Week plan #10

For the week 7. November - 11. November

Preparations for the week

In this week and the next we turn to the BK textbook in order to gain some experiences on making graphical user interfaces, GUI's.

As a minimal preparation to this week study Chapter 11 of the BK textbook to the following extent:

Chapter 11: 11.1 - 11.4.4; pages 337-345:
- Read section 11.1, page 337, to be introduced to the concept of a GUI
- Section 11.2, page 338, states the three important concepts of making GUI's: components are to be arranged on a screen governed by a stated layout, and event handling offers the mechanism for the program to respond to user actions
- Section 11.3, pages 338-339, introduces the two GUI libraries AWT and Swing
- Section 11.4 - 11.4.4, pages 339-345, introduces the components label, button, menus, and menu items together with the principles of event handling showing how the program can respond to user choices of menu items.
  It's important not only to read, but also to practise some of the exercises while reading:
  Do Exercises 11.1 (page 341) and 11.2 - 11.5

The lectures

We will cover selected parts of the BK textbook, primarily
- Chapter 11, sections 11.1 - 11.5, pages 337-364.

Probably we will also take a look at the software calculator presented in section 6.5, pages 186-188 - the project calculator-full-solution

Exercises at the PC's

It's difficult to state a selection of exercises from the textbook to carry out because you will probably think on the GUI to be made for the Mandatory Assignment.

But some experience is useful to get. Try from the BK textbook Exercises 11.22 - 11.33

After the lectures

The lectures has not covered all details of pages 337-364 of the BK textbook. Work through the missing parts and do the exercises missed at the exercise class, refer to the section above. Feel free to add exercises of your own choice. Maybe, perform some experiments with relevance to the Mandatory Assignment.

After having covered inner classes and anonymous inner classes it's time to revisit some sections of the PS textbook in order to gain more acquaintance with classes:

Section 9.1 Class declarations and Class Bodies
Section 9.2 Top-Level Classes, Nested Classes, Member Classes, and Local Classes
Section 9.11 Nested Classes, Member Classes, Local Classes, and Inner Classes
Section 9.12 Anonymous Classes
Section 10.3 Inner Objects
Section 11.7 Object Creation Expressions
