Hi,
Sorry to be a pain about this but I want to get it right.
I am using the following in my Wx::TreeListCtrl.pm:
use Exporter;
use base qw( Exporter);
use vars qw( $VERSION @EXPORT_OK );
@EXPORT_OK = qw( wxTR_VRULE wxTR_SHOW_ROOT_LABEL_ONLY );
But when I try and use these in my script sample1.pl I get the following
error:
Undefined subroutine &Wx::TreeListCtrl::wxTR_VRULE called ...
So if I create the functions as below, where I get the values from the
treelistctrl.h file.
sub wxTR_VRULE { 0x8000 }
sub wxTR_SHOW_ROOT_LABEL_ONLY { 0x0002 }
Is this the way to do this? Or is there a easier/better way where I can
automatically export these constants.
I do not know if I can use the tl_constants.cpp method or what else I need
to do ?
I have removed Wx::Mini. The reason I first used it was because I was
getting errors with wx_boot, but now the problems have gone, even when I
remove the 'use Wx::Mini'.
How can I increment $VERSION? The moment I change it to 0.02 in my
TreeListCtrl.pm file I get an error on Wx::wx_boot as below. I tried to
re-compile the XS files but still the error???
Wx::TreeListCtrl object version 0.01 does not match bootstrap parameter 0.02
at
C:/Perl/lib/XSLoader.pm line 92.
Thanks
Mark

There is no magic: you inherit from Exporter and set up @EXPORT_OK (and
%EXPORT_TAGS, if you need). In wxPerl the inheritance is in Wx.pm and the
EXPORT_XXX setup in Wx::Wx_Exp (which is autogenerated, but this does not
change anything).
Then there is xx_constants.cpp, which defines a function for mapping names
into constants and a wxPlConstants object to register it with the main
wxPerl AUTOLOAD sub, but the error you see is caused by incorrect use of
Exporter: in the package you do not populate EXPORT_OK and do not inherit
from Exporter.
Oh, and please do not use Wx::Mini: it is an implementation detail.
