未收到TVN_SELCHANGING [英] TVN_SELCHANGING not received

问题描述

我有一个WTL81应用程序. CMainFrame有一个子CPaneContainer，有一个子窗口CTreeViewCtrl.问题是CTreeViewCtrl没有收到TVN_SELCHANGING消息.

I have a WTL81 app. CMainFrame has a child CPaneContainer, that has a child window CTreeViewCtrl. The problem is CTreeViewCtrl doesn't receive TVN_SELCHANGING message.

我侦察" CTreeViewCtrl及其父级(CPaneContainer)，并且未收到任何通知代码.

I have "spied" CTreeViewCtrl and his parent (CPaneContainer) and no notification code is received.

CMainFrame是从公共CFrameWindowImpl<CMainFrame>

CMainFrame is implemented from public CFrameWindowImpl<CMainFrame>

CPaneContainer的实现是这样的

CPaneContainer is implemented like this

class PaneContainerReflectNotif : public CPaneContainer 
{
    BEGIN_MSG_MAP(PaneContainerReflectNotif)
        CHAIN_MSG_MAP(CPaneContainer)
        REFLECT_NOTIFICATIONS()
    END_MSG_MAP()
};

树是这样实现的

class MyTreeView : 
    public CWindowImpl<CatalogTreeView, CTreeViewCtrl>,
    public CCustomDraw<CatalogTreeView>,
    public CTheme

   ...

BEGIN_MSG_MAP_EX(MyTreeView )
    MSG_WM_CREATE(OnCreate)
    MSG_WM_DESTROY(OnDestroy)
    REFLECTED_NOTIFY_CODE_HANDLER_EX(NM_DBLCLK, OnDblClick)
    REFLECTED_NOTIFY_CODE_HANDLER_EX(TVN_ITEMEXPANDING, OnItemExpanding)
    REFLECTED_NOTIFY_CODE_HANDLER_EX(TVN_SELCHANGING, OnSelChanged)

OnDblClick-工作正常
OnItemExpanding-工作正常
OnSelChanged-不起作用

OnDblClick - works fine
OnItemExpanding - works fine
OnSelChanged - doesn't work

关于可能是什么问题的任何想法?

any ideas on what could be the problem ?

推荐答案

已解决.我的问题是，树视图是多选择的，并且这种树不会发送TVN_SELCHANGING通知

Solved. My problem was that treeview was multi-selct and that kind of tree doesn't send TVN_SELCHANGING notifications
