Problem This is in response to Neil's post titled "Get co-ordnates".
He would like to find the position (x,y co-ordinates) of an eventbox, or a label as shown below:

Solution
Note: I find that it only works when you stuff the label in an eventbox. If you just use a GtkLabel without GtkEventBox, for some reason, the value does not seem to be correct.
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
| <?php $window = new GtkWindow(); $window->set_size_request(400, 200); $window->connect_simple('destroy', array('Gtk','main_quit')); $window->add($vbox = new GtkVBox());
// display title
$title = new GtkLabel("Get the position of a label or eventbox"); $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); $vbox->pack_start(new GtkLabel(), 0, 0);
$vbox->pack_start(new GtkLabel());
$vbox->pack_start($hbox = new GtkHBox()); $hbox->pack_start(new GtkLabel()); $label = new GtkLabel('this is the label'); // note 1
$hbox->pack_start($eventbox = new GtkEventBox, 0); // note 2
$eventbox->add($label); // note 2
$eventbox->modify_bg(Gtk::STATE_NORMAL, GdkColor::parse("#aaaaaa")); $hbox->pack_start(new GtkLabel());
