provides a mechanism for configuring GTK+ key bindings through RC files. This eases key binding adjustments for application developers as well as users and provides GTK+ users or administrators with high key binding configurability which requires no application or toolkit side changes.</p><div class="refsect2" lang="en"><a name="id3259510"></a><h3>Installing a key binding</h3><a name="gtk-bindings-install"></a><p>A resource file binding consists of a 'binding' definition and a match statement to apply the binding to specific widget types. Details on the matching mechanism are described under <a class="link" href="gtk-Resource-Files.html#gtkrc-pathnames-and-patterns">Pathnames and patterns</a>.Inside the binding definition, key combinations are bound to specific signal emissions on the target widget. Key combinations are strings consisting of an optional <ahref="/usr/share/gtk-doc/html/gdk/gdk-Windows.html#GdkModifierType"><span class="type">GdkModifierType</span></a> name and <ahref="/usr/share/gtk-doc/html/gdk/gdk-Keyboard-Handling.html">key names</a> such as those defined in <code class="filename"><gdk/gdkkeysyms.h></code> or returned from <ahref="/usr/share/gtk-doc/html/gdk/gdk-Keyboard-Handling.html#gdk-keyval-name"><code class="function">gdk_keyval_name()</code></a>, they have to be parsable by <a class="link" href="gtk-Keyboard-Accelerators.html#gtk-accelerator-parse"><code class="function">gtk_accelerator_parse()</code></a>.Specifications of signal emissions consist of a string identifying the signal name, and a list of signal specific arguments in parenthesis.</p><p>For example for binding Control and the left or right cursor keys of a <a class="link" href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a> widget to the <a class="link" href="GtkEntry.html#GtkEntry-move-cursor"><span class="type">"move-cursor"</span></a> signal, so movement occurs in 3 letter steps, the following binding can be used:</p><div class="informalexample"><pre class="programlisting">binding "MoveCursor3" { bind "<Control>Right" { "move-cursor" (visual-positions, 3, 0) } bind "<Control>Left" { "move-cursor" (visual-positions, -3, 0) }}class "GtkEntry" binding "MoveCursor3"</pre></div><p></p><a name="gtk-bindings-unbind"></a><p>GTK+ already defines a number of useful bindings for the widgets it provides.Because custom bindings set up in RC files take precedence over the default bindings shipped with GTK+, overriding existing bindings as demonstrated in <a class="link" href="gtk-Bindings.html#gtk-bindings-install">Installing a key binding</a>works as expected. The same mechanism can not be used to "unbind" existing bindings, however.</p><div class="informalexample"><pre class="programlisting">binding "MoveCursor3" { bind "<Control>Right" { } bind "<Control>Left" { }}class "GtkEntry" binding "MoveCursor3"</pre></div><p>The above example will not have the desired effect of causing "<Control>Right" and "<Control>Left" key presses to be ignored by GTK+. Instead, it just causes any existing bindings from the bindings set "MoveCursor3" to be deleted, so when "<Control>Right" or "<Control>Left" are pressed, no binding for these keys is found in binding set "MoveCursor3". GTK+ will thus continue to search for matchingkey bindings, and will eventually lookup and find the default GTK+ bindings for entries which implement word movement. To keep GTK+ from activating its default bindings, the "unbind" keyword can be used like this:</p><div class="informalexample"><pre class="programlisting">binding "MoveCursor3" { unbind "<Control>Right" unbind "<Control>Left"}class "GtkEntry" binding "MoveCursor3"</pre></div><p>Now, GTK+ will find a match when looking up "<Control>Right" and "<Control>Left" key presses before it resorts to its default bindings, and the match instructs it to abort ("unbind") the search, so the key presses are not consumed by this widget.
