NAME

XmTextReplace — A Text function that replaces part of a text string

CONTENTS

SYNOPSIS

#include <Xm/Text.h>
void XmTextReplace(
Widget widget,
XmTextPosition from_pos,
XmTextPosition to_pos,
char * value);

DESCRIPTION

XmTextReplace replaces part of the text string in the Text widget. The character positions begin at 0 (zero) and are numbered sequentially from the beginning of the text.

An example text replacement would be to replace the second and third characters in the text string. To accomplish this, the parameter from_pos must be 1 and to_pos must be 3. To insert a string after the fourth character, both parameters, from_pos and to_pos, must be 4.

This routine calls the widget’s XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCallbackWcs, or both. If both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first and the resulting data is passed to the XmNmodifyVerifyCallbackWcs callbacks. The XmNmotionVerifyCallback is generated if to_pos is less than or equal to the cursor position and the length of value is not the same as the length of the text being replaced, or if the cursor position is between from_pos and to_pos, and the distance from the cursor position to from_pos is greater than the length of value.
widget Specifies the Text widget ID
from_pos Specifies the start position of the text to be replaced
to_pos Specifies the end position of the text to be replaced
value Specifies the character string value to be added to the text widget
