<para>
GTK+ provides resource file mechanism for configuring
various aspects of the operation of a GTK+ program
at runtime.
</para>

<refsect2><title>Default files</title>
<para>
An application can cause GTK+ to parse a specific RC
file by calling gtk_rc_parse(). In addition to this,
certain files will be read at the end of gtk_init().
Unless modified, the files looked for will be 
<filename>&lt;SYSCONFDIR&gt;/gtk-2.0/gtkrc</filename> 
and <filename>.gtkrc-2.0</filename> in the users home directory.
(<filename>&lt;SYSCONFDIR&gt;</filename> defaults to 
<filename>/usr/local/etc</filename>. It can be changed with the
<option>--prefix</option> or <option>--sysconfdir</option> options when 
configuring GTK+.)
</para>
<para>
The set of these <firstterm>default</firstterm> files
can be retrieved with gtk_rc_get_default_files()
and modified with gtk_rc_add_default_file() and
gtk_rc_set_default_files().
Additionally, the <envar>GTK2_RC_FILES</envar> environment variable
can be set to a #G_SEARCHPATH_SEPARATOR_S-separated list of files
in order to overwrite the set of default files at runtime.
</para>
<para><anchor id="locale-specific-rc"/>
For each RC file, in addition to the file itself, GTK+ will look for 
a locale-specific file that will be parsed after the main file. 
For instance, if <envar>LANG</envar> is set to <literal>ja_JP.ujis</literal>,
when loading the default file <filename>~/.gtkrc</filename> then GTK+ looks 
for <filename>~/.gtkrc.ja_JP</filename> and <filename>~/.gtkrc.ja</filename>, 
and parses the first of those that exists.
</para>
</refsect2>

<refsect2><title>Pathnames and patterns</title>
<para>
A resource file defines a number of styles and key bindings and
attaches them to particular widgets. The attachment is done
by the <literal>widget</literal>, <literal>widget_class</literal>,
and <literal>class</literal> declarations. As an example
of such a statement:
<informalexample><programlisting>
widget "mywindow.*.GtkEntry" style "my-entry-class"
</programlisting></informalexample>
attaches the style <literal>"my-entry-class"</literal>
to all widgets whose <firstterm>widget class</firstterm>
matches the <firstterm>pattern</firstterm>
<literal>"mywindow.*.GtkEntry"</literal>.
</para>
<para>
The patterns here are given in the standard shell glob
syntax. The <literal>"?"</literal> wildcard matches
any character, while <literal>"*"</literal> matches
zero or more of any character. The three types of
matching are against the widget path, the
<firstterm>class path</firstterm> and the class
hierarchy. Both the widget and the class paths consists of a
<literal>"."</literal> separated list of all the
parents of the widget and the widget itself from
outermost to innermost. The difference is that in
the widget path, the name assigned by
gtk_widget_set_name() is used
if present, otherwise the class name of the widget, while
for the widget path, the class name is always used.
</para>
<para>
So, if you have a #GtkEntry named
<literal>"myentry"</literal>, inside of a of a window
named <literal>"mywindow"</literal>, then the
widget path is: <literal>"mwindow.GtkHBox.myentry"</literal>
while the class path is: <literal>"GtkWindow.GtkHBox.GtkEntry"</literal>.
</para>
<para>
Matching against class is a little different. The pattern
match is done against all class names in the widgets
class hierarchy (not the layout hierarchy) in sequence, so the
pattern:
<informalexample><programlisting>
class "GtkButton" style "my-style"
</programlisting></informalexample>
will match not just #GtkButton widgets,
but also #GtkToggleButton and
#GtkCheckButton widgets, since
those classes derive from #GtkButton.
</para>
</refsect2>

<refsect2><title>Toplevel declarations</title>
<para>
An RC file is a text file which is composed of a sequence
of declarations. <literal>'#'</literal> characters delimit comments and
the portion of a line after a <literal>'#'</literal> is ignored when parsing
an RC file.
</para>

<para>
The possible toplevel declarations are:

<variablelist>
  <varlistentry>
    <term><literal>binding <replaceable>name</replaceable>
     { ... }</literal></term>
    <listitem>
      <para>Declares a binding set.</para>

          [ style | binding [ : <replaceable>priority</replaceable> ]]
          <replaceable>name</replaceable></literal></term>
    <listitem>
     <para>Specifies a style or binding set for a particular

        it is searched in the directories of the currently open RC files.
      </para>
      <para>GTK+ also tries to load a 
        <link linkend="locale-specific-rc">locale-specific variant</link> of
        the included file.

