-/*
- 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 wxWindows 2.0 event system.
-
- See the sample wxListCtrl app for API usage.
