How do I add a context menu in a list box in MFC? I don't see any WM_CONTEXTMENU handler in list box's properties. Any ideas?

编辑:我遵循了本教程 MFC列表控件:如何在列表控件中使用上下文菜单?.教程说要从CListBox派生我自己的类，但是现在如何将派生类的列表框添加到对话框中?

I followed this tutorial MFC List Control: How to use a context menu in a list control?. The tutorial says to derive my own class from CListBox which I did, but now how do I add list box of my derived class to the dialog?

推荐答案

在父类中放置一个 OnContextMenu 处理程序.然后添加一个弹出菜单

Put an OnContextMenu handler in the parent class. Then add a popup menu

编辑要添加 OnContextMenu 处理程序，请将事件处理程序添加到PARENT窗口(即不是列表类).通过资源编辑器最容易做到这一点.转到属性页面，然后转到消息部分.然后为 WM_CONTEXTMENU 添加一个功能.

Edit To add the OnContextMenu handler, add an event handler to the PARENT window (ie not the list class). This is most easily done through the resource editor. Go to the properties page then go to the messages section. Then add a function for WM_CONTEXTMENU.

void CYourDialog::OnContextMenu(CWnd* pWnd, CPoint point)
{
    CListCtrl* pList = (CListCtrl*)GetDlgItem( ID_YOUR_LIST );

    if ( (CWnd*)pList == pWnd )
    {
        CMenu menu;
        // Create your menu items.

        int retVal  = menu.TrackPopupMenu( TPM_LEFTALIGN | TPM_TOPALIGN | TPM_NONOTIFY | TPM_RETURNCMD, point.x, point.y, this );
        
        // Handle your returns here.
    }
}
