and attributes) is managed by the main program and is requested by the control
itself only when needed which allows to have controls with millions of items
without consuming much memory. To use virtual list control you must use
- wxListCtrl::SetItemCount first and overload at least
- wxListCtrl::OnGetItemText (and optionally
- wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
- wxListCtrl::OnGetItemAttr) to return the information
- about the items when the control requests it. Virtual list control can be used
- as a normal one except that no operations which can take time proportional to
- the number of items in the control happen -- this is required to allow having a
- practically infinite number of items. For example, in a multiple selection
- virtual list control, the selections won't be sent when many items are selected
- at once because this could mean iterating over all the items.

Using many of wxListCtrl features is shown in the
- @ref overview_samplelistctrl "corresponding sample".
+ @ref page_samples_listctrl "corresponding sample".
To intercept events from a list control, use the event table macros described
in wxListEvent.
- @b Mac Note: Starting with 2.8, wxListCtrl uses a native implementation for
- report mode, and uses a generic implementation for other modes. You can use the
- generic implementation for report mode as well by setting the
- mac.listctrl.always_use_generic wxSystemOption() to 1.
-
- Column reordering (only wxMSW): In report view, the control has several columns
- which are identified by their internal indices. By default, these indices
- correspond to their order on screen, i.e. the column 0 appears first (in the
- left-to-right or maybe right-to-left if the current language uses this writing
- direction), the column 1 next and so on. However it is possible to reorder the
- columns visual order using SetColumnsOrder() method and the user can also
- rearrange the columns interactively by dragging them. In this case, the index
- of the column is not the same as its order and the functions GetColumnOrder() and
- GetColumnIndexFromOrder() should be used to translate between them.
+ <b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native

+
+ By default, the columns of a list control appear on the screen in order
+ of their indices, i.e. the column 0 appears first, the column 1 next
+ and so on. However by using this function it is possible to arbitrarily
+ reorder the columns visual order and the user can also rearrange the

+ column is not the same as its order and the functions GetColumnOrder()
+ and GetColumnIndexFromOrder() should be used to translate between them.
+ Notice that all the other functions still work with the column indices,
+ i.e. the visual positioning of the columns on screen doesn't affect the
+ code setting or getting their values for example.
+
+ The @a orders array must have the same number elements as the number of
+ columns and contain each position exactly once. Its n-th element
+ contains the index of the column to be shown in n-th position, so for a
+ control with three columns passing an array with elements 2, 0 and 1
+ results in the third column being displayed first, the first one next
+ and the second one last.
+
+ Example of using it:
+ @code
+ wxListCtrl *list = new wxListCtrl(...);
+ for ( int i = 0; i < 3; i++ )
+ list->InsertColumn(i, wxString::Format("Column %d", i));
+
+ wxArrayInt order(3);
+ order[0] = 2;
+ order[1] = 0;
+ order[2] = 1;
+ list->SetColumnsOrder(order);
+
+ // now list->GetColumnsOrder() will return order and
+ // list->GetColumnIndexFromOrder(n) will return order[n] and
+ // list->GetColumnOrder() will return 1, 2 and 0 for the column 0,
+ // 1 and 2 respectively
+ @endcode
+
+ Please notice that this function makes sense for report view only and
+ currently is only implemented in wxMSW port. To avoid explicit tests
+ for @c __WXMSW__ in your code, please use @c wxHAS_LISTCTRL_COLUMN_ORDER

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