GailTextUtil

GailTextUtil — GailTextUtil is a utility class which can be used to implement some of the AtkText functions for accessible objects which implement AtkText.

Types and Values

Description

GailTextUtil is a utility class which can be used to implement the AtkText functions which get text for accessible objects which implement AtkText.

In GAIL it is used by the accsesible objects for GnomeCanvasText, GtkEntry, GtkLabel, GtkCellRendererText and GtkTextView.

Functions

gail_text_util_new ()

GailTextUtil *
gail_text_util_new (void);

This function creates a new GailTextUtil object.

Returns

the GailTextUtil object


gail_text_util_text_setup ()

void
gail_text_util_text_setup (GailTextUtil *textutil,
                           const gchar *text);

This function initializes the GailTextUtil with the specified character string,

Parameters

textutil

The GailTextUtil to be initialized.

 

text

A gchar* which points to the text to be stored in the GailTextUtil

 

gail_text_util_buffer_setup ()

void
gail_text_util_buffer_setup (GailTextUtil *textutil,
                             GtkTextBuffer *buffer);

This function initializes the GailTextUtil with the specified GtkTextBuffer

Parameters

textutil

A GailTextUtil to be initialized

 

buffer

The GtkTextBuffer which identifies the text to be stored in the GailUtil.

 

gail_text_util_get_text ()

gchar *
gail_text_util_get_text (GailTextUtil *textutil,
                         gpointer layout,
                         GailOffsetType function,
                         AtkTextBoundary boundary_type,
                         gint offset,
                         gint *start_offset,
                         gint *end_offset);

This function gets the requested substring from the text in the GtkTextUtil. The layout is used only for getting the text on a line. The value is NULL for a GtkTextView which is not wrapped, is a GtkTextView for a GtkTextView which is wrapped and is a PangoLayout otherwise.

Parameters

textutil

A GailTextUtil

 

layout

A gpointer which is a PangoLayout, a GtkTreeView of NULL

 

function

An enumeration specifying whether to return the text before, at, or after the offset.

 

boundary_type

The boundary type.

 

offset

The offset of the text in the GailTextUtil

 

start_offset

Address of location in which the start offset is returned

 

end_offset

Address of location in which the end offset is returned

 

Returns

the substring requested


gail_text_util_get_substring ()

gchar *
gail_text_util_get_substring (GailTextUtil *textutil,
                              gint start_pos,
                              gint end_pos);

Gets the substring indicated by start_pos and end_pos

Parameters

textutil

A GailTextUtil

 

start_pos

The start position of the substring

 

end_pos

The end position of the substring.

 

Returns

the substring indicated by start_pos and end_pos

Types and Values

struct GailTextUtil

struct GailTextUtil {
  GObject parent;

  GtkTextBuffer *buffer;
};

enum GailOffsetType

Specifies which of the functions atk_text_get_text_before_offset(), atk_text_get_text_at_offset(), atk_text_get_text_after_offset() the function gail_text_util_get_text() is being called for.

Members

GAIL_BEFORE_OFFSET

Text before offset is required.

 

GAIL_AT_OFFSET

Text at offset is required,

 

GAIL_AFTER_OFFSET

Text after offset is required.
