1
00:00:00,000 --> 00:00:00,310

2
00:00:00,310 --> 00:00:03,050
>> SPIKA 1: Hebu kuandika mpango huo
ina graphical user interface kwamba

3
00:00:03,050 --> 00:00:06,940
ni pamoja na slider kwamba mtumiaji unaweza hoja
kushoto na kulia ili kuchagua baadhi

4
00:00:06,940 --> 00:00:08,720
thamani kati ya integers mbili.

5
00:00:08,720 --> 00:00:11,220
>> Kwa kufanya hivyo, nimekuwa imeanza na
baadhi placeholder code.

6
00:00:11,220 --> 00:00:12,720
Na sasa hebu kujaza tupu.

7
00:00:12,720 --> 00:00:17,760
Hebu kwanza kutenga GSlider, wito
ni slider, na hawawajui ni

8
00:00:17,760 --> 00:00:20,690
thamani ya kurudi kwa getGSlider.

9
00:00:20,690 --> 00:00:24,160
Na sasa hebu bayana kwamba nataka
kupunguza amefungwa ya slider kuwa

10
00:00:24,160 --> 00:00:28,800
integer ya 0, huku amefungwa juu ya
slider kuwa integer ya 100, na

11
00:00:28,800 --> 00:00:31,860
default thamani ya awali kuwa 50.

12
00:00:31,860 --> 00:00:35,760
>> Next, hebu kwenda mbele na kujiunga
hatua amri na slider hii kwa

13
00:00:35,760 --> 00:00:40,220
wito setActionCommand, kupita katika
slider, na kupita katika holela

14
00:00:40,220 --> 00:00:44,500
lakini msururu wa kipekee kama quote unquote
"Slide." Kwa maneno mengine, "slide" ni

15
00:00:44,500 --> 00:00:48,150
kwenda kuwa kitambulisho kipekee
kuhusishwa na slider hii.

16
00:00:48,150 --> 00:00:51,500
Tu katika kesi user interface yangu alikuwa
sliders nyingi, mimi nilikuwa kutofautisha

17
00:00:51,500 --> 00:00:53,180
kati yao na mbinu hii.

18
00:00:53,180 --> 00:00:58,620
>> Next, hebu simu addToRegion, kupita katika
dirisha, kupita katika slider, kupita

19
00:00:58,620 --> 00:01:03,310
katika quote unquote "SOUTH," ili
kuongeza slider kwa kusini

20
00:01:03,310 --> 00:01:04,830
mkoa wa user interface yetu.

21
00:01:04,830 --> 00:01:08,310
Ambapo quote unquote "SOUTH" hutokea kwa
kuwa kitambulisho kipekee inavyoelezwa katika

22
00:01:08,310 --> 00:01:09,950
Stanford Portable maktaba.

23
00:01:09,950 --> 00:01:12,760
>> Lakini sasa, kwa uwazi, kwa upande wa kushoto
ya slider hebu ngumu

24
00:01:12,760 --> 00:01:13,980
kificho idadi 0.

25
00:01:13,980 --> 00:01:17,020
Na upande wa kulia wa slider hebu
code ngumu namba 100.

26
00:01:17,020 --> 00:01:20,590
Ili mtumiaji anajua kwa sliding
kitu kwa upande wa kushoto au kulia jinsi

27
00:01:20,590 --> 00:01:22,170
wao ni kubadilisha thamani yake.

28
00:01:22,170 --> 00:01:26,060
>> Kabla ya sisi kutenga kwamba slider, hebu
kurudi nyuma hapa na kutenga GLabel,

29
00:01:26,060 --> 00:01:27,210
kuiita kushoto.

30
00:01:27,210 --> 00:01:32,170
Na hawawajui thamani ya kurudi kwa
newGLabel, kupita katika quote unquote -

31
00:01:32,170 --> 00:01:33,500
kwa maneno mengine -

32
00:01:33,500 --> 00:01:39,250
ya "0." Hebu sasa kuwaita addToRegion,
kupita katika dirisha, kupita katika upande wa kushoto,

33
00:01:39,250 --> 00:01:43,560
kupita katika quote unquote "SOUTH." Hivyo
kwamba studio hii ni kuingizwa katika kwamba

34
00:01:43,560 --> 00:01:45,600
mkoa wa kusini kabla ya slider.

35
00:01:45,600 --> 00:01:49,950
>> Na sasa baada ya slider, hebu kwenda
mbele na kutangaza mwingine GLabel.

36
00:01:49,950 --> 00:01:54,550
Wito haki, kumshirikisha ni
kurudi thamani ya newGLabel.

37
00:01:54,550 --> 00:01:56,320
Quote unquote - string mwingine -

38
00:01:56,320 --> 00:02:02,290
"100." Na kisha kuwaita addToRegion,
kupita katika dirisha, kupita katika haki,

39
00:02:02,290 --> 00:02:04,640
kupita katika "SOUTH" pia.

