Multi-line text input control.
This is a simple wrapper around the HTML textarea control.
Note that many browsers do not cope well with long lines of unbroken text (i.e., greater than 4K characters with no white space.)
The default css class used for the main element within this control. This is overridden by subclasses.
Number of columns in the textarea control. property rows as %ZEN.Datatype.integer(MINVAL=0);
Number of rows in the textarea control. property spellcheck as %ZEN.Datatype.boolean [ InitialExpression = 1 ];
If true, this control has spellcheck enabled. Assuming this is an HTML5 browser implementation. IE9 does not support this.
Subclasses implement this in order to render the static HTML contents of a component.
Override default implementation.
Set the value of a named property.
