Constructor Details

AbstractCheckSelector

public AbstractCheckSelector(String id)

Construct.

Parameters:

id - the component id

Method Details

wantAutomaticUpdate

protected boolean wantAutomaticUpdate()

Returns:

Whether the individual checkboxes should update the state of the Selector. If true, then when a checkbox is clicked, the state of all checkboxes is tested - if all are checked, the selector is checked too. If not, the selector is unchecked.

renderHead

public void renderHead(IHeaderResponse response)

Description copied from class: Component

Render to the web response whatever the component wants to contribute to the head section.

Specified by:

renderHead in interface IHeaderContributor

Overrides:

renderHead in class Component

Parameters:

response - Response object

onComponentTag

protected void onComponentTag(ComponentTag tag)

Description copied from class: Component

Processes the component tag. Overrides of this method most likely should call the super implementation.

Overrides:

onComponentTag in class Component

Parameters:

tag - Tag to modify

getFindCheckboxesFunction

protected abstract CharSequence getFindCheckboxesFunction()

Concrete subclasses must override this to provide a Javascript function that returns the IDs of all checkboxes that should be controlled by this selector.

Returns:

a String containing a Javascript expression that evaluates to a function(!). This function must return an array containing the IDs of all checkbox input elements that this selector should control.
