繼承TButton元件並覆寫WndProc虛擬函式....卻異常??? 連點擊Button外面的區域都會被KButton處理???    //---------------------------------------------------------------------------    #ifndef KButtonH #define KButtonH //--------------------------------------------------------------------------- #include  #include #include #include //--------------------------------------------------------------------------- class PACKAGE KButton : public TButton { private: protected: // virtual void __fastcall WndProc(Messages::TMessage &Message); public: __fastcall KButton(TComponent* Owner); __published: }; //--------------------------------------------------------------------------- #endif //--------------------------------------------------------------------------- #include #pragma hdrstop #include "KButton.h" #pragma package(smart_init) //--------------------------------------------------------------------------- // ValidCtrCheck is used to assure that the components created do not have // any pure virtual functions. // static inline void ValidCtrCheck(KButton *) { new KButton(NULL); } //--------------------------------------------------------------------------- __fastcall KButton::KButton(TComponent* Owner) : TButton(Owner) { } //--------------------------------------------------------------------------- namespace Kbutton { void __fastcall PACKAGE Register() { TComponentClass classes[1] = {__classid(KButton)}; RegisterComponents("Samples", classes, 0); } } //--------------------------------------------------------------------------- void __fastcall KButton::WndProc(Messages::TMessage &Message) { switch(Message.Msg){ case WM_LBUTTONDOWN: ShowMessage(Message.WParamHi); ShowMessage("Done by KButton"); break; } TButton::WndProc(Message); }

問題已解決囉~~~
