On windows use nmake or dmake instead of make.

DEPENDENCIES

The following modules are required in order to use Gtk2::Ex::Linker

        Gtk2::Ex::DbLinker::DbTools => 0.99
        DateTime::Format::Strptime => 1.5,
        Test::More => 0.44,
        Gtk2 => 1.240,
        Carp => 1.17
        Log::Log4perl => 1.41

Install one of Rose::DB::Object or DBIx::Class if you want to use these orm to access your data.

Rose::DB object is required to get example 2_rdb working. DBIx::Class is required to get example 2_dbc working.

DESCRIPTION

This module automates the process of tying data from a database to widgets on a Glade-generated form. All that is required is that you name your widgets the same as the fields in your data source.

Steps for use:

  • Create a DataManager object that contains the rows to display. Use DbiDataManager, RdbDataManager or DbcDataManager depending on how you access the database: sql commands and DBI, DBIx::Class or Rose::DB::Object

  • Create a Gtk2::GladeXML object to construct the Gtk2 windows

  • Create a Gtk2::Ex::DbLinker::Form object that links the data and the windows

  • You would then typically connect the buttons to the methods below to handle common actions such as inserting, moving, deleting, etc.

EXAMPLES

The examples folder (located in the Gtk2-Ex-DbLinker-xxx folder under cpan/build in your perl folders tree) contains four examples that use a sqlite database of three tables:

  • countries (countryid, country, mainlangid),

  • langues (langid, langue),

  • speaks (langid, countryid) in example2_dbc, file ./data/ex1_1 or (speaksid, langid, countryid) in example2_dbi and 2_rdb, file ./data/ex1

  • runexample1.pl runs at the command line, gives a form that uses DBI and sql commands to populate a drop box and a datasheet.

  • runeexample2_xxx.pl gives a main form with a bottom navigation bar that displays each record (a country and its main language) one by one.

    A subform displays other(s) language(s) spoken in that country. Each language is displayed one by one and a second navigation bar is used to show these in turn.

    For each language, a list gives the others countries where this idiom is spoken. Items from this lists are also add/delete/changed with a third navigation bar.

  • runeexample2_dbc.pl uses DBIx::Class. The speaks table primary key is the complete row itself, with the two fields, countryid and langid.

  • runeexample2_dbi.pl uses sql commands and DBI. The speaks table primary key is a counter speaksid (primary key) and the two fields, countryid and langid compose an index which does not allow duplicate rows.

  • runeexample2_rdb.pl uses Rose::Data::Object. The database is the same as example 2_dbi.
