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+ 2.18 will be incorporated into version 2.28 of the GNOME desktop. What's new in GTK+ 2.18 ======================= GTK+ 2.18 adds new functionality while maintaining source and binary compatibility with GTK+ 2.16. Highlights of new features and improvements in GTK+ 2.18 are: Noteworthy new APIs GtkInfoBar - A new widget to show a transient 'message area' inside a content pane. The API is similar to GtkDialog and supports theming for different message types (warnings, errors, etc) Changes in GtkBuilder - Scale marks can be specified in builder markup - GtkAssistant action widgets can be added in builder markup Changes in GtkLabel - GtkLabel can show embedded URLs, much like SexyUrlLabel Changes in GtkEntry - GtkEntry has been refactored to follow the model-view pattern, with GtkEntryBuffer as model. One intended use case for this is to support 'secure memory' for password entries Changes in the file chooser - Backup files are hidden by default - GTK+ remembers the sorting state of the file list - File sizes are shown by default - The 'Create Folder' button can be disabled with the the ::create-folders property Changes in printing support - GTK+ supports authentication against CUPS servers - A backend for the PAPI printing system has been added - The file and lpr backends can print multiple pages per sheet - The file backend can produce svg files - GTK+ supports printing an application-defined 'selection' in addition to the usual page ranges - The print dialog can optinally include the page setup controls, avoiding the need for a separate page setup dialog in many situations Changes in theming support - The bullet character used in invisible entries can be set by themes with the ::invisible-char style property - The file chooser can show different icons for xdg user dirs. The icon names are folder-documents, folder-download, folder-music, folder-pictures, folder-publicshare, folder-templates and folder-video - The GtkInfoBar uses symbolic colors for theming its background color depending on the message type. The color names are info_fg_color, info_bg_color, warning_fg_color", warning_bg_color, etc. GDK changes - GDK has been rewritten to use 'client-side windows'. This means that GDK maintains its own window hierarchy and only uses X windows where it is necessary or explicitly requested. Some of the benefits of this change are * Reduced flicker * The ability to do transformed and animated rendering of widgets * Easier embedding of GTK+ widgets, e.g. into Clutter scene graphs See gdk-demo for some simple examples of client-side windows in action. See http://library.gnome.org/devel/gtk/2.18/gtk-migrating-ClientSideWindows.html for information about possible problems when moving to client-side windows.
