Problem
You have displayed a 2D array in a GtkSheet in How to use GtkSheet - Part 3 - set values?.
Now you would like to display the 2D array in a GtkSheet with appropriate justification as shown below:
Solution
- Make sure your version of PHP-GTK2 has the GtkExtra library, and the feature turned on in php.ini. (See notes below.)
- Create the spreadsheet as outlined in How to use GtkSheet - Part 1 - create the spreadsheet?
- Set the value of a cell with justification using
GtkSheet::set_cell($row, $col, $justification, $value)
- The
$justification
are predefined constants as listed here.
Important Note: This only works for PHP-GTK2 compliled with the additional library GtkExtra. For linux, you can download the files from http://gtkextra.sourceforge.net/ and do a recompile. For windows, you may use the builds by Elizabeth Smith or the official php-gtk2 beta release available at http://gtk.php.net/download.php. Both contain all the required gtkextra libraries and dll's. In the php.ini
, don't forget to add php-gtk.extensions = php_gtk_extra2.dll
to turn on GtkExtra.

"Part 4 - Set Values with Justification"); $title->modify_font(new PangoFontDescription("Times New Roman Italic 10")); $title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff")); $title->set_size_request(-1, 40); $title->set_justify(Gtk::JUSTIFY_CENTER); $alignment = new GtkAlignment(0.5, 0, 0, 0); $alignment->add($title); $vbox->pack_start($alignment, 0, 0); $vbox->pack_start(new GtkLabel(), 0, 0); // the 2D table $data = array( array('row0', 'item 42', 2, 3.1), array('row1', 'item 36', 20, 6.21), array('row2', 'item 21', 8, 9.36), array('row3', 'item 10', 11, 12.4), array('row4', 'item 7', 5, 15.5), array('row5', 'item 4', 17, 18.6), array('row6', 'item 3', 20, 21.73)); $justification = array('LEFT', 'LEFT', 'CENTER', 'RIGHT'); // note 1 display_table($vbox, $data, $justification); $window->show_all(); Gtk::main(); function display_table($vbox, $data, $justification) { $scrolled_win = new GtkScrolledWindow(); $scrolled_win->set_policy( Gtk::POLICY_AUTOMATIC, Gtk::POLICY_AUTOMATIC); $vbox->pack_start($scrolled_win); $sheet = new GtkSheet(count($data), count($data[0]), 'Test 123'); $sheet->set_autoresize(1); $scrolled_win->add($sheet); for ($row=0; $row<count($data); ++$row) { for ($col=0; $col<count($data[$row]); ++$col) { $justify = constant("Gtk::JUSTIFY_".$justification[$col]); $sheet->set_cell($row, $col, $justify, $data[$row][$col]); // note 2 } } } ?> |
Output
As shown above.Explanation
- The array specifying the justification for each column. In this example, we set the first two columns to be left-justified, the third column (unit price) to be center-justified, and the last (price) to be right justiftied.
- Set the value of a cell in GtkSheet.
