1 00:00:01,550 --> 00:00:07,310 OK, this video I want to show you to open files with Quinter, so we're going to do something on an 2 00:00:07,310 --> 00:00:10,220 open dialogue box, open file dialogue box. 3 00:00:10,220 --> 00:00:12,710 So I've created a new file called Opened Up Pie. 4 00:00:12,710 --> 00:00:17,150 And you'll notice that the beginning here, I put the same image importing stuff that we've been doing 5 00:00:17,150 --> 00:00:19,670 in the past because we're going to open an image file. 6 00:00:19,880 --> 00:00:21,320 So we're going to need to deal with the images. 7 00:00:21,350 --> 00:00:30,290 So to create an open dialogue and open dialogue box or an open file dialog box, we first need to import 8 00:00:30,290 --> 00:00:32,120 another thing from Kent. 9 00:00:32,270 --> 00:00:39,280 So we go from T Hinter import file dialog. 10 00:00:39,920 --> 00:00:43,630 So this is a file dialog box, so we need to import that. 11 00:00:43,820 --> 00:00:47,480 So down here we can just call route dot file name. 12 00:00:49,180 --> 00:00:54,460 Because we want to grab the file name of some file to open, right, and to get this, we want to open 13 00:00:54,460 --> 00:00:58,420 a little file dialog box, you know, on Windows, when you open a file in a little box, pops up, 14 00:00:58,420 --> 00:01:02,500 it has a list, all your files and you select which one you want to open, click open. 15 00:01:02,740 --> 00:01:04,150 We need to create that thing. 16 00:01:04,160 --> 00:01:08,080 So that is a file dialog. 17 00:01:09,370 --> 00:01:17,500 And now we want to ask open file name, right, and this is a function now we've got to designate a 18 00:01:17,500 --> 00:01:18,270 whole bunch of stuff here. 19 00:01:18,280 --> 00:01:27,610 So the first thing we need to do is tell it what initial directory to look in so we can go initial these 20 00:01:27,790 --> 00:01:31,090 are equals and then just designate what? 21 00:01:31,100 --> 00:01:33,920 So if you just want the C drive, that would be a foregone. 22 00:01:33,970 --> 00:01:34,240 Right. 23 00:01:34,510 --> 00:01:36,990 If you want we're in argues directory. 24 00:01:37,210 --> 00:01:38,250 We could just do that. 25 00:01:38,290 --> 00:01:38,590 Right. 26 00:01:38,950 --> 00:01:42,460 So now we want to give the box that pops up a little title. 27 00:01:42,490 --> 00:01:42,850 Right. 28 00:01:43,030 --> 00:01:44,850 And this can really be anything. 29 00:01:44,860 --> 00:01:45,900 It doesn't really matter. 30 00:01:46,180 --> 00:01:52,660 I'm just going to say open an image file, I don't know, whatever. 31 00:01:53,860 --> 00:01:54,830 So that'll work there. 32 00:01:55,090 --> 00:02:01,450 Now we have to designate the types of files that will allow our program to open, or at least that will 33 00:02:01,450 --> 00:02:04,480 allow it to show on the screen in that little box that pops up. 34 00:02:04,480 --> 00:02:04,660 Right. 35 00:02:04,680 --> 00:02:09,490 So, for instance, in our thing right here, we have. 36 00:02:10,430 --> 00:02:13,730 This Panji file, we also have an icon file. 37 00:02:13,760 --> 00:02:15,530 We also have a bunch of pie files. 38 00:02:15,980 --> 00:02:23,210 So these are the different file types dot pie, dot, Icko, Dot, PMG, looks like a runaway ruby file 39 00:02:23,210 --> 00:02:23,420 in there. 40 00:02:23,430 --> 00:02:29,360 I'm not sure how that got there, but we need to tell our program what images or what file types we 41 00:02:29,360 --> 00:02:31,640 want to be allowed open. 42 00:02:31,640 --> 00:02:31,950 Right. 43 00:02:32,150 --> 00:02:33,740 So we want PMG files. 44 00:02:33,740 --> 00:02:36,400 I'll show you how to do just all files as well. 45 00:02:36,740 --> 00:02:39,410 So to do that, we call file types. 