How can I add an icon to the CDE Front Panel or remove an icon from the Front
Panel?

The CDE Front Panel is defined by a database of configuration files.  The
default Front Panel configuration is defined in:

/usr/dt/appconfig/types/C/dtwm.fp

Front Panel configuration files end with the extension ".fp".

By default, Front Panel configuration files are found in the following
directories:

$HOME/.dt/types/
/etc/dt/appconfig/types/C/
/usr/dt/appconfig/types/C/

Where there is a conflict between components of a definition, the following
rules apply:

+ If the components have the same name, the first component read is used
+ If two components specify the same position, the are placed in the order
  in which they are read

To remove a control from the Default CDE's Front Panel:

1.  Copy its definition from

    /usr/dt/appconfig/types/C/dtwm.fp

    into a file with the ".fp" extension residing in the directory:

    $HOME/.dt/types

2.   Add the following text to the control definition:

    DELETE      True

3.   Choose "Restart WorkspaceManager ..." from the root menu.

For example, to remove the Text Edit application from the Front Panel
copy its text from:

	/usr/dt/appconfig/types/C/dtwm.fp 

into

	$HOME/.dt/types/textedit.fp

then add the line:

DELETE  True

The control definition should look like:

CONTROL TextEditor
{
  TYPE                  icon
  CONTAINER_NAME        Top
  CONTAINER_TYPE        BOX
  POSITION_HINTS        4
  ICON                  Fppenpd
  LABEL                 Text Editor
  PUSH_ACTION           Dtpad
  DROP_ACTION           Dtpad
  HELP_TOPIC            FPOnItemTextEditor
  HELP_VOLUME           FPanel
  DELETE                True
}

Finally, choose "Restart Workspace Manager..." , from the root menu.  The
Text Editor will be removed from the Front Panel.

To add a system-wide Control to the Front Panel:

1.  Create and edit a file with the extension ".fp" in:

    /etc/dt/appconfig/types/C/

    Alternatively, to add a personal Control to the Front Panel, create and
edit
    a file with the extension ".fp" in:

    $HOME/.dt/types/


2.   Define a control in that file using the following syntax:

    COMPONENT {name}
    {
        {keyword} {value}
        {keyword} {value}
    ...
    }

    Refer to the /usr/dt/appconfig/types/C/dtwm.fp for examples of {name},
    {keyword} and {value}

3.   Choose "Restart Workspace Manager ..." from the root menu.

For example, to add a Load Meter to the Front Panel as the third item from
the left, follow these steps:

	A. Create and edit the file:

		$HOME/.dt/types/load.fp

	B. Define the following control:

		CONTROL LoadMeter
		{
		    TYPE                client
		    POSITION_HINTS      3
		    CONTAINER_NAME      Top
		    CONTAINER_TYPE      BOX
		    CLIENT_NAME         xload
		    CLIENT_GEOMETRY     88x64
		}


	C. Choose "Restart Workspace Manager..." , from the root menu.  
	The Load Meter will be displayed in the Front Panel.

How to add a newly created CDE action to a subpanel on dtwm's front
panel on system-wide level.

1. Create a system-wide front panel configuration file (as root) using 
   this naming convention:

   /etc/dt/appconfig/types/language/name.fp

   where "name" is the name of the file.  Please retain the ".fp" extension.

2. Define the system-wide control in the file.

   Use the CONTAINER_NAME and CONTAINER_TYPE fields to specify the container
   for the control:

   CONTROL control_name
   {
     CONTANINER_NAME  subpanel_name
     CONTANINER_TYPE  SUBPANEL

     ...
   }

   where "..." is the actual CONTROL specifications.

   Note:  To find subpanel_name, examine these
   files:

   + $HOME/dt/appconfig/*.fp
   + /etc/dt/appconfig/types/C/*.fp
   + /usr/dt/appconfig/types/C/*.fp
  
3. Save the configuration.

4. Exit CDE and login as any user. 


EXAMPLE: Allows for a cmdtool to start from the Personal Applications subpanel
         for all users on one system.

1. Create /etc/appconfig/types/C/cmd.fp

2. cmd.fp file has the following CONTROL definition:

   CONTROL cmdtool
   {
     TYPE           icon
     CONTAINER_NAME PersAppsSubpanel
     CONTAINER_TYPE SUBPANEL
     ICON           Dtactn
     PUSH_ACTION    cmdAct
     PUSH_RECALL    True
   }

   Since this control is associated with a PUSH_ACTION, the ACTION 
   cmdACT must be created.  It is best placed in same directory, with 
   a file extension of ".dt"  (/etc/appconfig/types/C/name.dt.  In 
   this example name.dt = cmd.dt).

   The cmd.dt file has the following ACTION definition:

   ACTION cmdAct
   {
     EXEC_STRING    /usr/openwin/bin/cmdtool
     WINDOW_TYPE   NO_STDIO 
   }

3. When finished with step two one should have both a cmd.fp and a 
   cmd.dt in the "system-wide" directory /etc/appconfig/types/C

4. Exit CDE and login as any user.  The Personal Applications subpanel 
   will have a Dtactn icon.  When this icon is selected, an
   OpenWindows cmdtool will appear.
