nsscrollview

I have many layer-backed views contained in a NSScrollview and am predominantly concerned with scrolling performance . The documentView and higher are layer-backed hence their subviews are also layer-backed. The following are the three natural places that display/rendering code could go: override NSView.wantsUpdateLayer to return false (or don't do anything because this is the default) & do drawing in NSView's drawRect method override NSView.wantsUpdateLayer to return true & do drawing in NSView's updateLayer method do NO drawing in NSView at all & perform all drawing in CALayer's

The NSScrollView containing a NSStackView. The NSStackView's items will add in runtime.The new NSStackView's items are from bottom to top, but I want they are from top to bottom. The main.storyboard The ViewController import Cocoa class ViewController: NSViewController { var todoList:[Todo] = [] @IBOutlet weak var todosStackView: NSStackView! @IBOutlet weak var todosScrollView: NSScrollView! @IBAction func onEnter(sender: NSTextField) { let todo = Todo() todo.content = sender.stringValue self.todoList.append(todo) let todoItemView = TodoItem() todoItemView.setButtonType(.SwitchButton)

I am working on a Mac OS X app using SDK 10.7 as deployment target. A NSScrollView contains a horizontal list of image thumbnails. The thumbnail which is in the center of the ScrollView indicates the selected image which is shown below the ScrollView in full size. This works quite similar the the Finder Cover-Flow, beside that the images in my app do not flow but just scroll away. I would like to limit the scrolling to stop only when a thumbnail is exactly in the center. The NSView method adjustScroll: is no solution. This would disable "smooth" scrolling and let the ScrollView jump from one

I need to disable programmatically scrolling in NSSrollView with enabled responsive scrolling. I try override isCompatibleWithResponsiveScrolling , then is possible to override scrollWheel and have enabled responsive scrolling but scrollWheel works different in that implementation. Is called only once, on start of scroll but I want to break scroll that is in progress. It's possible to do this in different way that not need to override scrollWheel method? 来源： https://stackoverflow.com/questions/41853163/how-to-disable-scrolling-in-nsscrollview-with-enabled-responsive-scrolling

I am building an application that utilizes an MDM API to make bulk updates to attributes of devices. I am looking to have some sort of visible output/logging in the main view so that the user can see what lines of their CSV may have failed and what the HTTP Response Code was. I can append to an NSTextField or a label easy enough, but seeing as how there may be a large output with many lines, I'd like to have a scrollable text box to append the information to. All of the documentation that I've found for doing this seems to be Swift 2, and this is the one piece of the puzzle I'm missing.

How can i detect scroll of position when the scroll at bottom? [[_scrollView contentView] setPostsBoundsChangedNotifications:YES]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(boundsDidChangeNotification:) name:NSViewBoundsDidChangeNotification object:[_scrollView contentView]]; - (void) boundsDidChangeNotification: (NSNotification *) notification { NSPoint currentScrollPosition = [[_scrollView contentView] bounds].origin; } Update : My original answer was plain wrong. Thanks to JWWalker and Wil Shipley for making me aware of that via comments. Here's a hopefully
