public class UISelectList
extends javax.faces.component.UIInput
implements javax.faces.component.NamingContainer

The SelectList component displays a graphical list of items, each with a label and icon image. The list has three selection modes; single select (radio), multi-select (checkbox) and active selection mode (child action components). The value for the component is collection of UIListItem objects or a UIListItems instance. For passive single and multi-select modes, the selected value(s) can be retrieved from the component. For active selection mode, appropriate child components such as Command buttons or Action Links will be rendered for each item in the list, data-binding to the specified 'var' variable should be used to bind required params. It is then up to the developer to retrieve the selected item param from the actionListener of the appropriate child component.

public UISelectList()

Default constructor

Method Detail

getFamily

public java.lang.String getFamily()

Overrides:

getFamily in class javax.faces.component.UIInput

See Also:

UIComponent.getFamily()

restoreState

public void restoreState(javax.faces.context.FacesContext context,
                java.lang.Object state)

Specified by:

restoreState in interface javax.faces.component.StateHolder

Overrides:

restoreState in class javax.faces.component.UIInput

See Also:

StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)

saveState

public java.lang.Object saveState(javax.faces.context.FacesContext context)

Specified by:

saveState in interface javax.faces.component.StateHolder

Overrides:

saveState in class javax.faces.component.UIInput

See Also:

StateHolder.saveState(javax.faces.context.FacesContext)

getClientId

public java.lang.String getClientId(javax.faces.context.FacesContext context)

Overrides:

getClientId in class javax.faces.component.UIComponentBase

Returns:

the client Id for this naming container component - based on the current row context. This allows a single component rendered multiple times in a list to dynamically base their ID on the current row - so that the 'correct' component is decoded and event is queued with the current row value.

processDecodes

public void processDecodes(javax.faces.context.FacesContext context)

Override the processing of child component decodes - we set the current row context so any events queued by child components wrapped in FacesEventWrapper have current row value.

Overrides:

processDecodes in class javax.faces.component.UIInput

queueEvent

public void queueEvent(javax.faces.event.FacesEvent event)

Override event queueing from child components - wrap and add current row value

Overrides:

queueEvent in class javax.faces.component.UIComponentBase

broadcast

public void broadcast(javax.faces.event.FacesEvent event)
               throws javax.faces.event.AbortProcessingException

Override event broadcasting to look for event wrappers to set the current row context correctly for components that have been rendered multiple times in the list.

Overrides:

broadcast in class javax.faces.component.UIInput

Throws:

javax.faces.event.AbortProcessingException

decode

public void decode(javax.faces.context.FacesContext context)

Overrides:

decode in class javax.faces.component.UIInput

See Also:

UIComponentBase.decode(javax.faces.context.FacesContext)

encodeChildren

public void encodeChildren(javax.faces.context.FacesContext context)
                    throws java.io.IOException

Overrides:

encodeChildren in class javax.faces.component.UIComponentBase

Throws:

java.io.IOException

See Also:

UIComponentBase.encodeChildren(javax.faces.context.FacesContext)

getRendersChildren

public boolean getRendersChildren()

Overrides:

getRendersChildren in class javax.faces.component.UIComponentBase

See Also:

UIComponentBase.getRendersChildren()

encodeBegin

public void encodeBegin(javax.faces.context.FacesContext context)
                 throws java.io.IOException

Overrides:

encodeBegin in class javax.faces.component.UIComponentBase

Throws:

java.io.IOException

See Also:

UIComponentBase.encodeBegin(javax.faces.context.FacesContext)

getRowIndex

public int getRowIndex()

Returns:

current row index

setRowIndex

public void setRowIndex(int rowIndex)

Set the transient current row index. Setting this value causes all child components to have their ID values reset - so that cached clientID values are regenerated when next requested.

Parameters:

rowIndex -

isMultiSelect

public boolean isMultiSelect()

Get the multi-select rendering flag

Returns:

true for multi-select rendering, false otherwise

setMultiSelect

public void setMultiSelect(boolean multiSelect)

isActiveSelect

public boolean isActiveSelect()

Get the active selection mode flag

Returns:

true for active selection mode, false otherwise

setActiveSelect

public void setActiveSelect(boolean activeSelect)

Set true for active selection mode, false otherwise

Parameters:

activeSelect - True for active selection

getEscapeItemLabel

public boolean getEscapeItemLabel()

Get the escape item label flag

Returns:

true if the items label should be escaped, false otherwise

setEscapeItemLabel

public void setEscapeItemLabel(boolean escapeItemLabel)

Set true to escape the items label, false otherwise

Parameters:

escapeItemLabel - true to escape the items label

getEscapeItemDescription

public boolean getEscapeItemDescription()

Get the escape item description flag

Returns:

true if the items description should be escaped, false otherwise

setEscapeItemDescription

public void setEscapeItemDescription(boolean escapeItemDescription)
