Re: Carousel - like control for Mac OS
Unfortunately, on Mac OS this control does not support click on items detection, which makes it useless on Macs. from README.md: On Mac OS there is no easy way to detect clicks on carousel items currently. You cannot just supply an NSButton as or inside your item view because the transforms applied to the item views mean that hit detection doesn't work properly. I'm investigating possible solutions to this (if you know a good way to fix this, please get in touch, or fork the project on github). 2011/12/20 Tom Hohensee tom...@me.com: Have a look at iCarousel.

Re: Carousel - like control for Mac OS
Coverflow seems to be even more difficult to implement than just a simple smoothly scrollable strip with clickable items. Coverflow can be implemented using this iCarousel, but, again, with non-clickable items. And then, I do not have much space on the window to put this coverflow (while a strip can be small and still look good), plus a strip can display more than 1 item at once, and the user can click on any of these items without too much of scrolling). 2011/12/21 Stephen J.

Re: Carousel - like control for Mac OS
I am not sure how to do this. Currently, I have an NSScrollView (whose document view has all the item views), with hidden scroll bars, and buttons next and previous. When next and prev are clicked, I -scrollToPoint NSScrollView's content view a bit to the right or to the left. It seems to be working as I need, except that it doesn't scroll smoothly (I guess I need to use somehow). I suppose I need to attach a core animation layer to NSScrollView?

Re: Carousel - like control for Mac OS
HI Nick,
In my app, I have two IKImageBrowserView subclasses (thumbnailsBrowser) that I
populate with the pictures I need. It supports scrolling out of the box with
the mouse or trackpad when needed. For one of my subclass, I resize the popover
because it can only have up to 5 pictures in it, so I in fact disable
scrolling. The other one however, can have up to 50 images, so to also allow
scrolling with clicking a button, I wired two NSButton to this method:
- (IBAction)coverBrowserGo:(id)sender
{
NSIndexSet *currentlyVisible = [thumbnailsBrowser visibleItemIndexes];
if(debugging)
NSLog(@current IndexSet: %@, currentlyVisible);
if ([sender tag] == 0) //Go Left
{
// Are we already showing the first item?
if ([currentlyVisible firstIndex]==0)
return;
[thumbnailsBrowser scrollIndexToVisible:[currentlyVisible firstIndex]
-1];
}
else //Go Right
{
if(debugging)
{
NSLog(@resultMatchArray: %lu, [resultMatchArray count]);
NSLog(@lastIndex: %lu, [currentlyVisible lastIndex]);
}
// Are we already showing the last item?
if ([currentlyVisible lastIndex]+1==[resultMatchArray count])
return;
[thumbnailsBrowser scrollIndexToVisible:[currentlyVisible lastIndex]
+1];
}
}
To support clicking on an image, I have two choices. In one case I add the
IKImageBrowserController delegate method, where I can then get the index of the
currently selected index for aBrowser:
- (void) imageBrowserSelectionDidChange:(IKImageBrowserView *)aBrowser;
In the other case, I subclass the mouseUp method in my IKImageBrowserView
subclass, then pass data back to the delegate:
- (void) mouseUp:(NSEvent*)inEvent
{
id delegate = self.delegate;
if (delegate)
{
NSPoint mouse = [self convertPoint:[inEvent locationInWindow]
fromView:nil];
NSInteger objectIndex = [self indexOfItemAtPoint: mouse];
if (objectIndex == NSNotFound)
[delegate toggleCoverFloatingWindow:nil];
else
[delegate displayCoverFloatingWindow: objectIndex];
}
[super mouseUp:inEvent];
}
Hope that helps,
Olivier./.
Molowa.

Re: Carousel - like control for Mac OS
Nick, I cannot elaborate much on this and give you code (not because it is somehow confidential, but just because it is a general idea I don’t have implemented, though I’m familiar with CAScrollLayers). The idea is thus: 1. Draw a normal NSView that you back with a CAScrollLayer. Give it the right size. 2. Generate a NSArray of CALayers, each one initialized with a single image. 3. Put as sublayers of your CAScrollLayer as many CALayers as you want images displayed, giving each CALayer origin the right position (ex: (0,0) - (0, 100) - (0, 200) if you display three images of 100x100 pixels each). Your CAScrollLayer should have its origin at (0, 0). 4. Use standard event handling methods to detect mouse click. 5. If you want to scroll, say leftwards, add a new sublayer with the proper image at (0, 300), then animate the origin of the CAScrollLayer from (0,0) to (0, 100). Once the animation is done, you can safely remove the (0, 0) sublayer. 6. Go back to 4. The NSArray is a sort of cache where the CALayer live. This is more efficient than generating a CALayer on the fly each time you scroll.

Re: Carousel - like control for Mac OS
Have a look at iCarousel. Has a port for iOS as well as Mac OS. This can be done with ImageKit in IB as well. Just disable the scroll view and setup forward and back buttons that call the image index (nextIndex, etc). See imageKit docs.
