Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off tools to complete application suites. GTK+ has been designed from the ground up to support a range of languages, 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 development. 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. GTK+ is the only 100% free-of-cost open source industrial-strength GUI toolkit available today. Since its origins as the toolkit for the GNU Image Manipulation Program (GIMP), GTK+ has been used in a wide range of software. Notably, GTK+ is the foundation of the GNOME desktop; GTK+ 2.14 will be incorporated into version 2.24 of the GNOME desktop. What's new in GTK+ 2.16 ======================= GTK+ 2.16 adds new functionality while maintaining source and binary compatibility with GTK+ 2.14. Highlights of new features and improvements in GTK+ 2.16 are: Noteworthy new APIs - GtkOrientable is a new interface implemented by all widgets that have horizontal and vertical variants - GtkActivatable is a new interface that must be implemented by widgets that are used as action proxies Changes in GtkEntry - GtkEntry can show icons at either side of the entry, which can be made clickable, drag sources, etc. - GtkEntry can show progress information behind the text. - GTK+ picks the best available placeholder character for password entries unless one is explicitly set. - GTK+ displays a Caps Lock warning in password entries. - Input methods can now be selected per-widget with the "im-module" property. Changes in GtkScale - GtkScale can now display annotated marks for certain values. Changes in GtkStatusIcon - GTK+ uses an extension of the tray icon specification to negotiate RGBA support. This is also supported by the GNOME panel. - GtkStatusIcon now supports scroll events, middle clicks and rich tooltips if the platform allows it. Changes in file chooser - The file chooser can optionally show file sizes. - Volumes are mounted when necessary. - GTK+ remembers the file chooser's window size across invocations. - Non-local uris can be entered in the location entry. Changes in printing support - Page rendering can be deferred to a thread. Internationalization support - Keyboard shortcut handling has been changed, to help with a longstanding complaint about the way in which GTK+ handles multiple keyboard layouts. GTK+ now only uses keys from groups other than the current group if they are not present in the current group. GDK changes - GdkKeymap emits a state-changed signal when the Caps Lock state changes. - There is a predefined type for blank cursors, GDK_BLANK_CURSOR.
