GTK::Simple

GTK::Simple is a set of simple GTK 3 bindings using NativeCall. Only a few GTK widgets are currently implemented. However, these are enough to create a reasonable interactive GUI for an idiomatic Raku program. Widgets are gradually being added. These include the following:

Widget	Description
Button	A simple button with a label and a callback
ComboBoxText	A simple combo box
Entry	Allows for text to be provided by the user
FileChooserButton	A button that opens a file chooser dialog
Frame	A bin with a decorative frame and optional label
Grid	A table-like container for widgets for window design
Label	Adds a line of text
LevelBar	A bar that can used as a level indicator
LinkButton	Create buttons bound to a URL
MarkUpLabel	Adds text with GTK mark up (e.g. color and font manipulation)
Menu	A simple menu with a menu item label
MenuBar	A simple menu bar that contain one or more menus
MenuItem	A simple menu item that can have a sub menu
MenuToolButton	A menu tool button with a label or an icon
PlacesSidebar	Sidebar that displays frequently-used places in the file system
Scale	Allows for a number to be provided by the user
ScrolledWindow	Container for widgets needing scrolling, eg., multiline texts
RadioButton	A choice from multiple check buttons
Spinner	Showing that something is happening
TextView	Adds multiple lines of text
Toolbar	A tool bar that can contain one or more menu tool buttons
VBox, HBox	Widget containers which enable window layout design

Example

use GTK::Simple;
use GTK::Simple::App;

my $app = GTK::Simple::App.new( title => "Hello GTK!" );

$app.set-content(
    GTK::Simple::VBox.new(
        my $button = GTK::Simple::Button.new(label => "Hello World!"),
        my $second = GTK::Simple::Button.new(label => "Goodbye!")
    )
);

$app.border-width = 20;
$second.sensitive = False;
$button.clicked.tap({ .sensitive = False; $second.sensitive = True });
$second.clicked.tap({ $app.exit; });
$app.run;

The first three or four examples were written as mini tutorials to show how the system works. For more examples, please see the examples folder.

Limitations

The full functionality of GTK 3 is not available in this module.

Prerequisites

This module requires the GTK3 library to be installed. Please follow the instructions below based on your platform:

Debian Linux

sudo apt-get install libgtk-3-dev

Mac OS X

brew update
brew install gtk+3

Windows

Precompiled GTK3 DLLs are installed automatically with module installation.

Installation

To install it using zef (a module management tool bundled with Rakudo Star):

$ zef install GTK::Simple

Testing

• To run tests:

$ prove -e "perl6 -Ilib"

• To run all tests including author tests (Please make sure Test::Meta is installed):

$ zef install Test::META
$ AUTHOR_TESTING=1 prove -e "perl6 -Ilib"
