Spec-Gtk

The Spec Gtk bindings for Pharo

How to install

On Windows

You need Gtk3!
And you need to put it at the same place of the Pharo.exe executable.
To simplify the process we created a VM bundled with all the DLL and resources needed to execute GTK+3

You can get it from: http://files.pharo.org/vm/pharo-spur64-headless/win/latest-win64-GTK.zip

NOTE: If you are running under cygwin subsystem, remember to chmod +x *. Libraries have to be executable!

On macOS:

You need Gtk3 (installed by brew because paths are fixed for now)

brew install gtk+3

On Linux

You need to have Gtk3 installed (this should be already the case).

Installing in your image

1. Download a Pharo 10.0 image:

curl get.pharo.org/100 | bash

2. Open your image using ./pharo-ui Pharo.image and evaluate:

 Metacello new
        repository: 'github://pharo-spec/Spec-Gtk';
        baseline: 'SpecGtk';
        onConflict: [ :e | e useIncoming ];
        onUpgrade: [ :e | e useIncoming ];
        ignoreImage;
        load

After the execution, save the image, and quit.

In macOS, if you open the image using ./pharo-ui Pharo.image, the image should give the feeling of being significantly slower. This is because the Gtk event loop is running. You can verify this by opening the process browser: you should see a line begining with (70) GtkRunLoop.

A first example

The following code should open a small UI:

SpLabelPresenter new
	application: (SpApplication new useBackend: #Gtk);	
	label: 'Hello, Gtk3';
	open.

Current status

Currently, only the low-level infrastructure is supported. Tools building based on solely Spec2/Gtk are under way. Be patient.
