<para>
Input Methods provide a way for complex character sets to be used in GTK+.
Languages such as Chinese, Japanese, and Korean (often abbreviated to CJK)
use a large number of ideographs, making it impossible to support all
characters with a simple keyboard. Instead, text is usually
<emphasis>pre-edited</emphasis> using a phonetic alphabet and then
<emphasis>composed</emphasis> to form the ideographs.
</para>
<para>
GTK+ makes use of the input method mechanism provided by the X Windows
platform. When a GTK+ application is started, it opens a connection to the
input method appropriate for the current locale (if any). 
</para>
<para>
Widgets which handle textual input, such as #GtkEntry, need to do a number of
things to support internationalized text input:
<variablelist>
<varlistentry>
<term>When the widget is realized:</term>
<listitem><para>Check if an input method is being used with gdk_im_ready().
If it is, create a new <link linkend="gdk-Input-Contexts">Input Context</link>
using gdk_ic_new(). Find out which events the
<link linkend="gdk-Input-Contexts">Input Context</link> needs to receive
with gdk_ic_get_events(), and make sure that the widget's window receives
these events using gdk_window_set_events().
</para></listitem>
</varlistentry>

<varlistentry>
<term>When the widget's size, state or cursor position changes:</term>
<listitem><para>

using gdk_ic_set_attr().
</para></listitem>
</varlistentry>

<varlistentry>
<term>When the keyboard focus enters or leaves the widget:</term>
<listitem><para>
Call gdk_im_begin() or gdk_im_end() to start or finish editing the text.

<varlistentry>
<term>When the widget receives a key_press event:</term>
<listitem><para>

<!-- ##### STRUCT GdkIC ##### -->
<para>
The #GdkIC struct is an opaque structure representing an input context
for use with the global <link linkend="gdk-Input-Methods">Input Method</link>.
</para>


<!-- ##### STRUCT GdkICAttr ##### -->
<para>
The #GdkICAttr struct is used when getting and setting attributes of the
input context. It is used together with a #GdkICAttributesType mask which
specifies which of the fields are being set or returned.
</para>

@style: the pre-edit and status style. This attribute is required when
creating the #GdkIC, and cannot be changed.
@client_window: the #GdkWindow in which the input method will display its
pre-edit and status areas or create subwindows.
The preedit_area and status_area attributes are specified relative to this
window. This attribute is required when creating the #GdkIC, and cannot be
changed.
@focus_window: the #GdkWindow which is to be used when editing text.
gdk_im_begin() sets this attribute before starting the text input process,
so it is normally not necessary to set it elsewhere.
@filter_events: the mask of events that the input method requires.
See the gdk_ic_get_events() function. This attribute is read-only and is
never changed.
@spot_location: the position of the insertion cursor, for use with the
%GDK_IM_PREEDIT_POSITION style. The y coordinate specifies the baseline of
the text.
@line_spacing: the line spacing to be used in the pre-edit and status areas
when displaying multi-line text.
@cursor: the cursor to use in the input method's windows.
If this attribute isn't set it is determined by the input method.
@preedit_fontset: the font to use for the pre-edit area.
If this attribute isn't set it is determined by the input method.
@preedit_area: the area in which the input method will display pre-editing
data, used for the %GDK_IM_PREEDIT_POSITION and %GDK_IM_PREEDIT_AREA styles.
@preedit_area_needed: the area that the input method requests for displaying
pre-editing data, used for the %GDK_IM_PREEDIT_POSITION and
%GDK_IM_PREEDIT_AREA styles.
@preedit_foreground: the foreground color to use for the pre-edit area.
This color must already be allocated in the preedit_colormap.
If this attribute isn't set it is determined by the input method.
@preedit_background: the background color to use for the pre-edit area.
This color must already be allocated in the preedit_colormap.
If this attribute isn't set it is determined by the input method.
@preedit_pixmap: the background pixmap to use for the pre-edit area.
If this attribute isn't set it is determined by the input method.
@preedit_colormap: the colormap the input method should use to allocate colors.
The default value is the colormap of client_window.
@status_fontset: the font to use for the status area.
If this attribute isn't set it is determined by the input method.
@status_area: the are that the input method will display status information in.
This is used for the %GDK_IM_STATUS_AREA style.
@status_area_needed: the size that the input method requests for displaying
status information, for the %GDK_IM_STATUS_AREA style.
@status_foreground: the foreground color to use for the status area.
This color must already be allocated in the status_colormap.
If this attribute isn't set it is determined by the input method.
@status_background: the background color to use for the status area.
This color must already be allocated in the status_colormap.
If this attribute isn't set it is determined by the input method.
@status_pixmap: the background pixmap to use for the status area.
If this attribute isn't set it is determined by the input method.
@status_colormap: the colormap the input method should use to allocate colors.
The default value is the colormap of client_window.

