NAME [Toc] [Back]
XmTextReplace - A Text function that replaces part of a text string
SYNOPSIS [Toc] [Back]
#include <Xm/Text.h>
void XmTextReplace(
Widget widget,
XmTextPosition from_pos,
XmTextPosition to_pos,
char * value);
DESCRIPTION [Toc] [Back]
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
