The Owner window may change any values of received FVCNDATA_NMHDR structure in order to raise needed action. For example it may substitute FVCA_INVALIDATE to FVCA_CUSTOMDRAW event to force painting on self offscreen context. It can be: FVCA_CUSTOMDRAW - in this case you need to provide valid HDC to draw on and valid RECT of smiley FVCA_INVALIDATE - to invalidate specified rect of window FVCA_NONE - skip any action. But be aware - animation will be stopped till next repainting of smiley. FVCA_SENDVIEWCHANGE - to notify richedit ole about object changed. Be aware Richedit will fully reconstruct itself Another point is moment of received smiley rect - it is only valid if FVCA_DRAW is initially set, and it is PROBABLY valid if FVCA_INVALIDATE is set. And it most probably invalid in case of FVCA_SENDVIEWCHANGE. The smiley position is relative last full paint HDC. Usually it is relative to top-left corner of host richedit (NOT it client area) in windows coordinates. */ // Type of Event one of #define FVCN_PREFIRE 1 #define FVCN_POSTFIRE 2 // Action of event are going to be done #define FVCA_NONE 0 #define FVCA_DRAW 1 // do not modify hdc in case of _DRAW, Use _CUSTOMDRAW #define FVCA_CUSTOMDRAW 2 #define FVCA_INVALIDATE 3 #define FVCA_SENDVIEWCHANGE 4 #define FVCA_SKIPDRAW 5 // Extended NMHDR structure for WM_NOTIFY typedef struct { //NMHDR structure HWND hwndFrom; // Window of smiley host UINT idFrom; // ignored UINT code; // NM_FIREVIEWCHANGE size_t cbSize; BYTE bEvent; // FVCN_ value - pre- or post- painting BYTE bAction; // FVCA_ keys HDC hDC; // Canvas to draw on RECT rcRect; // Valid/should be in case of FVCA_DRAW COLORREF clrBackground; // color to fill background if fTransparent is not set BOOL fTransparent; // if need to fill back color LPARAM lParam; // used by host window PreFire and PostFire event } FVCNDATA_NMHDR; // Code of WM_NOTIFY message (code) #define NM_FIREVIEWCHANGE NM_FIRST+1; #endif #endif // m_anismiley_h__
