如何解决C ++ Win32，如何向Win32对话框中添加下拉菜单
|| C ++ Win32，如何向Win32对话框添加下拉菜单 你好 这是我第一次将问题发布到stackoverflow。 我试图将组合框（在menu.cpp中）添加到Win32对话框（在fingerpell.cpp中）。我不太会Win32 编程和大多数msdn示例片段在窗口内绘制一个组合框。即使Dialogbox在技术上 一个窗口，但是在修改任何窗口示例代码以处理DialogBox方面我没有什么进展。我非常感谢一个可行的例子。 该代码的大致示意图如下。 fingerpell.cpp创建实现WinMain函数，然后调用 其他自定义类在此DialogBox中绘制。没有使用其他窗口控件，如按钮，文本区域等。 fingerpell.cpp的代码是#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 ;
}
}

我认为它比Visual Studio编辑器（仅专业提供）要好
,在Vista或更高版本上，使用简单的BS_SPLITBUTTON样式的按钮控件（WC_BUTTON），然后处理BCN_DROPDOWN来创建菜单。
我尚未尝试过此实际代码，但此示例看起来很合理：http：//www.codereflect.com/2009/02/19/how-to-create-a-drop-down-button-in-windows- vista-7 /
