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 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
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
34 Using many of wxListCtrl features is shown in the
35 @ref page_samples_listctrl "corresponding sample".
37 To intercept events from a list control, use the event table macros described
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.
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.
52 Single or multicolumn report view, with optional header.
54 The application provides items text on demand. May only be used
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
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.)

180 Arranges the items in icon or small icon view.
181 This only has effect on Win32. @a flag is one of:
182 - wxLIST_ALIGN_DEFAULT: Default alignment.
183 - wxLIST_ALIGN_LEFT: Align to the left side of the control.
184 - wxLIST_ALIGN_TOP: Align to the top side of the control.

215 Deletes all items in the list control.
217 @note This function does @e not send the @c wxEVT_COMMAND_LIST_DELETE_ITEM
218 event because deleting many items from the control would be too slow
219 then (unlike wxListCtrl::DeleteItem).
221 bool DeleteAllItems();

233 @see DeleteAllItems()
235 bool DeleteItem(long item
);
238 Starts editing the label of the given item.
240 This function generates a @c EVT_LIST_BEGIN_LABEL_EDIT event which can be
241 vetoed so that no text control will appear for in-place editing.
243 If the user changed the label (i.e. s/he does not press ESC or leave
244 the text control without changes, a @c EVT_LIST_END_LABEL_EDIT event
245 will be sent which can be vetoed as well.

251 Finish editing the label.
253 This method allows to programmatically end editing a list control item
254 in place. Usually it will only be called when editing is in progress,
255 i.e. if GetEditControl() returns non-NULL. In particular, do not call
256 it from EVT_LIST_BEGIN_LABEL_EDIT handler as the edit control is not
257 yet fully created by then, just veto the event in this handler instead
258 to prevent the editing from even starting.
260 Notice that calling this method will result in EVT_LIST_END_LABEL_EDIT
261 event being generated.
263 Currently only implemented in wxMSW.

325 Returns the number of columns.
327 int GetColumnCount() const;
330 Gets the column index from its position in visual order.
332 After calling SetColumnsOrder(), the index returned by this function

344 Gets the column visual order position.
346 This function returns the index of the column which appears at the
347 given visual position, e.g. calling it with @a col equal to 0 returns
348 the index of the first shown column.

379 int GetCountPerPage() const;
382 Returns the edit control being currently used to edit a label.
383 Returns @NULL if no label is being edited.
385 @note It is currently only implemented for wxMSW and the generic version,
386 not for the native Mac OS X version.
388 wxTextCtrl
* GetEditControl() const;
391 Returns the specified image list. @a which may be one of:
392 - wxIMAGE_LIST_NORMAL: The normal (large icon) image list.
393 - wxIMAGE_LIST_SMALL: The small icon image list.
394 - wxIMAGE_LIST_STATE: The user-defined state image list (unimplemented).
396 wxImageList
* GetImageList(int which
) const;
399 Gets information about the item. See SetItem() for more information.
401 You must call @e info.SetId() to set the ID of item you're interested in
402 before calling this method, and @e info.SetMask() with the flags indicating
403 what fields you need to retrieve from @a info.
406 In wxPerl this method takes as parameter the ID of the item
407 and (optionally) the column, and returns a Wx::ListItem object.
410 bool GetItem(wxListItem
& info
) const;
413 Returns the colour for this item.
414 If the item has no specific colour, returns an invalid colour
415 (and not the default background control of the control itself).

