com.sun.rave.web.ui.renderer.CheckboxGroupRenderer
| CheckboxGroupRenderer | | public class CheckboxGroupRenderer extends SelectorGroupRenderer (Code) | | The CheckboxGroupRenderer renders a CheckboxGroup
component as set of checkboxes. The CheckboxGroupRenderer
creates an instance of Checkbox for each
Option instance in the Array, Map, or
Collection returned by the CheckboxGroup
getItems() method and renders them. It also creates
a Label component and renders it as the label for the group.
Zero or more checkboxes may be selected.
The value of the CheckboxGroup will determine
which checkboxes shall be initially selected and subsequetly hold
the current selections.
The checkboxes are rendered as a single column or some number of
rows and columns. The rows and columns are rendered as a table as
defined by the
com.sun.rave.web.ui.renderer.RowColumnRenderer superclass.
The elements
that make up the checkbox occupy a cell in the table.
The style class selector for the group elements is identified by a java
constants defined in the
com.sun.rave.web.ui.theme.ThemeStyles class.
- CHECKBOX_GROUP for the TABLE element.
- CHECKBOX_GROUP_CAPTION for the TD element containing the group label
- CHECKBOX_GROUP_LABEL for the LABEL element used as the CAPTION
- CHECKBOX_GROUP_LABEL_DISABLED for the LABEL used as the CAPTION if the
group is disabled
- CHECKBOX_GROUP_ROW_EVEN for even TR elements
- CHECKBOX_GROUP_ROW_ODD for odd TR elements
- CHECKBOX_GROUP_CELL_EVEN for even TD elements
- CHECKBOX_GROUP_CELL_ODD for odd TD elements
- CHECKBOX for the INPUT element
- CHECKBOX_DISABLED for the INPUT element for disabled checkbox
- CHECKBOX_LABEL for a LABEL element of a checkbox
- CHECKBOX_LABEL_DISABLED for a LABEL element of a disabled checkbox
- CHECKBOX_IMAGE for an IMG element of a checkbox
- CHECKBOX_IMAGE_DISABLED for an IMG element of a disabled checkbox
The name property of each checkbox is the component id of the
CheckboxGroup instance. The id of a Checkbox
component is cbgrpid_N where cbgrpid is the id of the
CheckboxGroup instance and _N is the nth checkbox.
The CheckboxGroup is decoded by identifying the
CheckboxGroup instance component id which is
returned as a request parameter. It represents the name attribute
of the selected checkbox's <input> element. The values of the
identified request parameter are assigned as the submitted value of the
CheckboxGroup component.
If the items property of the CheckboxGroup is null or
zero length, no output is produced.
