C++的Win32，如何將下拉菜單添加到一個Win32對話框

嗨，

這是我第一次發佈quesiton到計算器。

我想添加combobox（在menu.cpp中）到Win32對話框（在fingerspell.cpp中）。我在Win32 編程中不太流利，大多數msdn示例代碼片段在窗口內繪製了一個組合框。儘管Dialogbox在技術上是一個窗口，但我在修改任何窗口示例代碼來處理DialogBox方面還沒有太多進展。我真的很感激一個工作的例子。

代碼的粗略草圖如下。 fingerspell.cpp創建實現WinMain函數，然後調用其他自定義類來繪製此DialogBox。沒有其他窗口控件，如按鈕，文本區域等，被使用。對於fingerspell.cpp

代碼爲menu.cpp

#include "fingerspell.h" 
extern "C" __declspec(dllexport)bool isGloveDriverInstalled(); 
extern "C" __declspec(dllimport)bool initialize(); 

#define RUN(x) if (SUCCEEDED(result)) { result = x; } 

BOOL g_fullscreen = FALSE; 
bool portReady; 

INT_PTR CALLBACK OptionDialogProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam) 
{ 
    switch (uMsg) { 
     case WM_INITDIALOG: 
      if (wParam == IDOK) 
       return TRUE ; 
      else 
       return FALSE ; 
      break; 

     case WM_COMMAND: 
      if (HIWORD(wParam) == BN_CLICKED) { 
       if (LOWORD(wParam) == IDOK) { 
        g_fullscreen = TRUE; 
        EndDialog (hwndDlg, 1) ; 
       } 
       else if (LOWORD(wParam) == ID_WINDOW_OPT) { 
        g_fullscreen = FALSE; 
        EndDialog (hwndDlg, 1) ; 
       } 
       else { 
        EndDialog (hwndDlg, 0) ; 
       } 

       return TRUE ; 
      } 

     default: 
      return FALSE; 
      break ; 
    } 
} 


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) 
{ 
    INT_PTR DispOption = DialogBox (hInstance, MAKEINTRESOURCE(IDD_DISPLAY_OPTIONS), NULL, OptionDialogProc) ; 
    if (DispOption == 0) 
     return 0 ; 

    //srand(GetTickCount()); 

    HRESULT result = S_OK; 

    if (!isGloveDriverInstalled()) 
    { 
     portReady = FALSE; 
     MessageBox(NULL, "The Glove Driver is not istalled ", "Error", MB_OK); 
    } 
    else 
    { 
     if (!initialize()) 
     { 
      portReady = FALSE; 
      MessageBox(NULL, "Error Opening Com Port", "Error", MB_OK); 
     } 
     else 
     { 
      portReady = TRUE; 
     } 
    } 

    RUN(Words ::Create  ("default.txt")); 
    RUN(Window::Create  ()); 
    RUN(Render::Create  ()); 
    RUN(Art ::Create  ()); 
    RUN(Menu ::Create  ()); 
    RUN(Window::MessageLoop()); 
    RUN(Menu ::Destroy ()); 
    RUN(Art ::Destroy ()); 
    RUN(Render::Destroy ()); 
    RUN(Window::Destroy ()); 
    RUN(Words ::Destroy ()); 

    if (FAILED(result)) 
    { 
     MessageBox(GetDesktopWindow(), "Warning - Fail Code Detected", "Fingerspell 2002", MB_ICONWARNING | MB_OK); 
    } 

    return result; 
} 

代碼。文件，即時嘗試添加組合框。

    Render::Reset(); 
    Window::SetProc(Proc); 
    return S_OK; 
} 

HRESULT Menu::Destroy(void) 
{ 
    return S_OK; 
} 

LRESULT CALLBACK Menu::Proc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)

    DWORD i ; 

    const static RECT button_rect[ 8 ] =

        {

         Render::SetOverlay(0, (ART) (ART_MENU_LEARN + i), button_rect[ i ].left, button_rect[ i ].top); 

         break;

       } 
      }

我覺得它比Visual Studio編輯器更好的（即來，只有具備專業）

在Vista或更高版本，使用按鈕控制的簡單BS_SPLITBUTTON風格（WC_BUTTON），然後處理BCN_DROPDOWN到創建你的菜單。

我沒有嘗試這樣做實際的代碼，但是這看起來樣合理：http://www.codereflect.com/2009/02/19/how-to-create-a-drop-down-button-in-windows-vista-7/
