Itworks on many UNIX-like platforms, Windows, and on framebufferdevices. GTK+ is released under the GNU Library General Public License(GNU LGPL), which allows for flexible licensing of clientapplications. GTK+ has a C-based object-oriented architecture thatallows for maximum flexibility. Bindings for other languages havebeen written, including C++, Objective-C, Guile/Scheme, Perl, Python,TOM, Ada95, Free Pascal, and Eiffel. </p><p>GTK+ depends on the following libraries:</p><div class="variablelist"><table border="0"><col align="left" valign="top"><tbody><tr><td><p><span class="term">GLib</span></p></td><td><p>A general-purpose utility library, not specific to graphical user interfaces.GLib provides many useful data types, macros, type conversions,string utilities, file utilities, a main loop abstraction, and so on.</p></td></tr><tr><td><p><span class="term">Pango</span></p></td><td><p>Pango is a library for internationalized text handling. It centersaround the #PangoLayout object, representing a paragraph of text. Pango provides the engine for #GtkTextView, #GtkLabel, #GtkEntry, andother widgets that display text.</p></td></tr><tr><td><p><span class="term">ATK</span></p></td><td><p>ATK is the Accessibility Toolkit. It provides a set of genericinterfaces allowing accessibility technologies to interact with agraphical user interface. For example, a screen reader uses ATK todiscover the text in an interface and read it to blind users. GTK+widgets have built-in support for accessibility using the ATKframework.</p></td></tr><tr><td><p><span class="term">GdkPixbuf</span></p></td><td><p>This is a small library which allows you to create #GdkPixbuf("pixel buffer") objects from image data or image files. Use a #GdkPixbuf in combination with #GtkImage to display images.</p></td></tr><tr><td><p><span class="term">GDK</span></p></td><td><p>GDK is the abstraction layer that allows GTK+ to support multiplewindowing systems. GDK provides drawing and window system facilitieson X11, Windows, and the Linux framebuffer device.</p></td></tr><tr><td><p><span class="term">GTK+</span></p></td><td><p>The GTK+ library itself contains <em class="firstterm">widgets</em>, that is, GUI components such as #GtkButton or #GtkTextView.</p></td></tr></tbody></table></div><p> </p><div class="toc"><p><b>Table of Contents</b></p><dl><dt><span class="refentrytitle"><a href="gtk-building.html">Compiling the GTK+ libraries</a></span><span class="refpurpose"> — How to compile GTK+ itself</span></dt><dt><span class="refentrytitle"><a href="gtk-compiling.html">Compiling GTK+ Applications</a></span><span class="refpurpose"> — How to compile your GTK+ application</span></dt><dt><span class="refentrytitle"><a href="gtk-running.html">Running GTK+ Applications</a></span><span class="refpurpose"> — How to run and debug your GTK+ application</span></dt><dt><span class="refentrytitle"><a href="gtk-x11.html">Using GTK+ on the X Window System</a></span><span class="refpurpose"> — X11 aspects of using GTK+</span></dt><dt><span class="refentrytitle"><a href="gtk-windows.html">Using GTK+ on Windows</a></span><span class="refpurpose"> — Windows-specific aspects of using GTK+</span></dt><dt><span class="refentrytitle"><a href="gtk-osx.html">Using GTK+ on Mac OS X</a></span><span class="refpurpose"> — OS X-specific aspects of using GTK+</span></dt><dt><span class="refentrytitle"><a href="gtk-directfb.html">Using GTK+ on DirectFB</a></span><span class="refpurpose"> — DirectFB-specific aspects of using GTK+</span></dt><dt><span class="refentrytitle"><a href="gtk-resources.html">Mailing lists and bug reports</a></span><span class="refpurpose"> — Getting help with GTK+</span></dt><dt><span class="refentrytitle"><a href="gtk-question-index.html">Common Questions</a></span><span class="refpurpose"> — Find answers to common questions in the GTK+ manual</span></dt></dl></div></div></div></body></html>⌨️ 快捷键说明
