props - Change OpenWindows settings SYNOPSIS
props [ generic-tool-arguments ] DESCRIPTION
props can be used to change certain settings for OpenWindows/XView programs using a GUI. As most of these settings are stored in OpenWin- dows-specific X resources, they won't have an influence on non-OpenWindows programs. These are the settings that can be modified using props (their meaning is explained in xview (7)): OpenWindows.Beep OpenWindows.DragRightDistance OpenWindows.IconLocation OpenWindows.MultiClickTimeout OpenWindows.PopupJumpCursor OpenWindows.ScrollbarPlacement OpenWindows.SelectDisplaysMenu OpenWindows.SetInput OpenWindows.WindowColor OpenWindows.WorkspaceColor Scrollbar.JumpCursor *displayLang: C *timeFormat: C *basicLocale: C *inputLang: C *numeric: C OPTIONS
generic-tool-arguments props accepts the XView generic tool arguments described in xview (7). FILES
~/.Xdefaults Stores user's resource values. Modified by props when new settings are applied. AUTHOR
This manual page was written by Martin Buck <mbuck@debian.org> for Debian GNU/Linux. SEE ALSO
xview(7) BUGS
props saves all resources currently defined in the X server to ~/.Xdefaults, overwriting its current contents. This will remove comments and conditionals, reorder resources and also save resources which were originally loaded into the server by other means. The color selector is available only on display classes GrayScale, PseudoColor and DirectColor. XView Version 3.2p1 props(1)
