Problem This is in response to Tropico's post titled "Finding first gtkentry widget into GtkNotebook page".
He would like to grab_focus on the first GtkEntry widget of one page of the notebook when the page becomes active as shown below:
Solution
- We make use of the technique as described in How to know which tab of GtkNotebook is being clicked on? to know when a new page is active.
- Once we know which tab the user has clicked, we can just grab focus on the GtkEntry associated with that tab.
- In this example, I have used a global variable to store the GtkEntry's. If you're using Glade, you can easily use $glade->get_widget(entry_name) to retrieve the pointer to the GtkEntry. If you're using OOP or classes, you can neatly encapsulate this as one of the members within the class.

$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());

"Part 1 - whole text in GtkEntry is selected on focus");
$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);
// setup notebook
$notebook = new GtkNotebook(); // note 1
$vbox->pack_start($notebook);
// add a vbox into each of the notebook page
for ($i=1; $i<=3; ++$i) {
// add a vbox to each page
$page_vbox[$i] = new GtkVBox();
$tab_label = "Tab $i";
add_new_tab($notebook, $page_vbox[$i], $tab_label); // note 2
$hbox = new GtkHBox();
$page_vbox[$i]->pack_start($hbox, 0);
// add the first alignment containing a label
$alignment1 = new GtkAlignment(0, 0.5, 0, 0); // note 3
$alignment1->add(new GtkLabel("Label $i: "));
$hbox->pack_start($alignment1, 0);
// add the second alignment containing a GtkEntry
$alignment2 = new GtkAlignment(0, 0.5, 0, 0); // note 4
$entry[$tab_label] = new GtkEntry(); // note 5
$alignment2->add($entry[$tab_label]);
$entry[$tab_label]->set_text("this is entry #$i");
$hbox->pack_start($alignment2, 0);
}
$window->show_all();
Gtk::main();
