2
3A list control presents lists in a number of formats: list view, report view,
4icon view and small icon view. In any case, elements are numbered from zero.
5For all these modes, the items are stored in the control and must be added to
6it using \helpref{InsertItem}{wxlistctrlinsertitem} method.
7
8A special case of report view quite different from the other modes of the list
9control is a virtual control in which the items data (including text, images
10and attributes) is managed by the main program and is requested by the control
11itself only when needed which allows to have controls with millions of items
12without consuming much memory. To use virtual list control you must use
13\helpref{SetItemCount}{wxlistctrlsetitemcount} first and overload at least
14\helpref{OnGetItemText}{wxlistctrlongetitemtext} (and optionally
15\helpref{OnGetItemImage}{wxlistctrlongetitemimage} and
16\helpref{OnGetItemAttr}{wxlistctrlongetitemattr}) to return the information
17about the items when the control requests it. Virtual list control can be used
18as a normal one except that no operations which can take time proportional to
19the number of items in the control happen -- this is required to allow having a
20practically infinite number of items. For example, in a multiple selection
21virtual list control, the selections won't be sent when many items are selected
22at once because this could mean iterating over all the items.
23
24Using many of wxListCtrl features is shown in the
25\helpref{corresponding sample}{samplelistctrl}.
26
27To intercept events from a list control, use the event table macros described
28in \helpref{wxListEvent}{wxlistevent}.

672
673wxListItem is a class with the following members:
674
675\twocolwidtha{5cm}
676\begin{twocollist}\itemsep=0pt
677\twocolitem{long m\_mask}{Indicates which fields are valid. See the list of valid mask flags below.}

682\twocolitem{wxString m\_text}{The label/header text.}
683\twocolitem{int m\_image}{The zero-based index into an image list.}
684\twocolitem{long m\_data}{Application-defined data.}
685\twocolitem{int m\_format}{For columns only: the format. Can be wxLIST\_FORMAT\_LEFT, wxLIST\_FORMAT\_RIGHT or
686wxLIST\_FORMAT\_CENTRE.}
687\twocolitem{int m\_width}{For columns only: the column width.}
688\end{twocollist}
689
690The {\bf m\_mask} member contains a bitlist specifying which of the other fields are valid. The flags are:
691
692\twocolwidtha{5cm}
693\begin{twocollist}\itemsep=0pt
694\twocolitem{wxLIST\_MASK\_STATE}{The {\bf m\_state} field is valid.}

699\twocolitem{wxLIST\_MASK\_FORMAT}{The {\bf m\_format} field is valid.}
700\end{twocollist}
701
702The {\bf m\_stateMask} and {\bf m\_state} members take flags from the following:
703
704The wxListItem object can also contain item-specific colour and font
705information: for this you need to call one of SetTextColour(),
706SetBackgroundColour() or SetFont() functions on it passing it the colour/font
707to use. If the colour/font is not specified, the default list control
708colour/font is used.

733
734\func{void}{SetItemCount}{\param{long }{count}}
735
736This method can only be used with virtual list controls. It is used to indicate
737to the control the number of items it contains. After calling it, the main
738program should be ready to handle calls to various item callbacks (such as
739\helpref{OnGetItemText}{wxlistctrlongetitemtext}) for all items in the range
740from $0$ to {\it count}.
741
742\membersection{wxListCtrl::SetItemData}\label{wxlistctrlsetitemdata}
743
744\func{bool}{SetItemData}{\param{long }{item}, \param{long }{data}}
745
746Associates application-defined data with this item.

749
750\func{bool}{SetItemImage}{\param{long }{item}, \param{int }{image}, \param{int }{selImage}}
751
752Sets the unselected and selected images associated with the item. The images are indices into the
753image list associated with the list control.

756
757\func{bool}{SetItemPosition}{\param{long }{item}, \param{const wxPoint\& }{pos}}
758
759Sets the position of the item, in icon or small icon view.

762
763\func{bool}{SetItemState}{\param{long }{item}, \param{long }{state}, \param{long }{stateMask}}
764
765Sets the item state. For a list of state flags, see \helpref{wxListCtrl::SetItem}{wxlistctrlsetitem}.
766
767The {\bf stateMask} indicates which state flags are valid.
768
769\membersection{wxListCtrl::SetItemText}\label{wxlistctrlsetitemtext}
770
771\func{void}{SetItemText}{\param{long }{item}, \param{const wxString\& }{text}}

776
777\func{void}{SetSingleStyle}{\param{long }{style}, \param{const bool }{add = TRUE}}

780
781\membersection{wxListCtrl::SetTextColour}\label{wxlistctrlsettextcolour}
782
783\func{void}{SetTextColour}{\param{const wxColour\& }{col}}
784

787\membersection{wxListCtrl::SetWindowStyleFlag}\label{wxlistctrlsetwindowstyleflag}
788
789\func{void}{SetWindowStyleFlag}{\param{long }{style}}
790
791Sets the whole window style.
792
793\membersection{wxListCtrl::SortItems}\label{wxlistctrlsortitems}
794
795\func{bool}{SortItems}{\param{wxListCtrlCompare }{fnSortCallBack}, \param{long }{data}}
796
797Call this function to sort the items in the list control. Sorting is done
798using the specified {\it fnSortCallBack} function. This function must have the
799following prototype:
800
801\begin{verbatim}
802int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData)
803\end{verbatim}
804
805It is called each time when the two items must be compared and should return 0
806if the items are equal, negative value if the first item is less than the
807second one and positive value if the first one is greater than the second one
808(the same convention as used by {\tt qsort(3)}).
809
810\wxheading{Parameters}
811
812\docparam{item1}{client data associated with the first item ({\bf NOT} the index).}
813
814\docparam{item2}{client data associated with the second item ({\bf NOT} the index).}
815
816\docparam{data}{the value passed to SortItems() itself.}
817
818Notice that the control may only be sorted on client data associated with the
819items, so you {\bf must} use \helpref{SetItemData}{wxlistctrlsetitemdata} if
820you want to be able to sort the items in the control.
821
822Please see the \helpref{listctrl sample}{samplelistctrl} for an example of
823using this function.
824
825\pythonnote{wxPython uses the sortData parameter to pass the Python
826function to call, so it is not available for programmer use. Call
827SortItems with a reference to a callable object that expects two
828parameters.}
829
830\perlnote{In wxPerl the comparison function must take just two parameters;
831 however, you may use a closure to achieve an effect similar to the
832 SortItems third parameter.}
