DESCRIPTION
The dtfpfile front panel database provides definitions for the components
that define the content and functionality of the front panel. Files
containing front panel definitions must end with the .fp suffix. Like the
action and data type database, the front panel database is constructed by
reading all files ending in the .fp suffix found in the search path
specified by the DTDATABASESEARCHPATH environment variable.
See dtdtfile(4) for a complete description of the directory locations where
these database files are found and for a description of the specific syntax
for the database files.
File Format
The general syntax of the front panel configuration files is as described
above in the SYNOPSIS section of this man page. follows:
set DtDbVersion=version_number
set VariableName=variable_value
RecordType record_name
{
# Comment
Keyword Value
Keyword Value
.
.
.
}
The Comments, Versions and Variables fields are described in dtdtfile(4).
The front panel record types each have a set of Keyword and Value pairs.
There are six record types defined: PANEL, BOX, SUBPANEL, SWITCH, CONTROL
and ANIMATION. Each record type has a set of keywords defined for it. Many
of the keywords are used for multiple record types.
Record Types
PANEL front panel name
The PANEL record type defines the outermost container of the front
panel. It can contain one or more BOXes and optionally repositioning
handles, a menu and a minimize button. The keywords defined for PANEL
are described in the following table.

Keyword and Value Descriptions
The following list contains a description of each of the keywords defined
by the front panel.
ALTERNATE_ICON
Used with record types of: CONTROL.
Used with control types of: busy and icon.
ALTERNATE_ICON defines an image to be used to replace the normal image
within a control with a mail or file value for the MONITOR_TYPE. The
image is displayed when the file being monitored changes. For the busy
control, ALTERNATE_ICON is cycled with ICON to give the blinking
effect.
ANIMATION
Used with record types of: ANIMATION.
Used with control keywords of: PUSH_ANIMATION and DROP_ANIMATION.
ANIMATION defines a sequence of images to be displayed for either a
PUSH_ACTION or DROP_ACTION. Each animation within the list is
displayed in order with a default time separation of 200 milliseconds.
For a slower or faster sequence, the image name value can be followed
by the amount of time to display the image. If no time value is
specified, the previously specified value is used.
CLIENT_GEOMETRY
Used with record types of: CONTROL.
Used with control type of: client.
Used with control keywords of: CLIENT_NAME.
CLIENT_GEOMETRY specifies the size (in pixels) needed for the window of
a client displayed within the front panel.
CLIENT_NAME
Used with record types of: CONTROL.
Used with control types of: client or icon.
Used with control keywords of: PUSH_RECALL.
CLIENT_NAME specifies a name used to associate a control with an
executable. It is necessary for control types of client (an X client
running within the front panel) and for icon when the keyword
PUSH_RECALL is True. The value "client name" is the name of the
executable or can be set via a command-line argument for some clients
(such as xterm -name panelterm). The "client name" for a running
client can be found by executing xprop. The first string of the
WM_CLASS property is the value used.
CONTAINER_NAME
Used with record types of: BOX, SUBPANEL, SWITCH and CONTROL.
CONTAINER_NAME associates a component with its parent. For example,
the CONTAINER_NAME value for a SWITCH tells the front panel into which
BOX it should be placed. Since controls can reside in several different
component types, CONTAINER_NAME is used in conjunction with
CONTAINER_TYPE to define a control's parent.
CONTAINER_TYPE
Used with record types of: CONTROL.
CONTAINER_TYPE defines a control's parent type. This is used to
identify a control uniquely so that it can be created within the proper
parent.
CONTROL_BEHAVIOR
Used with record types of: PANEL.
CONTROL_BEHAVIOR provides the mechanism for setting the user model for
front panel controls. Controls can be set to invoke their PUSH_ACTION
by either a single or double click.
CONTROL_INSTALL
Used with record types of: SUBPANEL.
CONTROL_INSTALL enables or disables dynamic control installation into
subpanels. A value of True causes the control installation area to be
displayed within the subpanel.
DATE_FORMAT
Used with record types of: CONTROL.
Used with control types of: date.
DATE_FORMAT specifies the layout of the date string for a control of
type date. The format is the same used by the UNIX strftime(3)
function.
DELETE
Used with record types of: BOX, SUBPANEL, SWITCH and CONTROL.
DELETE is used to override and remove a non-locked component from the
front panel. This is necessary to eliminate system default front panel
components without replacing the default files. To use DELETE, a copy
of the component definition with the additional DELETE keyword is
stored in a file with an .fp suffix in the user's or application type's
directory.
DISPLAY_CONTROL_LABELS
Used with record types of: PANEL.
DISPLAY_CONTROL_LABELS specifies whether the controls contained within
the front panel's boxes have their labels displayed.
DISPLAY_HANDLES
Used with record types of: PANEL.
If DISPLAY_HANDLES is set to True, the move handles are displayed along
the left and right edges of the front panel.
DISPLAY_MENU
Used with record types of: PANEL.
If DISPLAY_MENU is set to True, and DISPLAY_HANDLES is also set to
True, the system menu button is displayed in the upper left hand corner
of the front panel.
DISPLAY_MINIMIZE
Used with record types of: PANEL.
If DISPLAY_MINIMIZE is set to True, and DISPLAY_HANDLES is also set to
True, the minimize button is displayed in the upper right hand corner
of the front panel.
DROP_ACTION
Used with record types of: CONTROL.
DROP_ACTION specifies the function that is invoked when a drop occurs
on the control.
DROP_ANIMATION
Used with record types of: CONTROL.
Used with all control types except: client.
