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

mw
Tk window where the file structure is displayed.
H5obj

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.
