\maketitle


  This reference manual describes the Tk \ident{radar} widget interface. It shows
  how to create and configure a \ident{radar} widget, and how to use the commands
  it provides to create and manipulate items.



\chapter{Widget options}
\concept{options}
  \option{borderwidth}{borderWidth}{BorderWidth}
  \begin{blockindent}
    Specifies the width of the 3d border that should be displayed around the widget
    window. This border does not overlap the active radar display area. The area
    requested from the geometry manager (or the window manager if applicable) is the
    overall area, display area plus borders. This value can be given in any of
    the forms valid for coordinates (See \cident{TkGet\_Pixels}). The default value is 2 pixels.
  \end{blockindent}
  
  \option{backcolor}{backColor}{BackColor}
  \begin{blockindent}
    This the color that will be used to fill the radar window. It is also
    used as a default color for some item attributes of type color. See each
    color attribute for the actual source of the default color. Its default
    value is white.
  \end{blockindent}
  
  \option{cursor}{cursor}{Cursor}
  \begin{blockindent}
    Specifies the cursor to use when the pointer is in the radar window.
    The default value is set to preserve the cursor provided at widget
    creation.
  \end{blockindent}
  
  \option{font}{font}{Font}
  \begin{blockindent}
    The font specified by this option is used as a default font
    for item attributes of type font. Its default value is
    -adobe-helvetica-bold-r-normal--*-120-*-*-*-*-*-*.
  \end{blockindent}
  
  \option{forecolor}{foreColor}{ForeColor}
  \begin{blockindent}
    The color specified by this option is used as a default color
    for many item attributes of type color. See each each color
    attribute for the actual source of the default color. Its
    default value is black.
  \end{blockindent}

  \option{height}{height}{Height}
  \begin{blockindent}
    Specifies the height of the actual radar area (i.e, this dimension
    does not include the border width). This value can be given in any of
    the forms valid for coordinates (See \cident{Tk\_GetPixels}). The default is
    100 pixels.
  \end{blockindent}
  
  \option{mapdistancesymbol}{mapDistanceSymbol}{MapDistanceSymbol}
  \begin{blockindent}
    This option specifies the symbol to be used as a milestone
    along map lines. This option can be given any Tk bitmap which
    can be obtained by \cident{Tk\_GetBitmap}. The spacing between markers is
    10 nautic miles. The default value is AtcSymbol19.
  \end{blockindent}
  
  \option{maptextfont}{mapTextFont}{MapTextFont}
  \begin{blockindent}
    Specifies the font used to draw the texts contained in maps. The
    default is -adobe-helvetica-bold-r-normal--*-120-*-*-*-*-*-*.
  \end{blockindent}
  
  \option{overlapmanager}{overlapManager}{OverlapManager}
  \begin{blockindent}
    This option accepts any form valid for a boolean. It specifies if
    the label overlapping avoidance algorithm should be allowed to
    do its work on the track labels. The default is to enable the avoidance
    algorithm.
  \end{blockindent}
  
  \option{pickaperture}{pickAperture}{PickAperture}
  \begin{blockindent}
    Specifies the size of an area around the pointer that is used to tell
    if the pointer is inside an item. This is useful to lessen the precision
    required when picking graphical elements. This value must be a positive
    integer. It defaults to 1.
  \end{blockindent}

  
  \option{relief}{relief}{Relief}
  \begin{blockindent}
    Specifies the border relief. This option can be given any legal value
    for a relief (See \cident{Tk\_GetRelief} for a description of possible values).
  \end{blockindent}

  
  \option{speedvectorlength}{speedVectorLength}{SpeedVectorLength}
  \begin{blockindent}
    Specifies the duration of track speed vectors. This option is expressed
    using a time unit that should be chosen by the application (often minutes)
    and kept coherent with the unit of the track attribute \attrref{speedvector}
    (often nautic mile / minutes). The default value is 3.
  \end{blockindent}

  
  \option{trackmanagedhistorysize}{trackManagedHistorySize}{TrackManagedHistorySize}
  \begin{blockindent}
    This option accepts only positive integers. It specifies the size of
    the past position list that can be maintained by the track items. See
    also the \optref{trackmanagehistory} option and the \attrref{visiblehistorysize}
    track attribute. The default value is 6.
  \end{blockindent}

