Coursework 2: Responsive Layouts
Date set: 9.11.20
Date due: 23.11.20
Weighting: 35%
Goals for this CW:
● Demonstrate a working understanding of writing custom layouts
in C++ and Qt
● Create a prototype layout for an app
● Design a beautiful responsive layout
Getting started:
● Watch the video.
● Download and extract this zip file
● Open the .pro file with Qt Creator
● Set the first command line argument to point to the folder which
contains your unzipped source code. Add double quotes around
the folder.
● Run the project. It creates a main window with several coloured
labels which can be manually resized. Try changing the size of the
window; observe the responsive design - the number, location and
size of the widgets change.
● Run the project in automatic test mode (warning your screen
will flash rapidly):
1. Add a second command line argument: test (without
quotes).
2. Run the program again.
3. Observe that a number of different window sizes are
displayed, screenshots are taken, and written to the report
directory in the root of the project. The program then exits.
View the report/index.html in a browser and observe the
terrible responsive design.
4. Set the project back to manual mode for your
development by removing the program argument test.
● There is a new system for generating a file to submit. Try this
now.
1. add a second command line argument pack (without
quotes)
2. run the program again. Check the "Application Output"
tab in Qt Creator for any error messages.
3. your files and report are packed into a file submit.patch
in the directory above your source output.
4. check that your submit.patch contains both your
automatically generated report and your source code by
replacing the command line argument pack with unpack.
This will extract to the submit.patch to the directory

tmp_xxxx, located next to the patch file. (you should do this
before submission!)
5. Your project will be graded using this automatic script
and report; you are encouraged to submit early and
often….
6. ...so please submit this default submit.patch to Minerva
now.
● The project contains three important C++ classes:
1. ResponsiveWindow: This subclasses QWidget and
creates the widgets to be displayed in the
ResponsiveWindow::createWidgets function. It sets
a ResponsiveLayout and adds various
ResponsiveLabels.
2. ResponsiveLayout: This subclasses QLayout and
arranges the ResponsiveLabels in the window using the
ResponsiveLayout::setGeometry function.
3. ResponsiveLabel: This subclasses QLabel and
creates a label widget with a name and a coloured
background.
● Read the classes to understand how they work together to
create the layout you have observed. Lecture 6 discusses such
custom layouts.
● The following widgets and associated colours have been
predefined in the ResponsiveLabel header file. (Lecture 5
introduces some useful terminology):
1. home link (kHomeLink)
2. shopping basket button (kShoppingBasket)
3. sign-in - assume user is logged out (kSignIn)
4. navigation tags - main site areas (kNavTabs)
5. advertisements for related products (kAdvert)
6. search button (kSearchButton)
7. search result - there may be several of these on one
page (kSearchResult)
8. search text field (kSearchText)
9. show next page of search results (kSearchForward)
10. show previous page of search results
(kSearchBackward)
11. detailed search options - price, product rating, category
etc.. (kSearchOptions)
Your task:
● You will create a prototype layout for a page of a mobile app.
This prototype will demonstrate which widgets are shown on what
sized devices and how their layout adapts in a responsive manner.
● In this coursework you will build a single responsive page layout
for a shopping app. The page will show search results.
● Notes:
○ You should carefully plan which labels are shown at
different screen sizes. You may wish to sketch the widgets
on paper before you write code.
