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

       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.

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

#include<Unidraw/Components/text.h>

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

       virtualvoidInterpret(Command*)virtualvoidUninterpret(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.

TextGraphic(constchar*,inth,Graphic*=nil)TextGraphic(constchar*,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.

       voidSetLineHeight(int)intGetLineHeight()
              Explicitly set and get the inter-line spacing.

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

virtualbooleanTextChanged()
              Return whether the text in the subject is any different from that in the view.

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

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

       virtualManipulator*CreateManipulator(Viewer*,Event&,Transformer*,Tool*)virtualvoidInterpretManipulator(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.
