3 A list control presents lists in a number of formats: list view, report view,
4 icon view and small icon view. In any case, elements are numbered from zero.
5
6 Using many of wxListCtrl is shown in the
7 \helpref{corresponding sample}{samplelistctrl}.
8
9 To intercept events from a list control, use the event table macros described
10 in \helpref{wxListEvent}{wxlistevent}.

490 \membersection{wxListCtrl::SetBackgroundColour}\label{wxlistctrlsetbackgroundcolour}
491
492 \func{void}{SetBackgroundColour}{\param{const wxColour\& }{col}}
493
494 Sets the background colour (GetBackgroundColour already implicit in
495 wxWindow class).
496
497 \membersection{wxListCtrl::SetColumn}\label{wxlistctrlsetcolumn}
498
499 \func{bool}{SetColumn}{\param{int }{col}, \param{wxListItem\& }{item}}
500
501 Sets information about this column. See \helpref{wxListCtrl::SetItem}{wxlistctrlsetitem} for more
502 information.
503
504 \membersection{wxListCtrl::SetColumnWidth}\label{wxlistctrlsetcolumnwidth}
505
506 \func{bool}{SetColumnWidth}{\param{int }{col}, \param{int }{width}}
507
508 Sets the column width.
509
510 {\it width} can be a width in pixels or wxLIST\_AUTOSIZE (-1) or wxLIST\_AUTOSIZE\_USEHEADER (-2).
511 wxLIST\_AUTOSIZE will resize the column to the length of its longest item. wxLIST\_AUTOSIZE\_USEHEADER
512 will resize the column to the length of the header (Win32) or 80 pixels (other platforms).
513
514 In small or normal icon view, {\it col} must be -1, and the column width is set for all columns.
515
516 \membersection{wxListCtrl::SetImageList}\label{wxlistctrlsetimagelist}
517
518 \func{void}{SetImageList}{\param{wxImageList*}{ imageList}, \param{int }{which}}
519
520 Sets the image list associated with the control. {\it which} is one of
521 wxIMAGE\_LIST\_NORMAL, wxIMAGE\_LIST\_SMALL, wxIMAGE\_LIST\_STATE (the last is unimplemented).

527 \func{long}{SetItem}{\param{long }{index}, \param{int }{col}, \param{const }{wxString\& label}, \param{int }{imageId = -1}}
528
529 Sets information about the item.
530
531 wxListItem is a class with the following members:
532
533 \twocolwidtha{5cm}
534 \begin{twocollist}\itemsep=0pt
535 \twocolitem{long m\_mask}{Indicates which fields are valid. See the list of valid mask flags below.}
536 \twocolitem{long m\_itemId}{The zero-based item position.}
537 \twocolitem{int m\_col}{Zero-based column, if in report mode.}
538 \twocolitem{long m\_state}{The state of the item. See the list of valid state flags below.}
539 \twocolitem{long m\_stateMask}{A mask indicating which state flags are valid. See the list of valid state flags below.}
540 \twocolitem{wxString m\_text}{The label/header text.}
541 \twocolitem{int m\_image}{The zero-based index into an image list.}
542 \twocolitem{long m\_data}{Application-defined data.}
543 \twocolitem{int m\_format}{For columns only: the format. Can be wxLIST\_FORMAT\_LEFT, wxLIST\_FORMAT\_RIGHT or
544 wxLIST\_FORMAT\_CENTRE.}
545 \twocolitem{int m\_width}{For columns only: the column width.}
546 \end{twocollist}
547
548 The {\bf m\_mask} member contains a bitlist specifying which of the other fields are valid. The flags are:
549
550 \twocolwidtha{5cm}
551 \begin{twocollist}\itemsep=0pt
552 \twocolitem{wxLIST\_MASK\_STATE}{The {\bf m\_state} field is valid.}
553 \twocolitem{wxLIST\_MASK\_TEXT}{The {\bf m\_text} field is valid.}
554 \twocolitem{wxLIST\_MASK\_IMAGE}{The {\bf m\_image} field is valid.}
555 \twocolitem{wxLIST\_MASK\_DATA}{The {\bf m\_data} field is valid.}
556 \twocolitem{wxLIST\_MASK\_WIDTH}{The {\bf m\_width} field is valid.}
557 \twocolitem{wxLIST\_MASK\_FORMAT}{The {\bf m\_format} field is valid.}
558 \end{twocollist}
559
560 The {\bf m\_stateMask} and {\bf m\_state} members take flags from the following:
561
562 The wxListItem object can also contain item-specific colour and font
563 information: for this you need to call one of SetTextColour(),
564 SetBackgroundColour() or SetFont() functions on it passing it the colour/font
565 to use. If the colour/font is not specified, the default list control
566 colour/font is used.
567
568 \twocolwidtha{5cm}
569 \begin{twocollist}\itemsep=0pt
570 \twocolitem{wxLIST\_STATE\_DONTCARE}{Don't care what the state is. Win32 only. }
571 \twocolitem{wxLIST\_STATE\_DROPHILITED}{The item is highlighted to receive a drop event. Win32 only. }
572 \twocolitem{wxLIST\_STATE\_FOCUSED}{The item has the focus.}
573 \twocolitem{wxLIST\_STATE\_SELECTED}{The item is selected.}
574 \twocolitem{wxLIST\_STATE\_CUT}{The item is in the cut state. Win32 only. }
575 \end{twocollist}
576
577 \func{long}{SetItem}{\param{long }{index}, \param{int }{col}, \param{const wxString\& }{label}, \param{int }{imageId = -1}}
578
579 Sets a string field at a particular column.
580
581 \pythonnote{In place of a single overloaded method name, wxPython
582 implements the following methods:\par
583 \indented{2cm}{\begin{twocollist}
584 \twocolitem{{\bf SetItem(item)}}{Sets information about the given wxListItem.}
585 \twocolitem{{\bf SetStringItem(index, col, label, imageId)}}{Sets a
586 string or image at a given location.}
587 \end{twocollist}}
588 }
589
590 \membersection{wxListCtrl::SetItemData}\label{wxlistctrlsetitemdata}

