You get a different structure, but the idea is the same.

Then handle NM_RCLICK instead, as I described.

Alternatively, you can use CTreeCtrl::HitTest to get the item under the mouse, but that's more work.

Well, that headers for a list view aren't non-client area - that's like the borders and title bars of your applications.

If you right click (I assume right?), then you get a NM_RCLICK notification. When a list view sends it, you also get a pointer to a NMITEMACTIVATE structure. Looking at that structure, you have a iSubItem member - which is the column number.

Try it, and see for yourself. What if gives you when you click on a header, I don't know.

NM_CLICK gives you the same information on a left click - but it would be a bit unusual for a left click to bring up a menu.

Hope that helps,

Iain.

It certainly wouldn't be the most unusual thing ever seen on this forum...

how to EXPAND or COLLAPSE a CTreeCtrl item?(TVS_SINGLEEXPAND cannot)

hi,
i want to EXPAND/COLLAPSE an COLLAPSE/EXPAND item when i single-click an item。
and the TVS_SINGLEEXPAND style causes the item being selected to expand and the item being unselected to collapse,but i still want the unselected to keep the old state.

now, i map the NM_CLICK:

<br />
void CTreeControlDlg::OnClickTree1(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
    TRACE("OnClickTree1!\n");<br />
    <br />
    HTREEITEM hItem = m_treeCtrl.GetSelectedItem();<br />
    if ( (hItem != NULL) && m_treeCtrl.ItemHasChildren(hItem))<br />
    {<br />
         ... // but i donot how to do now...<br />
    }<br />
    *pResult = 0;<br />
}<br />

thank u very much!!!

    HTREEITEM   hItem   =   m_treeCtrl.HitTest(pt);
//     HTREEITEM hItem = m_treeCtrl.GetSelectedItem();
    if ( (hItem != NULL) && m_treeCtrl.ItemHasChildren(hItem))
    {    
        static BOOL bExpand = FALSE; // problem: when change to another COLLAPSE item, it will 
                                     // still do the Expand(hItem, TVE_COLLAPSE) code, but not
                                     // do the Expand(hItem, TVE_EXPAND) code.how can i change the
                                     // code? thank u!
        if (bExpand)
        {
            m_treeCtrl.Expand(hItem, TVE_COLLAPSE);
            bExpand = FALSE;

If I'm understanding what you want to do, you can't use that static BOOL bExpand;.

Instead, you need to determine the current state of the item you clicked on. Use CTreeCtrl::GetItemState[^] to determine if the hTreeItem is currently expanded or not, and then act based on that result.

As you've found out, using a static BOOL is a terrible idea. You've found the fatal flaw for yourself.

You can use this to find its current state:

BOOL bExpanded = m_treeCtrl.GetItemState (hItem, TVIS_EXPANDED) == TVIS_EXPANDED;

To check the, erm, expanded state of the given item.

But why are you doing this yourself? This is something the tree can do perfectly well for itself. Just tick the has buttons style, and away you go.

I hope that helps,

Iain.

yes,my codes belows now. but i found another question now.it is:

for example the tree is:
--root1
  --subitem1
  --subitem2
--root2
  --subitem3

when the focus is on the root1 item,and now i change the focus from root1 to root2, the root2 item doesnot collapse at once, and i hit the item root2 again,it then collapse.and now, can i change the codes below to avoid it?
thank u!

void CTreeControlDlg::OnClickTree1(NMHDR* pNMHDR, LRESULT* pResult) 
{
    TRACE("OnClickTree1!\n");
 
    CPoint   pt;   
    GetCursorPos(&pt);   
    m_treeCtrl.ScreenToClient(&pt);   
    
    HTREEITEM   hItem   =   m_treeCtrl.HitTest(pt);
    if ( (hItem != NULL) && m_treeCtrl.ItemHasChildren(hItem))
    {   
        UINT nState = m_treeCtrl.GetItemState(hItem, TVIS_EXPANDED);
        if (nState & TVIS_EXPANDED)
        {
            m_treeCtrl.Expand(hItem, TVE_COLLAPSE);
        }
        else
        {
            m_treeCtrl.Expand(hItem, TVE_EXPAND);        
        }
    }

Hi all,

I am working with Visual Studio .Net 2005. I have created new Smart Device Project with MFC smart Device application. I have selected SDK application option. It should display the inbuilt menu, but the application is not displaying the menu. How to enable menu. please help.

There is also a mobile devices forum which may have people better skilled to help you. In this case, I think cross posting can be forgiven.

I do remember only having two top level menu items on my menu when I created an application for Windows Mobile 5 - each of which appeared in the bottom two corners, and popped up when I pressed a button on the actual device.

Maybe it sulks if you have too many?
