| This page
is not intended to be a tutorial but instead it
will only give some ideas about programming,
particularly object-oriented programming. |
| |
| As I notice
it... there are lots of object-oriented
programming applications in the market nowadays.
And this is because object-oriented programming
has become an advantage in the creation of large
systems for use by big businesses as well as the
small ones... maybe this is because the need for
program coding and debugging is minimized making
their work a lot faster and easier. |

| Object-Oriented
Programming? |
| In my own
idea, when we say object-oriented programming...
as the word implies... we are dealing with
objects here and each Object contains
behaviors and characteristics. In this way each
object in an application is a self-contained
module which could mean that they can be
totally independent from other objects in the
application. In some applications this behaviors
and characteristics are represented as properties, events, and functions. |

| Event-Driven
Programming? |
| I don't
know if this can be called a characteristic of an
Object-Oriented Programming... but when we say Event-Driven,
this implies to the way your program is
executed by the computer... I think the other
type is called Procedural...
when we say Event-Driven, codes
in the application will not always be executed
sequentially nor randomly... this is because this
time the user is the one in charge of what is to
happen in the program. You might ask me why?
well... my reason is that in Event-Driven
programming there is such a thing as an event and this events contain the codes that
the programmer wants to be executed... this codes
are executed when a certain event is triggered by a user
action such as the pressing of a button or by
just typing a key in the keyboard, if the user
does nothing then not a single code is executed
too... this is not the same when we talk about Procedural
type of programming, in this type of programming,
codes are executed in the same order as they are
arranged or typed by the programmer, loops are to
be utilized if the programmer wants the program
to wait for a user action. |

| Properties |
| Properties
define an object's appearance like for example is
the window's appearance and behavior (a window's
color can be red, and it can have a minimize box
too) |
| |
| Events |
| Events are
triggered by user actions. This is where the
codes are placed so that they will be executed
once the user does something. |
| |
| Functions |
| Functions
perform processing specific to an application. |
