  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. 
  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 overload 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 
  26     Virtual list control can be used as a normal one except that no operations 
  27     which can take time proportional to the number of items in the control happen 
  28     -- this is required to allow having a practically infinite number of items. 
  29     For example, in a multiple selection virtual list control, the selections won't 
  30     be sent when many items are selected at once because this could mean iterating 
  33     Using many of wxListCtrl features is shown in the 
  34     @ref page_samples_listctrl "corresponding sample". 
  36     To intercept events from a list control, use the event table macros described 
  39     <b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native 
  40     implementation for report mode, and uses a generic implementation for other 
  41     modes. You can use the generic implementation for report mode as well by setting 
  42     the @c mac.listctrl.always_use_generic system option (see wxSystemOption) to 1. 
  47            Multicolumn list view, with optional small icons. Columns are 
  48            computed automatically, i.e. you don't set columns as in 
  49            wxLC_REPORT. In other words, the list wraps, unlike a wxListBox. 
  51            Single or multicolumn report view, with optional header. 
  53            The application provides items text on demand. May only be used 
  56            Large icon view, with optional labels. 
  57     @style{wxLC_SMALL_ICON} 
  58            Small icon view, with optional labels. 
  59     @style{wxLC_ALIGN_TOP} 
  60            Icons align to the top. Win32 default, Win32 only. 
  61     @style{wxLC_ALIGN_LEFT} 
  62            Icons align to the left. 
  63     @style{wxLC_AUTOARRANGE} 
  64            Icons arrange themselves. Win32 only. 
  65     @style{wxLC_EDIT_LABELS} 
  66            Labels are editable: the application will be notified when editing 
  68     @style{wxLC_NO_HEADER} 
  69            No header in report mode. 
  70     @style{wxLC_SINGLE_SEL} 
  71            Single selection (default is multiple). 
  72     @style{wxLC_SORT_ASCENDING} 
  73            Sort in ascending order. (You must still supply a comparison callback 
  74            in wxListCtrl::SortItems.) 
  75     @style{wxLC_SORT_DESCENDING} 
  76            Sort in descending order. (You must still supply a comparison callback 
  77            in wxListCtrl::SortItems.) 
  79            Draws light horizontal rules between rows in report mode.

 535         If @a ptrSubItem is not @NULL and the wxListCtrl is in the report 
 536         mode the subitem (or column) number will also be provided. 
 537         This feature is only available in version 2.7.0 or higher and is currently only 
 538         implemented under wxMSW and requires at least comctl32.dll of verion 4.70 on 
 539         the host system or the value stored in @a ptrSubItem will be always -1. 
 540         To compile this feature into wxWidgets library you need to have access to 
 541         commctrl.h of version 4.70 that is provided by Microsoft.

 599         Redraws the given @e item. 
 601         This is only useful for the virtual list controls as without calling this 
 602         function the displayed value of the item doesn't change even when the 
 603         underlying data does change. 
 607     void RefreshItem(long item
); 
 610         Redraws the items between @a itemFrom and @e itemTo. 
 611         The starting item must be less than or equal to the ending one. 
 613         Just as RefreshItem() this is only useful for virtual list controls. 
 615     void RefreshItems(long itemFrom
, long itemTo
); 
 618         Scrolls the list control. If in icon, small icon or report view mode, 
 619         @a dx specifies the number of pixels to scroll. If in list view mode, 
 620         @a dx specifies the number of columns to scroll. @a dy always specifies 
 621         the number of pixels to scroll vertically. 
 623         @note This method is currently only implemented in the Windows version. 
 625     bool ScrollList(int dx

