想請教各位前輩:
在ScrollBox裡的垂直和水平滾動條,有類似ScrollBar的OnChanged的事件嗎?只要我的滾動條一移動就觸發事件
找了許久仍未找到,請知道的前輩能不吝指教..謝謝...

試試下面的code

<textarea class="cpp" rows="10" cols="60" name="code"> //.h class TForm1 : public TForm { __published: // IDE-managed Components TScrollBox *ScrollBox1; TImage *Image1; void __fastcall FormCreate(TObject *Sender); private: // User declarations TWndMethod OldScrollBoxWndProc; void __fastcall ScrollBoxWndProc(TMessage& Message); public: // User declarations __fastcall TForm1(TComponent* Owner); }; //.cpp //--------------------------------------------------------------------------- void __fastcall TForm1::FormCreate(TObject *Sender) { OldScrollBoxWndProc = ScrollBox1->WindowProc; ScrollBox1->WindowProc = ScrollBoxWndProc; } //--------------------------------------------------------------------------- void __fastcall TForm1::ScrollBoxWndProc(TMessage& Message) { switch (Message.Msg) { case WM_VSCROLL: { //int nScrollCode = (int) HIWORD(Message.WParam); //Form1->Caption = "V:" IntToStr(nScrollCode); //do something } break; case WM_HSCROLL: { //do something } break; } OldScrollBoxWndProc(Message); } </textarea>

  感謝版大的教導可以使用了,謝謝...
