<p>This sample constructs an <a>HTMLInfo</a> that acts as a re-implementation of the default text editor.
|
|
<p>The implementation is contained in the file <a href="TextEditor.js" target="_blank">TextEditor.js</a>
|
|
and exposes <code>window.TextEditor</code>,
|
|
which is used in this file as the value of <code>myDiagram.toolManager.textEditingTool.defaultTextEditor</code>.
|
|
<p>This also adds a text validation predicate, <code>okName</code>, as the <a>TextBlock.textValidation</a> property.
|
|
That predicate makes sure that the new string has at least three characters and contains a vowel.
|
|
<p>You can see additional custom text editors in the <a href="../samples/customTextEditingTool.html">Custom TextEditingTool sample</a>.
