Problem
We have displayed a 2D array in a table with frames and borders in How to display a 2D array in table - Part 5?
Now we would like to display the table headers using vertical text as shown below:
Solution
- First set up the table with frames and borders as described in How to display a 2D array in table - Part 5?.
- Rotate the table header with GtkLabel::set_angle().
Sample Code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 36 37 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 | <?php $window = new GtkWindow(); $window->set_size_request(400, 230); $window->connect_simple('destroy', array('Gtk','main_quit')); $window->add($vbox = new GtkVBox()); // display title $title = new GtkLabel("Display vertical text in table"); $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); $vbox->pack_start($title, 0, 0); $gap = new GtkHBox(); $gap->set_size_request(-1, 10); // add a small gap btw title and table $vbox->pack_start($gap, 0, 0); $vbox->pack_start($hbox = new GtkHBox()); $hbox->pack_start(new GtkHBox()); $hbox->pack_start($table = new GtkTable(), 0, 0); $hbox->pack_start(new GtkHBox()); $data = array( array('', ' header1 ', ' header2 ', ' header3 '), array('row0', 1, 2, 3), array('row1', 4, 5, 6), array('row2', 7, 8, 9), array('row3', 10, 11, 12), array('row4', 13, 14, 15)); display_table ($table, $data); function display_table($table, $a) { for ($row=0; $row<count($a); ++$row) { for ($col=0; $col<count($a[$row]); ++$col) { $frame = new GtkFrame(); $eventbox = new GtkEventBox(); $frame->add($eventbox); $label = new GtkLabel($a[$row][$col]); $eventbox->add($label); if ($row==0) { $label->set_angle(90); // note 1 $eventbox->modify_bg(Gtk::STATE_NORMAL, GdkColor::parse("#FFCC66")); } elseif ($row%2==0) { $eventbox->modify_bg(Gtk::STATE_NORMAL, GdkColor::parse("#CCFF99")); } if (!($row==0 && $col==0)) $table->attach($frame, $col, $col+1, $row, $row+1, Gtk::FILL, Gtk::SHRINK, 0, 0); } } } $window->show_all(); Gtk::main(); ?> |
Output
As shown above.Explanation
We make use of the code in How to display a 2D array in table - Part 5?
What's new here:
- Change the label to vertical text by rotating it 90 degree.
