Replace the text with "newText" starting at position "start"
for a length of "replaceLength".
<p>
Implementors have to notify the TextChangeListeners that were added
using <code>addTextChangeListener</code> before and after the content
is changed. A <code>TextChangingEvent</code> has to be sent to the
textChanging method before the content is changed and a
<code>TextChangedEvent</code> has to be sent to the textChanged method
after the content has changed.
The text change that occurs after the <code>TextChangingEvent</code>
has been sent has to be consistent with the data provided in the
<code>TextChangingEvent</code>.
This data will be cached by the widget and will be used when the
<code>TextChangedEvent</code> is received.
<p>
The <code>TextChangingEvent</code> should be set as follows:
<ul>
<li>event.start = start of the replaced text
<li>event.newText = text that is going to be inserted or empty String
if no text will be inserted
<li>event.replaceCharCount = length of text that is going to be replaced
<li>event.newCharCount = length of text that is going to be inserted
<li>event.replaceLineCount = number of lines that are going to be replaced
<li>event.newLineCount = number of new lines that are going to be inserted
</ul>
<b>NOTE:</b> newLineCount is the number of inserted lines and replaceLineCount
is the number of deleted lines based on the change that occurs visually.
For example:
<ul>
<li>(replaceText, newText) is> (replaceLineCount, newLineCount)
<li>("", "\n") is> (0, 1)
<li>("\n\n", "a") is> (2, 0)
<li>("a", "\n\n") is> (0, 2)
<li>("\n", "") is> (1, 0)
</ul>
</p>
@param start start offset of text to replace, none of the offsets include
delimiters of preceding lines, offset 0 is the first character of the
document
@param replaceLength length of text to replace
@param text text to replace
