NOTE: A label or button element will not disable if the "displayType" design time property for a field is set to HTML_AREA.

NOTE: The disabled "grayed" color is dependent on the LAF set in the Servoy Client Application Preferences. For more information see Preferences: Look And Feel in the Servoy Developer User's Guide.

Type String

Sample

var titleText = myElement.titleText;

var toolTip = myElement.toolTipText;

//sets the tooltip text of the element
myElement.toolTipText = "New tip";
myElement.toolTipText = "<html>This includes <b>bolded text</b> and <font color='blue'>BLUE</font> text as well.";
