Introduction to Designer

The Qt Designer is a WYSIWYG (what you see is what you get) interface for laying out the widgets for your applications.

It allows you to drag and drop widgets onto your custom class and lay them out with minimal effort and 0 code. Your template will then be saved out to an XML based file (a .ui file) format that you can read into your application.

In this tutorial, we'll re-do our last code using Qt's designer to create our actions and link everything together.

Introduction to Layouts

Layouts are a powerful feature of Qt's GUI system - what they allow you to do is completely avoid having to deal with resizing logic.

If you have ever had to write your own code to determine how to resize the contents of a desktop application - you will be thrilled to never have to deal with that ever again.

This tutorial will take you through the basics of working with laying widgets out in Qt.
