127 @class wxListCtrl
128
129 A list control presents lists in a number of formats: list view, report view,
130 icon view and small icon view. In any case, elements are numbered from zero.
131 For all these modes, the items are stored in the control and must be added to
132 it using wxListCtrl::InsertItem method.
133
134 A special case of report view quite different from the other modes of the list
135 control is a virtual control in which the items data (including text, images
136 and attributes) is managed by the main program and is requested by the control
137 itself only when needed which allows to have controls with millions of items
138 without consuming much memory. To use virtual list control you must use
139 wxListCtrl::SetItemCount first and override at least wxListCtrl::OnGetItemText
140 (and optionally wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
141 wxListCtrl::OnGetItemAttr) to return the information about the items when the
142 control requests it.
143
144 Virtual list control can be used as a normal one except that no operations
145 which can take time proportional to the number of items in the control happen
146 -- this is required to allow having a practically infinite number of items.
147 For example, in a multiple selection virtual list control, the selections won't
148 be sent when many items are selected at once because this could mean iterating
149 over all the items.
150
151 Using many of wxListCtrl features is shown in the
152 @ref page_samples_listctrl "corresponding sample".
153
154 To intercept events from a list control, use the event table macros described
155 in wxListEvent.
156
157 <b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native
158 implementation for report mode, and uses a generic implementation for other
159 modes. You can use the generic implementation for report mode as well by setting
160 the @c mac.listctrl.always_use_generic system option (see wxSystemOptions) to 1.
161
162
163 @beginStyleTable
164 @style{wxLC_LIST}
165 Multicolumn list view, with optional small icons. Columns are
166 computed automatically, i.e. you don't set columns as in
167 @c wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
168 @style{wxLC_REPORT}
169 Single or multicolumn report view, with optional header.
170 @style{wxLC_VIRTUAL}
171 The application provides items text on demand. May only be used
172 with @c wxLC_REPORT.
173 @style{wxLC_ICON}
174 Large icon view, with optional labels.
175 @style{wxLC_SMALL_ICON}
176 Small icon view, with optional labels.
177 @style{wxLC_ALIGN_TOP}
178 Icons align to the top. Win32 default, Win32 only.
179 @style{wxLC_ALIGN_LEFT}
180 Icons align to the left.
181 @style{wxLC_AUTOARRANGE}
182 Icons arrange themselves. Win32 only.
183 @style{wxLC_EDIT_LABELS}
184 Labels are editable: the application will be notified when editing
185 starts.
186 @style{wxLC_NO_HEADER}
187 No header in report mode.
188 @style{wxLC_SINGLE_SEL}
189 Single selection (default is multiple).
190 @style{wxLC_SORT_ASCENDING}
191 Sort in ascending order. (You must still supply a comparison callback
192 in wxListCtrl::SortItems.)
193 @style{wxLC_SORT_DESCENDING}
194 Sort in descending order. (You must still supply a comparison callback
195 in wxListCtrl::SortItems.)
196 @style{wxLC_HRULES}
197 Draws light horizontal rules between rows in report mode.
198 @style{wxLC_VRULES}
199 Draws light vertical rules between columns in report mode.

944 By default, the columns of a list control appear on the screen in order
945 of their indices, i.e. the column 0 appears first, the column 1 next
946 and so on. However by using this function it is possible to arbitrarily
947 reorder the columns visual order and the user can also rearrange the
948 columns interactively by dragging them. In this case, the index of the
949 column is not the same as its order and the functions GetColumnOrder()
950 and GetColumnIndexFromOrder() should be used to translate between them.
951 Notice that all the other functions still work with the column indices,
952 i.e. the visual positioning of the columns on screen doesn't affect the
953 code setting or getting their values for example.
954
955 The @a orders array must have the same number elements as the number of
956 columns and contain each position exactly once. Its n-th element
957 contains the index of the column to be shown in n-th position, so for a
958 control with three columns passing an array with elements 2, 0 and 1
959 results in the third column being displayed first, the first one next
960 and the second one last.
961

963 @code
964 wxListCtrl *list = new wxListCtrl(...);
965 for ( int i = 0; i < 3; i++ )
966 list->InsertColumn(i, wxString::Format("Column %d", i));

969 order[0] = 2;
970 order[1] = 0;

974 // now list->GetColumnsOrder() will return order and
