Detailed Description

A graphic attribute selection suite message. This message will be broadcast whenever selection attributes affecting graphic attributes are changed.

Member Enumeration Documentation

enum IGraphicAttrMessage::MessageType

CSB messages for selection and selection attribute changes.

Enumerator
kMsg_DefinitionChanged	kMsg_DefinitionChanged indicates that the whole or parts of definition changed in one or more ways (nil, one or more attr classes). The class list below can be empty, i.e. ClassID count is 0, then the whole definition changes. If class list is > 0, then only those attributes included are affected.
kSwapStrokeAndFillMsg	kSwapStrokeAndFillMsg indicates the fill and stroke have been swapped. The class list will be nil.
kGraphicStateChangedChangeMsg	kGraphicStateChangedChangeMsg indicates the graphic state object is changing. The class list will be nil.
kMsg_SelectionChanged	kMsg_SelectionChanged indicates a message broadcast from cache to suites. Client code should ignore.
kMsg_SelectionAttrChanged	kMsg_SelectionChanged indicates a message broadcast from cache to suites. Client code should ignore.
kMsg_ProxyTypeChanged	kMsg_SelectionChanged indicates a message broadcast from cache to suites. Client code should ignore.
kMsg_AttrsEnableStateChanged	kMsg_SelectionChanged indicates a message broadcast from cache to suites. Client code should ignore.

Member Function Documentation

virtual MessageType IGraphicAttrMessage::GetMessageType ( void  ) const

pure virtual

Returns the message type.

virtual bool16 IGraphicAttrMessage::IsClassAffected ( const ClassID &  classID ) const

pure virtual

Returns whether or not the specified attribute class ID is affected.

Parameters

classID

specifies the interested attribute class ID.

Returns

true if class ID is in the list.

virtual bool16 IGraphicAttrMessage::NeedClearAllBlocks ( void  ) const

pure virtual
