wxPerl Object Store

jmlynesjr has asked for the wisdom of the Perl Monks concerning the following question:

Greetings:

I'm currently playing with wxTreeCtrl and I'm at the point of wanting to be able to save and retrieve the Tree. I've looked at Storable and have tried my $info = Storable::nstore($self->{TREE}, $path).A file is being created, but only contains 25 bytes.

Anyone have any ideas on doing this? In the mean time, I'm looking at stringifying the Tree and storing it myself.

See Storable where it talks about serialization ... Then see Wx::Perl::TreeView::SimpleModel which Storable should be able to serialize readily Then if you want to write a sub Wx::TreeCtrl::STORABLE_freeze and sub Wx::TreeCtrl::STORABLE_thaw see wxTreeCtrl::GetRootItem http://docs.wxwidgets.org/2.8.12/wx_wxtreectrl.html#wxtreectrlgetfirstchild http://docs.wxwidgets.org/2.8.12/wx_wxtreectrl.html#wxtreectrlgetnextchild http://docs.wxwidgets.org/2.8.12/wx_wxtreectrl.html#wxtreectrlgetnextsibling wxPPIxregexplain.pl	[reply]

Thanks for the references. I need to reread Storable in more detail. I'm familier with the wxTreeCtrl methods which I will need to use to roll my own Store. I'm working on that now. I was hoping someone had already solved this problem. But, it will be a good learning experience anyway. James There's never enough time to do it right, but always enough time to do it over...

Show us some code, for starters. As an aside, I couldn't help but notice the quote in the OP: "There's never enough time to do it right, but always enough time to do it over..." Why does it seem that all too many proponents of Agile think that is an acceptable way to do things?!? You must always remember that the primary goal is to *drain the swamp* even when you are hip-deep in alligators.	[reply]

The quote comes from years of working in a small technical area within a giant non-technical company. This company would announce fixed opening dates four years in advance, then allow physical construction to eat up all the slack time allocated for systems installation and integration while constantly changing specifications. Besides months of 16 hour days, 7 days a week by the software group, several very public failures resulted in adding back months to the schedule and adding millions back to the budget. Management never listened until the missed opening made their sponsors look bad to the public. Thus arose one of our favorite sayings.
