Summary

Tag Name: <trh:tableLayout>
Java Class: org.apache.myfaces.trinidad.component.html.HtmlTableLayout
Component Type: org.apache.myfaces.trinidad.HtmlTableLayout
A TableLayout is a thin wrapper around the HTML <table> element. It contains a series of row layout elements.

Table Layout

By default, HTML tables treat cell widths more like suggestions rather than requirements; cell content sizes contribute more in determining the size of each column. If you care more for the specified cellFormat widths than content sizes (particularly if your cellFormat widths are percentage-based and your cells have contents that are programmatically-resizable based on the cell width), then you will need to use inlineStyle="table-layout:fixed" to declare that you want your cell widths to be explicitly honored. Refer to the CSS specification for further details on this style property.

Code Example(s)

<trh:tableLayout width="75%"
                 borderWidth="3"
                 cellSpacing="10"
                 halign="center">
  <trh:rowLayout>
    <!-- First Column -->
    <trh:cellFormat valign="bottom" />
    <!-- SecondColumn -->
    </trh:cellFormat>
    <tr:panelGroupLayout layout="horizontal">
      <!-- Third Column -->
      <tr:spacer height="100" width="1"/>
    </tr:panelGroupLayout>
  </trh:rowLayout>
  <trh:rowLayout>
    <tr:panelHeader text="Apache Trinidad Components"/>
    <trh:cellFormat columnSpan="2">
      <tr:panelHeader text="Faces Servlet"/>
    </trh:cellFormat>
  </trh:rowLayout>
</trh:tableLayout>

Supported Client Events for Client Behaviors

  • click (default)
  • dblclick
  • keydown
  • keypress
  • keyup
  • mousedown
  • mousemove
  • mouseout
  • mouseover
  • mouseup

Events

Type Phases Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application,
Apply Request Values		 Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

Attributes

Name Type Supports EL? Description
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding org.apache.myfaces.trinidad.component.html.HtmlTableLayout Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
borderWidth int Yes the border width around each cell.
cellPadding int Yes the spacing within cells.
cellSpacing int Yes the spacing between cells.
halign String Yes Valid Values: right, start, left, end, center

the horizontal alignment of the table. The acceptable values are "center", "left", "right", "start", and "end".
id String No the identifier for the component. Every component may be named by a component identifier that must conform to the following rules:
  • They must start with a letter (as defined by the Character.isLetter() method) or underscore ( _ ).
  • Subsequent characters must be letters (as defined by the Character.isLetter() method), digits as defined by the Character.isDigit() method, dashes ( - ), or underscores ( _ ). To minimize the size of responses generated by JavaServer Faces, it is recommended that component identifiers be as short as possible. If a component has been given an identifier, it must be unique in the namespace of the closest ancestor to that component that is a NamingContainer (if any).
inlineStyle String Yes the inline CSS style for this element
onclick String Yes an onclick Javascript handler.
ondblclick String Yes an ondblclick Javascript handler.
onkeydown String Yes an onkeydown Javascript handler.
onkeypress String Yes an onkeypress Javascript handler.
onkeyup String Yes an onkeyup Javascript handler.
onmousedown String Yes an onmousedown Javascript handler.
onmousemove String Yes an onmousemove Javascript handler.
onmouseout String Yes an onmouseout Javascript handler.
onmouseover String Yes an onmouseover Javascript handler.
onmouseup String Yes an onmouseup Javascript handler.
partialTriggers String[] Yes the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too.
rendered boolean Yes Default Value: true

whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
shortDesc String Yes the short description of the bean. This text is commonly used by user agents to display tooltip help text.
styleClass String Yes the CSS style class of the bean.
summary String Yes The summary of the table's purpose and structure for user agents rendering to non-visual media. This attribute must be set if this element is being used to implement a data table (instead of a layout table).
width String Yes the preferred total width of the layout.