40
00:02:04,640 --> 00:02:08,580
Kwa maneno mengine, tumekuwa tu alitangaza
studio, slider, na studio nyingine na

41
00:02:08,580 --> 00:02:12,200
kuingizwa yao katika mkoa wa kusini
ili, ili mtumiaji anajua

42
00:02:12,200 --> 00:02:15,510
wakati yeye au yeye hatua hiyo kwa haki
au wa kushoto takribani nini thamani

43
00:02:15,510 --> 00:02:16,380
wao utakuwa inakaribia.

44
00:02:16,380 --> 00:02:19,040
>> Hebu sasa kutumika usio kitanzi.

45
00:02:19,040 --> 00:02:21,755
Na ndani ya kitanzi hii,
lets kuangalia kwanza kwa

46
00:02:21,755 --> 00:02:24,710
GActionEvent, na kuiita tukio hilo.

47
00:02:24,710 --> 00:02:27,740
Kumshirikisha ni kurudi
thamani ya waitForEvent.

48
00:02:27,740 --> 00:02:32,430
Kupita katika ACTION ya tukio, mara kwa mara
alitangaza katika Stanford Portable

49
00:02:32,430 --> 00:02:36,460
Maktaba hiyo inaonyesha kuwa wewe kweli
wanataka kusubiri hatua.

50
00:02:36,460 --> 00:02:42,420
>> Hebu kuangalia ijayo kama getEventType,
kupita katika tukio hilo, ni sawa na

51
00:02:42,420 --> 00:02:46,330
WINDOW_CLOSED, mara kwa mara nyingine alitangaza
katika Stanford Portable

52
00:02:46,330 --> 00:02:49,970
Maktaba ambayo inaonyesha kwamba hatua
ni ya kufunga dirisha.

53
00:02:49,970 --> 00:02:53,640
Basi kwenda mbele na kuvunja nje
hii kitanzi vinginevyo kubwa.

54
00:02:53,640 --> 00:02:57,480
>> Mwingine, hebu angalia kama mtumiaji
ametelezea kwamba slider.

55
00:02:57,480 --> 00:03:04,930
Kama kamba kulinganisha ya getActionCommand,
kupita katika tukio hilo, comma, quote unquote

56
00:03:04,930 --> 00:03:07,520
"Slide" ni sawa na ni sawa na 0.

57
00:03:07,520 --> 00:03:10,840
Kwa maneno mengine, kama kitambulisho kipekee
kuhusishwa na slider

58
00:03:10,840 --> 00:03:15,070
ambayo imekuwa slid sawa na quote unquote
"Slide," kitambulisho kipekee

59
00:03:15,070 --> 00:03:18,300
kwamba sisi zinazotolewa mapema, kisha
Nataka kufanya yafuatayo.

60
00:03:18,300 --> 00:03:25,040
>> Printf "slider ilikuwa slid kwa% i backslash
n, "kuonyesha kwamba Ningependa

61
00:03:25,040 --> 00:03:28,200
kuziba katika muhimu
thamani ya slider.

62
00:03:28,200 --> 00:03:34,300
Hivyo comma getValue ya slider.

63
00:03:34,300 --> 00:03:39,210
>> Hebu sasa kuokoa, kukusanya, kukimbia hii
mpango, na slide kwamba slider.

64
00:03:39,210 --> 00:03:41,200
Kufanya slider.

65
00:03:41,200 --> 00:03:42,990
. / Slider.

66
00:03:42,990 --> 00:03:44,270
Kuna user interface yangu.

67
00:03:44,270 --> 00:03:48,130
Kuna slider yangu, upande wa kushoto wa ambayo
ni 0, na haki ya ambayo ni

68
00:03:48,130 --> 00:03:49,820
100, wawili kati yao maandiko.

69
00:03:49,820 --> 00:03:52,740
Na kama mimi slide slider wa kushoto
na haki, taarifa kwamba katika wangu

70
00:03:52,740 --> 00:03:56,160
console dirisha mimi utaona
integer thamani.

71
00:03:56,160 --> 00:03:59,840
>> Sasa, mimi si lazima kuona yote ya
idadi kati ya 0 na 100, kwa sababu

72
00:03:59,840 --> 00:04:02,190
kulingana na kasi ambayo
Mimi hoja slider, yangu

73
00:04:02,190 --> 00:04:03,540
mpango ili taarifa.

74
00:04:03,540 --> 00:04:07,040
Lakini kwa kweli, kama mimi hoja hiyo kwa mtu yeyote
eneo fulani, hiyo ni thamani

75
00:04:07,040 --> 00:04:08,290
kwamba magazeti.

76
00:04:08,290 --> 00:04:10,006