); 
 628         Sets the background colour. 
 630         Note that the wxWindow::GetBackgroundColour() function of wxWindow base 
 631         class can be used to retrieve the current background colour. 
 633     virtual bool SetBackgroundColour(const wxColour
& col
); 
 636         Sets information about this column. 
 637         See SetItem() for more information. 
 639     bool SetColumn(int col
, wxListItem
& item
); 
 642         Sets the column width. 
 644         @a width can be a width in pixels or @c wxLIST_AUTOSIZE (-1) or 
 645         @c wxLIST_AUTOSIZE_USEHEADER (-2). 
 647         @c wxLIST_AUTOSIZE will resize the column to the length of its longest item. 
 649         @c wxLIST_AUTOSIZE_USEHEADER will resize the column to the length of the 
 650         header (Win32) or 80 pixels (other platforms). 
 652         In small or normal icon view, @a col must be -1, and the column width is set 
 655     bool SetColumnWidth(int col
, int width
); 
 658         Changes the order in which the columns are shown. 
 660         By default, the columns of a list control appear on the screen in order 
 661         of their indices, i.e. the column 0 appears first, the column 1 next 
 662         and so on. However by using this function it is possible to arbitrarily 
 663         reorder the columns visual order and the user can also rearrange the 
 664         columns interactively by dragging them. In this case, the index of the 
 665         column is not the same as its order and the functions GetColumnOrder() 
 666         and GetColumnIndexFromOrder() should be used to translate between them. 
 667         Notice that all the other functions still work with the column indices, 
 668         i.e. the visual positioning of the columns on screen doesn't affect the 
 669         code setting or getting their values for example. 
 671         The @a orders array must have the same number elements as the number of 
 672         columns and contain each position exactly once. Its n-th element 
 673         contains the index of the column to be shown in n-th position, so for a 
 674         control with three columns passing an array with elements 2, 0 and 1 
 675         results in the third column being displayed first, the first one next 
 676         and the second one last. 
 680             wxListCtrl *list = new wxListCtrl(...); 
 681             for ( int i = 0; i < 3; i++ ) 
 682                 list->InsertColumn(i, wxString::Format("Column %d", i)); 
 688             list->SetColumnsOrder(order); 
 690             // now list->GetColumnsOrder() will return order and 
 691             // list->GetColumnIndexFromOrder(n) will return order[n] and 
 692             // list->GetColumnOrder() will return 1, 2 and 0 for the column 0, 
 693             // 1 and 2 respectively 
 696         Please notice that this function makes sense for report view only and 
 697         currently is only implemented in wxMSW port. To avoid explicit tests 
 698         for @c __WXMSW__ in your code, please use @c wxHAS_LISTCTRL_COLUMN_ORDER 
 699         as this will allow it to start working under the other platforms when 
 700         support for the column reordering is added there. 
 702         @see GetColumnsOrder() 
 704     bool SetColumnsOrder(const wxArrayInt

 707         Sets the image list associated with the control. 
 709         @a which is one of @c wxIMAGE_LIST_NORMAL, @c wxIMAGE_LIST_SMALL, 
 710         @c wxIMAGE_LIST_STATE (the last is unimplemented). 
 712         This method does not take ownership of the image list, you have to 
 715         @see AssignImageList() 
 717     void SetImageList(wxImageList

