Summary: wxTreeListCtrl::GetPrev doesn't work
Initial Comment:
Hi!
I tried to use the GetPrev method of the treelistctrl and i figured out it
hasn't functioned properly at any time. It seems that it is just an
unthoughtful copy of GetNext.
I suggest to repace it with this code:
wxTreeItemId wxTreeListMainWindow::GetPrev (const wxTreeItemId& item, bool
fulltree) const {
wxCHECK_MSG (item.IsOk(), wxTreeItemId(), _T("invalid tree item"));
wxTreeItemId prev = GetPrevSibling (item);
// if is the first child, the parent is the previous one.
if (!prev.IsOk()) {
return GetItemParent(item);
}
wxTreeListItem* prevItem = (wxTreeListItem*)prev.m_pItem;
while ((fulltree || prevItem->IsExpanded()) &&
(prevItem->GetChildren().GetCount() > 0)) {
prevItem = prevItem->GetChildren().Last();
}
return wxTreeItemId(prevItem);
}
