Field Detail

view

protected V view

The object that is being initialised.

controller

protected Field controller

The controller associated with the view.

Constructor Detail

ViewInitialiser

public ViewInitialiser(V view)

Create a new instance for the specified view.

Parameters:

view - The view to use.

Method Detail

init

public void init()
          throws BindingException

Initialise all the components declared in view that may be automatically initialised.

Throws:

BindingException - If errors are encountered while initialising the components.

initButton

protected void initButton(String name,
                          Field field)
                   throws Throwable

Initialise a Button component along with its style and action listener.

Parameters:

name - The name of the field in view that is to be initialised.

field - The field in the view that is to be initialised.

Throws:

Throwable - If errors are encountered while initialising the button.

initLabel

protected void initLabel(String name,
                         Field field)
                  throws Throwable

Create and configure a Label component for associating with the specified field. If the label component is marked as mandatory, then the Default.Bold.Label style name is assigned, otherwise the behaviour of Utilities.createLabel( String, String ) is maintained.

Note: This method depends upon naming convention. It is expected that the label field is named with a Label suffix to the component the label is associated with. This convention is used to fetch localised properties based on the name of the associated component and not the label itself. Following this convention also enables annotation only the associated component and not the label also.

Parameters:

name - The name of the field.

field - The field corresponding to the name parameter in view.

Throws:

Throwable - Propogates any exceptions encountered up the chain.

initSelectField

protected void initSelectField(String name,

Initialise a ListBox component.

Parameters:

name - The name of the field in view that is to be initialised.

field - The field in the view that is to be initialised.

Throws:

Throwable - If errors are encountered while initialising the listBox field.
