Attribute	Data Type	Default	Description
tooltip	String	none	Set the tooltip of this particular component
jsTooltipEnabled	String	false	Enable js tooltip rendering
tooltipIcon	String	/struts/static/tooltip/tooltip.gif	The url to the tooltip icon
tooltipDelay	String	500	Tooltip shows up after the specified timeout (miliseconds). A behavior similar to that of OS based tooltips.
key	simple	String	The name of the property this input field represents. This will auto populate the name, label, and value

tooltipConfig is deprecated, use individual tooltip configuration attributes instead Every Form UI component (in xhtml / css_xhtml or any other that extends them) can have tooltips assigned to them. The Form component's tooltip related attribute, once defined, will be applied to all form UI components that are created under it unless explicitly overriden by having the Form UI component itself defined with their own tooltip attribute.

In Example 1, the textfield will inherit the tooltipDelay and tooltipIconPath attribte from its containing form. In other words, although it doesn't define a tooltipIconPath attribute, it will have that attribute inherited from its containing form.

In Example 2, the textfield will inherite both the tooltipDelay and tooltipIconPath attribute from its containing form, but the tooltipDelay attribute is overriden at the textfield itself. Hence, the textfield actually will have its tooltipIcon defined as /myImages/myIcon.gif, inherited from its containing form, and tooltipDelay defined as 5000.

Example 3, 4 and 5 show different ways of setting the tooltip configuration attribute.
Example 3: Set tooltip config through the body of the param tag
Example 4: Set tooltip config through the value attribute of the param tag
Example 5: Set tooltip config through the tooltip attributes of the component tag

  <!-- Example 1: --> <s:form tooltipDelay="500" tooltipIconPath="/myImages/myIcon.gif" .... > .... <s:textfield label="Customer Name" tooltip="Enter the customer name" .... /> .... </s:form> <!-- Example 2: --> <s:form tooltipDelay="500" tooltipIconPath="/myImages/myIcon.gif" .... > .... <s:textfield label="Address" tooltip="Enter your address" tooltipDelay="5000" /> .... </s:form> <-- Example 3: --> <s:textfield label="Customer Name" tooltip="One of our customer Details"> <s:param name="tooltipDelay"> 500 </s:param> <s:param name="tooltipIconPath"> /myImages/myIcon.gif </s:param> </s:textfield> <-- Example 4: --> <s:textfield label="Customer Address" tooltip="Enter The Customer Address" > <s:param name="tooltipDelay" value="500" /> </s:textfield> <-- Example 5: --> <s:textfield label="Customer Telephone Number" tooltip="Enter customer Telephone Number" tooltipDelay="500" tooltipIconPath="/myImages/myIcon.gif" />
