NAME¶

XmTextReplaceWcs — A Text function that replaces part of a wide character string in a Text widget "XmTextReplaceWcs" "Text functions" "XmTextReplaceWcs"

SYNOPSIS¶

#include <Xm/Text.h>
void XmTextReplaceWcs(
Widget widget,
XmTextPosition from_pos,
XmTextPosition to_pos,
wchar_t *wcstring);

DESCRIPTION¶

XmTextReplaceWcs replaces part of the wide character string in the Text widget. The character positions begin at 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 from_pos parameter must be 1 and the to_pos parameter must be 3. To insert a string after the fourth character, both the from_pos and to_pos parameters 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. This routine calls the widget's XmNmotionVerifyCallback callback when from_pos is less than or equal to the cursor position.
