|
|
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, or using virtual
|
|
functions in wxWindows 1.66.
|
|
|
|
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.
|
|
- in Win95, you can be called back to supply other information
|
|
besides text, such as state information. This saves no memory
|
|
and is probably superfluous to requirements.
|
|
- testing of whole API, extending current sample.