</variablelist>
</para>
</refsect2>

<refsect2><title>Styles</title>
<para>
A RC style is specified by a <literal>style</literal> 
declaration in a RC file, and then bound to widgets
with a <literal>widget</literal>, <literal>widget_class</literal>,
or <literal>class</literal> declaration. All styles
applying to a particular widget are composited together
with <literal>widget</literal> declarations overriding
<literal>widget_class</literal> declarations which, in
turn, override <literal>class</literal> declarations.
Within each type of declaration, later declarations override
earlier ones.
</para>

<para>
Within a <literal>style</literal> declaration, the possible
elements are:

<variablelist>
  <varlistentry>

         in place of the <literal>base</literal> color. The special
         value <literal>"&lt;parent&gt;"</literal> may be used to indicate that the widget should
         use the same background pixmap as its parent. The special value

  </varlistentry>
</variablelist>
</para>
<para>
The colors and background pixmaps are specified as a function of the
state of the widget. The states are:

<variablelist>
  <varlistentry>
    <term><literal>NORMAL</literal></term>
    <listitem>
      <para>
        A color used for a widget in its normal state.

    </listitem>
  </varlistentry>
  <varlistentry>
    <term><literal>ACTIVE</literal></term>
    <listitem>
      <para>
        A variant of the <literal>NORMAL</literal> color used when the
        widget is in the %GTK_STATE_ACTIVE state, and also for
        the trough of a ScrollBar, tabs of a NoteBook
        other than the current tab and similar areas.
        Frequently, this should be a darker variant
        of the <literal>NORMAL</literal> color.
      </para>
    </listitem>
  </varlistentry>
  <varlistentry>
    <term><literal>PRELIGHT</literal></term>
    <listitem>
      <para>
        A color used for widgets in the %GTK_STATE_PRELIGHT state. This
        state is the used for Buttons and MenuItems
        that have the mouse cursor over them, and for 
        their children.
      </para>
    </listitem>
  </varlistentry>
  <varlistentry>
    <term><literal>SELECTED</literal></term>
    <listitem>
      <para>
        A color used to highlight data selected by the user.
        for instance, the selected items in a list widget, and the
        selection in an editable widget.
      </para>
    </listitem>
  </varlistentry>
  <varlistentry>
    <term><literal>INSENSITIVE</literal></term>
    <listitem>
      <para>
        A color used for the background of widgets that have
        been set insensitive with gtk_widget_set_sensitive().
      </para>
    </listitem>
  </varlistentry>
</variablelist>
</para>

<para><anchor id="color-format"/>
Colors can be specified as a string containing a color name (GTK+ knows
all names from the X color database 
<filename>/usr/lib/X11/rgb.txt</filename>),  
in one of the hexadecimal forms <literal>&num;rrrrggggbbbb</literal>,
<literal>&num;rrrgggbbb</literal>, <literal>&num;rrggbb</literal>,
or <literal>&num;rgb</literal>, where <literal>r</literal>,
<literal>g</literal> and <literal>b</literal> are
hex digits, or they can be specified as a triplet 
<literal>{ <replaceable>r</replaceable>, <replaceable>g</replaceable>,
<replaceable>b</replaceable>}</literal>, where <literal>r</literal>,
<literal>g</literal> and <literal>b</literal> are either integers in 
the range 0-65635 or floats in the range 0.0-1.0.
</para>

<para>
In a <literal>stock</literal> definition, icon sources are specified as a
4-tuple of image filename, text direction, widget state, and size, in that
order.  Each icon source specifies an image filename to use with a given
direction, state, and size. The <literal>*</literal> character can be used as a
wildcard, and if direction/state/size are omitted they default to
<literal>*</literal>. So for example, the following specifies different icons to
use for left-to-right and right-to-left languages:
<informalexample><programlisting>
stock["my-stock-item"] = 
{
  { "itemltr.png", LTR, *, * },
  { "itemrtl.png", RTL, *, * }
}
</programlisting></informalexample>
This could be abbreviated as follows:
<informalexample><programlisting>
stock["my-stock-item"] = 
{
  { "itemltr.png", LTR },
  { "itemrtl.png", RTL }
}
</programlisting></informalexample>
</para>

