Also have seen that bug. if no columns are added in Columns collection, addition of new item via Items.Add cause List index out of bounds error. |

Извените я немного неправильно описал проблему, ошибка в ListItems при добавлении. Я немного проследил откуда появляется ошибка и нашел ее тут: Sorry I was a little wrong to describe the problem, the error in ListItems in the appendix. I watched from a little error and found it here: Unit listitems.inc procedure TListItems.AddItem(AItem: TListItem); begin FCacheIndex := FItems.Add(AItem); FCacheItem := AItem; if WSUpdateAllowed then WSCreateCacheItem; //Here error //Notify parent TListView that something was added. if FOwner <> nil then FOwner.ItemInserted(AItem); end; |

win32wscustomlistview.inc , line 681 in procedure class procedure TWin32WSCustomListView.ItemSetText() ............ if ALV.Column[ASubIndex].AutoSize and (TCustomListViewAccess(ALV).GetUpdateCount = 0) then ListView_SetColumnWidth(ALV.Handle, ASubIndex, AutoSizeWidth); ALV.Column[ASubIndex] raises EListError when the ListView has no columns defined Adding at least one column to ListView eliminates the problem. IMO - this is error - referencing columns without checking if there are some. List views can be used without columns to display list of icons with text (vsIcon mode). |

Yes, after your description of the problem has been resolved, thanks a lot! This would avoid the errors in my project until the developers Lazarus solve the problem. Да, после вашего описания ошибка исчезла, спасибо больше! Это позволит избежать ошибок в моем проекте пока разработчики лазаруса решат проблему. |