<!-- ##### ENUM GdkICAttributesType ##### -->

<!-- ##### ENUM GdkIMStyle ##### -->
<para>
A set of bit-flags used to specify the input method styles which are supported
or which are currently in use. The flags can be divided into 2 groups, the
pre-edit flags and the status flags.
</para>
<para>
The pre-edit flags specify how pre-editing data is displayed.
For example, this could display the text being typed in the phonetic
alphabet before it is composed and inserted as an ideograph.
</para>
<para>
The status flags specify how status information is displayed.
The status information can be thought of as an extension of the
standard keyboard mode indicators, such as the Caps Lock indicator.
</para>
<note>
<para>
The %GDK_IM_PREEDIT_CALLBACKS and %GDK_IM_STATUS_CALLBACKS styles are not 
currently supported in GTK+.
</para>
</note>

@GDK_IM_PREEDIT_AREA: The application provides the input method with an area
in which to perform <emphasis>off-the-spot</emphasis> pre-editing.
@GDK_IM_PREEDIT_CALLBACKS: The application registers a number of callback
functions which are used to display pre-editing data.
@GDK_IM_PREEDIT_POSITION: The application provides the input method with the
position of the insertion cursor, for <emphasis>over-the-spot</emphasis>
pre-editing. The input method creates its own window over the widget to
display the pre-editing data.
@GDK_IM_PREEDIT_NOTHING: The input method uses the root X window to perform
pre-editing, so the application does not need to do anything.
@GDK_IM_PREEDIT_NONE: No pre-editing is done by the input method, or no
pre-editing data needs to be displayed.
@GDK_IM_PREEDIT_MASK: A bit-mask containing all the pre-edit flags.
@GDK_IM_STATUS_AREA: The application provides the input method with an area
in which to display status information.
@GDK_IM_STATUS_CALLBACKS: The applications registers a number of callback
functions which are used to display status information.
@GDK_IM_STATUS_NOTHING: The input method uses the root X window to display
status information, so the application does not need to do anything.
@GDK_IM_STATUS_NONE: The input method does not display status information.
@GDK_IM_STATUS_MASK: A bit-mask containing all the status flags.

If GTK+ has been compiled without support for input methods, or the current
locale doesn't need an input method, then this will return FALSE.
</para>

@Returns: TRUE if an input method is available and should be used.

<!-- ##### FUNCTION gdk_im_set_best_style ##### -->
<para>
Sets the best pre-edit and/or status style which should be used.

The order of the status styles is:
%GDK_IM_STATUS_NONE, %GDK_IM_STATUS_NOTHING, %GDK_IM_STATUS_AREA,
%GDK_IM_STATUS_CALLBACKS.
</para>
<para>
So, for example, to set the best allowed pre-edit style to %GDK_IM_PREEDIT_AREA
you would do this:

<informalexample>
<programlisting>
  gdk_im_set_best_style (GDK_IM_PREEDIT_AREA);
</programlisting>
</informalexample>

Or to set the best allowed pre-edit style to %GDK_IM_PREEDIT_POSITION and the
best allowed status style to %GDK_IM_STATUS_NOTHING you can do this:

<informalexample>
<programlisting>
  gdk_im_set_best_style (GDK_IM_PREEDIT_POSITION | GDK_IM_STATUS_NOTHING);
</programlisting>
</informalexample>
</para>

@best_allowed_style: a bit-mask with the best pre-edit style and/or the best
