallpaper || {{path|share/wallpapers}} || Desktop wallpaper images
    |-
    |templates || {{path|share/templates}} || Document templates
    |-
    |exe || {{path|bin}} || Executable files
    |-
    |lib || {{path|lib}} || Libraries
    |}
     
    == Screensavers ==
    In {{path|kdeglobals}} in the <tt>[KDE Action Restrictions]</tt> group:
     
    ;opengl_screensavers
    :defines whether OpenGL screensavers are allowed to be used.
     
    ;manipulatescreen_screensavers
    :defines whether screensavers that manipulate an image of the screen (e.g. moving chunks of the screen around) are allowed to be used.
     
    === Automatic Log-out ===
    In {{path|kscreensaverrc}}:
     
    <code ini>
    [ScreenSaver]
    AutoLogout=true
    AutoLogoutTimeout=600
    </code>
     
    The timeout is the time in seconds that the user must be idle for before the logout process is automatically started. Be careful with this capability as it can lead to data loss if the user has unsaved files open.
     
    == Session Capability Restrictions ==
     
    These keys apply to various capabilities associated with a desktop session and are not application specific. To use them, create a section in {{path|kdeglobals}} that looks like this:
     
    <code ini>
    [KDE Action Restrictions][$i]
    <key>=false
    </code>
     
    ;custom_config
    :Whether the <tt>--config</tt> command line option should be honored. The <tt>--config</tt> command line option can be used to circumvent locked-down configuration files.
     
    ;editable_desktop_icons
    :define whether icons on the desktop can be moved, renamed, deleted or added. You might want to set the path for the desktop to some read-only directory as well instead of {{path|$HOME/Desktop}}.
     
    ;lineedit_text_completion
    :Defines whether input lines should have the potential to remember any previously entered data and make suggestions based on this when typing. When a single account is shared by multiple people you may wish to disable this out of privacy concerns.
     
    ;lock_screen
    :whether the user will be able to lock the screen.
     
    ;logout
    :whether the user will be able to logout from KDE.
     
    ;movable_toolbars
    :define whether toolbars may be moved around by the user. See also <tt>action/options_show_toolbar</tt>.
     
    ;run_command
    :whether the "Run Command" (Alt-F2) option is available.
     
    ;run_desktop_files
    :defines whether users may execute desktop files that are not part of the default desktop, KDE menu, registered services and autostarting services.
    * The default desktop includes the files under {{path|$KDEDIR/share/kdesktop/Desktop}} but '''not''' the files under {{path|$HOME/Desktop}}.
    * The KDE menu includes all files under {{path|$KDEDIR/share/applnk}} and {{path|$XDGDIR/applications}}
    * Registered services includes all files under {{path|$KDEDIR/share/services}}
    * Autostarting services include all files under {{path|$KDEDIR/share/autostart}} but '''not''' the files under {{path|$KDEHOME/Autostart}}
     
    ;shell_access
    :Whether a shell suitable for entering random commands may be started. This also determines whether the "Run Command" option (Alt-F2) can be used to run shell-commands and arbitrary executables. Likewise, executables placed in the user's Autostart folder will no longer be executed. Applications can still be autostarted by placing <tt>.desktop</tt> files in the {{path|$KDEHOME/Autostart}} or {{path|$KDEDIR/share/autostart}} directory. See also <tt>run_desktop_files</tt>.
     
    :You probably also want to activate the following resource restictions:
    *"appdata_kdesktop" - To restrict the default desktop.
    *"apps" - To restrict the KDE menu.
    *"xdgdata-apps" - To restrict the KDE menu.
    *"services" - To restrict registered services.
    *"autostart" - To restrict autostarting services.
    :Otherwise users can still execute .desktop files by placing them in e.g. {{path|$KDEHOME/share/kdesktop/Desktop}}
     
    ;skip_drm
    :defines if the user may omit DRM checking.
     
    ;start_new_session
    :defines whether the user may start a second X session. See also the documentation on [http://docs.kde.org/en/HEAD/kdebase/kdm/ kdm configuration].
     
    ;switch_user
    :defines whether user switching via kdm is allowed.  See also the documentation on [http://docs.kde.org/en/HEAD/kdebase/kdm/ kdm configuration].
