CTreeCtrl right mouse click handling :(

[Lost User]

I've faced with some odd problem in my code. I have CTreeView in my app and want to display popup menu when I'd made right mouse click at some tree element. In my NM_RCLICK handler I cast pNMHDR to pointer to NMTREEVIEW structure as usuall I had done with CListCtrl - NMLISTVIEW. But after all of that when I tried to use values in ptDrag member I've get garbage only. Thanks for any help:confused:

afx_msg void OnRclickTree1(NMHDR* pNMHDR, LRESULT* pResult); ON_NOTIFY(NM_RCLICK, ID_XML_TREE, OnRclickTree1) void C3DTabViewBar::OnRclickTree1(NMHDR* pNMHDR, LRESULT* pResult) { UNREFERENCED_PARAMETER(pNMHDR); // TODO: Add your control notification handler code here TRACE(_T("OnRclickTree1\n")); HTREEITEM hItem = m_treeClass.GetSelectedItem(); if (hItem != NULL) { CCMGTreeData* pData = reinterpret_cast(m_treeClass.GetItemData(hItem)); switch (pData->GetType()) { case CCMGTreeData::REFERENCES: DoPopupMenu(IDR_REFERENCES); break; case CCMGTreeData::SCHEMAS: DoPopupMenu(IDR_SCHEMAS); break; } } *pResult = 0; } void C3DTabViewBar::DoPopupMenu(UINT nMenuID) { CMenu popMenu; popMenu.LoadMenu(nMenuID); CPoint posMouse; GetCursorPos(&posMouse); UINT uiDisable = MF_BYCOMMAND|MF_GRAYED; UINT uiEnable = MF_BYCOMMAND|MF_ENABLED; if (nMenuID == IDR_REFERENCES) { popMenu.EnableMenuItem(ID_REFERENCES_ADD_MESSAGE_DEFENITION, IsRefernceIncluded(CCMGTreeData::MESSAGE_DEFENITION) ? uiDisable: uiEnable); popMenu.EnableMenuItem(ID_REFERENCES_ADD_CLASS_OF_SERVICE, IsRefernceIncluded(CCMGTreeData::CLASS_OF_SERVICE) ? uiDisable: uiEnable); popMenu.EnableMenuItem(ID_REFERENCES_ADD_BALANCE_DEFENITION, IsRefernceIncluded(CCMGTreeData::BALANCE_DEFENITION) ? uiDisable: uiEnable); } popMenu.GetSubMenu(0)->TrackPopupMenu(0, posMouse.x, posMouse.y, this); } Good luck! :)

Thanks a lot. It really gave me a good idea. But look at this code: void CLeftView::OnRclick(NMHDR* pNMHDR, LRESULT* pResult) { unsigned char *p = (unsigned char*) pNMHDR; p -= 4; // !!!!!!!!!!!!! NMTREEVIEW *z = (NMTREEVIEW*) p; CPoint ptXY = z->ptDrag; } It works too!!! ptXY after all of these manipulations is a real mouse coordinates X|

Trust me, your code is very bad idea for support etc, etc. Regrds, Sergey

http://www.mvps.org/vcfaq/mfc/6.htm /* Get the mouse cursor position */ DWORD dwPos = GetMessagePos(); More simple and portable. ;)
