/**
@class wxListCtrl
A list control presents lists in a number of formats: list view, report view,
icon view and small icon view. In any case, elements are numbered from zero.
For all these modes, the items are stored in the control and must be added to
it using wxListCtrl::InsertItem method.
A special case of report view quite different from the other modes of the list
control is a virtual control in which the items data (including text, images
and attributes) is managed by the main program and is requested by the control
itself only when needed which allows to have controls with millions of items
without consuming much memory. To use virtual list control you must use
wxListCtrl::SetItemCount first and overload at least
wxListCtrl::OnGetItemText (and optionally
wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
wxListCtrl::OnGetItemAttr) to return the information
about the items when the control requests it. Virtual list control can be used
as a normal one except that no operations which can take time proportional to
the number of items in the control happen -- this is required to allow having a
practically infinite number of items. For example, in a multiple selection
virtual list control, the selections won't be sent when many items are selected
at once because this could mean iterating over all the items.
Using many of wxListCtrl features is shown in the
@ref overview_samplelistctrl "corresponding sample".
To intercept events from a list control, use the event table macros described
in wxListEvent.
@b Mac Note: Starting with 2.8, wxListCtrl uses a native implementation for
report mode, and uses a generic implementation for other modes. You can use the
generic implementation for report mode as well by setting the
mac.listctrl.always_use_generic wxSystemOption() to
1.
@beginStyleTable
@style{wxLC_LIST}
Multicolumn list view, with optional small icons. Columns are
computed automatically, i.e. you don't set columns as in
wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
@style{wxLC_REPORT}
Single or multicolumn report view, with optional header.
@style{wxLC_VIRTUAL}
The application provides items text on demand. May only be used
with wxLC_REPORT.
@style{wxLC_ICON}
Large icon view, with optional labels.
@style{wxLC_SMALL_ICON}
Small icon view, with optional labels.
@style{wxLC_ALIGN_TOP}
Icons align to the top. Win32 default, Win32 only.
@style{wxLC_ALIGN_LEFT}
Icons align to the left.
@style{wxLC_AUTOARRANGE}
Icons arrange themselves. Win32 only.
@style{wxLC_EDIT_LABELS}
Labels are editable: the application will be notified when editing
starts.
@style{wxLC_NO_HEADER}
No header in report mode.
@style{wxLC_SINGLE_SEL}
Single selection (default is multiple).
@style{wxLC_SORT_ASCENDING}
Sort in ascending order. (You must still supply a comparison callback
in wxListCtrl::SortItems.)
@style{wxLC_SORT_DESCENDING}
Sort in descending order. (You must still supply a comparison callback
in wxListCtrl::SortItems.)
@style{wxLC_HRULES}
Draws light horizontal rules between rows in report mode.
@style{wxLC_VRULES}
Draws light vertical rules between columns in report mode.

features.
