Gtk2::Ex::TreeMaker::FlatInterface - This module is not to be used directly. It is called from Gtk2::Ex::TreeMaker as a utility module.
This module contains a utility method sub flat_to_tree. This utility method will accept an array of arrays (a set of relational records) as its input and then return a treelike data structure that is in-turn used by the Gtk2::Ex::TreeMaker to spin the Gtk2::TreeModel.
sub flat_to_tree
Accepts no arguments. Just returns a reference to the object
Accepts an array of arrays (a set of relational records) as its input. Returns a special tree-like data structure that is then used by the Gtk2::Ex::TreeMaker to spin the Gtk2::TreeModel.
Here is a sample input:
my $recordset = [ ['Texas','Dallas','Fruits','Dec-2003','300',0,1,'red'], ['Texas','Dallas','Veggies','Jan-2004','120',1,0,'blue'], ['Texas','Austin','Fruits','Nov-2003','310',1,1,'white'], ];
Here is the corresponding output:
my $output = { 'Node' => [ { 'Node' => [ { 'Node' => [ { 'Node' => [ { 'text' => '310', 'editable' => 1, 'background' => 'white', 'hyperlinked' => 1, 'Name' => 'Nov-2003' } ], 'Name' => 'Fruits' } ], 'Name' => 'Austin' }, { 'Node' => [ { 'Node' => [ { 'text' => '120', 'editable' => 1, 'background' => 'blue', 'hyperlinked' => 0, 'Name' => 'Jan-2004' } ], 'Name' => 'Veggies' }, { 'Node' => [ { 'text' => '300', 'editable' => 0, 'background' => 'red', 'hyperlinked' => 1, 'Name' => 'Dec-2003' } ], 'Name' => 'Fruits' } ], 'Name' => 'Dallas' } ], 'Name' => 'Texas' } ], 'Name' => 'ROOT' };
This data structure is really the key input into the Gtk2::Ex::TreeMaker module. If you can provide this data structure through external means, then we can build Gtk2::Ex::TreeMaker using that. More on this later...
