>	class ThumbMessage : public Msg

	Author:		Richard_Millican (Xara Group Ltd) <camelotdev@xara.com>
	Created:	27/3/95
	Purpose:	This message is sent to inform the system of important global thumbnail events.
				Currently the only such event is CACHESIZECHANGED, sent whenever the thumbnail
				cache wants its size changing.

	Notes:		The IMPLEMENT_DYNAMIC can be found in winoil\thumb.cpp
	SeeAlso:
	Documentation:
	
*********************************************************************************************/

class ThumbMessage : public Msg
{
	CC_DECLARE_DYNAMIC(ThumbMessage)

public:
	// thumb messages are sent on these events.
	enum ThumbState
	{
		CACHESIZECHANGED,
		KILLCACHE
	};
	
	ThumbState		State;				// The state, as defined above
	INT32				NewSize;			// The new size of the thumbnail caches
	SGLibType		Type;				// The lib type we want this message to apply to

	// Constructor for CacheSizeChanged
	ThumbMessage(ThumbState TheState, INT32 Size)
				: State(TheState), NewSize(Size), Type(SGLib_Blank)
		{ /* empty */ }

	// Constructor for KillCache
	ThumbMessage(ThumbState TheState, SGLibType LibType)
				: State(TheState), NewSize(0), Type(LibType)
		{ /* empty */ }
