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

1000 columns interactively by dragging them. In this case, the index of the

1002 and GetColumnIndexFromOrder() should be used to translate between them.

1004 i.e. the visual positioning of the columns on screen doesn't affect the
1005 code setting or getting their values for example.
1006
1007 The @a orders array must have the same number elements as the number of
1008 columns and contain each position exactly once. Its n-th element
1009 contains the index of the column to be shown in n-th position, so for a

1011 results in the third column being displayed first, the first one next
1012 and the second one last.
