public class DynaRadioButtonList
extends CustomComponent
implements ItemListener, FastComponent, ActionListener, Precreation

Displays a list of radio buttons, with labels, from which the user can select one option.

A list of possible java beans to select from can be set using the setList(List) method. These java beans will be represented on the screen with a label. This label is determined using the setLabelProperty(String) method.

Method Detail

rebind

public void rebind()

Description copied from interface: RebindableComponent

This operation causes the component to reset it's content to that of the domain model.

Specified by:

rebind in interface RebindableComponent

Overrides:

rebind in class CustomComponent

getList

public java.util.List getList()

Gets the list of java beans the user can select from.

setList

public void setList(java.util.List list)

Sets the list of java beans the user can select from.

getLabelProperty

public java.lang.String getLabelProperty()

Gets the property (path) that determines what label is shown for the individual java beans in the list of possible java beans.

setLabelProperty

public void setLabelProperty(java.lang.String labelProperty)

Sets the property (path) that determines what label is shown for the individual java beans in the list of possible java beans.

getDecorator

public Decorator getDecorator()

Gets the Decorator instance that is used to decorate the labels on the radio buttons.

Specified by:
