RE: [wxperl-users] Help with Wx::Grid and XRC

[Kapell, J. <jk...@ti...>]

Hello,

do you have initialised the XRC handler before via 'InitAllHandlers'? I've
tried something with XRC and it works good, but not yet with wxGrid. Also I
could not work with sub classing at XRC. It seems that this isn't
implemented yet. Below you can find a short example taken from the wxPerl
examples.

Mattia: Do you have a plan when sub classing are available via XRC?

Or do anybody know, how to handle a 'virtual' list control via XRC?

Best regards 
Jens

Subject: [wxperl-users] Help with Wx::Grid and XRC


I am trying to load a dialog from XRC containing a wxGrid and I am
getting errors:

- No handler found for XML node 'object', class 'wxGrid'
- Error in resource.

Has anybody tried this?

It sounds like the 'Wx::XmlResource' object cannot handle a wxGrid
resource. Do I have to create a handler for wxGrid?

If yes, can anybody help with info on this?
