To access this dialog box: In the Create Suppressions dialog box, click the Edit... button.
Use this dialog box while defining a suppression rule to:
View stack/traceback frames.
Choose a different stack/traceback frame as the rule focus.
Choose multiple stack/traceback frames as the rule focus.
Suppression rules are more robust if you specify a stack/traceback with multiple frames instead of frames with line numbers. (Because line numbers can be altered by code insertions or deletions, suppressions may be rendered ineffective by even minor code maintenance. Stack-based suppressions require larger code changes to invalidate them, such as changes to function call sequences.)
