guitest_playback.C File Reference

Detailed Description

This macro plays a recorded ROOT session showing how to perform various interactive GUI operations with the guitest.C macro While replaying the session, several temporary macros (guitest0xx.C) macros will be saved.

These files will be later on compared with some reference values to verify the validity of different parts of the test.