  
  \option{trackmanagehistory}{trackManageHistory}{TrackManageHistory}
  \begin{blockindent}
    This option accepts any form valid for a boolean. It specifies if
    the track items should maintain a list of their past positions to be
    displayed as trailing speckles. If this option is turned off and then
    back on, the history list is erased and the collection is resumed at
    the next available position. The number of position collected in the
    history list is specified by the option \optref{trackmanagedhistorysize}.
    When this many positions are collected, the oldest is dropped to make
    room for the new one on a first in first out basis. The number of past
    positions actually displayed if specified for each track by the
    attribute \attrref{visiblehistorysize}.
    The default value is to enable the history collection.
  \end{blockindent}

  
  \option{width}{width}{Width}
  \begin{blockindent}
    Specifies the width of the actual radar area (i.e, this dimension
    does not include the border width). This value can be given in any of
    the forms valid for coordinates (See \cident{Tk\_GetPixels}). The default is
    100 pixels.
  \end{blockindent}

  
\chapter{Item IDs and Tags}
\concept{tagOrId}
Décrire les ids, tags, field tags et part tags. Les deux derniers
n'étant employes que par bind doit-on les décrire ici ou dans la commande ?
Parler de current, all.


\chapter{Coordinates and transformations}

\chapter{Widget commands}

  The available commands are listed in alphabetical order.
  
  The command set for the \ident{radar} widget is much inspired by the \ident{canvas}
  command set. Someone comfortable with the \ident{canvas} should not have much trouble
  using the \ident{radar}'s commands. Eventually, the command set will be a superset
  of the \ident{canvas} command set.

\vspace{.5cm}  
\radarcmd{add}{?type group? ?args? ?option value? ... ?option? value?}
  \begin{blockindent}
    This command is used to create new items in a radar. It can be called with
    no parameters to return the list of all item types currently known by
    the radar. It can also be called with a valid item type as first parameter
    and a group item as second parameter to create a new item of this type in
    the given group. The other arguments vary with the type of item. A detailed
    description of these arguments is given in the sections on the individual item
    types. Following the creation args the command accept any number of
    attributes\ -\ values pairs to configure the newly created item.
    All the configurable item type attributes are valid in this context. The
    command returns the item id.
  \end{blockindent}

\radarcmd{addtag}{tag searchSpec ?arg arg ...?}
  \begin{blockindent}
     This command add the given tag to all items matching the
     search specification. If the tag is already present on some item,
     nothing is done for this item. The command has no effect if no
     items satisfy the given criteria. The command returns en empty
     string. The search specification an the associated arguments can
     take the following forms:
     \begin{description}
     \item{\tt above tagOrId} \\
       Selects the item just above the one given by {\tt tagOrId}. If
       {\tt tagOrId} names more than one item, the topmost of these
       items in the display list will be used. If {\tt tagOrId} does
       not refer to any item then nothing happen.

     \item{\tt all} \\
       Selects all the items in the radar.

     \item{\tt atpoint x y ?halo? ?start?} \\
       Selects the item under or closest to the point {\tt x - y}. If more
       than one item overlaps the point, the top-most is selected. If {\tt halo}
       is given, it defines the size of the point {\tt x - y}. {\tt halo} must
       be a non negative integer. If {\tt start} is specified, it must be
       an item tag or id. If it names a valid item (for a tag, the lowest
       item with the tag is considered), the search starts with the item
       below {\tt start} instead of the first item in the display
       order. If {\tt start} does not name a valid item, it is ignored.

     \item{\tt atpriority priority} \\
       Selects all the items at the given priority.

     \item{\tt below tagOrId} \\
       Selects the item just below the one given by {\tt tagOrId}. If
       {\tt tagOrId} names more than one item, the lowest of these
       items in the display list will be used. If {\tt tagOrId} does
       not refer to any item then nothing happen.

