Problem You want to have a status bar at the bottom of your GtkWindow as shown below:

Solution
- Create a GtkStatusbar.
- Create a GtkVBox if necessary, and stuff the status bar as the last widget in the vbox (so that it's at the bottom).
- If you need the status bar to have a different background color or respond to events, stuff the status bar inside an GtkEventBox and then pack the eventbox into the vbox.
- To display a message, we need to first get a message id with GtkStatusbar::get_context_id(), then display the message with GtkStatusbar::push().
Sample Code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
| <?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("Window with status area"); $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('your body contents'));
// setup status area
$status = new GtkStatusbar(); // note 1
$eventbox = new GtkEventBox(); $eventbox->add($status); $vbox->pack_start($eventbox, 0, 0); // note 2
$eventbox->modify_bg(Gtk::STATE_NORMAL, GdkColor::parse('#ffff00')); // note 3

I think line #20 should be pack_end instead of pack_start.

Hi Tanes,
You're right! You can definitely use
pack_end()for line #20.In this example, the status bar is packed using
pack_start()as the last item. So the effect will be the same as usingpack_end().Thanks and Regards,

You can also use the pop function to clear the statusbar when you're done, for moving on to another field, button, etc. As in:
$status->pop($context_id);
In our app, I connect two signals to each field; one for enter_notify_event, and one for leave_notify_event, so that the statusbar always reflects the help note for wherever the user is pointing.
