In theory, we could have provided CanvasHelper 40 and CanvasBase as a single template, but that would duplicate 41 a lot of code now residing in CanvasHelper only. 42 43 This template basically interposes itself between the full 44 interface you implement (i.e. not restricted to XCanvas. The 45 problem with UNO partial interface implementation actually is, 46 that you cannot do it the plain way, since deriving from a 47 common base subclass always introduces the whole set of pure 48 virtuals, that your baseclass helper just overrided) and your 49 implementation class. You then only have to implement the 50 functionality <em>besides</em> XCanvas. 51 52 <pre> 53 Example: 54 typedef ::cppu::WeakComponentImplHelper4< ::com::sun::star::rendering::XSpriteCanvas, 55 ::com::sun::star::lang::XInitialization, 56 ::com::sun::star::lang::XServiceInfo, 57 ::com::sun::star::lang::XServiceName > CanvasBase_Base; 58 typedef ::canvas::internal::CanvasBase< CanvasBase_Base, CanvasHelper > ExampleCanvas_Base; 59 60 class ExampleCanvas : public ExampleCanvas_Base, 61 public SpriteSurface, 62 public RepaintTarget 63 { 64 }; 65 </pre> 66 67 @tpl Base 68 Base class to use, most probably one of the 69 WeakComponentImplHelperN templates with the appropriate 70 interfaces. At least XCanvas should be among them (why else 71 would you use this template, then?). Base class must have an 72 Base( const Mutex& ) constructor (like the 73 WeakComponentImplHelperN templates have). As the very least, 74 the base class must be derived from uno::XInterface, as some 75 error reporting mechanisms rely on that. 76 77 @tpl CanvasHelper 78 Canvas helper implementation for the backend in question. This 79 object will be held as a member of this template class, and 80 basically gets forwarded all XCanvas API calls. Furthermore, 81 every time the canvas API semantically changes the content of 82 the canvas, CanvasHelper::modifying() will get called 83 (<em>before</em> the actual modification takes place). 84 85 @tpl Mutex 86 Lock strategy to use. Defaults to using the 87 OBaseMutex-provided lock. Every time one of the methods is 88 entered, an object of type Mutex is created with m_aMutex as 89 the sole parameter, and destroyed again when the method scope 90 is left. 91 92 @tpl UnambiguousBase 93 Optional unambiguous base class for XInterface of Base. It's 94 sometimes necessary to specify this parameter, e.g. if Base 95 derives from multiple UNO interface (were each provides its 96 own version of XInterface, making the conversion ambiguous) 97 */ 98 template< class Base, 99 class CanvasHelper, 100 class Mutex=::osl::MutexGuard, 101 class UnambiguousBase=::com::sun::star::uno::XInterface > class CanvasBase : 102 public Base 103 { 104 public: 105 typedef Base BaseType;