46 00:02:42,900 --> 00:02:48,330 And set that equal to this sort of tuple thing here and now. 47 00:02:49,330 --> 00:02:58,090 It's for each thing we want to open, we need another set of parentheses, right, so inside of here, 48 00:02:58,270 --> 00:02:59,640 we need to give it a little message. 49 00:02:59,650 --> 00:03:02,230 Let's call this PG philes. 50 00:03:05,180 --> 00:03:09,830 And this really doesn't matter what it is, it's just a little message that pops up and I'll show you 51 00:03:09,830 --> 00:03:11,390 in a second what I mean by that. 52 00:03:11,600 --> 00:03:16,880 And in the second thing here inside of this second tube wall here, we need to designate the type of 53 00:03:16,880 --> 00:03:17,270 file. 54 00:03:17,270 --> 00:03:24,860 So you start out usually always with Star and then Dot PMG because we want to open PMG files. 55 00:03:24,890 --> 00:03:31,100 Now the star means open anything that ends in PNG stars like a wild card. 56 00:03:31,100 --> 00:03:36,470 So any file we have, the ends in PNG will show up. 57 00:03:37,220 --> 00:03:38,240 OK, so that's that. 58 00:03:38,510 --> 00:03:43,730 If you want to do more than just one thing, if you want also JPEG files, you just put a comma and 59 00:03:43,730 --> 00:03:47,150 then put another tuple and then here give you a little message. 60 00:03:47,150 --> 00:03:52,910 You can say, you know, JPEG files or whatever, and then you would put Stadt jpeg instead. 61 00:03:52,910 --> 00:03:54,140 Let's go all files. 62 00:03:55,220 --> 00:04:06,430 And inside here, we want any file with any names, so star that ends and got any extension, so OK, 63 00:04:06,650 --> 00:04:12,230 I think that is that now I put a bunch of spaces here, you don't have to actually put any spaces. 64 00:04:12,230 --> 00:04:16,700 I just thought it would be easier to sort of read the different sections of this. 65 00:04:17,270 --> 00:04:22,430 So, OK, now we can just run this if we save this and run it. 66 00:04:24,080 --> 00:04:32,940 Come back here and run, opened up high, and you could see right away it just opened this thing and 67 00:04:32,940 --> 00:04:34,460 now I'm in my guv's directory. 68 00:04:34,470 --> 00:04:36,450 This is the open file dialogue box. 69 00:04:36,450 --> 00:04:37,860 Here's the title at the top. 70 00:04:37,860 --> 00:04:42,090 Open an image file and we can see Assman PMG down here. 71 00:04:42,090 --> 00:04:43,460 It says PMG Files. 72 00:04:43,470 --> 00:04:46,320 That's the little thing that we typed. 73 00:04:47,440 --> 00:04:55,840 And let's see right right here, this PNG file, we also typed all files, so if we come back here. 74 00:04:56,750 --> 00:05:00,600 And down we could see it also says all files, if I type Bob there. 75 00:05:00,620 --> 00:05:04,740 It would show up as Bob and then Starr PMG. 76 00:05:04,760 --> 00:05:08,690 Right, but we type PMG files and all of us, we click all files, boom. 77 00:05:08,690 --> 00:05:12,380 It changes to all of the files in our directory. 78 00:05:12,670 --> 00:05:15,020 There's our Aspen, there's our all of our programs. 79 00:05:15,020 --> 00:05:16,040 There's that icon. 80 00:05:16,370 --> 00:05:19,280 There's that runaway ruby file that I'm not sure why it's in there. 81 00:05:19,610 --> 00:05:21,230 And so very cool so that we can click on this. 82 00:05:21,230 --> 00:05:22,790 And when we do, nothing happens. 83 00:05:23,030 --> 00:05:27,770 And here's our original file thing, and this video is getting a little bit long. 84 00:05:27,770 --> 00:05:33,650 In the next video, I'll show you how to actually open an image once we've selected it from that box. 85 00:05:33,950 --> 00:05:39,020 And we'll clean this up and make this to where it doesn't just throw the box when the program runs, 86 00:05:39,230 --> 00:05:43,400 we'll click a button or something to do that and we'll look at that in the next video.
