template<class DrawableClass >
Component* DrawableTypeHandler< DrawableClass >::addNewComponentFromState ( const ValueTree state,
Component parent 
)
inlinevirtual

This method must create a new component from the given state, add it to the specified parent component (which may be null), and return it.

The ValueTree will have been pre-checked to make sure that its type matches the type that this handler supports.

There's no need to set the new Component's ID to match that of the state - the builder will take care of that itself.

Implements ComponentBuilder::TypeHandler.

template<class DrawableClass >
void DrawableTypeHandler< DrawableClass >::updateComponentFromState ( Component component,
const ValueTree state 
)
inlinevirtual

This method must update an existing component from a new ValueTree state.

A component that has been created with addNewComponentFromState() may need to be updated if the ValueTree changes, so this method is used to do that. Your implementation must do whatever's necessary to update the component from the new state provided.

The ValueTree will have been pre-checked to make sure that its type matches the type that this handler supports, and the component will have been created by this type's addNewComponentFromState() method.

Implements ComponentBuilder::TypeHandler.