597
598 \func{bool}{SetItemImage}{\param{long }{item}, \param{int }{image}, \param{int }{selImage}}
599
600 Sets the unselected and selected images associated with the item. The images are indices into the
601 image list associated with the list control.
602
603 \membersection{wxListCtrl::SetItemPosition}\label{wxlistctrlsetitemposition}
604
605 \func{bool}{SetItemPosition}{\param{long }{item}, \param{const wxPoint\& }{pos}}

610
611 \func{bool}{SetItemState}{\param{long }{item}, \param{long }{state}, \param{long }{stateMask}}
612
613 Sets the item state. For a list of state flags, see \helpref{wxListCtrl::SetItem}{wxlistctrlsetitem}.
614
615 The {\bf stateMask} indicates which state flags are valid.
616
617 \membersection{wxListCtrl::SetItemText}\label{wxlistctrlsetitemtext}
618
619 \func{void}{SetItemText}{\param{long }{item}, \param{const wxString\& }{text}}
620

622
623 \membersection{wxListCtrl::SetSingleStyle}\label{wxlistctrlsetsinglestyle}
624
625 \func{void}{SetSingleStyle}{\param{long }{style}, \param{const bool }{add = TRUE}}

632
633 Sets the text colour of the list control.
634
635 \membersection{wxListCtrl::SetWindowStyleFlag}\label{wxlistctrlsetwindowstyleflag}
636
637 \func{void}{SetWindowStyleFlag}{\param{long }{style}}
638
639 Sets the whole window style.
640
641 \membersection{wxListCtrl::SortItems}\label{wxlistctrlsortitems}
642
643 \func{bool}{SortItems}{\param{wxListCtrlCompare }{fnSortCallBack}, \param{long }{data}}
644
645 Call this function to sort the items in the list control. Sorting is done
646 using the specified {\it fnSortCallBack} function. This function must have the
647 following prototype:
648
649 \begin{verbatim}
650 int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData)
651 \end{verbatim}
652
653 It is called each time when the two items must be compared and should return 0
654 if the items are equal, negative value if the first item is less than the
655 second one and positive value if the first one is greater than the second one
656 (the same convention as used by {\tt qsort(3)}).
657
658 \wxheading{Parameters}
659
660 \docparam{item1}{client data associated with the first item ({\bf NOT} the index).}
661
662 \docparam{item2}{client data associated with the second item ({\bf NOT} the index).}
663
664 \docparam{data}{the value passed to SortItems() itself.}
665
666 Notice that the control may only be sorted on client data associated with the
667 items, so you {\bf must} use \helpref{SetItemData}{wxlistctrlsetitemdata} if
668 you want to be able to sort the items in the control.
669
670 Please see the \helpref{listctrl sample}{samplelistctrl} for an example of
671 using this function.
672
673 \pythonnote{wxPython uses the sortData parameter to pass the Python
674 function to call, so it is not available for programmer use. Call
675 SortItems with a reference to a callable object that expects two
676 parameters.}
