%kText 'Text Object Menuform'
% This MatLab function was automatically generated by a converter (KhorosToMatLab) from the Khoros Text.pane file
%
% Parameters: 
% Integer: textLeftMargin 'Left Margin ', default: 0: 'left margin'
% Integer: TextLabel.labelCursorPos 'Insert Position', default: 0: 'cursor insert position'
% InputFile: textFilename 'Text File', required: 'text file'
% String: textString 'Text String', default: ' ': 'string'
%
% Example: kText(textFilename, {'textLeftMargin',0;'TextLabel.labelCursorPos',0;'textFilename','';'textString',' '})
%
% Khoros helpfile follows below:
% 
% .begin tagged
% 
% .item "The Text GUI Object"
% The Khoros text object may be single-line or multi-line.  It may display
% read-only text, or allow the editing of read-write text. The source for default
% text may be specified directly from within the application (hard-coded) or may
% be contained in a file. The text object supports normal cut and paste
% operations.  It offers a number of key bindings.  Word and line wrapping are
% also supported.
% 
% 
% .item "Text Edit Type"
% Text objects may display text that is read only or read/write.
% Regardless of whether the text is read only or read/write,
% a cursor will appear.  This is so that the user may use the text object's key
% bindings to scroll through text that may not all fit within the text window,
% since automatic addition of vertical and horizontal scrollbars to the text
% object is not yet supported.  Any attempt to edit text in a read-only text
% object will ring the bell.
% 
% .item "Text Wrap Type"
% When the text lines of a multi-line text object exceed the width of the text
% window, text wrapping may be done.  Text wrapping dictates that text lines
% are to be automatically broken in an attempt to get all lines within the width
% of the text window.  Since single-line text objects only allow a single line
% of text, text wrapping applies to multi-line text objects only.  For multi-line
% text, the text object supports three wrapping modes:
% .begin tagged
% .item "No Wrap"
% No text wrapping is done
% .item "Word Wrap"
% The text object will wrap the text at the last word that will fit within the
% width of the text window.  If a single word is wider than the text object,
% that word will still extend past the right hand side of the window; the user
% will be required to use key bindings to see the end of the word.
% .item "Wrap Line"
% The text object will wrap text at the last character that will fit within
% the width of the text window.
% .end tagged
% 
% .item "Left Margin"
% Number of pixels that are to make up the left margin of the text window.
% 
% .item "Multiline Text"
% 
% Text objects may be used to edit and/or display a single line of text or
% multiple lines of text.  Functionality of multi-line text objects is the same
% as that of single-line text objects, except for the following:
% .begin itemize
% .item
% If text containing a line feed is pasted to a multi-line text object,
% the line feed is retained; however, in a single-line text object,
% a line feed is replaced with a space (both types of text objects replace
% unprintable characters with a space).
% .item
% With a single-line text widget, the application may install a callback that
% will be fired when the user enters <return>.  By definition, no such callback
% may be installed on a multi-line text widget, as <return> in the text of a
% multi-line text widget must be used to indicate line feed.
% .item
% Multi-line text objects may be of any height; single-line text objects will
% always be 1 character in height.
% .item
% Multi-line text objects may do text wrapping if directed to do so by the
% application; by definition, single-line text objects do not allow text wrapping.
% .end itemize
% 
% .item "Insert Position"
% This integer specifies the location of the cursor, in characters.  For example,
% if the insert position is 50, that implies that the cursor is at character 50
% of the text.
% 
% .item "Text File"
% File containing the text to be displayed by the text widget. 
% Note that this is mutually 
% exclusive with 'Text String'; use one or the other, not both.
% 
% .item "Text String"
% The string to be displayed by the text widget. Note that this is mutually 
% exclusive with 'Text File'; use one or the other, not both.