457 bool GetItemRect(long item
, wxRect
& rect
,

462 returned as @c x component of the wxSize object and the vertical spacing
463 as its @c y component.
465 wxSize
GetItemSpacing() const;
468 Gets the item state. For a list of state flags, see SetItem().
469 The @a stateMask indicates which state flags are of interest.
471 int GetItemState(long item
, long stateMask
) const;
474 Gets the item text for this item.
477 Item (zero-based) index.
479 Item column (zero-based) index. Column 0 is the default. This
480 parameter is new in wxWidgets 2.9.1.
482 wxString
GetItemText(long item
, int col
= 0) const;
485 Returns the colour for this item.
487 If the item has no specific colour, returns an invalid colour (and not the
488 default foreground control of the control itself as this wouldn't allow
489 distinguishing between items having the same colour as the current control
490 foreground and items with default colour which, hence, have always the
491 same colour as the control).
493 wxColour
GetItemTextColour(long item
) const;
496 Searches for an item with the given geometry or state, starting from
497 @a item but excluding the @a item itself.
499 If @a item is -1, the first item that matches the specified flags will be returned.
500 Returns the first item with given state following @a item or -1 if no such item found.
501 This function may be used to find all selected items in the control like this:
507 item = listctrl->GetNextItem(item,
509 wxLIST_STATE_SELECTED);
513 // this item is selected - do whatever is needed with it
514 wxLogMessage("Item %ld is selected.", item);
518 @a geometry can be one of:
519 - wxLIST_NEXT_ABOVE: Searches for an item above the specified item.
520 - wxLIST_NEXT_ALL: Searches for subsequent item by index.
521 - wxLIST_NEXT_BELOW: Searches for an item below the specified item.
522 - wxLIST_NEXT_LEFT: Searches for an item to the left of the specified item.
523 - wxLIST_NEXT_RIGHT: Searches for an item to the right of the specified item.
525 @note this parameter is only supported by wxMSW currently and ignored on
528 @a state can be a bitlist of the following:
529 - wxLIST_STATE_DONTCARE: Don't care what the state is.
530 - wxLIST_STATE_DROPHILITED: The item indicates it is a drop target.
531 - wxLIST_STATE_FOCUSED: The item has the focus.
532 - wxLIST_STATE_SELECTED: The item is selected.
533 - wxLIST_STATE_CUT: The item is selected as part of a cut and paste operation.
535 long GetNextItem(long item

539 Returns the number of selected items in the list control.
541 int GetSelectedItemCount() const;
544 Returns the rectangle representing the size and position, in physical
545 coordinates, of the given subitem, i.e. the part of the row @a item in the
548 This method is only meaningfull when the wxListCtrl is in the report mode.
549 If @a subItem parameter is equal to the special value
550 @c wxLIST_GETSUBITEMRECT_WHOLEITEM the return value is the same as
553 @a code can be one of @c wxLIST_RECT_BOUNDS, @c wxLIST_RECT_ICON or
554 @c wxLIST_RECT_LABEL.
558 bool GetSubItemRect(long item
, long subItem

GetTextColour() const;
567 Gets the index of the topmost visible item when in list or report view.
569 long GetTopItem() const;
572 Returns the rectangle taken by all items in the control. In other words, if the
573 controls client size were equal to the size of this rectangle, no scrollbars
574 would be needed and no free space would be left.
576 Note that this function only works in the icon and small icon views, not in
577 list or report views (this is a limitation of the native Win32 control).
579 wxRect
GetViewRect() const;
582 Determines which item (if any) is at the specified point, giving details
583 in @a flags. Returns index of the item or @c wxNOT_FOUND if no item is at
586 @a flags will be a combination of the following flags:
587 - wxLIST_HITTEST_ABOVE: Above the client area.
588 - wxLIST_HITTEST_BELOW: Below the client area.
589 - wxLIST_HITTEST_NOWHERE: In the client area but below the last item.

