I really want to make a simple file browser in Xcode kind of like Finder itself, but it just displays one folder as a grid view. Can anyone direct me to a guide?
I recommend looking at Apple's code sample for SourceView.
It's probably a good place to start and should give you enough of an idea of where to begin.

I'm trying to add this feature to my app: when pushing a certain button, open a quick look view of a certain file.
I saw this:
Use Quick Look inside a Swift cocoa application to preview audio files,
but the error written in the comments shows up and the app crashes after trying to go back and forth between files.
Apple's class reference of QLPreviewPanel is quite empty.
Which is a correct implementation? What is wrong in the answer in the question I linked?
Apple's class reference of QLPreviewPanel is quite empty.
They have a lot of bugs currently. You can "View page source" in your browser, or use Xcode built-in help, it's pretty good.
Which is a correct implementation?
It looks like someone has already done it with Swift. I'm not sure if that's the full implementation.
What is wrong in the answer in the question I linked?
QLError() [...] called while the panel has no controller is decrypted this way: some class in the responder chain (your NSView or NSWindow should be there already, unless you have a very complex structure) must respond to acceptsPreviewPanelControl: and two other QLPreviewPanelController methods.
I want to know how to create button with my Images(PNG).
I'm not gonna use the GUIButton because of creating the default button image.
I copied the images in my Unity Project and changed to sprite(2D and UI). Then, create the sprites simply by dragging. I also added the script which includes 'onTouchDown() and onMouseDown'. However, it didn't work so I tired again with layermask but it didn't work as well with no error code. Maybe the physic2D is the reason.
How can i make button with simple image. Could you guys help me to do so?
Please let me know does anyone have idea. Thank you.
Why don't you use a button from the new UI system?
Sorry guys. I didn't recognize that i typed 'OnMouseDown' to 'onMouseDown'. I didn't used capital letter. It's really annoying thing.
I find a interesting website:http://www.brightpointinc.com/interactive/political_influence/
I want to learn its visualization using d3.
But when I download it, using right click button-------- save as The download page seems does not work. It seems lack some data, so I get back to the website to download some data, but it lacks some of them, can anyone send me an work version? thanks
As Lars says, your best bet is to look at the source code. To do this, you can use something like Chrome Developer Tools or Firebug for Firefox. I use the latter, so I'll take that as an example.
First, I'd right-click on the visualization itself, and click on Inspect Element with Firebug. This will pull up the HTML, which is only semi-helpful, since it only shows the output rather than the JavaScript code which created it.
To get at the JavaScript, you can use Firebug's Script tab. Most websites have more than one script, so you can hunt through the scripts being used by browsing through the dropdown menu in the second toolbar. The _buildChords.js script looks the most promising; that has some recognizable d3 code in it. You could check out the others to see what else they're calling (since it looks like there might be others - data.js, events.js, and so on).
Happy learning.
I start with describing the problem itself. Rather than a problem I'm looking for a better solution. I have a asp.net page which has a bunch of images and a link underneath it, Each image is infact the latest rendering of the link underneath it.
I scheduled a bat script which runs every hour to fetch the images through IECapt a web page rendering capture utility. One thing am annoyed about this utility is it takes a lot of time for the 20 images I have and for few because of the flash content it misses to take the actual screenshot of the website.
Now I like to know can this rendering be done by traditional programming am not interested in using any utilities. I'm interested in trying this. The solution need not be necessarily a C# based am ready to try in any other language. Because it gives me a chance to learn.
Thank you.
You should probably look at moz-headless-screenshot
You should be able to embed the functionality you need.
http://blog.mozilla.com/ted/2010/07/29/moz-headless-screenshot/
he also provided a sample embedding client application called moz-headless-screenshot.
This is a simple command line tool that takes a URL, image size, and output filename
and generates a PNG screenshot of the webpage.
You should look into browser shots:
http://browsershots.org/
They do what you want to do for lots of different browsers. It is even open source.
There's no simple-simple solution for what you're asking to do. This is because rendering HTML, CSS, and Flash is actually a very sophisticated process.
If you're up for quite a bit of coding, you can use the Gecko engine (which powers firefox) or another open-source web-browser core (ie Dillo) to render the page onto a custom canvas. Then save that canvas to a file. Unless you implement support for browser plug-ins, you won't get Flash this way, though. You could try using Gnash or its like. Good luck with that.
I don't know of an open-source project that already does this. It would be neat, though :-). If you write something, please push it to the world; it would be really cool to have a "get a screencap of this URL" tool.
One way is to use IRobotSoft web scraper. You can design a robot to go to the URL every hour, and capture the whole web page as an image via a function CapturePage(imagefile).
I am not sure if it will be better than IECapt though.
We have used ACA WebThumb ActiveX Control (http://www.acasystems.com/en/web-thumb-activex/) quite successfully to capture parts or whole of a web page in the web server and then to write them to a file, just passing in the url. It performs fast enough for our need.
I am not familiar with IECapt, but this might be something you might want to have a look at.
Can anyone point me in the direction of such a script? It should also be able to work when called into another ajax window. This is the type of gallery i am going for:
http://dageniusmarketer.com/DigitalWonderland/pages/DemoGalleryExample.html
It should go on this page:
dageniusmarketer.com/DigitalWonderland/
Portfolio section.
This script should be real simple to use with minimal extra files to make it work. I also should be able to just drop images in a gallery folder and it populates the gallery automatically with thumbnails....I shouldnt have to write code for each image in my html. Should be all dynamic.
I also would like to know how I could go about a window effect where every time I open up a new section via my navigation, the window shrinks closed with the old content, then expands open with the new content. the window effect should be vertical (top to bottom shrink into center, expand from center top to bottom)
Please Let me know. Thanks
JQuery is one of my personal favorite javascript libraries (along with 99% of this site apparently!)
But it will have a learning curve, as your requirements seem pretty specific, and you will have to read some documentation to pull it off.
Try Spry from Adobe. They have a very similar demo. Also, the other common frameworks for this would be prototype/scriptaculous, dojo, mootools, jquery. In many cases they have extensions that would provide the exact thing you are looking for. For example, try
shadowbox extension which is framework agnostic. Best of luck!
Imago looks promising:

Just discovered the very awesome-looking jQuery Tools library today. Meets your "simple and minimal" requirements and could probably pull off what you've sketched, with just the "tooltips" and "scrollable" components.
I also should be able to just drop images in a gallery folder and it populates the gallery automatically with thumbnails
My instinct is that you'd be better off writing server-side code to handle this part of your requirement.
