getDefaultStateImageUri

public java.lang.String getDefaultStateImageUri(RenderingContext rc,
                                                boolean selected)

Description copied from class: ToggleButtonUI

Parameters:

rc - The RenderingContext to which the button is being rendered.

selected - True if the selected state image is being requested.

Returns:

The URI of the default state image.

ToggleButtonUI.getDefaultStateImageUri(RenderingContext, boolean)

getScriptAction

public java.lang.String getScriptAction(RenderingContext rc)

Description copied from class: AbstractButtonUI

Returns JavaScript code that will be executed when the button is clicked. On plain Buttons, this will normally send input to the server. On ToggleButtons, the selection state will change and input may also be sent to the server if desired by the application.

getScriptAction in class AbstractButtonUI

Parameters:

rc - The RenderingContext being used for the rendering of the button.

getStateId

public Id getStateId()

Description copied from class: ToggleButtonUI

Returns the Id of the controller input field in which the ToggleButton's state is to be stored. In the case where multiple RadioButtons are in a ButtonGroup, the state will be stored in only one field, specified by this method.

The default implementation returns the Id of this peer.

Overrides:

getStateId in class ToggleButtonUI

Returns:

The Id of the controller input field used to store the ToggleButton's state.