591 - wxLIST_HITTEST_ONITEMLABEL: On the label (string) associated with an item.
592 - wxLIST_HITTEST_ONITEMRIGHT: In the area to the right of an item.
593 - wxLIST_HITTEST_ONITEMSTATEICON: On the state icon for a tree view item
594 that is in a user-defined state.
595 - wxLIST_HITTEST_TOLEFT: To the right of the client area.
596 - wxLIST_HITTEST_TORIGHT: To the left of the client area.
597 - wxLIST_HITTEST_ONITEM: Combination of @c wxLIST_HITTEST_ONITEMICON,
598 @c wxLIST_HITTEST_ONITEMLABEL, @c wxLIST_HITTEST_ONITEMSTATEICON.
600 If @a ptrSubItem is not @NULL and the wxListCtrl is in the report
601 mode the subitem (or column) number will also be provided.
602 This feature is only available in version 2.7.0 or higher and is currently only
603 implemented under wxMSW and requires at least comctl32.dll of verion 4.70 on
604 the host system or the value stored in @a ptrSubItem will be always -1.
605 To compile this feature into wxWidgets library you need to have access to
606 commctrl.h of version 4.70 that is provided by Microsoft.
609 In wxPerl this method only takes the @a point parameter
610 and returns a 2-element list (item, flags).

650 Insert an image item.
653 Index of the new item, supplied by the application
655 Index into the image list associated with this control and view style
658 In wxPerl this method is implemented as InsertImageItem(index, imageIndex).
661 long InsertItem(long index

664 Insert an image/string item.
667 Index of the new item, supplied by the application
671 Index into the image list associated with this control and view style
674 In wxPerl this method is implemented as InsertImageStringItem(index, label, imageIndex).
677 long InsertItem(long index
, const wxString
& label
,
681 Redraws the given @e item.
683 This is only useful for the virtual list controls as without calling this
684 function the displayed value of the item doesn't change even when the
685 underlying data does change.
689 void RefreshItem(long item
);
692 Redraws the items between @a itemFrom and @e itemTo.
693 The starting item must be less than or equal to the ending one.
695 Just as RefreshItem() this is only useful for virtual list controls.
697 void RefreshItems(long itemFrom
, long itemTo
);
700 Scrolls the list control. If in icon, small icon or report view mode,
701 @a dx specifies the number of pixels to scroll. If in list view mode,
702 @a dx specifies the number of columns to scroll. @a dy always specifies
703 the number of pixels to scroll vertically.
705 @note This method is currently only implemented in the Windows version.
707 bool ScrollList(int dx
, int dy
);
710 Sets the background colour.
712 Note that the wxWindow::GetBackgroundColour() function of wxWindow base
713 class can be used to retrieve the current background colour.
715 virtual bool SetBackgroundColour(const wxColour
& col
);
718 Sets information about this column.
719 See SetItem() for more information.
721 bool SetColumn(int col
, wxListItem
& item
);
724 Sets the column width.
726 @a width can be a width in pixels or @c wxLIST_AUTOSIZE (-1) or
727 @c wxLIST_AUTOSIZE_USEHEADER (-2).
729 @c wxLIST_AUTOSIZE will resize the column to the length of its longest item.
731 @c wxLIST_AUTOSIZE_USEHEADER will resize the column to the length of the
732 header (Win32) or 80 pixels (other platforms).
734 In small or normal icon view, @a col must be -1, and the column width is set
737 bool SetColumnWidth(int col
, int width
);
740 Changes the order in which the columns are shown.
742 By default, the columns of a list control appear on the screen in order
743 of their indices, i.e. the column 0 appears first, the column 1 next
744 and so on. However by using this function it is possible to arbitrarily
745 reorder the columns visual order and the user can also rearrange the
746 columns interactively by dragging them. In this case, the index of the
747 column is not the same as its order and the functions GetColumnOrder()
748 and GetColumnIndexFromOrder() should be used to translate between them.
749 Notice that all the other functions still work with the column indices,
750 i.e. the visual positioning of the columns on screen doesn't affect the
751 code setting or getting their values for example.
753 The @a orders array must have the same number elements as the number of
754 columns and contain each position exactly once. Its n-th element
755 contains the index of the column to be shown in n-th position, so for a
756 control with three columns passing an array with elements 2, 0 and 1
757 results in the third column being displayed first, the first one next
758 and the second one last.
762 wxListCtrl *list = new wxListCtrl(...);
763 for ( int i = 0; i < 3; i++ )
764 list->InsertColumn(i, wxString::Format("Column %d", i));

