NAME
XmTextInsert - A Text function that inserts a character string into a text string SYNOPSIS
#include <Xm/Text.h> void XmTextInsert(widget, position, value) Widget widget; XmTextPosition position; char * value; DESCRIPTION
XmTextInsert inserts a character string into the text string in the Text widget. The character positions begin at zero and are numbered sequentially from the beginning of the text. For example, to insert a string after the fourth character, the parameter position must be 4. This routine calls the widget's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCall- backWcs, 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. Specifies the Text widget ID. Specifies the position in the text string where the character string is to be inserted. Specifies the character string value to be added to the text widget. For a complete definition of Text and its associated resources, see XmText(3X). SEE ALSO
