Problem
The GtkDialog constructor example in the offical PHP-GTK2 documentation shows only how to get a yes/no response using a dialog box.
Suppose you would like to get inputs from user using textentry in a dialog box as shown below:
Solution
- The concept is very similar to the example How to setup a dialog box - Part 4 - non integer response id? You may want to refer to that example.
- Set up the buttons manually as outlined in the article How to setup a dialog box - Part 3 - set up buttons manually?
- In the button click event handler, we destroy the dialog manually with GtkObject::destroy().
- Although the dialog is destroyed, the variable
$phone
is still there, and we can still access the value with GtkEntry::get_text()
Sample Code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 38 39 40 41 42 43 44 45 46 47 48 49 50 51 53 54 55 56 57 59 60 61 62 63 64 65 66 67 69 70 71 72 | <?php $window = new GtkWindow(); $window->set_title($argv[0]); $window->set_size_request(400, 120); $window->connect_simple('destroy', array('Gtk','main_quit')); $window->add($vbox = new GtkVBox()); // display title $title = new GtkLabel("Set up Dialog Box - Part 5\n". "Getting text entry from a dialog box"); $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); $title->set_justify(Gtk::JUSTIFY_CENTER); $alignment = new GtkAlignment(0.5, 0, 0, 0); $alignment->add($title); $vbox->pack_start($alignment, 0, 0); $vbox->pack_start(new GtkLabel(), 0, 0); $vbox->pack_start($hbox = new GtkHBox(), 0); $hbox->pack_start(new GtkLabel('Phone Number: '), 0); $hbox->pack_start($response = new GtkLabel(), 0); $hbox->pack_start($button = new GtkButton('Enter Phone Number'), 0); $button->connect('clicked', 'on_click'); $window->show_all(); Gtk::main(); function on_click() { setup_yes_no_dialog(); } function setup_yes_no_dialog() { $dialog = new GtkDialog(); $dialog->vbox->pack_start($hbox = new GtkHBox()); $hbox->pack_start(new GtkLabel('Phone Number: '), 0); $hbox->pack_start($phone = new GtkEntry(), 0); // note 1 $dialog->vbox->pack_start($hbox2 = new GtkHBox()); $button_ok = GtkButton::new_from_stock(Gtk::STOCK_OK); $button_ok->set_size_request(87, 33); $hbox2->pack_start(new GtkLabel()); $hbox2->pack_start($button_ok, 0); $phone->connect('activate', 'on_enter', $button_ok); // note 2 $button_ok->connect('clicked', 'on_ok_button', $dialog); $dialog->set_has_separator(false); $dialog->action_area->set_size_request(-1, 1); $dialog->show_all(); $dialog->run(); $dialog->destroy(); global $response; $response->set_text($phone->get_text()); } function on_ok_button($button, $dialog) { // note 3 $dialog->destroy(); } function on_enter($entry, $button) { $button->clicked(); // note 4 } ?> |
Output
As shown above.Explanation
We make use of the code from How to setup a dialog box - Part 4 - non integer response id? to manually set up the Yes/No buttons.
What's new here:
- Create a new gtkentry for phone number.
- Register the signal "activate" so that we know whne user presses Enter.
- Destroy the dialog.
- If the user presses Enter, we simulate a mouse click on the button.
- Echo the content of the GtkEntry.