, int which
); 
 720         Sets the data of an item. 
 722         Using the wxListItem's mask and state mask, you can change only selected 
 723         attributes of a wxListCtrl item. 
 725     bool SetItem(wxListItem
& info
); 
 728         Sets an item string field at a particular column. 
 730     long SetItem(long index
, int column
, const wxString
& label
, int imageId 
= -1); 
 733         Sets the background colour for this item. 
 734         This function only works in report view mode. 
 735         The colour can be retrieved using GetItemBackgroundColour(). 
 737     void SetItemBackgroundColour(long item
, const wxColour
& col
); 
 740         Sets the image associated with the item. 
 741         In report view, you can specify the column. 
 742         The image is an index into the image list associated with the list control. 
 744     bool SetItemColumnImage(long item
, long column
, int image
); 
 747         This method can only be used with virtual list controls. 
 749         It is used to indicate to the control the number of items it contains. 
 750         After calling it, the main program should be ready to handle calls to 
 751         various item callbacks (such as wxListCtrl::OnGetItemText) for all 
 752         items in the range from 0 to @a count. 
 754         Notice that the control is not necessarily redrawn after this call as 
 755         it may be undesirable if an item which is not visible on the screen 
 756         anyhow was added to or removed from a control displaying many items, if 
 757         you do need to refresh the display you can just call Refresh() manually. 
 759     void SetItemCount(long count
); 
 762         Associates application-defined data with this item. 
 764         Notice that this function cannot be used to associate pointers with the control 
 765         items, use SetItemPtrData() instead. 
 767     bool SetItemData(long item
, long data
); 
 770          Sets the item's font. 
 772     void SetItemFont(long item
, const wxFont
& font
); 
 775         Sets the unselected and selected images associated with the item. 
 776         The images are indices into the image list associated with the list control. 
 778     bool SetItemImage(long item
, int image
, int selImage 
= -1); 
 781         Sets the unselected and selected images associated with the item. 
 782         The images are indices into the image list associated with the list control. 
 785         This form is deprecated: @a selImage is not used; use the other 
 786         SetItemImage() overload. 
 788     bool SetItemImage(long item
, int image
, int selImage 
= -1); 
 791         Sets the position of the item, in icon or small icon view. Windows only. 
 793     bool SetItemPosition(long item
, const wxPoint
& pos
); 
 796         Associates application-defined data with this item. 
 798         The @a data parameter may be either an integer or a pointer cast to the 
 799         @c wxUIntPtr type which is guaranteed to be large enough to be able to 
 800         contain all integer types and pointers. 
 804     bool SetItemPtrData(long item
, wxUIntPtr data
); 
 807         Sets the item state. For a list of state flags, see SetItem(). 
 808         The @b stateMask indicates which state flags are valid. 
 810     bool SetItemState(long item
, long state
, long stateMask
); 
 813         Sets the item text for this item. 
 815     void SetItemText(long item
, const wxString
& text
); 
 818         Sets the colour for this item. 
 819         This function only works in report view. 
 820         The colour can be retrieved using GetItemTextColour(). 
 822     void SetItemTextColour(long item
, const wxColour
& col
); 
 825         Adds or removes a single window style. 
 827     void SetSingleStyle(long style
, bool add 
= true); 
 830         Sets the text colour of the list control. 
 832     void SetTextColour(const wxColour
& col
); 
 835         Sets the whole window style, deleting all items. 
 837     void SetWindowStyleFlag(long style
); 
 840         Call this function to sort the items in the list control. Sorting is done 
 841         using the specified @a fnSortCallBack function. This function must have the 
 844         int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData) 
 847         It is called each time when the two items must be compared and should return 0 
 848         if the items are equal, negative value if the first item is less than the 
 849         second one and positive value if the first one is greater than the second one 
 850         (the same convention as used by @c qsort(3)). 
 852         The parameter @e item1 is the client data associated with the first item (NOT the index). 
 853         The parameter @e item2 is the client data associated with the second item (NOT the index). 
 854         The parameter @e data is the value passed to SortItems() itself. 
 856         Notice that the control may only be sorted on client data associated with 
 857         the items, so you must use SetItemData if you want to be able to sort the 
 858         items in the control. 
 860         Please see the @ref page_samples_listctrl for an example of using this function. 
 862     bool SortItems(wxListCtrlCompare fnSortCallBack
, long data
); 
 867         This function may be overloaded in the derived class for a control with 
 868         @c wxLC_VIRTUAL style. It should return the attribute for the specified 
 869         @c item or @NULL to use the default appearance parameters. 
 871         wxListCtrl will not delete the pointer or keep a reference of it. 
 872         You can return the same wxListItemAttr pointer for every OnGetItemAttr() call. 
 874         The base class version always returns @NULL.

 895         (if the control doesn't have an image list, it is not necessary to overload it). 
 896         It should return the index of the items image in the controls image list 
 899         In a control with @c wxLC_REPORT style, OnGetItemImage() only gets called for 
 900         the first column of each line.

