no built in Virtual mode.

Sure there is

wxGrid::SetTable

Use this function instead of CreateGrid() when your application involves complex or non-string data or data sets that are too large to fit wholly in memory.

The virtual class is wxGridTableBase

Perl example is  wxperl_demo --show "Custom wxGridTable"

It shows inheriting being derived from Wx::PlGridTable and Wx::PlGridTable @ISA = qw(Wx::GridTableBase);, this is the wxperl way for virtual classes as Wx::NewClass explains

http://wiki.wxperl.nl/Wx::GridTableBase mentions this

Also some related info at Software Woes: wxGrid with virtual storage and multirow or multicolumn cells

    AM, thank you for the correction. Always more to learn.

    Response to my inquiry on the wxPerl mailing list:

    Hi,

    It isn't implemented in wxWidgets - probably because the library attempts to either use the native platform controls or mimic them as closely as possible. If you cannot do it with a native control, you most likely can't do it in wxWidgets. I doubt this is seen as a missing feature so you're unlikely to see it implemented in the future.

    Wx::Grid is the way to go to do what you want.

    By the way, I noticed on Perl Monks some information regarding how Wx::ListCtrl handles a large number of items.

    For that you need to use the wxLC_VIRTUAL|wxREPORT style. See the Wx::Demo where the virtual list control reports 100,000 items.

    For a Wx::Grid control with a large number of items, you should use a custom Wx::GridTable. The example in Wx::Demo reports 100,000 columns by 100,000 rows.

    Hope it helps. Sorry no positive answer on the column formatting.

    Regards
