Introduction Please read this whole assignment tutorial letter before starting to ensure that you know what is expected of you and you do not get surprised by some requirement later in the development process. Please note that you must not use Qt Designer, and you are expected to manually set up GUIs to ensure that you properly handle memory using Qt’s parent-child functionality. Three sets of files have been provided for you so that you do not have to do it all from scratch: • COS3711A3_QMainWindow_template – use this template to set up the main GUIs. • COS3711A3_ContainerWidget – this contains a widget providing the setup of the one interface. • COS3711A3_Icons – this contains icons that you can use in the application. Use these to set up a project (using cmake, not qmake) that uses a QMainWindow as the user interface so that you can implement the functionality provided by a QMainWindow (menus, toolbar, status bar) to meet the requirements of the scenario given below. Marks will also be awarded for following good programming practice, for example, • naming conventions, • code layout and line spacing, • using initialiser lists in constructors, • using forward class declarations in header files, • enabling and disabling buttons as appropriate, • GUI handling like setting focus, sequential tabbing, clearing input widgets (like text input fields being cleared and spin boxes being returned to some default value), and • providing appropriate user feedback (including tooltips and messages to the user). Your code should build and run without any warnings. Consider the following scenario and then design a solution to meet the requirements listed. 2. Scenario Transporting cargo around the world is essential in ensuring that customers have access to the goods they need and want. Containers All such items are packaged in some sort of container, each of which has a code, weight, and volume (which should be calculated and expressed as an integer). For the purposes of this scenario, there are two kinds of containers. • A box, where we want to know its dimensions: length, breadth, and height.
