Constructor Detail

AbstractBuilder

protected AbstractBuilder(FormLayout layout,
                          Container container)

Constructs an AbstractBuilde for the given FormLayout and layout container.

Parameters:

layout - the FormLayout to use

container - the layout container

Throws:

NullPointerException - if layout or container is null

Method Detail

getComponentFactoryDefault

public static ComponentFactory getComponentFactoryDefault()

Returns the factory that is used as default for new builder' as they are created. This default itself is lazily initialize as the DefaultComponentFactory.

Returns:

the factory that is used as default for new builder instances

setComponentFactoryDefault

public static void setComponentFactoryDefault(ComponentFactory factory)

Sets the global default that is used to initialize the per-instanc component factory.

Parameters:

factory - the factory to be used for all new builder instance that do not override the default

getContainer

public final Container getContainer()

Returns the container used to build the form.

Returns:

the layout container

getLayout

public final FormLayout getLayout()

Returns the FormLayout instance used to build this form.

Returns:

the FormLayout

getColumnCount

public final int getColumnCount()

Returns the number of columns in the form.

Returns:

the number of columns

getRowCount

public final int getRowCount()

Returns the number of rows in the form.

Returns:

the number of rows

getComponentFactory

public final ComponentFactory getComponentFactory()

Returns this builder's component factory. If no factor has been set before, it is lazily initialized from the globa default as returned by getComponentFactoryDefault().

Returns:

the component factory

setComponentFactory(ComponentFactory)

setComponentFactory

public final void setComponentFactory(ComponentFactory newFactory)

Sets a new component factory for this builder overriding the default as provided b getComponentFactoryDefault().

Parameters:

newFactory - the component factory to be used for this builder

See Also:

getComponentFactory()

createComponentFactory

protected ComponentFactory createComponentFactory()

Invoked when the per-instance component factory is lazily initialized This implementation returns the global default factory.

setComponentFactoryDefault(ComponentFactory).

Returns:

the factory used during the lazy initialization o the per-instance component factory