778 Please notice that this function makes sense for report view only and
779 currently is only implemented in wxMSW port. To avoid explicit tests
780 for @c __WXMSW__ in your code, please use @c wxHAS_LISTCTRL_COLUMN_ORDER
781 as this will allow it to start working under the other platforms when
782 support for the column reordering is added there.
784 @see GetColumnsOrder()
786 bool SetColumnsOrder(const wxArrayInt
& orders
) const;
789 Sets the image list associated with the control.
791 @a which is one of @c wxIMAGE_LIST_NORMAL, @c wxIMAGE_LIST_SMALL,
792 @c wxIMAGE_LIST_STATE (the last is unimplemented).
794 This method does not take ownership of the image list, you have to
797 @see AssignImageList()
799 void SetImageList(wxImageList
* imageList
, int which
);
802 Sets the data of an item.
804 Using the wxListItem's mask and state mask, you can change only selected
805 attributes of a wxListCtrl item.
807 bool SetItem(wxListItem
& info
);
810 Sets an item string field at a particular column.
812 long SetItem(long index
, int column
, const wxString
& label
, int imageId
= -1);
815 Sets the background colour for this item.
816 This function only works in report view mode.
817 The colour can be retrieved using GetItemBackgroundColour().
819 void SetItemBackgroundColour(long item
, const wxColour
& col
);
822 Sets the image associated with the item.
823 In report view, you can specify the column.
824 The image is an index into the image list associated with the list control.
826 bool SetItemColumnImage(long item
, long column
, int image
);
829 This method can only be used with virtual list controls.
831 It is used to indicate to the control the number of items it contains.
832 After calling it, the main program should be ready to handle calls to
833 various item callbacks (such as wxListCtrl::OnGetItemText) for all
834 items in the range from 0 to @a count.
836 Notice that the control is not necessarily redrawn after this call as
837 it may be undesirable if an item which is not visible on the screen
838 anyhow was added to or removed from a control displaying many items, if
839 you do need to refresh the display you can just call Refresh() manually.
841 void SetItemCount(long count
);
844 Associates application-defined data with this item.
846 Notice that this function cannot be used to associate pointers with the control
847 items, use SetItemPtrData() instead.
849 bool SetItemData(long item
, long data
);
852 Sets the item's font.
854 void SetItemFont(long item
, const wxFont
& font
);
857 Sets the unselected and selected images associated with the item.
858 The images are indices into the image list associated with the list control.
860 bool SetItemImage(long item
, int image
, int selImage
= -1);
863 Sets the unselected and selected images associated with the item.
864 The images are indices into the image list associated with the list control.
867 This form is deprecated: @a selImage is not used; use the other
868 SetItemImage() overload.
870 bool SetItemImage(long item
, int image
, int selImage
= -1);
873 Sets the position of the item, in icon or small icon view. Windows only.
875 bool SetItemPosition(long item
, const wxPoint
& pos
);
878 Associates application-defined data with this item.
880 The @a data parameter may be either an integer or a pointer cast to the
881 @c wxUIntPtr type which is guaranteed to be large enough to be able to
882 contain all integer types and pointers.
886 bool SetItemPtrData(long item
, wxUIntPtr data
);
889 Sets the item state. For a list of state flags, see SetItem().
890 The @b stateMask indicates which state flags are valid.
892 bool SetItemState(long item
, long state
, long stateMask
);
895 Sets the item text for this item.
897 void SetItemText(long item
, const wxString
& text
);
900 Sets the colour for this item.
901 This function only works in report view.
902 The colour can be retrieved using GetItemTextColour().
904 void SetItemTextColour(long item
, const wxColour
& col
);
907 Adds or removes a single window style.
909 void SetSingleStyle(long style
, bool add
= true);
912 Sets the text colour of the list control.
914 void SetTextColour(const wxColour
& col
);
917 Sets the whole window style, deleting all items.
919 void SetWindowStyleFlag(long style
);
922 Call this function to sort the items in the list control. Sorting is done
923 using the specified @a fnSortCallBack function. This function must have the
926 int wxCALLBACK wxListCompareFunction(long item1, long item2, wxIntPtr sortData)
929 It is called each time when the two items must be compared and should return 0
930 if the items are equal, negative value if the first item is less than the
931 second one and positive value if the first one is greater than the second one
932 (the same convention as used by @c qsort(3)).
934 The parameter @e item1 is the client data associated with the first item (NOT the index).
935 The parameter @e item2 is the client data associated with the second item (NOT the index).
936 The parameter @e data is the value passed to SortItems() itself.
938 Notice that the control may only be sorted on client data associated with
939 the items, so you must use SetItemData if you want to be able to sort the
940 items in the control.
942 Please see the @ref page_samples_listctrl for an example of using this function.
945 In wxPerl the comparison function must take just two parameters;
946 however, you may use a closure to achieve an effect similar to the
947 SortItems third parameter.
950 bool SortItems(wxListCtrlCompare fnSortCallBack
, wxIntPtr data
);
955 This function may be overridden in the derived class for a control with
956 @c wxLC_VIRTUAL style. It should return the attribute for the specified
957 @c item or @NULL to use the default appearance parameters.
959 wxListCtrl will not delete the pointer or keep a reference of it.
960 You can return the same wxListItemAttr pointer for every OnGetItemAttr() call.
962 The base class version always returns @NULL.

