I'm drawing a colored gradient inside a rectangular Bezier curve within a custom View's drawRect method using drawInBezierPath. When I convert the view to a PDF using drawInBezierPath, the gradient is replaced with gray. Is this a bug, or am I doing something wrong? Thanks!

Hi, I'm trying to drag an NSTextView from one NSView to another. I'm getting the right events, but the drag animation is not coming up. Subclassed TextView: class MyTextView:NSTextView, NSPasteboardItemDataProvider { func pasteboard(_ pasteboard: NSPasteboard?, item: NSPasteboardItem, provideDataForType type: NSPasteboard.PasteboardType) { NSLog ("Paste") } override func mouseDown(with theEvent: NSEvent) { let pasteboardItem = NSPasteboardItem() pasteboardItem.setDataProvider(self, forTypes: [.string]) let draggingItem = NSDraggingItem(pasteboardWriter: pasteboardItem) draggingItem.setDraggingFrame(self.bounds, contents:.Publisher) beginDraggingSession(with: [draggingItem], event: theEvent, source: self) } override func draggingUpdated(_ sender: NSDraggingInfo) -> NSDragOperation { return NSDragOperation.copy } } Subclassed NSView to receive the drop event: class DropView:NSView { func EnableDrop () { // Registering for drag drop types registerForDraggedTypes([NSPasteboard.PasteboardType.string, NSPasteboard.PasteboardType.URL, NSPasteboard.PasteboardType.multipleTextSelection, NSPasteboard.PasteboardType.color]) } func shouldAllowDrag(_ draggingInfo: NSDraggingInfo) -> Bool { return true } override func draggingEntered(_ sender: NSDraggingInfo) -> NSDragOperation { // To show a copy tooltip during drop return NSDragOperation.copy } override func prepareForDragOperation(_ sender: NSDraggingInfo) -> Bool { return true } override func performDragOperation(_ draggingInfo: NSDraggingInfo) -> Bool { let draggedview = draggingInfo.draggingSource as! NSView NSLog ("Drop received") return true } } When I create my view in the ViewController, I do "myviewobj.EnableDrop()" to receive drop events. However as stated above, I'm not able to see the drag animation happening, however, I do get events for it.

I have an Objective-C App that has worked perfectly until Monterey was released. The app is activated and displays a window when it’s hotkey is typed. The problem is that—starting in Monterey—if the cursor is in an html Password field of ANY website in ANY browser, the app’s window does not display. After many many hours of debugging, I have determined that the problem is that in this case, [NSApp activateIgnoringOtherApps:YES] never activates the app, and that [myWindow makeKeyAndOrderFront:nil] does nothing. In this case, if I display a window using [NSApp runModalForWindow:myWindow], the window does display, but is not key until it is clicked, at which point the app activates. Note that everything works properly with the cursor in any browser field other than a Password field, or in any other app. It also works with the cursor anywhere in MacOS versions 10.12 through 11. Is this is some kind of new security feature? Is this a bug or is there a workaround for this? I there a low-level non-Cocoa way to activate an app?

I have a macOS app made with the Electron framework. Ever since I updated to macOS Sonoma, I've been facing a random crash whenever I click on the app menu/apple menu. This is not reproducible but happens quite often. On checking the crash report, I can notice that nil is being provided as an input to __NSPlaceholderDictionary initWithObjects method, but this crash does not happen in macOS Ventura or older versions. Is this due to any new validation added to the above method in macOS Sonoma ?

I have a doc, xib based project. it has an NSCollectionView, which properly displays the data. including items and section headers. I have drag n drop enabled where I can drop into the collectionView, and I generate a new object. this is NOT a reordering issue (yet) when I drop into the collectionView, if the drop is on top of a HeaderView, the drop is canceled (before it gets to my delegate code.) But more importantly : the Header views are entirely ignored in every step of the drag and drop. the hinting, only ever shows up adjacent to a collectionViewItemView, Never below or above the section header. The drop ALWAYS has a section of zero in its index path. regardless of where the drop is. I tried to override this behavior in both the validate drop and accept drop methods. with a great deal of frustration and struggle I discovered that I cannot compare the placement of my header views, because the frames of those views are all at the base origin point. is this normal behavior? Has anyone else run into this? is there a fix?

My app (AppKit, not SwiftUI) displays a small utility window. I can place it over the menu bar, or in the area beside the notch on my MacBook Pro (when it is a secondary screen), but if the screen goes to sleep and I wake it, macOS has moved the window off the menu bar or down out of the notch area. Is there any way to indicate a window should never be moved by the OS?

I have had this issue for a long time. If I configure any auto layout constraints in TableViewCell, I get extremely weird layout behavior in IB designer; however, layout is completely good during runtime. For example, with a completely new project and a single NSTableView on the main view, I get: If I resize main view, the tableview won't get resized Every time I reopen the project, the tableview would shrink by height. It seems the shrinked height is doubled every time. For example, in the following screenshot, the gap is 56. Next reopen will double the gap to 112. Is this a known bug? I would want to file bug report at https://feedbackassistant.apple.com.

