It's distinct from the old Web Address attribute, which was a type of UserAttribute. It stores three member variables: m_url A WebAddress object: The URL to fetch when the object to which the attribute is applied is clicked on m_fBounding Whether the clickable area of the object to which the attribute is applied is the bounding box or the actual shape of the object m_pcFrame (Optional) The name of a frame into which to fetch the URL It also stores the following rectangle: m_rectClickableInRendering This member variable is an oddity and it works as follows. When this WebAddressAttribute is contained in an AttrWebAddress in the Camelot tree, then the clickable rectangle of the Web Address Attribute is easily obtained from the parent of the AttrWebAddress in the tree. But when this WebAddressAttribute is set into a RenderRegion, there is no way of finding out the clickable rectangle of the Web Address attribute. But at the same time the WebAddressAttribute *must* know its clickable rectangle. So, this is what happens. When the AttrWebAddress is called to render the WebAddressAttribute, it does the following: a. Makes a copy of the WebAddressAttribute b. Finds out the clickable rectangle c. Stores the clickable rectangle in the WebAddressAttribute d. Sets the WebAddressAttribute into the RenderRegion. The moral of the story is: to find the clickable rectangle when the attribute is stored in the tree, use AttrWebAddress::GetClickableRectangle. Don't call AttrWebAddress::GetClickableRectangleInRendering. ********************************************************************************************/ class WebAddressAttribute : public AttributeValue { CC_DECLARE_DYNCREATE(WebAddressAttribute) //Constructors and initialiser public: WebAddressAttribute(); WebAddressAttribute(WebAddress url, BOOL fBounding=FALSE, TCHAR* pcFrame=NULL); WebAddressAttribute(TCHAR* pcURL, BOOL fBounding=FALSE, TCHAR* pcFrame=NULL); static BOOL Init(); //Destructor, copy constructor and assignment operator public: ~WebAddressAttribute(); WebAddressAttribute(const WebAddressAttribute& waaCopy); WebAddressAttribute& operator=(const WebAddressAttribute& waaCopy); //Operations public: virtual void Render(RenderRegion* pRegion, BOOL Temp = FALSE); virtual void Restore(RenderRegion* pRegion, BOOL Temp); virtual void SimpleCopy(AttributeValue *); virtual NodeAttribute *MakeNode(); BOOL IsDifferent(AttributeValue *pAttr); virtual BOOL Blend(BlendAttrParam* pBlendParam); //Access functions public: void SetClickableRectangleInRendering(DocRect rectNew) { m_rectClickableInRendering=rectNew; } DocRect GetClickableRectangleInRendering() { return m_rectClickableInRendering; } BOOL HasURL() { return (!m_url.IsEmpty()); } BOOL UseBoundingRectangle() { return m_fBounding; } //Toolkit functions public: static void CopyString(TCHAR** ppcCopyTo, const TCHAR* pcCopyFrom); static BOOL AreStringsEqual(TCHAR* pcFirst, TCHAR* pcSecond); //Member variables.

FALSE if the user must deliberately apply this attribute to an object every time he wants to use it. Purpose: The attribute manager calls this function before making an attribute current. There are some attributes - like this WebAddress attribute I'm about to put in - that the user probably won't want to become current. For example, if a user puts a HotLink on an object and happens to have the Give Other Objects Most Recent Attributes option on, all his new objects are going to have HotLinks. That's not good. So those attributes will override this function and return FALSE. ********************************************************************************************/ /******************************************************************************************** > BOOL WebAddressAttribute::HasURL() Author: Graham_Walmsley (Xara Group Ltd) Created: 16/4/97 Returns: TRUE if this WebAddressAttribute has a non-empty URL FALSE if this WebAddressAttribute has an empty URL Purpose: The definitive test to find whether this attribute contains a link to a Web Address.
