Implemented Interfaces

GtkText implements AtkImplementorIface, GtkBuildable and GtkEditable.

Includes

#include <gtk/gtk.h>

Description

GtkText is deprecated and unsupported. It is known to be buggy. To use it, you must define the symbol GTK_ENABLE_BROKEN prior to including the GTK+ header files. Use GtkTextView instead.

A GtkText widget allows one to display any given text and manipulate it by deleting from one point to another, selecting a region, and various other functions as outlined below. It is inherited from GtkEditable.

Functions

gtk_text_new ()

GtkWidget *
gtk_text_new (GtkAdjustment *hadj,
              GtkAdjustment *vadj);

gtk_text_new is deprecated and should not be used in newly-written code.

Creates a new GtkText widget, initialized with the given pointers to GtkAdjustments. These pointers can be used to track the viewing position of the GtkText widget. Passing NULL to either or both of them will make the GtkText create its own. You can set these later with the function gtk_text_set_adjustment().

Parameters

hadj

horizontal adjustment.

 

vadj

vertical adjustment.

 

Returns

the new GtkText widget.


gtk_text_set_editable ()

void
gtk_text_set_editable (GtkText *text,
                       gboolean editable);

gtk_text_set_editable is deprecated and should not be used in newly-written code.

Sets whether the GtkText widget can be edited by the user or not. This still allows you the programmer to make changes with the various GtkText functions.

Parameters

text

the GtkText widget

 

editable

TRUE makes it editable, FALSE makes it immutable by the user

 

gtk_text_set_word_wrap ()

void
gtk_text_set_word_wrap (GtkText *text,
                        gboolean word_wrap);

gtk_text_set_word_wrap is deprecated and should not be used in newly-written code.

Sets whether the GtkText widget wraps words down to the next line if it can't be completed on the current line.

Parameters

text

the GtkText widget

 

word_wrap

TRUE makes it word wrap, FALSE disables word wrapping

 

gtk_text_set_line_wrap ()

void
gtk_text_set_line_wrap (GtkText *text,
                        gboolean line_wrap);

gtk_text_set_line_wrap is deprecated and should not be used in newly-written code.

Controls how GtkText handles long lines of continuous text. If line wrap is on, the line is broken when it reaches the extent of the GtkText widget viewing area and the rest is displayed on the next line. If it is not set, the line continues regardless size of current viewing area. Similar to word wrap but it disregards word boundaries.

Parameters

text

the GtkText widget

 

line_wrap

TRUE turns line wrap on, FALSE turns it off

 

gtk_text_set_adjustments ()

void
gtk_text_set_adjustments (GtkText *text,
                          GtkAdjustment *hadj,
                          GtkAdjustment *vadj);

gtk_text_set_adjustments is deprecated and should not be used in newly-written code.

Allows you to set GtkAdjustment pointers which in turn allows you to keep track of the viewing position of the GtkText widget.

Parameters

text

the GtkText widget

 

hadj

the horizontal adjustment

 

vadj

the vertical adjustment

 

gtk_text_set_point ()

void
gtk_text_set_point (GtkText *text,
                    guint index);

gtk_text_set_point is deprecated and should not be used in newly-written code.

Sets the cursor at the given point. In this case a point constitutes the number of characters from the extreme upper left corner of the GtkText widget.

Parameters

text

the GtkText widget

 

index

the number of characters from the upper left corner

 

gtk_text_get_point ()

guint
gtk_text_get_point (GtkText *text);

gtk_text_get_point is deprecated and should not be used in newly-written code.

Gets the current position of the cursor as the number of characters from the upper left corner of the GtkText widget.

Parameters

text

the GtkText widget

 

Returns

the number of characters from the upper left corner


gtk_text_get_length ()

guint
gtk_text_get_length (GtkText *text);

gtk_text_get_length is deprecated and should not be used in newly-written code.

Returns the length of the all the text contained within the GtkText widget; disregards current point position.

Parameters

text

the GtkText widget

 

Returns

the length of the text


gtk_text_freeze ()

void
gtk_text_freeze (GtkText *text);

gtk_text_freeze is deprecated and should not be used in newly-written code.

Freezes the GtkText widget which disallows redrawing of the widget until it is thawed. This is useful if a large number of changes are going to made to the text within the widget, reducing the amount of flicker seen by the user.

Parameters

text

the GtkText widget

 

gtk_text_thaw ()

void
gtk_text_thaw (GtkText *text);

Parameters

text

the GtkText widget

 

gtk_text_insert ()

gtk_text_insert (GtkText *text,
                 GdkFont *font,
                 const GdkColor *fore,
                 const GdkColor *back,
                 const char *chars,
                 gint length);

gtk_text_insert is deprecated and should not be used in newly-written code.
