<xwt>
+ A single-line or multi-line edit widget. Only handles text with one font and one color, and is capable of line or word wrapping.
- A text edit box.
+ TRAPS:
- multiline : boolean -- if true, lines will be broken at newline characters
- editable : boolean -- if false, the text cannot be changed, although it can be copied
+ - multiline : boolean -- If true, edit widget will expand vertically to handle newlines.
+ - editable : boolean -- If true, the user can insert, paste and delete text.
+ - disabled : boolean -- If false, user can select text and copy to clipboard.
+ - wrap : string -- Either "none", "line" or "word", specifing the form of text wrap to use.
+ - selection : string -- Returns the currently selected text. Putting values does nothing, see FUNCTIONS, selectText().
+ - text : string -- Represents the complete text of this edit widget. Can be read and written to.
+ - limit : int -- A limit imposed on the total number of characters in the edit widget. 0 > limit means no limit.
+ - textcolor : color -- Color of the text.
+ - selectcolor : color -- Background Color of the currently selected text.
+ - selecttextcolor : color -- Color of the currently selected text.
+ - textChanged : boolean -- Set to true when the contents of the edit widget has changed.

+ FUNCTIONS:
- <template textcolor="black" orient="vertical" vpad="2" editable="true" multiline="false" text="" cursor="text">
+ If you wish to directly manipulate the contents of the edit widget consider using these functions to speed up manipulation.
+ All line references are based on hard carrige returns. You do not have to consider soft line wraps when making calculations.
- // Structural Stuff //////////////////////////////////////////////////////////////////////
+ - insertText(line, index, text) - Insert text at given char index on given line.
+ - deleteText(startline, startindex, endline, endindex) - Delete text in given range.
+ - selectText(startline, startindex, endline, endindex) - Select text in given range.
+ - clearSelection() - Deselect any current selection.
+ - deleteSelection() - Delete the text within the current selection range.
+ - moveCursor(line, index) - Move the cursor to the given position.
- // Cursor1 is the cursor -- when there is no selection, its width is
- // 1, and its height is the height of one line. When the user selects
- // a one-line region, Cursor1 is expanded to cover that region (but
- // placed behind the text on the z-axis). When the user selects more
- // than one line, Cursor1 covers the background of the first line of
- // the selection, Cursor3 covers the last line, and the intermediate
- // lines get their color set to "blue".
- var curs = $curs; // the main cursor
- var curs2 = $curs2; // the "backup" cursor for multiline selections
- var numcursors = 2; // the number of non-textline children of this box
- var master = 0;
+ THEME NOTES:
- <box text="" align="topleft"/>
- <box id="curs" absolute="true" textcolor="white" color="blue" width="1" y="0" x="1" invisible="true"/>
- <box id="curs2" absolute="true" textcolor="white" color="blue" width="1" y="0" x="1" invisible="true"/>
+ - Most of the implementation of this widget does not need to be considered in a theme, however a particular theme may wish
+ to override _KeyPressed to add extra theme features (eg. Monopoly word skip on Ctrl+Left Arrow).

+ - In the implementation of the edit widget, there are two systems (loosely similar to model-view) used to reference text.
+
+ The first, referencing each 'hard' line (from one carrige return to the next) as a box inside $content
+ with the string property fulltext representing the contents of the row is used as the text model.
+ Text is inserted, removed and read using the $content[cl].fulltext properties.
- // the x-coordinate of the end of the selection, measured in _pixels_
- __px2 = function() {
- if (cy2 > numchildren || thisbox[cy2].text == null) return 0;
- return xwt.textwidth(font, thisbox[cy2].text.substring(0, cx2));
- }
+ The second is the on screen reprsentation of the text. Each $content[cl] box can have any number of children ( must be > 0)
+ called 'soft' lines. These softlines are created/managed at the discretion of the $content[cl]._fulltext trap. This means
+ different wrapping systems can be completely isolated inside the _fulltext trap. The only components of the system that
+ work outside of the model are cursor and selection positioning. The functions that manipulate these features have public
+ functions that mimic the 'model' style functions, but also have private internal functions that use cy and px variables
+ to reference location.
- // on the r-th row, this will determine how many characters are to the left of a
- // point b pixels from the left edge of the edit Algorithm is a binary search,
- // making educated guesses based on the average width of a character on that line.
- getboundary = function(r, b) {
+ - A reference to each cursor is stored in the static area, and a global thread is used to call the _blink trap on cursors.
- if (o >= b) return 0;
- var s = thisbox[r].text;
+ - Boxes are also stored in a static array when unused, however the effective value of this is questionable, and should be
+ properly benchmarked.
- var left = 0; // the left boundary of the search region, in characters

- var end = xwt.textwidth(font, s);
- if (b >= end) return right; // short circuit if we're off the end
+ - If moving the cursor to a different cl line after changing the structure of the edit box, be sure to call the funciton from
+ a background thread. Otherwise, the position x,y values will be wrong.