     \item{\tt enclosed xo yo xc yc} \\
       Selects all the items completely enclosed in the rectangle whose
       origin is at {\tt xo - yo} and corner at {\tt xc - yc}. {\tt xc}
       must be no greater than {\tt xo} and {\tt yo} must be no greater
       than {\tt yc}. All coordinates must be integers.

     \item{\tt overlapping xo yo xc yc} \\
       Selects all the items that overlaps or are enclosed in the rectangle
       whose origin is at {\tt xo - yo} and corner at {\tt xc - yc}. {\tt xc}
       must be no greater than {\tt xo} and {\tt yo} must be no greater than
       {\tt yc}. All coordinates must be integers.

     \item{\tt withtag tagOrId} \\
       Selects all the items given by {\tt tagOrId}.

     \item{\tt withtype type} \\
       Selects all the items of type {\tt type}.
     \end{description}
  \end{blockindent}

\radarcmd{anchorxy}{tagOrId anchor}
  \begin{blockindent}
    Returns the (device) coordinate of an item anchor. If no item is
    named by {\tt tagOrId} or if the item doesn't support anchors, an
    error is raised. If more than one item match {\tt tagOrId}, one of
    those is used, the exact one is implementation specific.
  \end{blockindent}
    
\radarcmd{bbox}{tagOrId ?tagOrId ...?}
  \begin{blockindent}
    Returns a list of 4 numbers describing the (device) coordinates of the origin
    and corner of a rectangle bounding all the items named by the {\tt tagOrId}
    arguments. If no items are named by the {\tt tagOrId} or if the matching items
    have an empty bounding box, an empty string is returned.
  \end{blockindent}

\radarcmd{bind}{tagOrId ?sequence? ?command?}
  \begin{blockindent}
    This command associates {\tt command} with the item tag, item id, part tag
    {\tt tagOrId}. If an event sequence matching {\tt sequence}
    occurs for an item, or an item part, the command will be invoked.
    If all parameters are specified a new binding between {\tt sequence} and
    {\tt command} is established, overriding any existing binding for the
    sequence. If the first character of {\tt command} is ``+'', then
    {\tt command} augments the existing binding instead of replacing it.
    In this case the command returns an empty string. If the {\tt command}
    parameter is omitted, the command return the {\tt command} associated
    with {\tt tagOrId} and {\tt sequence} or an error is raised if there
    is no such binding. If only {\tt tagOrId} is specified the command
    returns a list of all the sequences for which there are bindings for
    {\tt tagOrId}.
    
    This widget command is similar to the \ident{bind} command except that
    it operates on \ident{radar} items instead of widgets. Another difference
    with the \ident{bind} command is that only mouse and keyboard related events
    can be specified (such as \ident{Enter}, \ident{Leave}, \ident{ButtonPress},
    \ident{ButtonRelease}, \ident{Motion}, \ident{KeyPress}, \ident{KeyRelease}).
    The \ident{bind} manual page is the most accurate place to look for a
    definition of {\tt sequence} and {\tt command} and for a general understanding
    of how the binding mecanism works.

    The handling of events in the \ident{radar} is done with respect to the
    current item and when applicable the current item part (see
    \conceptref{Item IDs and tags}{tagOrId} for a discussion of the
    \ident{current} tag and the special tags used in bindings). \ident{Enter}
    and \ident{Leave} events are trigerred for an item when it becomes or cease
    to be the current item. Mouse related events are reported with respect to
    the current item. Keyboard related events are reported with respect to the
    focus item (which can be the current item or none).

    It is possible that several bindings match a particular event sequence.
    When this occurs, all matching bindings are triggered. The order of
    invocation is as follow: the binding associated with the tag \ident{all}
    is invoked first, followed by the bindings associated with the item tags
    in order, followed by the binding associated with the item id, followed
    by the binding associated with the item part if relevant.
    If there are more than one binding for a single tag, only the most
    specific is triggered.
    
