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 | For all these modes, the items are stored in the control and must be added to | |
6 | it using \helpref{InsertItem}{wxlistctrlinsertitem} method. | |
7 | ||
8 | A special case of report view quite different from the other modes of the list | |
9 | control is a virtual control in which the items data (including text, images | |
10 | and attributes) is managed by the main program and is requested by the control | |
11 | itself only when needed which allows to have controls with millions of items | |
12 | without 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 | |
17 | about the items when the control requests it. Virtual list control can be used | |
18 | as a normal one except that no operations which can take time proportional to | |
19 | the number of items in the control happen -- this is required to allow having a | |
20 | practically infinite number of items. For example, in a multiple selection | |
21 | virtual list control, the selections won't be sent when many items are selected | |
22 | at once because this could mean iterating over all the items. | |
23 | ||
24 | Using many of wxListCtrl features is shown in the | |
25 | \helpref{corresponding sample}{samplelistctrl}. | |
26 | ||
27 | To intercept events from a list control, use the event table macros described | |
28 | in \helpref{wxListEvent}{wxlistevent}. | |

217 | text control will appear for in-place editing. | |
218 | ||
219 | If the user changed the label (i.e. s/he does not press ESC or leave | |
220 | the text control without changes, a EVT\_LIST\_END\_LABEL\_EDIT event | |

704 | The wxListItem object can also contain item-specific colour and font | |
705 | information: for this you need to call one of SetTextColour(), | |

733 | ||
734 | \func{void}{SetItemCount}{\param{long }{count}} | |
735 | ||
736 | This method can only be used with virtual list controls. It is used to indicate | |
737 | to the control the number of items it contains. After calling it, the main | |
738 | program should be ready to handle calls to various item callbacks (such as | |

795 | \func{bool}{SortItems}{\param{wxListCtrlCompare }{fnSortCallBack}, \param{long }{data}} | |
796 | ||
797 | Call this function to sort the items in the list control. Sorting is done | |
798 | using the specified {\it fnSortCallBack} function. This function must have the | |
799 | following prototype: | |
800 | ||
801 | \begin{verbatim} | |
802 | int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData) | |
803 | \end{verbatim} | |
804 | ||
805 | It is called each time when the two items must be compared and should return 0 | |
806 | if the items are equal, negative value if the first item is less than the | |
807 | second one and positive value if the first one is greater than the second one | |
808 | (the same convention as used by {\tt qsort(3)}). | |

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 | ||
818 | Notice that the control may only be sorted on client data associated with the | |
819 | items, so you {\bf must} use \helpref{SetItemData}{wxlistctrlsetitemdata} if | |
820 | you want to be able to sort the items in the control. | |
821 | ||
822 | Please see the \helpref{listctrl sample}{samplelistctrl} for an example of | |
823 | using this function. | |
824 | ||
825 | \pythonnote{wxPython uses the sortData parameter to pass the Python | |
826 | function to call, so it is not available for programmer use. Call | |
827 | SortItems with a reference to a callable object that expects two | |
828 | parameters.} | |
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.} | |
