clistctrl

问题 There is a CListCtrl with SetExtendedStyle (LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT) , a single selection is false. I want to be able to select multiple lines with the mouse. When starting selection from an empty area, it works: It does not work if I start the selection not from an empty area. Selection frame does not appear: How to make it work? 回答1: It is not really a good idea to change how a common control works because users expect them to function like they do in all other applications.

问题 I want to execute some code when the user selects a row in a CListCtrl (report view, I don't care about the other viewing modes). How do I catch this event? is there some message I can map or a method like "OnSelectionChanged" or something like that? 回答1: Also try: BEGIN_MESSAGE_MAP(cDlgRun, CDialog) ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST2, OnItemchangedList2) END_MESSAGE_MAP() /* ... */ void cDlgRun::OnItemchangedList2(NMHDR* pNMHDR, LRESULT* pResult) { NM_LISTVIEW* pNMListView = (NM_LISTVIEW*

问题 I am creating a MFC application for Windows Mobile and don't know how to enable multiple selection for List Control (CListCtrl). In properties panel Single Selection is set to False but still can't select multiple items. Any idea? 回答1: I have never targeted Windows Mobile but you might try the following: list.ModifyStyle(LVS_SINGLESEL, 0); 回答2: ModifyStyle method of CWnd base will work (see post from Diego) if you desire to do this programmatically OR you can define the attribute within the

问题 How can I maintain the horizontal scroll bar position of a CListCtrl? I periodically dump and repopulate the contents of the list control so without explicitly remembering the old position and restoring it the scroll just goes back to the top left. I asked a related question, CListCtrl: How to maintain scroll position?, earlier but at the time I was only interested in vertical scroll position and the answer supplied solved that. However, now I want to remember and restore the horizontal

问题 I have a CListCtrl (report style) where I clear the list and repopulate it at certain times. I'd like to maintain the vertical scroll position when doing this. I see there are a couple methods that look promising: EnsureVisible() GetScrollPos() SetScrollPos() GetScrollInfo() GetTopIndex() Scroll() I'm trying GetScrollPos() and then SetScrollPos() but it doesn't appear to be working. What is the simple correct way to save a scroll position and then later restore it? UPDATE Actually it seems I

问题 The List Control is defined as Single Selection on the resources. Question 1 I want to have a checkbox on the header of first column of my CListCtrl . On the OnInitDialog I have m_list.SetExtendedStyle(m_list.GetExtendedStyle() | LVS_EX_CHECKBOXES | LVS_EX_FULLROWSELECT); CString s; s.LoadString(IDS_COLUMN1); #ifndef HDS_CHECKBOXES // Copied from Microsoft SDKs\Windows\v7.0A\Include\CommCtrl.h #define HDS_CHECKBOXES 0x0400 #endif CHeaderCtrl& header = *m_list.GetHeaderCtrl(); header

问题 I'm trying to get the order of the columns in an MFC CListCtrl . Initially I tried calling GetColumnOrderArray() in a message handler for the HDN_ENDDRAG notification, but that always returned the old (pre-drag and drop) column order. So, based on the advice in this SO post's comment, I tried handling both the HDN_BEGINDRAG and the HDN_ENDDRAG and grabbing the old and new column orders with phdr->pitem->iOrder . But pitem is always NULL for me in the both handlers. No idea why. SOOO I tried

问题 I have a class that is derived from a CListCtrl. I want the widths of all the columns to total the width of the display Window, so that I don't get the bottom scrollbar. I can get the width of standard scrollbars vai the GetSystemMetrics(SM_CXVSCROLL) call, but I don't know how to tell if the vertical scrollbar is active. I've tried to use: auto pScrollbar = GetScrollBarCtrl(SB_VERT); auto is_visible = pScrollbar && pScrollbar->IsWindowVisible(); But pScrollbar is always a nullptr . I've
