Chapter 4: Replaying GUI Events

Files:

• qtestlib/tutorial4/testgui.cpp

In this final chapter, we will show how to simulate a GUI event, and how to store a series of GUI events as well as replay them on a widget.

The approach to storing a series of events and replay them, is quite similar to the approach explained in chapter 2; all you need is to add a data function to your test class:
