As with many other programming languages, let start with this simple yet complete "hello world!" PHP-GTK2 example as shown below:

How to get started?


Do take some time to understand this simple yet complete "hello world!" PHP-GTK2 script.

Once you understand this script, you are on your way to picking up other widgets one by one and add onto this script.

Sample Code
$window = new GtkWindow();
$window->connect_simple('destroy', array('Gtk','main_quit'));
$label = new GtkLabel("hello world!");

  1. new GtkWindow() creates a new window.
  2. connect('destroy', array('Gtk','main_quit')) ensures a clean exit when you close the window. This basically says call Gtk::main_quit() when the user close the window.
  3. new GtkLabel("hello world!") creates the text string as label.
  4. And we use $window->add to place the label in the window.
  5. $window->show_all() shows the window and all its contents.
  6. Gtk::main() - GTK takes over and starts waiting for events (e.g. mouse or keyboard input).
