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

Every Form UI component (in xhtml / css_xhtml or any others that extends of them) could have tooltip assigned to a them. The Form component's tooltip related attribute once defined will be applicable to all form UI component that is created under it unless explicitly overriden by having the Form UI component itself defined that tooltip attribute.

In Example 1, the textfield will inherit the tooltipDelay adn tooltipIcon attribte from its containing form. In other words, although it doesn't defined a tooltipAboveMousePointer attribute, it will have that attributes inherited from its containing form.

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

Example 3, 4 and 5 shows different way of setting the tooltipConfig attribute.
Example 3:Set tooltip config through body of param tag
Example 4:Set tooltip config through value attribute of param tag
Example 5:Set tooltip config through tooltipConfig attribute of component tag

 

 <!-- Example 1: -->
 <s:form
          tooltipConfig="#{'tooltipDelay':'500',
                           'tooltipIcon='/myImages/myIcon.gif'}" .... >
   ....
     <s:textfield label="Customer Name" tooltip="Enter the customer name" .... />
   ....
 </s:form>

 <!-- Example 2: -->
 <s:form
         tooltipConfig="#{'tooltipDelay':'500',
                          'tooltipIcon':'/myImages/myIcon.gif'}" ... >
   ....
     <s:textfield label="Address"
          tooltip="Enter your address"
          tooltipConfig="#{'tooltipDelay':'5000'}" />
   ....
 </s:form>


 <-- Example 3: -->
 <s:textfield
        label="Customer Name"
        tooltip="One of our customer Details'">
        <s:param name="tooltipConfig">
             tooltipDelay = 500 |
             tooltipIcon = /myImages/myIcon.gif
        </s:param>
 </s:textfield>


 <-- Example 4: -->
 <s:textfield
          label="Customer Address"
          tooltip="Enter The Customer Address" >
          <s:param
              name="tooltipConfig"
              value="#{'tooltipDelay':'500',
                       'tooltipIcon':'/myImages/myIcon.gif'}" />
 </s:textfield>


 <-- Example 5: -->
 <s:textfield
          label="Customer Telephone Number"
          tooltip="Enter customer Telephone Number"
          tooltipConfig="#{'tooltipDelay':'500',
                           'tooltipIcon':'/myImages/myIcon.gif'}" />
