[masteen]

Overview

This is a simple string input dialog box with character checking and setting of some dialog  box characteristics

Description

The vi allows the user to set some characteristics of a string input dialog box. The vi is called with front panel window title, dialog box header text, string input label (actually caption) and default string input value. The input string is checked according to a regular expression and invalid characters are replaced by a replacement character, both specified in the call to the vi. The vi can remove white spaces before and after the string. The vi can be used as a model for other dialog boxes.