<para>
You can specify custom icons for specific sizes, as follows:
<informalexample><programlisting>
stock["my-stock-item"] = 
{
  { "itemmenusize.png", *, *, "gtk-menu" },
  { "itemtoolbarsize.png", *, *, "gtk-large-toolbar" }
  { "itemgeneric.png" } /* implicit *, *, * as a fallback */
}
</programlisting></informalexample>
The sizes that come with GTK+ itself are <literal>"gtk-menu"</literal>,
<literal>"gtk-small-toolbar"</literal>, <literal>"gtk-large-toolbar"</literal>,
<literal>"gtk-button"</literal>, <literal>"gtk-dialog"</literal>. Applications
can define other sizes.
</para>

<para>
It's also possible to use custom icons for a given state, for example:
<informalexample><programlisting>
stock["my-stock-item"] = 
{
  { "itemprelight.png", *, PRELIGHT },
  { "iteminsensitive.png", *, INSENSITIVE }, 
  { "itemgeneric.png" } /* implicit *, *, * as a fallback */
}
</programlisting></informalexample>
</para>

<para>
When selecting an icon source to use, GTK+ will consider text direction most
important, state second, and size third. It will select the best match based on
those criteria. If an attribute matches exactly (e.g. you specified
<literal>PRELIGHT</literal> or specified the size), GTK+ won't modify the image;
if the attribute matches with a wildcard, GTK+ will scale or modify the image to
match the state and size the user requested.
</para>

</refsect2>

<refsect2><title>Key bindings</title>
<para>
Key bindings allow the user to specify actions to be 
taken on particular key presses. The form of a binding
set declaration is:
</para>

<informalexample><programlisting>
binding <replaceable>name</replaceable> {
  bind <replaceable>key</replaceable> { 
    <replaceable>signalname</replaceable> (<replaceable>param</replaceable>, ...)
    ...
  }
  ...
}
</programlisting></informalexample>

<para>
<replaceable>key</replaceable> is a string consisting of a 
series of modifiers followed by the name of a key. The
modifiers can be:
<simplelist>
<member><literal>&lt;alt&gt;</literal></member>
<member><literal>&lt;control&gt;</literal></member>
<member><literal>&lt;mod1&gt;</literal></member>
<member><literal>&lt;mod2&gt;</literal></member>
<member><literal>&lt;mod3&gt;</literal></member>
<member><literal>&lt;mod4&gt;</literal></member>
<member><literal>&lt;mod5&gt;</literal></member>
<member><literal>&lt;release&gt;</literal></member>
<member><literal>&lt;shft&gt;</literal></member>
<member><literal>&lt;shift&gt;</literal></member>
</simplelist>
<literal>&lt;shft&gt;</literal> is an alias for 
<literal>&lt;shift&gt;</literal> and 
<literal>&lt;alt&gt;</literal> is an alias for
<literal>&lt;mod1&gt;</literal>.
</para>

<para>
The action that is bound to the key is a sequence
of signal names (strings) followed by parameters for 
each signal. The signals must be action signals.
(See g_signal_new()). Each parameter can be
a float, integer, string, or unquoted string
representing an enumeration value. The types of
the parameters specified must match the types of the 
parameters of the signal.
</para>

<para>
Binding sets are connected to widgets in the
same manner as styles, with one addition. 
A priority can be specified for each pattern,
and within each type of pattern, binding sets
override other binding sets first by priority,
and only then by order of specification. (Later
overrides earlier). The priorities that can
be specified are (highest to lowest):
<simplelist>
<member><literal>highest</literal></member>
<member><literal>rc</literal></member>
<member><literal>theme</literal></member>
<member><literal>application</literal></member>
<member><literal>gtk</literal></member>
<member><literal>lowest</literal></member>
</simplelist>
<literal>rc</literal> is the default for bindings
read from an RC file, <literal>theme</literal>
is the default for bindings read from theme RC files,
<literal>application</literal> 
should be used for bindings an application sets
up, and <literal>gtk</literal> is used for bindings
that GTK+ creates internally.
</para>
