10 @class wxListCtrl
11
12 A list control presents lists in a number of formats: list view, report view,
13 icon view and small icon view. In any case, elements are numbered from zero.
14 For all these modes, the items are stored in the control and must be added to
15 it using wxListCtrl::InsertItem method.
16
17 A special case of report view quite different from the other modes of the list
18 control is a virtual control in which the items data (including text, images
19 and attributes) is managed by the main program and is requested by the control
20 itself only when needed which allows to have controls with millions of items
21 without consuming much memory. To use virtual list control you must use
22 wxListCtrl::SetItemCount first and override at least wxListCtrl::OnGetItemText
23 (and optionally wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
24 wxListCtrl::OnGetItemAttr) to return the information about the items when the
25 control requests it.
26
27 Virtual list control can be used as a normal one except that no operations
28 which can take time proportional to the number of items in the control happen
29 -- this is required to allow having a practically infinite number of items.
30 For example, in a multiple selection virtual list control, the selections won't
31 be sent when many items are selected at once because this could mean iterating
32 over all the items.
33
34 Using many of wxListCtrl features is shown in the
35 @ref page_samples_listctrl "corresponding sample".
36
37 To intercept events from a list control, use the event table macros described
38 in wxListEvent.
39
40 <b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native
41 implementation for report mode, and uses a generic implementation for other
42 modes. You can use the generic implementation for report mode as well by setting
43 the @c mac.listctrl.always_use_generic system option (see wxSystemOptions) to 1.
44
45
46 @beginStyleTable
47 @style{wxLC_LIST}
48 Multicolumn list view, with optional small icons. Columns are
49 computed automatically, i.e. you don't set columns as in
50 @c wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
51 @style{wxLC_REPORT}
52 Single or multicolumn report view, with optional header.
53 @style{wxLC_VIRTUAL}
54 The application provides items text on demand. May only be used
55 with @c wxLC_REPORT.
56 @style{wxLC_ICON}
57 Large icon view, with optional labels.
58 @style{wxLC_SMALL_ICON}
59 Small icon view, with optional labels.
60 @style{wxLC_ALIGN_TOP}
61 Icons align to the top. Win32 default, Win32 only.
62 @style{wxLC_ALIGN_LEFT}
63 Icons align to the left.
64 @style{wxLC_AUTOARRANGE}
65 Icons arrange themselves. Win32 only.
66 @style{wxLC_EDIT_LABELS}
67 Labels are editable: the application will be notified when editing
68 starts.
69 @style{wxLC_NO_HEADER}
70 No header in report mode.
71 @style{wxLC_SINGLE_SEL}
72 Single selection (default is multiple).
73 @style{wxLC_SORT_ASCENDING}
74 Sort in ascending order. (You must still supply a comparison callback
75 in wxListCtrl::SortItems.)
76 @style{wxLC_SORT_DESCENDING}
77 Sort in descending order. (You must still supply a comparison callback
78 in wxListCtrl::SortItems.)
79 @style{wxLC_HRULES}
80 Draws light horizontal rules between rows in report mode.
81 @style{wxLC_VRULES}
82 Draws light vertical rules between columns in report mode.

772 By default, the columns of a list control appear on the screen in order
773 of their indices, i.e. the column 0 appears first, the column 1 next
774 and so on. However by using this function it is possible to arbitrarily
775 reorder the columns visual order and the user can also rearrange the
776 columns interactively by dragging them. In this case, the index of the
777 column is not the same as its order and the functions GetColumnOrder()
778 and GetColumnIndexFromOrder() should be used to translate between them.
779 Notice that all the other functions still work with the column indices,
780 i.e. the visual positioning of the columns on screen doesn't affect the
781 code setting or getting their values for example.
782
783 The @a orders array must have the same number elements as the number of
784 columns and contain each position exactly once. Its n-th element
785 contains the index of the column to be shown in n-th position, so for a
786 control with three columns passing an array with elements 2, 0 and 1
787 results in the third column being displayed first, the first one next
788 and the second one last.
789
790 Example of using it:
791 @code
792 wxListCtrl *list = new wxListCtrl(...);
793 for ( int i = 0; i < 3; i++ )
794 list->InsertColumn(i, wxString::Format("Column %d", i));

797 order[0] = 2;
798 order[1] = 0;
799 order[2] = 1;

801
802 // now list->GetColumnsOrder() will return order and
803 // list->GetColumnIndexFromOrder(n) will return order[n] and

1385 - Zero based column index; see SetColumn() and GetColumn().
1386 - The label (or header for columns); see SetText() and GetText().
1387 - The zero based index into an image list; see GetImage() and SetImage().
1388 - Application defined data; see SetData() and GetData().
1389 - For columns only: the width of the column; see SetWidth() and GetWidth().
1390 - For columns only: the format of the column; one of @c wxLIST_FORMAT_LEFT,
1391 @c wxLIST_FORMAT_RIGHT, @c wxLIST_FORMAT_CENTRE. See SetAlign() and GetAlign().
1392 - The state of the item; see SetState() and GetState().
1393 This is a bitlist of the following flags:
1394 - @c wxLIST_STATE_FOCUSED: The item has the focus.
1395 - @c wxLIST_STATE_SELECTED: The item is selected.
1396 - @c wxLIST_STATE_DONTCARE: Don't care what the state is. Win32 only.
1397 - @c wxLIST_STATE_DROPHILITED: The item is highlighted to receive a drop event. Win32 only.
1398 - @c wxLIST_STATE_CUT: The item is in the cut state. Win32 only.
1399 - A mask indicating which state flags are valid; this is a bitlist of the
1400 flags reported above for the item state. See SetStateMask() and GetStateMask().
1401 - A mask indicating which fields of this class are valid; see SetMask() and GetMask().
1402 This is a bitlist of the following flags:
1403 - @c wxLIST_MASK_STATE: The state field is valid.
1404 - @c wxLIST_MASK_TEXT: The label field is valid.
1405 - @c wxLIST_MASK_IMAGE: The image field is valid.
