控件没有mouseup函数。应该怎么弄。
我在使用Scintilla做个简单的源码编辑器。Scintilla本身没有像tpanel一样的mouseup可以调用。我是想右键Scintilla文本框弹出一个TPopupMenu,

Scintilla 控件代码如下：

C/C++ code

class TScEdit : public TWinControl{protected:    virtual void __fastcall CreateParams(Controls::TCreateParams &Params)    {        TWinControl::CreateParams(Params);        CreateSubClass(Params, "Scintilla");    }    virtual void __fastcall WndProc(Messages::TMessage &Message)    {          TWinControl::WndProc(Message);        if(Message.Msg == WM_GETDLGCODE) //让窗体接受方向键和TAB键            Message.Result = DLGC_WANTALLKEYS|DLGC_WANTARROWS|DLGC_WANTTAB;            if (Message.Msg == WM_RBUTTONUP)              {   POINT   P;             GetCursorPos(&P);                  TPopupMenu *PopupMenux=new TPopupMenu(this);           //    PopupMenu1->Popup(P.x, P.y);              }    }public:    __fastcall TScEdit(Classes::TComponent* AOwner)        :TWinControl(AOwner){;}    sptr_t SendEditor(unsigned int iMessage, uptr_t wParam = 0, sptr_t lParam = 0)    {        return SendMessage(Handle, iMessage, wParam, lParam);    }};

if (Message.Msg == WM_RBUTTONUP)
{ POINT P;
GetCursorPos(&P);
TPopupMenu *PopupMenux=new TPopupMenu(this);
// PopupMenu1->Popup(P.x, P.y);

}
这个可以产生一个PopupMenu,但是我希望能够直接调用窗口中建好的PopupMenu1,请问怎么操作？？？。

class TForm1 : public TForm
{
__published:// IDE-managed Components
TPopupMenu *PopupMenu1;
TMenuItem *a;
TMenuItem *b;
TMenuItem *c;

[解决办法]
那这里就不用新建了，你懂得。
TPopupMenu *PopupMenux=new TPopupMenu(this);

C/C++ code

TPopupMenu *PopupMenux=Screen->ActiveForm->PopupMenu;if(PopupMenux ){...}
