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).

how the device coordinates map to the screen.
|
|
@has_cursor: if %TRUE, a cursor will be displayed indicating

the application is responsible for drawing a cursor
|
|
itself.
|
|
@num_axes: the number of axes for this device.
|

@axes: a pointer to an array of GdkAxisUse values which
|
|
give the mapping of axes onto the possible valuators

</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.

<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>
|

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.

@GDK_IM_PREEDIT_AREA: The application provides the input method with an area

@GDK_IM_PREEDIT_CALLBACKS: The application registers a number of callback

@GDK_IM_PREEDIT_POSITION: The application provides the input method with the

|
|
</para>
|
|
|
|
@supported_style: styles which are supported by the widget.

|
|
<!-- ##### FUNCTION gdk_im_ready ##### -->
|
|
<para>
|
|
Checks if an input method is to be used for the current locale.

|
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.

<!-- ##### FUNCTION gdk_im_set_best_style ##### -->

Sets the best pre-edit and/or status style which should be used.
|
|
This will affect the style chosen in gdk_im_decide_style().
|
|
</para>
|
|
<para>
|
|
The order of the pre-edit styles is (from worst to best):
|
|
%GDK_IM_PREEDIT_NONE, %GDK_IM_PREEDIT_NOTHING, %GDK_IM_PREEDIT_AREA,
|
|
%GDK_IM_PREEDIT_POSITION, %GDK_IM_PREEDIT_CALLBACKS.
|
|
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
|
|
status style to use. If 0 is used, then the current bit-mask of all allowed
|
|
styles is returned.

@Returns: a bit-mask of all the styles allowed.
|
|
|
