NAME

TextComp, TextView, TextGraphic, PSText - multiline text component subject, view, struc‐ tured 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 informa‐ tion 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. Graphic‐ CompTool will let the user position and type out the component's text using TextMa‐ nip. 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.
