# Pure GTK+ Bindings

Version 0.13, April 11, 2018

Albert Graef <aggraef@gmail.com>

pure-gtk is a collection of bindings to use the GTK+ GUI toolkit version 2.x with Pure, see http://www.gtk.org. The bindings include the gtk (+gdk), glib, atk, cairo and pango libraries, each in their own Pure module.

At present these are just straight 1-1 wrappers of the C libraries, created with pure-gen. So they still lack some convenience, but they are perfectly usable already, and a higher-level API for accessing all the functionality will hopefully become available in time. In fact you can help make that happen. :) So please let me know if you’d like to give a helping hand in improving pure-gtk.

## Installation

You can get the latest source from https://bitbucket.org/purelang/pure-lang/downloads/pure-gtk-0.13.tar.gz.

For Windows users, a ready-made package in msi format is available from https://bitbucket.org/purelang/pure-lang/downloads/pure-gtk-0.13.msi.

To install from source, do the usual `make && sudo make install` (see the Makefile for further options). This needs Pure and the GTK header files and libraries. You’ll also need pure-ffi for running the examples.

NOTE: The source release was prepared with GTK+ 2.24.4 on Ubuntu 11.04. If you’re seeing a lot of warnings and/or errors when compiling or loading the modules, your GTK headers are probably much different from these. In that case you should run `make generate` to regenerate the bindings; for this you also need to have pure-gen installed. (If you already have pure-gen then it’s a good idea to do this anyway.)

## Usage

See examples/hello.pure for a basic example. The files uiexample.pure and uiexample.glade show how to run a GUI created with the Glade-3 interface builder. This needs a recent version of the GtkBuilder API to work. (If you’re still running Glade-2 and an older GTK+ version, you might want to use the older libglade interface instead. Support for that is in the Makefile, but it’s not enabled by default.) NOTE: The examples start up much faster when they are compiled to native executables. To do this, just run `make examples` after `make`. (Be patient, this takes a while.)

pure-gtk can be discussed on the Pure mailing list at: http://groups.google.com/group/pure-lang
