Problem
We have displayed a 2D array in a table in Part 1. Now we would like to add borders to the table as shown below:
$data = array( array('', 'header1', 'header2', 'header3'), array('row0', 1, 2, 3), array('row1', 4, 5, 6));
Solution
- GtkTable itself does not provide built-in method such as the
<table border=1>
statement in html to add a border to each cell. - However, the GtkTable::attach() method allows us to attach almost any widget to each cell.
- As such, to draw a border, we simply put each cell inside a GtkFrame, and attach the GtkFrame to the table.
Sample Code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 26 27 28 29 31 32 34 35 36 37 38 39 40 41 42 43 | <?php $window = new GtkWindow(); $window->set_size_request(400, 200); $window->connect_simple('destroy', array('Gtk','main_quit')); $vbox = new GtkVBox(); $window->add($vbox); // display title $title = new GtkLabel('Display 2D Array in Table - Part 2 (add borders)'); $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); $table = new GtkTable(); $vbox->pack_start($table); $data = array( array('', 'header1', 'header2', 'header3'), array('row0', 1, 2, 3), array('row1', 4, 5, 6)); display_table ($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(); // note1 $frame->add(new GtkLabel($a[$row][$col])); // note 2 $table->attach($frame, $col, $col+1, $row, $row+1); // note3 } } } $window->show_all(); Gtk::main(); ?> |
Output
As shown above.Explanation
Please refer to Part 1 first which explains how to display a 2D array in a table.
What's new here in Part 2:
- Create the frame
- Put the cell content (GtkLabel) inside the frame
- Attach the frame (not the GtkLabel) to the table
