NAME

       TextComp,  TextView,  TextGraphic,  PSText  -  multiline  text  component  subject,  view,
       structured graphic, and PostScript external representation

SYNOPSIS

       #include <Unidraw/Components/text.h>

DESCRIPTION

       TextComp is a GraphicComp that defines a piece of multiline text.  It uses  a  TextGraphic
       (a  subclass  of  Label) to store its graphical attributes.  TextView is a GraphicView for
       displaying  the  text.   PSText  is  a  PostScriptView  that  externalizes  the  subject's
       information in PostScript form.

TEXTCOMP PUBLIC OPERATIONS

       TextComp(TextGraphic* = nil)
              The  constructor  takes  an optional TextGraphic that defines the attributes of the
              text.

       virtual void Interpret(Command*)
       virtual void Uninterpret(Command*)
              TextComp  redefines  (Un)interpret  to  ignore  BrushCmd  and  PatternCmd  and   to
              (un)interpret FontCmd.

       TextGraphic* GetText()
              Return  the  TextGraphic  that defines the text component's attributes.  GetText is
              simply a more specific form of the GetGraphic operation.

TEXTVIEW PUBLIC OPERATIONS

       TextView(TextComp* = nil)
              Create an TextView, optionally supplying the subject.

       virtual void Interpret(Command*)
              TextView interprets AlignToGridCmd to align its lower-left to the grid.

       virtual Manipulator* CreateManipulator(
          Viewer*, Event&, Transformer*, Tool*
       )

       virtual void InterpretManipulator(Manipulator*)
              TextView  redefines  its  response  to   manipulation   with   a   GraphicCompTool.
              GraphicCompTool  will let the user position and type out the component's text using
              TextManip. Positioning of the text will be influenced by gravity, if any.  TextView
              also  defines  a  response  to  the ReshapeTool to let the user edit the text.  The
              subject  is  actually  replaced  (via  ReplaceCmd)  with  a  new  TextComp  subject
              positioned at the original TextComp's location but reflecting the edited text.

       TextComp* GetTextComp()
              Return the subject.

TEXTVIEW PROTECTED OPERATIONS

       virtual boolean TextChanged()
              Return whether the text in the subject is any different from that in the view.

TEXTGRAPHIC PUBLIC OPERATIONS

       TextGraphic(const char*, int h, Graphic* = nil)
       TextGraphic(const char*, Graphic*)
              Create  a  TextGraphic,  specifying  its  text,  optional  inter-line  spacing, and
              optional graphic from which to obtain  default  graphics  attributes.   TextGraphic
              stores a copy of the given string (behavior it inherits from Label).  If inter-line
              spacing is not specified, then lines will be separated to reflect the  font  height
              reported by PSFont.

       void SetLineHeight(int)
       int GetLineHeight()
              Explicitly set and get the inter-line spacing.

       virtual boolean operator == (TextGraphic&)
       virtual boolean operator != (TextGraphic&)
              Report  whether the given graphic contains or does not contain an identical copy of
              the text in this

PSTEXT PUBLIC OPERATIONS

       PSText(TextComp* = nil)
              Construct a PostScript external representation of the given subject, if any.

PSTEXT PROTECTED OPERATIONS

       const char* Filter(const char* string, int length)
              Filter excapes embedded control or other special characters that would cause syntax
              errors in the PostScript output.