    If bindings have been registered for the \ident{radar} window using the
    \ident{bind} command, they are invoked in addition to bindings registered
    for the items using this widget command. The bindings for items will be
    invoked before the bindings for the window.
  \end{blockindent}

\radarcmd{cget}{option}
  \begin{blockindent}
    Returns the current value of the widget option given by {\tt option}.
    {\tt option} may be any of the options described in the
    chapter \conceptref{Widget options}{options}.
  \end{blockindent}

\radarcmd{chggroup}{}
  \begin{blockindent}
    Not yet implemented.
  \end{blockindent}

\radarcmd{configure}{?option? ?value? ?option value ...?}
  \begin{blockindent}
    Query or modify the options of the widget. If no {\tt option}
    is given, returns a list describing all the supported options (see the
    chapter \conceptref{Widget options}{options}). If an {\tt option} is
    specified without any {\tt value}, the command returns a list
    describing the named option (this list is identical to the corresponding
    sublist of the value returned if no {\tt option} is given). If some
    {\tt option - value} pairs are given, then the corresponding options
    are changed and the command return an empty string.
  \end{blockindent}

\radarcmd{currentpart}{}
  \begin{blockindent}
    Returns an integer specifying the item part over which the pointer is.
    If the current item doesn't have parts or if the pointer is not over
    an item (no item has the \ident{current} tag) the command return -1.
  \end{blockindent}

\radarcmd{dtag}{tagOrId ?tagToDelete?}
  \begin{blockindent}
    Delete the tag {\tt tagToDelete} from the list of tags associated
    with each item named by {\tt tagOrId}. If an item doesn't have
    the tag then it is leaved unaffected. If {\tt tagToDelete} is
    omitted, {\tt tagOrId} is used instead. The command returns an
    empty string as result.
  \end{blockindent}

\radarcmd{find}{searchCommand ?arg arg ...?}
  \begin{blockindent}
    This command returns the list of all items selected by {\tt searchCommand}
    and the {\tt args}. See the \cmdref{addtag} command for an explanation of
    {\tt searchCommand} and the various {\tt args}. The items are sorted in
    drawing order, topmost first.
  \end{blockindent}

\radarcmd{gettags}{tagOrId}
  \begin{blockindent}
    This command returns the list of all the tags associated with
    the item specified by {\tt tagOrdId}. If more than one item is
    named by {\tt tagOrdId}, then one of these items (selection is
    implementation specific) is used to return the result. If no
    item is named by {\tt tagOrdId}, then the empty list is returned.
  \end{blockindent}

\radarcmd{hasanchors}{tagOrId}
  \begin{blockindent}
    This command returns a boolean telling if the item specified by
    {\tt tagOrdId} supports anchors. If more than one item is named by
    {\tt tagOrdId}, then one of these items (selection is implementation
    specific) is used to return the result. If no items are named by
    {\tt tagOrdId}, an error is raised.
  \end{blockindent}

\radarcmd{hasfields}{tagOrId}
  \begin{blockindent}
    This command returns a boolean telling if the item specified by
    {\tt tagOrdId} supports fields. If more than one item is named by
    {\tt tagOrdId}, then one of these items (selection is implementation
    specific) is used to return the result. If no items are named by
    {\tt tagOrdId}, an error is raised.
  \end{blockindent}

\radarcmd{hasparts}{tagOrId}
  \begin{blockindent}
    This command returns a boolean telling if the item specified by
    {\tt tagOrdId} has parts. If more than one item is named by
    {\tt tagOrdId}, then one of these items (selection is implementation
    specific) is used to return the result. If no items are named by
    {\tt tagOrdId}, an error is raised.
  \end{blockindent}

\radarcmd{hastag}{tagOrId tag}
  \begin{blockindent}
    This command returns a boolean telling if the item specified by
    {\tt tagOrdId} has the specified tag. If more than one item is
    named by {\tt tagOrdId}, then one of these items (selection is
    implementation specific) is used to return the result. If no items
    are named by {\tt tagOrdId}, an error is raised.
  \end{blockindent}

\radarcmd{itemcget}{tagOrId ?field? attr}
  \begin{blockindent}
    To be written
  \end{blockindent}

\radarcmd{itemconfigure}{tagOrId ?field? ?attr? ?value? ?attr value ...?}
  \begin{blockindent}
    To be written
  \end{blockindent}

