I have Class Based on TPanel - class TBaseButton : public TPanel { protected: virtual void __fastcall WndProc( TMessage &Message ); DYNAMIC void __fastcall MouseDown( TMouseButton Button, TShiftState Shift, int X, int Y ); DYNAMIC void __fastcall MouseMove( TShiftState Shift, int X, int Y ); private: void __fastcall OnMouseEnter( void ); void __fastcall OnMouseLeave( void ); TImage *Image; public: __fastcall TBaseButton( TComponent* Owner ); }; -- -- -- -- -- -- -- -- -- -- -- -- -- I want that the TImage which i have on this Pannel (the Image is part of the Class as you can see) will act just as the Panel itself, meaning that when i click it, it will go to the same MouseDown function of the Panel, and then i move mouse cursor over it will call the 'MouseMove' event of the Panel, and that when i Enter or Leave it's borders it will call the 'WndProc' event ( which is where i call the functions 'OnMouseEnter' and 'OnMouseLeave'. How do i do that? I tried in the TBaseButton Constructor things like - Image->OnMouseDown = MouseDown; and Image->MouseDown = MouseDown; and Image->OnMouseDown = &MouseDown; but i'm keep getting errors for all this lines... Thanks very much. Ramy Back to top Ramy Guest Posted: Tue Jun 22, 2004 11:06 am    Post subject: Re: Need help with new Class Events... Also, what do i have do write in the Class and in the CPP file if i want to create an event for the Image, for example 'OnMouseUp' event?
