/*
The wxListCtrl can show lists of items in four different modes:
wxLC_LIST: multicolumn list view, with optional small icons (icons could be
optional for some platforms). Columns are computed automatically,
i.e. you don't set columns as in wxLC_REPORT. In other words,
the list wraps, unlike a wxListBox.
wxLC_REPORT: single or multicolumn report view (with optional header)
wxLC_ICON: large icon view, with optional labels
wxLC_SMALL_ICON: small icon view, with optional labels
You can change the style dynamically, either with SetSingleStyle or
SetWindowStyleFlag.
Further window styles:
wxLC_ALIGN_TOP icons align to the top (default)
wxLC_ALIGN_LEFT icons align to the left
wxLC_AUTOARRANGE icons arrange themselves
wxLC_USER_TEXT the app provides label text on demand, except for column headers
wxLC_EDIT_LABELS labels are editable: app will be notified.
wxLC_NO_HEADER no header in report mode
wxLC_NO_SORT_HEADER can't click on header
wxLC_SINGLE_SEL single selection
wxLC_SORT_ASCENDING sort ascending (must still supply a comparison callback in SortItems)
wxLC_SORT_DESCENDING sort descending (ditto)
Items are referred to by their index (position in the list starting from zero).
Label text is supplied via insertion/setting functions and is stored by the
control, unless the wxLC_USER_TEXT style has been specified, in which case
the app will be notified when text is required (see sample).
Images are dealt with by (optionally) associating 3 image lists with the control.
Zero-based indexes into these image lists indicate which image is to be used for
which item. Each image in an image list can contain a mask, and can be made out
of either a bitmap, two bitmaps or an icon. See ImagList.h for more details.
Notifications are passed via the event system.
See the sample wxListCtrl app for API usage.
TODO:
- addition of further convenience functions
to avoid use of wxListItem in some functions
- state/overlay images: probably not needed.
- testing of whole API, extending current sample.