Hello, Is it possible fill NSpastebard with public.file-url which will initially point the an empty file. And when Finder will paste the file, my Application will download it and Finder will wait for the completion of the download. My goal is not to use drag & drop. I saw that Microsoft RDP client is doing file download using this way. But I don't know how it works. Empty file is created in sandbox.

I have a Mac doc based app. I have save methods setup (they sort of work... I'm trying to get them up and running) I'm using NSSecureCoding, with NSObjects in Swift. It has been unusually frustrating. I have run into something I find wildly difficult to even explain. I can save a new document that has not been saved yet. it loads as expected. but if I make a change to a doc I have already saved, and save that, ny file gets wiped out. my save code is called, and the app wipes all of the data out of the saved file. The file exists, but it's emptied. it goes from around ~200k in size to 2k in size. there's no error that I have identified. It just wipes my file. So I have NO idea if it's something I did. docs are... unhelpful. internet searches... are unhelpful. this is just one of a number of errors I have to figure out, but it is massively complicating everything else. any ideas welcome.

I have an interesting challenge, but I do not know where to start. given an NSTextView in an NSScrollView, and enough text in the textView to enable scrolling, how do you determine the location of a single word, and jump to it? we see this sort of behavior in Find panels in Most text editors. So it can be done. additionally, I would very much like to find some kind of predetermined... elements in the text. as a link or an image is not text but can be inline with the text (in Attributed strings) I would like to put an element in the text that is not text, but is targetable and capable of being tagged with some kind of reference. Almost like a bookmark, in which I can scroll to. I have determined that I could use URL Links. But they are so fragile.

With my continued experiments with TextKit2, I'm trying to figure out what sets the properties paragraphSeparatorRange and paragraphContentRange on a NSTextParagraph. These seem to be computed properties (or at least they cannot be directly set via public API). var paragraph = NSTextParagraph(attributedString: NSAttributedString(string: "It was the best of times.\n")) print("attributes: \(paragraph.attributedString.attributes(at: 0, effectiveRange: nil))") print("paragraphSeparatorRange: \(String(describing: paragraph.paragraphSeparatorRange))") print("paragraphContentRange: \(String(describing: paragraph.paragraphContentRange))") In the above example, both paragraphSeparatorRange and paragraphContentRange are nil. However, when using NSTextLayoutManager/NSTextContentStorage they are set. let layoutManager = NSTextLayoutManager() let container = NSTextContainer(size: NSSize(width: 400, height: 400)) layoutManager.textContainer = container let contentStorage = NSTextContentStorage() contentStorage.textStorage = NSTextStorage(string: "It was the best of times.\n") contentStorage.addTextLayoutManager(layoutManager) layoutManager.enumerateTextLayoutFragments(from: contentStorage.documentRange.location, options: .ensuresLayout) { textLayoutFragment in print("layoutFragment: \(textLayoutFragment)") print("textElement: \(String(describing: textLayoutFragment.textElement))") print("textElement.range: \(String(describing: textLayoutFragment.textElement?.elementRange))") let paragraph = textLayoutFragment.textElement as! NSTextParagraph print("paragraphContentRange: \(String(describing: paragraph.paragraphContentRange))") print("paragraphSeparatorRange: \(String(describing: paragraph.paragraphSeparatorRange))") return true } Would appreciate any ideas on how these values are computed/set. Thanks

Hello, I need to change the text of an NSScrollView at run time, but the command below is not working: ScrViwRegras.documentView?.insertText (rules.retornaTextoRegras()) Where Rules is a struct that has the returnTextoRegras() method that returns the new text. Has anyone had this problem? Xcode 15.0.1 in MacBook Air not iOS), Swift 5, Hugs

If I use -[NSView dataWithPDFInsideRect:] to create a PDF from an NSTextView, I get a single-page PDF with stuff past the bottom cut off. What do I need to do to get pagination to happen? Would embedding the NSTextView in an NSScrollView help?

This message is logged in Xcode when I start editing a text field in my macOS app. This started appearing in Sonoma. This doesn't happen in Ventura (same Xcode project). Every text field in the app is affected, regardless of the window. What could be the cause of this?

The code below does not work properly in macos sonoma. I tested it on multiple Macs (mini, m1, intel), but it does not work the same way. (Normal operation in sonoma preview version and previous versions) NSOpenPanel* openPanel = [NSOpenPanel openPanel] Symptoms: When you press the button, the cursor changes to a whirlwind icon. My application and another system service (openAndSavePanelService) become "Not Responding". However, after a few minutes, this condition is resolved and my application returns to normal, but openAndSavePanelService continues to be in the "Not Responding" state. Suppose: Looking at the attached spindump, it is assumed that when openPanel init is called, a problem occurs in the process of communicating with xpc and the system service (openAndSavePanelService) for displaying the dialog box. What I tried: Without creating an instance when pressing the button NSOpenPanel* g_openPanel = [NSOpenPanel openPanel] When the task is attempted in main and the button is pressed, openPanel was attempted with the created instnace, but failed. Tried to work with NSOpenPanel* g_openPanel = [NSOpenPanel openPanel] via dispatch_async(dispatch_get_main_queue(), { ... }) but failed. I found similar questions on forums but they didn't help. https://developer.apple.com/forums/thread/104442?answerId=332068022#332068022 Project environment: Cocoa project Application is agent(UIElement) Hardened Runtime (apple event checked) No Sandbox Network Extension System Extension Deployment Target: 10.9 Could it be a permission issue? Is there anything else worth trying?

