<para>GTK+ is a multi-platform toolkit for creating graphical user
|
|
|
|

interfaces, originally designed with
|
|
|
|
|
the general look and feel of Motif. In reality, it looks much
|

|

<para>GTK+ provides some unique features. (At least, I know of
|
|
|
|
|
no other widget library which provides them). For example, a
|
|
|
|
|
button does not contain a label, it contains a child widget,
|
|
|
|
|
which in most instances will be a label. However, the child
|
|
|
|
|
widget can also be a pixmap, image or any combination possible
|
|
|
|
|
the programmer desires. This flexibility is adhered to
|
|
|
|
|
throughout the library.</para>
|
|
|
|
|
<para>GTK+ was initially developed as a widget set for the GIMP (GNU Image
|
|
|
|
|
Manipulation Program). It has grown extensively since then, and is today
|
|
|
|
|
used by a large number of applications, and is the toolkit used by the
|
|
|
|
|
<ulink url="http://www.gnome.org/">GNOME</ulink> desktop project.</para>

|

<para>GTK+ is free software and part of the GNU Project. However, the
|
|
|
|
|
licensing terms for GTK+, the GNU LGPL, allow it to be used by all developers,
|
|
|
|
|
including those developing proprietary software, without any license fees
|
|
|
|
|
or royalties.</para>
|
|
|

<para>GTK+ has been designed from the ground up to support a range of

|
|

|
<ulink url="http://www.gtk.org/bindings.html">

language bindings</ulink>, not only C/C++. Using GTK+ from languages

|

such as Perl and Python (especially in combination with the Glade GUI

builder) provides an effective method of rapid application
