JSF show icon without Button

Question

Hi guys I want to show the icons without buttons but it doesn\'t work. I get the following message: no Mime-Type was Found. The two icons are default icons from Primefaces.<

Answer 1

If you want just a clickable image that trigger an action in the backing bean I suggest wrapping a graphic image in a h:commandLink.

<h:commandLink rendered="#{!task.IS_SEEN}" value="" action="#{YourBean.myAction}">
    <h:graphicImage  value="your-image-here"/>
</h:commandLink>

If you want easy to use, nice, vectorial icons I suggest you to check Font Awesome http://fontawesome.io/icons/ as well.

To use Font Awesome just include the following line in your <h:head>:

<link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css" rel="stylesheet"></link>

Then you can easily put the icons inside commandLinks in this simple way:

<h:commandLink rendered="#{!task.IS_SEEN}" value="" action="#{YourBean.myAction}">
    <i class="fa fa-envelope"></i>
</h:commandLink>

Answer 2

those are in fact CSS classes that point to a sprite file, so technically they are not icons.

try using:

<h:panelGroup styleClass="ui-icon-mail-closed" rendered="#{!task.IS_SEEN}" />

and if there's a need style it accordingly with padding.

Answer 3

Also you need specify css class ui-icon like this:

<h:panelGroup styleClass="ui-icon ui-icon-mail-closed" />