I wanted to add some dock menu options for my application when it is not running. These dock menu options can be used to launch the application. I came across dock TilePlugin that can be used to add these dock options. But one of the comments in this forum discussion mentions that these Plugins are not allowed if you want ot publish your application in the appStore. Can someone confirm this? If this is true, then Is there some other solution that can be used to add the dock options which appear when the application is not running, and can be used to launch the application? Also do the recent open Files appear using this plugin mechanism?

I have received a few crash reports for my app "Find Any File" with an assertion failure as follows: assertion failure: "displayTiming != ((void *)0)" -> %lld Googling this turns up nothing, though. I wonder if someone has some insight into why this might happen, and how to prevent it. One reporting user suggests that it happens when my app shows a very long list of items in an NSTableView (>10000 elements). I have 4 reports from 3 users, and the main thread is doing something related to the table view each time, though not the same (the few other threads are all idle): Crash 1, in macOS 14.0 (23A344: Thread 0:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x182c69400 objc_msgSend + 0 1 AppKit 0x186f15400 -[CALayer(NSViewVisibleRect) NS_viewVisibleRectDidChange] + 40 2 AppKit 0x186900e10 NSViewHierarchyInvalidateVisibleRect + 276 3 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 4 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 5 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 6 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 7 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 8 AppKit 0x1869990e0 -[NSView translateOriginToPoint:] + 164 9 AppKit 0x186984108 -[NSClipView _immediateScrollToPoint:] + 420 10 AppKit 0x186983eb8 -[NSClipView scrollToPoint:] + 184 11 AppKit 0x186998d80 -[NSScrollView scrollClipView:toPoint:] + 84 12 AppKit 0x1869448dc -[NSClipView _scrollTo:animateScroll:flashScrollerKnobs:] + 480 13 AppKit 0x186b65b24 __62-[NSScrollingBehaviorConcurrentVBL _stopGestureScrollTracking]_block_invoke + 192 14 AppKit 0x186e6a6e8 ___NSMainRunLoopPerformBlockInModes_block_invoke + 44 15 CoreFoundation 0x18310b8c0 __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ + 28 Crash 2, in macOS 14.1.1 (23B81): Thread 0:: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x18ba401f4 DYLD-STUB$$_Block_object_assign + 0 1 libsystem_blocks.dylib 0x18b506118 _call_copy_helpers_excp + 80 2 libsystem_blocks.dylib 0x18b505c68 _Block_copy + 376 3 libdispatch.dylib 0x18b641c7c _dispatch_Block_copy + 32 4 libdispatch.dylib 0x18b658df0 _dispatch_source_set_handler + 92 5 CoreFoundation 0x18b99e1e4 __CFRunLoopCopyMode + 540 6 CoreFoundation 0x18b8b7458 CFRunLoopAddObserver + 220 7 AppKit 0x18f0a687c _PerfAddRunLoopObserver + 192 8 AppKit 0x18f87cd60 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 368 9 AppKit 0x18f323318 -[_NSScrollingConcurrentEventMonitor startMonitoring] + 380 10 AppKit 0x18f321df8 -[NSScrollingBehaviorConcurrentVBL _scrollView:trackGestureScrollWithEvent:] + 884 11 AppKit 0x18f2e67f8 -[NSScrollingBehaviorConcurrentVBL scrollView:scrollWheelWithEvent:] + 512 12 AppKit 0x18f241770 forwardMethod + 252 13 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 14 AppKit 0x18f241770 forwardMethod + 252 15 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 16 AppKit 0x18f241770 forwardMethod + 252 17 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 18 AppKit 0x18f241770 forwardMethod + 252 19 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 20 AppKit 0x18fc45880 -[NSCollectionView scrollWheel:] + 180 21 AppKit 0x18f241770 forwardMethod + 252 22 AppKit 0x18f241770 forwardMethod + 252 23 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 24 AppKit 0x18f241770 forwardMethod + 252 25 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 26 AppKit 0x18f241770 forwardMethod + 252 27 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 28 AppKit 0x18f1d27b0 -[NSWindow(NSEventRouting) _reallySendEvent:isDelayedEvent:] + 652 As you can see, there's no code of mine involved at the time of crash. The other (and older) reports are similar, in macOS 13.6.1 and macOS 13.1. All four happened on ARM architecture (which may not be significant due to small number of samples). Memory use of app was not critical (in one case it was about 9 GB total, in others below 4 GB). The "Binary Images" section only lists Apple libs, apart from my app's. So, there seems to be no 3rd party ext involved. I've attached a full report as well. Full report of Crash 1