\radarcmd{lower}{tagOrId ?belowThis?}
  \begin{blockindent}
    Reorder all the items given by {\tt tagOrId} so that they will be
    under the item given by {\tt belowThis}. If {\tt tagOrId} name more
    than one item, their relative order will be preserved. If
    {\tt tagOrId} doesn't name an item, an error is raised. If
    {\tt belowThis} name more than one item, the bottom most them is used.
    If {\tt belowThis} doesn't name an item, an error is raised. If
    {\tt belowThis} is omitted the items are put at the bottom most
    position. The command returns an empty string.
    As a side affect of this command, the \attrref{priority} attribute of
    all the reordered items is ajusted to match the priority of the
    {\tt belowThis} item (or the priority of the bottom most item).
  \end{blockindent}

\radarcmd{raise}{tagOrId ?aboveThis?}
  \begin{blockindent}
    Reorder all the items given by {\tt tagOrId} so that they will be
    above the item given by {\tt aboveThis}. If {\tt tagOrId} name more
    than one item, their relative order will be preserved. If
    {\tt tagOrId} doesn't name an item, an error is raised. If
    {\tt aboveThis} name more than one item, the top most is used.
    If {\tt aboveThis} doesn't name an item, an error is raised. If
    {\tt aboveThis} is omitted the items are put at the top most
    position. The command returns an empty string.
    As a side affect of this command, the \attrref{priority} attribute of
    all the reordered items is ajusted to match the priority of the
    {\tt aboveThis} item (or the priority of the top most item).
  \end{blockindent}

\radarcmd{remove}{tagOrId ?tagOrId ...?}
  \begin{blockindent}
    Delete all the items named by each {\tt tagOrId}. The
    command returns an empty string.
  \end{blockindent}

\radarcmd{rotate}{tagOrId angle ?centerX centerY?}
  \begin{blockindent}
    Add a rotation to the items or the transform described by
    {\tt tagOrId}. If {\tt tagOrId} describe a named transform
    then this transform is used to do the operation. If {\tt tagOrId}
    describe more than one item then all the items are affected by
    the opration. If {\tt tagOrId} describe neither a named transform
    nor an item, an error is raised. The angle is given in radians.
    The optional parameters describe the center of rotation, which
    defaults to the origin.
  \end{blockindent}

\radarcmd{scale}{tagOrId xFactor yFactor}
  \begin{blockindent}
    Add a scale factor to the items or the transform described by
    {\tt tagOrId}. If {\tt tagOrId} describe a named transform
    then this transform is used to do the operation. If {\tt tagOrId}
    describe more than one item then all the items are affected by
    the opration. If {\tt tagOrId} describe neither a named transform
    nor an item, an error is raised. A separate factor is specified for
    X and Y.
  \end{blockindent}

\radarcmd{tapply}{}
  \begin{blockindent}
    To be implemented.
  \end{blockindent}

\radarcmd{tdelete}{tName}
  \begin{blockindent}
    Destroy a named transform. If the given name is not found
    among the named transforms, an error is raised.
  \end{blockindent}

\radarcmd{transform}{?tagOrIdFrom? tagOrIdTo coordList}
\begin{blockindent}
  This command returns a list of coordinates obtained by transforming
  the coordinates given in {\tt coordList} from the coordinate space
  of the transform or item described by {\tt tagOrIdFrom} to the
  coordinate space of the transform or item described by {\tt tagOrIdTo}.
  If {\tt tagOrIdFrom} is omitted it defaults to the device coordinate
  space. If either {\tt tagOrId} describe more than one item, one is
  selected in a system specific way. If either {\tt tagOrId} describe
  neither a transform nor an item, an error is raised.
\end{blockindent}

\radarcmd{translate}{tagOrId xAmount yAmount}
  \begin{blockindent}
    Add a translation to the items or the transform described by
    {\tt tagOrId}. If {\tt tagOrId} describe a named transform
    then this transform is used to do the operation. If {\tt tagOrId}
    describe more than one item then all the items are affected by
    the opration. If {\tt tagOrId} describe neither a named transform
    nor an item, an error is raised. A separate value is specified for
    X and Y.
  \end{blockindent}

