00:00:00,000 --> 00:00:00,420

00:00:00,420 --> 00:00:02,830
>> DAVID MALAN: Let's write a program
with a graphical user interface,

3
00:00:02,830 --> 00:00:04,210
otherwise known as a GUI.

4
00:00:04,210 --> 00:00:07,450
And for this, we'll use Stanford's
portable library, which comes with

5
00:00:07,450 --> 00:00:08,970
some header files of its own.

6
00:00:08,970 --> 00:00:10,330
Let's dive in.

7
00:00:10,330 --> 00:00:15,180
>> First, I'm going to include
a file called gwindow.h.

8
00:00:15,180 --> 00:00:18,230
And notice, first that I'm using quotes
instead of angle brackets

9
00:00:18,230 --> 00:00:20,880
because this header file happens
to be in a sub directory

10
00:00:20,880 --> 00:00:22,510
of my current directory.

11
00:00:22,510 --> 00:00:26,760
Next, let's declare main as
usual, int, main, void.

12
00:00:26,760 --> 00:00:30,590
And now let's proceed to instantiate,
so to speak, that is create a

13
00:00:30,590 --> 00:00:31,720
graphical window.

14
00:00:31,720 --> 00:00:35,260
Otherwise known as a gwindow,
as follows--

15
00:00:35,260 --> 00:00:40,250
Gwindow window equals new gwindow.

16
00:00:40,250 --> 00:00:43,170
>> And now I need to specify the width
and the height of this window.

17
00:00:43,170 --> 00:00:45,610
I'm going to go with something somewhat
arbitrary, but somewhat

18
00:00:45,610 --> 00:00:48,340
small, so that it fits within
the appliances window.

19
00:00:48,340 --> 00:00:52,710
Specifically, 320 by 240 pixels.

20
00:00:52,710 --> 00:00:56,510
Recall then, that a pixel is one
of those dots on your screen.

21
00:00:56,510 --> 00:01:00,270
Next, let's go ahead and do not much
of anything at all and simply pause

22
00:01:00,270 --> 00:01:01,950
for 500 milliseconds.

23
00:01:01,950 --> 00:01:04,349
Calling a function called pause
that also is in the

24
00:01:04,349 --> 00:01:05,720
Stanford portable library.

25
00:01:05,720 --> 00:01:09,830
>> Finally, after those five seconds, let's
go ahead and close the gwindow,

26
00:01:09,830 --> 00:01:11,260
as follows.

27
00:01:11,260 --> 00:01:14,330
And then let's return zero signifying
that we're all done.

28
00:01:14,330 --> 00:01:15,930
>> So what is this program done?

29
00:01:15,930 --> 00:01:19,330
Well, in a moment we should see, when
we run in, that it opens a window

30
00:01:19,330 --> 00:01:22,680
that's 320 pixels wide
by 240 pixels wide.

31
00:01:22,680 --> 00:01:25,130
That window just lingers there
for five seconds and then

32
00:01:25,130 --> 00:01:27,440
it should go away.

33
00:01:27,440 --> 00:01:32,290
Make window, dot, slash, window.

34
00:01:32,290 --> 00:01:35,240
And there's our window, on the top
left hand corner of my screen.

35
00:01:35,240 --> 00:01:38,720
And in just a few seconds it's gone.

36
00:01:38,720 --> 00:01:39,970
