`XmTextFieldReplace`

A TextField function that replaces part of a text string

    #include <Xm/TextF.h>

    void XmTextFieldReplace

    Widget widget
    XmTextPosition from_pos
    XmTextPosition to_pos
    char * value

## DESCRIPTION

`XmTextFieldReplace` replaces part of the text string in the TextField 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.