1001 @c wxLC_VIRTUAL style having an "image list" (see SetImageList(); if the
1002 control doesn't have an image list, it is not necessary to override it).
1003 It should return the index of the items image in the controls image list
1006 In a control with @c wxLC_REPORT style, OnGetItemImage() only gets called for
1007 the first column of each line.

1245 This class currently simply presents a simpler to use interface for the
1246 wxListCtrl -- it can be thought of as a @e façade for that complicated class.
1248 Using it is preferable to using wxListCtrl directly whenever possible because
1249 in the future some ports might implement wxListView but not the full set of
1250 wxListCtrl features.
1252 Other than different interface, this class is identical to wxListCtrl.
1253 In particular, it uses the same events, same window styles and so on.

1353 wxListItem is a class which contains informations about:
1354 - Zero based item position; see SetId() and GetId().
1355 - Zero based column index; see SetColumn() and GetColumn().
1356 - The label (or header for columns); see SetText() and GetText().
1357 - The zero based index into an image list; see GetImage() and SetImage().

1359 - For columns only: the width of the column; see SetWidth() and GetWidth().
1360 - For columns only: the format of the column; one of @c wxLIST_FORMAT_LEFT,
1361 @c wxLIST_FORMAT_RIGHT, @c wxLIST_FORMAT_CENTRE. See SetAlign() and GetAlign().
1362 - The state of the item; see SetState() and GetState().
1363 This is a bitlist of the following flags:
1364 - @c wxLIST_STATE_FOCUSED: The item has the focus.
1365 - @c wxLIST_STATE_SELECTED: The item is selected.
1366 - @c wxLIST_STATE_DONTCARE: Don't care what the state is. Win32 only.

1369 - A mask indicating which state flags are valid; this is a bitlist of the
1370 flags reported above for the item state. See SetStateMask() and GetStateMask().
1371 - A mask indicating which fields of this class are valid; see SetMask() and GetMask().
1372 This is a bitlist of the following flags:
1373 - @c wxLIST_MASK_STATE: The state field is valid.

1378 - @c wxLIST_MASK_FORMAT: The column format field is valid.
1380 The wxListItem object can also contain item-specific colour and font
1381 information: for this you need to call one of SetTextColour(), SetBackgroundColour()
1382 or SetFont() functions on it passing it the colour/font to use.
1383 If the colour/font is not specified, the default list control colour/font is used.
