PDL::IO::HDF5::tkview.3pm

NAME

PDL::IO::HDF5::tkview - View HDF5 files using perl/tk and PDL::IO::HDF5 modules

DESCRIPTION

This is a experimental object to view HDF5 files the PDL::IO::HDF5 module. The HDF files are displayed in a tree structure using Tk::Tree

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

mw

Tk window where the file structure is displayed.

H5obj

PDL::IO::HDF5 Object

hl

Tk Hlist object

dataDisplaySub

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.