\radarcmd{treset}{tagOrId}
  \begin{blockindent}
    Set the named transform or the transform for the items described
    by {\tt tagOrId} to identity. If {\tt tagOrId} describe neither
    a named transform nor an item, an error is raised.
  \end{blockindent}

\radarcmd{trestore}{tagOrId tName}
  \begin{blockindent}
    Set the transform for the items described by {\tt tagOrId} to the
    transform named by {\tt tName}. If {\tt tagOrId} doesn't describe
    any item or if the transform named {\tt tName} doesn't exist, an
    error is raised.
  \end{blockindent}

\radarcmd{tsave}{tagOrId tName}
  \begin{blockindent}
    Create (or reset) a transform associated with the name {\tt tName}
    which has for initial value the transform associated with the item
    {\tt tagOrId}. If {\tt tagOrId} describe more than one item, one is
    selected in a system specific way. If {\tt tagOrId} doesn't describe
    any item, an error is raised. If {\tt tName} already exists, the
    transform is set to the new value. This command is the only way to
    create a named transform.
  \end{blockindent}

\radarcmd{type}{tagOrId}
  \begin{blockindent}
    This command returns the type of the item specified by {\tt tagOrdId}.
    If more than one item is named by {\tt tagOrdId}, then the type of

\attribute{labelformat}{labelFormat}
\begin{blockindent}
  The new format is as follow. Parameters between [] are
  optional and take default values when omitted. The spaces can appear
  between blocks but not inside.
 
        \verb+[WidthxHeight] [field0Spec] [field1Spec] [fieldnSpec]+
 
  Width and Height set the size of the clipping box surrounding
  the label. If it is not specified, there will be no clipping.
  It it is specified alone it is the size of the only displayed
  field (0).
 
  fieldSpec is:
        \verb+sChar fieldWidth sChar fieldHeight [pChar fieldX pChar fieldY]+.
 
  Each field description refers to the field of same index in the field
  array.
  If \verb+sChar+ is \verb+'x'+, the dimension is in pixel. If \verb+sChar+ is \verb+'f'+, the
  dimension is in percentage of the mean width/height of a character (in the
  field font). If \verb+sChar+ is \verb+'i'+, the dimension is in percentage of the size
  of the image in the field. If \verb+sChar+ is \verb+'a'+, the dimension is automatically
  adjusted to match the field's content plus the given value in pixels.
  
  If \verb+pChar+ is \verb-'+'- the position is in pixel (possibly negative). If it is
  \verb+'<'+ the position is the index of the field at the left/top of which the
  current field should be  attached. If it is \verb+'>'+ the position is the index
  of the field at the right/bottom of which the current field should be
  attached. If \verb+pChar+ is \verb+'^'+ the position is the index of the field used to
  align the left/top border (left on left or top on top). If \verb+pChar+ is \verb+'$'+ the %$
  position is the index of the field used to align the right/bottom border
  (right on right or bottom on bottom).
  
  The positional parameters can be omitted if there is only one field.  
\end{blockindent}

\attribute{leaderanchors}{leaderanchors}
\begin{blockindent}
  Describe where to attach the label leader on the label. These are not
  to be confused with the regular rectangular anchors.
  
  The format is: \verb+lChar leftLeaderAnchor [lChar rightLeaderAnchor]+
  
  If \verb+lChar+ is a \verb+'|'+, \verb+leftLeaderAnchor+ and \verb+rightLeaderAnchor+
  are the indices of the fields that serve to anchor the label's leader. More
  specifically the bottom left corner of the left field and the bottom right corner of
  the right field are used as the anchors.
  If \verb+lChar+ is \verb+'%'+, \verb+leftLeaderAnchor+ and \verb+rightLeaderAnchor+
  should be specified as \verb+valxval+, \verb+val+ being a percentage (max 100) of
  the width/height of the label bounding box. If rightLeaderAnchor is not specified
  it defaults to field 0. If rightLeaderField is not specified it defaults to
  leftLeaderAnchor. If neither of them are specified, the center of the label
  is used as an anchor.