1075         Default Constructor. 
1080         Construct a wxListItemAttr with the specified foreground and 
1081         background colors and font. 
1083     wxListItemAttr(const wxColour

, 
1084                    const wxColour
& colBack

1093         Returns the currently set font. 
1095     const wxFont

1103         Returns @true if the currently set background color is valid. 
1105     bool HasBackgroundColour() const; 
1108         Returns @true if the currently set font is valid. 
1110     bool HasFont() const; 
1113         Returns @true if the currently set text color is valid. 
1115     bool HasTextColour() const; 
1118         Sets a new background color.

1128         Sets a new text color. 
1130     void SetTextColour(const wxColour

1138     This class currently simply presents a simpler to use interface for the 
1139     wxListCtrl -- it can be thought of as a @e façade for that complicated class. 
1141     Using it is preferable to using wxListCtrl directly whenever possible because 
1142     in the future some ports might implement wxListView but not the full set of 
1143     wxListCtrl features. 
1145     Other than different interface, this class is identical to wxListCtrl. 
1146     In particular, it uses the same events, same window styles and so on.

1170     void Focus(long index
); 
1173         Returns the first selected item in a (presumably) multiple selection control. 
1174         Together with GetNextSelected() it can be used to iterate over all selected 
1175         items in the control. 
1177         @return The first selected item, if any, -1 otherwise.

1218         To use the column images, the control must have a valid image list with 
1222             the column to set image for 
1224             the index of the column image in the controls image list

1244     This class stores information about a wxListCtrl item or column. 
1246     wxListItem is a class which contains informations about: 
1247     - Zero based item position; see SetId() and GetId(). 
1248     - Zero based column index; see SetColumn() and GetColumn(). 
1249     - The label (or header for columns); see SetText() and GetText(). 
1250     - The zero based index into an image list; see GetImage() and SetImage(). 
1251     - Application defined data; see SetData() and GetData(). 
1252     - For columns only: the width of the column; see SetWidth() and GetWidth(). 
1253     - For columns only: the format of the column; one of @c wxLIST_FORMAT_LEFT, 
1254       @c wxLIST_FORMAT_RIGHT, @c wxLIST_FORMAT_CENTRE. See SetAlign() and GetAlign(). 
1255     - The state of the item; see SetState() and GetState(). 
1256       This is a bitlist of the following flags: 
1257         - @c wxLIST_STATE_FOCUSED: The item has the focus. 
1258         - @c wxLIST_STATE_SELECTED: The item is selected. 
1259         - @c wxLIST_STATE_DONTCARE: Don't care what the state is. Win32 only. 
1260         - @c wxLIST_STATE_DROPHILITED: The item is highlighted to receive a drop event. Win32 only. 
1261         - @c wxLIST_STATE_CUT: The item is in the cut state. Win32 only. 
1262     - A mask indicating which state flags are valid; this is a bitlist of the 
1263       flags reported above for the item state. See SetStateMask() and GetStateMask(). 
1264     - A mask indicating which fields of this class are valid; see SetMask() and GetMask(). 
1265       This is a bitlist of the following flags: 
1266         - @c wxLIST_MASK_STATE: The state field is valid. 
1267         - @c wxLIST_MASK_TEXT: The label field is valid. 
1268         - @c wxLIST_MASK_IMAGE: The image field is valid. 
1269         - @c wxLIST_MASK_DATA: The application-defined data field is valid. 
1270         - @c wxLIST_MASK_WIDTH: The column width field is valid. 
1271         - @c wxLIST_MASK_FORMAT: The column format field is valid. 
1273     The wxListItem object can also contain item-specific colour and font 
1274     information: for this you need to call one of SetTextColour(), SetBackgroundColour() 
1275     or SetFont() functions on it passing it the colour/font to use. 
1276     If the colour/font is not specified, the default list control colour/font is used.
