GtkTable demoLike layout tables in HTML pages, the GtkTable widget can be used to display tables or matrix, far more easily than GtkTreeView and associated classes.

This example shows how to use a layout table and fill it with numerous instances of GtkLabel, of varying colours.

<?php
define('SIZE_X',   10);
define('SIZE_Y',   3);

# WIDGET HIERARCHY
$window = new GtkWindow();

/**
* Creating our GtkTable
* note that the homogeneous property defaults to false.
*/
$table = new GtkTable(SIZE_X, SIZE_Y, false);

# labels
for ($i = 0 ; $i < SIZE_X ; $i++) {
  for ($j = 0 ; $j < SIZE_Y ; $j++) {
    $label = new GtkLabel("$i : $j");
    $table->attach($label, $i, $i+1, $j, $j+1,
      Gtk::EXPAND, Gtk::EXPAND);
  }
}

/**
* SETTINGS
*/

// Title of the window
$window->set_title("GtkTable usage demonstration");

// Initial placement of the window
$window->set_position(Gtk::WIN_POS_CENTER);

// Connecting the "destroy" signal
$window->connect_simple('destroy', array('Gtk', 'main_quit'));

// Let's define the spacing between columns and rows to 10 pixels
$table->set_row_spacings(10);
$table->set_col_spacings(10);

/**
* ASSEMBLY
*/

// Adding the table to the window
$window->add($table);

$count = 0;
foreach ($table->get_children() as $child) {
  $count++;

  # set a random color
  if ($count %2 == 0)
    $color = 'red';
  else
   $color = 'green';

$child->modify_fg(Gtk::STATE_NORMAL,
  $label->get_colormap()->alloc_color($color));
}

// Make everything in the window visible
$window->show_all();
//Main loop
Gtk::main();
?>
