Gnome Gtk3 - Widget toolkit for graphical interfaces

Description

The purpose of this project is to create an interface to the GTK+ version 3 library.

History

There is already a bit of history for this package. It started off building the GTK::Glade package which soon became too big. So a part was separated into GTK::V3. After some working with the library I felt that the class names were a bit too long and that the words gtk and gdk were repeated too many times in the class path. E.g. there was GTK::V3::Gtk::GtkButton and GTK::V3::Gdk::GdkScreen to name a few. So, finally it was split into several other packages named, Gnome::N for the native linkup on behalf of any other Gnome module, Gnome::Glib, Gnome::GObject, Gnome::Gdk3 and Gnome::Gtk3 according to what is shown on the developers page here. The classes in these packages are now renamed into e.g. Gnome::Gtk3::Button, Gnome::Gdk3::Screen, Gnome::GObject::Object and Gnome::Glib::List. As a side effect the package GTK::Glade is also renamed into Gnome::Glade3 to show that it is from Gnome and that it is based on Gtk version 3.

Example

This example does the same as the example from GTK::Simple to show you the differences between the implementations. What immediately is clear is that this example is somewhat longer. To sum up;

Pros

Cons

A screenshot of the example -this screenshot-. The code can be found at examples/01-hello-world.pl6.

use v6;

use Gnome::Gtk3::Main;
use Gnome::Gtk3::Window;
use Gnome::Gtk3::Grid;
use Gnome::Gtk3::Button;

# Instantiate main module for UI control
my Gnome::Gtk3::Main $m .= new;

# Class to handle signals
class AppSignalHandlers {

  # Handle 'Hello World' button click
  method first-button-click ( :widget($b1), :other-button($b2) ) {
    $b1.set-sensitive(False);
    $b2.set-sensitive(True);
  }

  # Handle 'Goodbye' button click
  method second-button-click ( ) {
    $m.gtk-main-quit;
  }

  # Handle window managers 'close app' button
  method exit-program ( ) {
    $m.gtk-main-quit;
  }
}

# Create a top level window and set a title
my Gnome::Gtk3::Window $top-window .= new(:empty);
$top-window.set-title('Hello GTK!');
$top-window.set-border-width(20);

# Create a grid and add it to the window
my Gnome::Gtk3::Grid $grid .= new(:empty);
$top-window.gtk-container-add($grid);

# Create buttons and disable the second one
my Gnome::Gtk3::Button $button .= new(:label('Hello World'));
my Gnome::Gtk3::Button $second .= new(:label('Goodbye'));
$second.set-sensitive(False);

# Add buttons to the grid
$grid.gtk-grid-attach( $button, 0, 0, 1, 1);
$grid.gtk-grid-attach( $second, 0, 1, 1, 1);

# Instantiate the event handler class and register signals
my AppSignalHandlers $ash .= new;
$button.register-signal(
  $ash, 'first-button-click', 'clicked',  :other-button($second)
);
$second.register-signal( $ash, 'second-button-click', 'clicked');

$top-window.register-signal( $ash, 'exit-program', 'destroy');

# Show everything and activate all
$top-window.show-all;

$m.gtk-main;

Installation

There are several crossing dependencies from one package to the other because it was one package in the past. To get all packages, just install the Gnome::Gtk3 package and the rest will be installed with it.

zef install Gnome::Gtk3
