The Spec Gtk bindings for Pharo

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!

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

brew install gtk+3

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

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.

The following code should open a small UI:

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

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