示例1: wxListCtrlGetItemTextColumn
// Find the text of the list control item at the given column
wxString wxListCtrlGetItemTextColumn(wxListCtrl& listCtrl, long item, int col)
{
wxListItem listItem;
listItem.m_mask = wxLIST_MASK_TEXT;
listItem.m_itemId = item;
listItem.m_col = col;
if (listCtrl.GetItem(listItem))
return listItem.m_text;
else
return wxEmptyString;
}示例2: ConvertViewCtrlToTrackData
void ConvertViewCtrlToTrackData(const wxListCtrl &listctrl, const std::map< wxString, long > &mapping, std::vector<lfmt::TrackData> &tracklist, wxDateTime offset)
{
auto row_count = listctrl.GetItemCount();
if (row_count < 1)
return;
// grab column indices from string-long-map which we have just for purpose of dynamic indices (ie. changing column order is easy)
auto idx_artist = mapping.find("Artist")->second;
auto idx_tname = mapping.find("Trackname")->second;
auto idx_album = mapping.find("Album")->second;
auto idx_time = mapping.find("Time")->second;

// last track on the list is the most recentry track that was listened to;
// moving up the list successive tracks will get earlier times
for (int row = row_count-1; row >= 0; --row)
{
lfmt::TrackData td;
// is there a better way of getting the info out of the listviewctrl?
// it's questionable if I would have gotten it without the wxforum :(

// defaults to 3 minutes if we don't know the track's length
