Application Development with Qt Creator - Second Edition

Creating forms in Qt Designer

Let's create a simple calculator application using Qt Designer and two forms: one form that takes the arguments for an arithmetic operation and a second dialog form to present the results.

The example is contrived, but will show you how to create multiple user interface forms in both environments and give you practice in working with signals and slots.
