有时您可能想要显示上下文菜单。也就是说，如果用户右键单击而不是（左）单击，则可能需要显示特定菜单。许多MFC控件都没有自己提供这个功能;你必须在父控件上应用动作。



1.启动Microsoft Visual C ++ MFC应用程序命名为ControlContext

2.创建它作为没有AboutBox的对话框

3.在控件上设置对话框标题为上下文相关菜单

4.添加一个按钮对话框。将其ID更改为IDC_SUBMIT_BTN及其提交的标题

5.在对话框中添加一个复选框。将其ID更改为IDC_APPROVED_CHK，其标题更改为已批准：....（等等）

对于控件的上下文菜单，基于对话框和框架的应用程序之间没有区别。要将上下文菜单添加到列表控件，请使用资源编辑器创建菜单，然后添加 ON_WM_CONTEXTMENU（） / OnContextMenu（）处理程序到你的列表控件类：

  void  CMyListCtrl :: OnContextMenu（CWnd * pWnd， CPoint点）
 {
 CMenu菜单; 
 VERIFY（menu.LoadMenu（IDR_MYLIST_POPUP_MENU））; 
 CMenu * pSub = menu.GetSubMenu（ 0 ）; 
  //  必要时修改菜单项（例如灰色项目） 
  int  nCmd = pSub-> TrackPopupMenuEx（
 TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_VERPOSANIMATION | TPM_RETURNCMD | TPM_NONOTIFY，
 point.x，point.y，AfxGetMainWnd （）， 空值）; 
  if （nCmd）
 SendMessage（WM_COMMAND，nCmd）; 
} 

请注意，使用 AfxGetMainWnd（）需要指定指向主对话框窗口的指针在 InitInstance（）中的 CWinApp 成员变量 m_pMainWnd 。

Take a look at this step-by-step explanation: http://www.functionx.com/visualc/howto/contextmenu.htm[^]


Sometimes you may want to display a context menu. That is, if the user right-clicks, instead of a (left) click, you may want to display a particular menu. Many MFC controls don''t provide this functionality on their own; you would have to apply the action on the parent control.

1.Start Microsoft Visual C++ MFC Application named ControlContext
2.Create it as Dialog Box without the AboutBox
3.Set the Dialog Title to Context-Sensitive Menu on Controls
4.Add a button to dialog box. Change its ID to IDC_SUBMIT_BTN and its Caption to Submit
5.Add a check box to the dialog box. Change its ID to IDC_APPROVED_CHK and its Caption to Approved: .... (and so long)

There is no difference between dialog and frame based applications regarding context menus of controls. To add a context menu to a list control, create the menu using the resource editor and add the ON_WM_CONTEXTMENU() / OnContextMenu() handler to your list control class:

void CMyListCtrl::OnContextMenu(CWnd* pWnd, CPoint point)
{
    CMenu menu;
    VERIFY(menu.LoadMenu(IDR_MYLIST_POPUP_MENU));
    CMenu *pSub = menu.GetSubMenu(0);
    // Modify menu items here if necessary (e.g. gray out items)
    int nCmd = pSub->TrackPopupMenuEx(
        TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_VERPOSANIMATION | TPM_RETURNCMD | TPM_NONOTIFY,
        point.x, point.y, AfxGetMainWnd(), NULL);
    if (nCmd)
        SendMessage(WM_COMMAND, nCmd);
}

Note that using AfxGetMainWnd() requires that the pointer to your main dialog window is assigned to the CWinApp member variable m_pMainWnd in InitInstance().