DROP_ANIMATION specifies the name of an animation record to be
displayed when a drop occurs on the control. The control must have a
DROP_ACTION defined for the animation to be used.
FILE_NAME
Used with record types of: CONTROL.
Used with control types of: icon and file.
For the control type of file, FILE_NAME is the pathname of the file to
be used for the control. The file's file type, actions and images are
extracted from the action database for the control.
For MONITOR_TYPE mail and file, FILE_NAME specifies the pathname of the
file the front panel monitors for either mail arrival or some other
user-defined data.
For MONITOR_TYPE file, the ALTERNATE_ICON image is displayed when the
monitored file is non-empty. The ICON image is displayed if the file
is empty or non-existent.
For MONITOR_TYPE mail, the ALTERNATE_ICON image is displayed when the
file increases in size.
HELP_STRING
Used with record types of: PANEL, BOX, SUBPANEL, SWITCH and CONTROL.
HELP_STRING specifies an on-line help string to display when help is
requested over a front panel component. Since each component type can
have a help string associated with it, there is a precedence used in
deciding which help string to display. Control help takes precedence
over box help, switch help and subpanel help. Box help takes precedence
over subpanel help. The HELP_STRING value is used only if no HELP_TOPIC
value is defined.
HELP_TOPIC
Used with record types of: PANEL, BOX, SUBPANEL, SWITCH and CONTROL.
HELP_TOPIC specifies an on-line help topic that is used with either the
default help volume or a help volume specified by the HELP_VOLUME
keyword to display help information when requested over a front panel
component. Like the HELP_STRING keyword, each component type can have a
help topic associated with it and the same precedence rules are used.
HELP_VOLUME
Used with record types of: PANEL, BOX, SUBPANEL, SWITCH and CONTROL.
When HELP_VOLUME is used in conjunction with HELP_TOPIC, it defines the
help information to be displayed for a front panel component.
ICON
Used with record types of: CONTROL.
Used with control types of: icon, file and busy.
ICON specifies the image to be displayed within a control.
LABEL
Used with record types of: CONTROL.
Used with control types of: icon, file, clock and busy.
LABEL specifies the string to be displayed when a control is in a
subpanel.
LOCKED
Used with record types of: PANEL, BOX, SUBPANEL, SWITCH and CONTROL.
LOCKED provides the mechanism to prevent a component definition of
identical type, name and parent from overriding (replacing) this
definition. Since the front panel can be defined within multiple
configuration files, it provides the flexibility to override components
found earlier in the search path. Like actions and file types, this
allows the front panel to be customized at several levels.
MONITOR_TYPE
Used with record types of: CONTROL.
Used with control types of: icon and file
MONITOR_TYPE specifies the method of checking the file being monitored,
specified by the keyword FILE_NAME.
NUMBER_OF_ROWS
Used with record types of: SWITCH.
NUMBER_OF_ROWS provides control over the layout of the workspace switch
buttons. The switch buttons are arranged in a row and column layout
with the NUMBER_OF_ROWS keyword defining the number of rows in the
layout. The number of columns is derived from this value and the total
number of switch buttons.
PANEL_GEOMETRY
Used with record types of: PANEL.
PANEL_GEOMETRY specifies a non-default location to position the front
panel when it is created. By default, the front panel is centered along
the bottom of the display.
POSITION_HINTS
Used with record types of: BOX, SWITCH and CONTROL.
POSITION_HINTS specifies the ordering of boxes in the front panel, the
switch and controls in boxes, and controls in subpanels. When two
components have the same value for POSITION_HINTS, the first one read
from the configuration file is placed first.
PUSH_ACTION
Used with record types of: CONTROL.
PUSH_ACTION specifies the function that is invoked when a selection
occurs on the control.
PUSH_ANIMATION
Used with record types of: CONTROL.
Used with all control types except: client.
PUSH_ANIMATION specifies the name of an animation record to be
displayed when a selection occurs on the control. The control must have
a PUSH_ACTION defined for the animation to be used.
PUSH_RECALL
Used with record types of: CONTROL.
Used with control keywords of: CLIENT_NAME.
When PUSH_RECALL is set to True, it specifies that only one process can
be started by the control. If the process is already running, it is
displayed within the current workspace and shuffled to the top of the
window stack. The value for the CLIENT_NAME keyword is used to identify
the process for push recall behavior.
RESOLUTION
Used with record types of: PANEL.
RESOLUTION allows the icon set for the front panel to be forced to a
particular set. By default, the front panel determines the display
resolution at runtime and chooses the high resolution icon set if the
display width is 1024 pixels or wider.
SUBPANEL_UNPOST
Used with record types of: PANEL.
When SUBPANEL_UNPOST is set to True, it causes a subpanel to hide
itself whenever a PUSH_ACTION occurs on one of the subpanel controls.
If the subpanel has been torn off of the front panel, the behavior of
the subpanel is forced to remain posted on PUSH_ACTION.
TITLE
Used with record types of: SUBPANEL.
TITLE specifies the string to be displayed in the title area of the
subpanel.
TYPE
Used with record types of: CONTROL.
A number of different control types are defined by the front panel:
blank
Space-holder control
busy
Busy light
client
A client window
clock
Front panel clock
date
Front panel date
file
References a file on the file system and uses that file's actions and
image
icon
Front panel general control
FILES
The default front panel configuration file is
/usr/dt/appconfig/types/C/dtwm.fp.
Files containing the attributes of dynamically created front panel
components are in the directory $HOME/.dt/types/fp_dynamic.
APPLICATION USAGE
Errors encountered when loading front panel database files are written to
the user's $HOME/.dt/errorlog file.
