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. | |

827 | By default, the columns of a list control appear on the screen in order | |

831 | columns interactively by dragging them. In this case, the index of the | |
832 | column is not the same as its order and the functions GetColumnOrder() | |
833 | and GetColumnIndexFromOrder() should be used to translate between them. | |
834 | Notice that all the other functions still work with the column indices, | |
835 | i.e. the visual positioning of the columns on screen doesn't affect the | |
836 | code setting or getting their values for example. | |
837 | ||
838 | The @a orders array must have the same number elements as the number of | |
839 | columns and contain each position exactly once. Its n-th element | |
840 | contains the index of the column to be shown in n-th position, so for a | |
841 | control with three columns passing an array with elements 2, 0 and 1 | |
842 | results in the third column being displayed first, the first one next | |
843 | and the second one last. | |
844 | ||
845 | Example of using it: | |
846 | @code | |
847 | wxListCtrl *list = new wxListCtrl(...); | |
848 | for ( int i = 0; i < 3; i++ ) | |
849 | list->InsertColumn(i, wxString::Format("Column %d", i)); | |
850 | ||
851 | wxArrayInt order(3); | |
852 | order[0] = 2; | |
853 | order[1] = 0; | |
854 | order[2] = 1; | |
855 | list->SetColumnsOrder(order); | |
856 | ||
857 | // now list->GetColumnsOrder() will return order and | |
858 | // list->GetColumnIndexFromOrder(n) will return order[n] and | |

1447 | - The state of the item; see SetState() and GetState(). | |
1448 | This is a bitlist of the following flags: | |
