Tomahawk Tags |
|
|
Tomahawk tags are collection of standard
components with extended functionality and
many more extra set of components with rich
set of functionality.
1-Tomahawk inputTextHelp tag
This tag creates an input text box but it has
extra ability to select or removing the text
displayed. This text is used to help the user
and is set by “helpText” attribute. The capability
of disappearing or selecting the text is provided by “selectText” attribute of the tag. This tag
has additional feature of displaying value only,
not the widget of the box. This component also
has ability to be visible or not visible according
to the role of the user. In the same way, it also
has the ability to be enabled or disabled
according to the user role. Normally the naming
system of JSF renders the id for the component
with some additional text, typically with id of
the form, as prefix. But this component has an
attribute forceId, which forces the component
to render the same id mentioned in the id attribute.

<head>
<meta http-equiv=”Content-Type”
content=”text/html; charset=iso-8859-1">
<title>t:inputTextHelp example</title>
<style type=”text/css”>
<!—
body{
background-color:#fff2f2;
margin-top:30;
}
.inputstyle{
background-color:#99CCFF;
}

</style>
</head> |

<body ><center>
<t:inputTextHelp id=”ith1" value=””
helpText=”Hello....”
style=”color:#0033CC; font-weight:bold”
styleClass=”inputstyle” title=”inputTextHelp
example 1" /><p>
<t:inputTextHelp id=”ith2" value=””
helpText=”How are you?” selectText=”true”
style=”color:#0033CC; font-weight:bold”
styleClass=”inputstyle” title=”inputTextHelp
example 2" />
</center></body>
</html>
</f:view>
Rendered Output:
This is the output of the page. In this Hello....
and How are you? texts are the texts specified
in the helpText attribute of the tag.
If we take focus on the first component then
text in the component disappears while in the
other whole text is selected because of setting the selectText attribute to true in the
second component. |
