ColumnAttribute Component

The ColumnAttribute component is used as child of a GridPanel (or BridgePanel) component in order to select which columns should appear. By default GridPanel instances will show a selection of the attributes of the objects used in the data source. With the ColumnAttribute component the exact number (and which) of attributes can be selected.

XML Definition:

<xvw:columnAttribute 
   dataField='name' 
   ....

   label='Nome'
 >

</xvw:columnAttribute>

Property - Renderer:

The renderer property allows the developer to custom render a given column attribute. If one would want to display the value of the column in italic the following should be done.

XML Definition

<xvw:columnAttribute dataField='myFields' renderer='#{viewBean.myRenderer}'>

Java Bean Code

public GridColumnRenderer getMyRenderer() {    
             return new GridColumnRenderer() {
                 public String render( GridPanel grid, DataRecordConnector record, DataFieldConnector field ) {
                     String oValue = field.getValue();
                     return "<i>" + oValue + "</i>";
                 } 
              }
}

Notes: A DataRecordConnector represents the line form the current Grid and the DataFieldConnector represents the field from the current line.
