Summary
Tag name:
<tr:spacer>
UIComponent class:
org.apache.myfaces.trinidad.component.core.output.CoreSpacer
Component type:
org.apache.myfaces.trinidad.CoreSpacer
spacer occupies a fixed amount of space in a layout, specified by
its width and height attributes. If the width is not specified, but
height specified, a block level HTML element is rendered, thereby
introducing a new line effect. If width is specified, then,
irrespective of the specified value of height, it may not get shorter
than the applicable line-height, in user agents that strictly support
standards mode HTML.
Example(s):
<tr:panelGroupLayout type="horizontal"> <f:facet name="separator"> <tr:spacer width="10" height="1"/> </f:facet> <tr:goLink text="First Link" destination="http://myfaces.apache.org"/> <tr:goLink text="Second Link" destination="http://myfaces.apache.org"/> <tr:goLink text="Third Link" destination="http://myfaces.apache.org"/> </tr:panelGroupLayout>
