In this text box, specify the class pattern. A class pattern may start or end with an asterisk (*),
which stands for any number (including zero) of any characters. The patterns are matched against fully qualified class names.
Yoy can type a pattern manually or click the Browse button to open the Choose Class dialog box, locate the classes to be defined through the pattern, and compose the pattern based on this prompt. You can search for classes both by their names or in the project tree view.
