SYNOPSIS

 use Tk;
 use PDL::IO::HDF5::tkview
 use PDL::IO::HDF5;
 my $mw = MainWindow->new;
 
 my $h5 = new PDL::IO::HDF5('datafile.h5');  # open HDF5 file object
 my $tkview = new PDL::IO::HDF5::tkview( $mw, $h5);
 
 MainLoop;

MEMBER DATA

Tk window where the file structure is displayed.
PDL::IO::HDF5 Object

Sub ref to execute when a dataset is double-clicked. This defaults to a print of the dataset. See dataDisplaySubSet for details.

Tk Hlist object

METHODS

new

PDL::IO::HDF5::tkview Constructor - creates new object

Usage:

 $tkview = new PDL::IO::HDF5::tkview( $mw, $H5obj);
 
    Where:
        $mw     Tk window 
        $H5obj  PDL::IO::HDF5::Object

dataDisplaySubSet

Set the dataDisplaySub data member.

Usage:

 # Data Display sub to call when a dataset is double-clicked
 my $dataDisplay = sub{ my $data = $_[0]; print "I'm Displaying This $data\n";};
 $tkview->dataDisplaySubSet($dataDisplay);

The dataDisplaySub data member is a perl sub ref that is called when a dataset is double-clicked. This data member is initially set to just print the dataset's data to the command line. Using the dataDisplaySubSet method, different actions for displaying the data can be "plugged-in".

activateCmd

Internal Display method invoked whenever a tree element is activated (i.e. double-clicked). This method does nothing unless a dataset element has been selected. It that cases it calls $self->dataDisplaySub with the data.
