GTK::Simple

GTK::Simple is a set of simple GTK 3 bindings using NativeCall. Only some GTK widgets are currently implemented. However, these are enough to create a reasonable interactive GUI for an idiomatic Raku program. The GTK Widgets in this distribution 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 four examples were written as mini tutorials to show how the system works: - Hello world - Toggles - A simple grid - Marked Scales

For more examples, please see the examples/ folder.
