我做了一個元件，inherits TCustomControl. 如何讓他可以有 popupmenu 呢? .h class package CMyComponent: TCustomCOntrol { public: TPopupmenu *FPopupmenu; void __fastcall SetPopupMenu(TPopupMenu* value); __published: __property TPopupMenu *PopupMenu = {read = FPopupMenu, write = SetPopupMenu}; } .cpp void __fastcall CMyComponent::SetPopupMenu(TPopupMenu* value) { FPopupmenu = value } //form.cpp CMyComponent *a = new CMyComponent(this); a->PopupMenu = PopupMenu1; 我是這樣寫，可是沒有反應ㄟ

wsxcv123你好： 你好像沒有 class="code"> .h中 ~~ class TMyMemo : public TMemo { __published: private: public: TPopupMenu *MyPopMenu; //定義子元件有一個TPopupMenu void __fastcall SetPopupMenu(TPopupMenu* MenuName); //設定使用此PopupMenu的事件 __fastcall TMyMemo(TComponent* Owner); //新TMemo元件的constructor,必寫 }; .cpp中 ~~ __fastcall TMyMemo::TMyMemo(TComponent* Owner) //TMyMemo的constructor撰寫 : TMemo(Owner) { this->MyPopMenu=new TPopupMenu(this); //在這new這個PopupMenu子元件 } //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) //測試使用 { TMyMemo* m=new TMyMemo(this); //叫出一個TMyMemo物件 m->Parent=this; m->SetPopupMenu(m->MyPopMenu); //設定MyMemo的popupmenu，讓它有popupmenu可用 } //--------------------------------------------------------------------------- void __fastcall TMyMemo::SetPopupMenu(TPopupMenu* MenuName) { TMenuItem* itm=new TMenuItem(this); MenuName->Items->Add(itm); //定義PopupMenu上面要用的MenuItem itm->Caption="Test"; this->PopupMenu=MenuName; //最後還要把MyMemo的PopupMenu屬性指給它才行 } All,精神是這樣的，參著參著!
