@class wxListCtrl
and attributes) is managed by the main program and is requested by the control
itself only when needed which allows to have controls with millions of items
without consuming much memory. To use virtual list control you must use
- wxListCtrl::SetItemCount first and overload at least wxListCtrl::OnGetItemText
+ wxListCtrl::SetItemCount first and override at least wxListCtrl::OnGetItemText
(and optionally wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
wxListCtrl::OnGetItemAttr) to return the information about the items when the
control requests it.
+
Virtual list control can be used as a normal one except that no operations
which can take time proportional to the number of items in the control happen
-- this is required to allow having a practically infinite number of items.
<b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native
implementation for report mode, and uses a generic implementation for other
modes. You can use the generic implementation for report mode as well by setting
- the @c mac.listctrl.always_use_generic system option (see wxSystemOption) to 1.
-
- <b>wxMSW Note</b>: In report view, the control has several columns
- which are identified by their internal indices. By default, these indices
- correspond to their order on screen, i.e. the column 0 appears first (in the
- left-to-right or maybe right-to-left if the current language uses this writing
- direction), the column 1 next and so on. However it is possible to reorder the
- columns visual order using SetColumnsOrder() method and the user can also
- rearrange the columns interactively by dragging them. In this case, the index
- of the column is not the same as its order and the functions GetColumnOrder()
- and GetColumnIndexFromOrder() should be used to translate between them.
