I have created a NSView inside the NSWindow. I m trying to identify when the view gets clicked by the user. For this I m using NSClickGestureRecognizer, but the registered method is not getting invoked. I have tried adding this for other widgets like button but it does not work either. Am I missing something? class SelectionList :NSObject, NSTextFieldDelegate{ let containerView = NSView() func createSelectionList (pWindow: NSWindow) { // created container View ... let clickRecognizer = NSClickGestureRecognizer() clickRecognizer.target = self clickRecognizer.buttonMask = 0x2 // right button clickRecognizer.numberOfClicksRequired = 1 clickRecognizer.action = #selector(ClickGestured) containerView .addGestureRecognizer(clickRecognizer) } @objc func clickRecognizer() { print("clicked") } }

I have an application with storyboard and I'm trying to set a constraint for the minimum size of my window (the view), but now matter what I do the constraint window is always grayed out, how do I go about this?

So I have this program that displays events on the window using NSWindow and a NSTextField. Basically it tracks the mouse position and the keyboard state. I created a simple class named MyEventWindow: // // MyEventWindow.h // AppTest #ifndef MyEventWindow_h #define MyEventWindow_h @interface MyEventWindow : NSWindow { } @property(nonatomic, strong) NSTextField* label; @property(nonatomic, strong) NSString* labelText; - (BOOL)windowShouldClose:(id)sender; - (instancetype) init; - (void) setLabelText:(NSString *)labelText; @end @implementation MyEventWindow -(instancetype) init { self = [super initWithContentRect:NSMakeRect(100, 100, 300, 300) styleMask:(NSWindowStyleMaskTitled | NSWindowStyleMaskClosable | NSWindowStyleMaskMiniaturizable | NSWindowStyleMaskResizable) backing:NSBackingStoreBuffered defer:NO]; if( !self ) { return nil; } [self setTitle: @"Event tracker"]; [self setIsVisible: YES]; _label = [[NSTextField alloc] initWithFrame:NSMakeRect(5, 100, 290, 100)]; [_label setBezeled: NO]; [_label setDrawsBackground: NO]; [_label setEditable: NO]; [_label setSelectable: YES]; NSFont *currentFont = [_label font]; NSFont *resizedFont = [NSFont fontWithName:[currentFont fontName] size:18]; NSFont *boldFont = [[NSFontManager sharedFontManager] convertFont:resizedFont toHaveTrait:NSFontBoldTrait]; // convert the bold font to have the italic trait NSFont *boldItalicFont = [[NSFontManager sharedFontManager] convertFont:boldFont toHaveTrait:NSFontItalicTrait]; [_label setFont:boldItalicFont]; [_label setTextColor:[NSColor colorWithSRGBRed:0.0 green:0.5 blue:0.0 alpha:1.0]]; // attach label to the damn window [[self contentView] addSubview: _label]; return self; } -(BOOL)windowShouldClose:(id)sender { return YES; } -(void) setLabelText:(NSString *)newText { [_label setStringValue: newText]; } @end #endif /* MyEventWindow_h */ Then in the main file I try to handle event loop manually: // // main.m #import <Cocoa/Cocoa.h> #import "MyEventWindow.h" NSString* NSEventTypeToNSString(NSEventType eventType); NSString* NSEventModifierFlagsToNSString(NSEventModifierFlags modifierFlags); int main(int argc, char* argv[]) { @autoreleasepool { [NSApplication sharedApplication]; MyEventWindow* eventWindow = [[MyEventWindow alloc] init]; [eventWindow makeKeyAndOrderFront:nil]; NSString* log = [NSString string]; // my own message loop [NSApp finishLaunching]; while (true) { @autoreleasepool { NSEvent* event = [NSApp nextEventMatchingMask:NSEventMaskAny untilDate: [NSDate distantFuture] inMode:NSDefaultRunLoopMode dequeue:YES]; log = [NSString stringWithFormat:@"Event [type=%@ location={%d, %d} modifierFlags={%@}]", NSEventTypeToNSString([event type]), (int)[event locationInWindow].x, (int)[event locationInWindow].y, NSEventModifierFlagsToNSString([event modifierFlags])]; //NSLog(@"log: %@", log); [eventWindow setLabelText: log]; [NSApp sendEvent:event]; //[NSApp updateWindows]; // redundant? } } } return 0; } NSString* NSEventTypeToNSString(NSEventType eventType) { switch (eventType) { case NSEventTypeLeftMouseDown: return @"LeftMouseDown"; case NSEventTypeLeftMouseUp: return @"LeftMouseUp"; case NSEventTypeRightMouseDown: return @"RightMouseDown"; case NSEventTypeRightMouseUp: return @"RightMouseUp"; case NSEventTypeMouseMoved: return @"MouseMoved"; case NSEventTypeLeftMouseDragged: return @"LeftMouseDragged"; case NSEventTypeRightMouseDragged: return @"RightMouseDragged"; case NSEventTypeMouseEntered: return @"MouseEntered"; case NSEventTypeMouseExited: return @"MouseExited"; case NSEventTypeKeyDown: return @"KeyDown"; case NSEventTypeKeyUp: return @"KeyUp"; case NSEventTypeFlagsChanged: return @"FlagsChanged"; case NSEventTypeAppKitDefined: return @"AppKitDefined"; case NSEventTypeSystemDefined: return @"SystemDefined"; case NSEventTypeApplicationDefined: return @"ApplicationDefined"; case NSEventTypePeriodic: return @"Periodic"; case NSEventTypeCursorUpdate: return @"CursorUpdate"; case NSEventTypeScrollWheel: return @"ScrollWheel"; case NSEventTypeTabletPoint: return @"TabletPoint"; case NSEventTypeTabletProximity: return @"TabletProximity"; case NSEventTypeOtherMouseDown: return @"OtherMouseDown"; case NSEventTypeOtherMouseUp: return @"OtherMouseUp"; case NSEventTypeOtherMouseDragged: return @"OtherMouseDragged"; default: return [NSString stringWithFormat:@"%lu", eventType]; } } NSString* NSEventModifierFlagsToNSString(NSEventModifierFlags modifierFlags) { NSString* result = @""; if ((modifierFlags & NSEventModifierFlagCapsLock) == NSEventModifierFlagCapsLock) result = [result stringByAppendingString:@"CapsLock, "]; if ((modifierFlags & NSEventModifierFlagShift) == NSEventModifierFlagShift) result = [result stringByAppendingString:@"NShift, "]; if ((modifierFlags & NSEventModifierFlagControl) == NSEventModifierFlagControl) result = [result stringByAppendingString:@"Control, "]; if ((modifierFlags & NSEventModifierFlagOption) == NSEventModifierFlagOption) result = [result stringByAppendingString:@"Option, "]; if ((modifierFlags & NSEventModifierFlagCommand) == NSEventModifierFlagCommand) result = [result stringByAppendingString:@"Command, "]; if ((modifierFlags & NSEventModifierFlagNumericPad) == NSEventModifierFlagNumericPad) result = [result stringByAppendingString:@"NumericPad, "]; if ((modifierFlags & NSEventModifierFlagHelp) == NSEventModifierFlagHelp) result = [result stringByAppendingString:@"Help, "]; if ((modifierFlags & NSEventModifierFlagFunction) == NSEventModifierFlagFunction) result = [result stringByAppendingString:@"Function, "]; return result; } in main I added a second @autoreleasepool inside the while loop it seemed to decrease memory usage significanly, however if I keep moving my mouse a lot the memory usage will still increase. I don't think this should be happening since the labelText is being destroying and recreated each iteration, is something wrong with my code? Why do I have a memory leak here? Any feedback regarding the code is also appreciated Cheers

The performance of the PrintCore API on macOS Sequoia system has significantly deteriorated. When switching between page options in the print dialog, the application hangs. It can be observed through Instruments that the execution time of PrintCore() is higher on the Sequoia system than on the Sonoma system. 479.00 ms 17.0% 0 s PMBaseObject::PMBaseObject(char const*) 456.00 ms 16.2% 0 s PMBaseObject::~PMBaseObject()

I'm using NSTextTable to format panels of stand-out text within body text. Paragraphs within the panel are handled as individual NSTextTableBlocks within the table. Each block is added to the NSMutableParagraphStyle that is part of the attributed string within the block's attributes. That's all fine and it works. But... Occasionally I see undrawn lines within the panel. These disappear (or sometimes appear) when the parent window (and thus the NSTextView holding the rendered attributed string) is resized. Lines do not always appear, and when they do they are not always in the same place. The height of the gap varies. I see this behaviour with these panels and with tables. What's common to both cases is not only the use of NSTextTable and NSTextTableBlock etc., but crucially (I think) the use of block margins. If I disable margins (which looks OK for the panels, but isn't right for tables), the problem disappears. So, a bug or (more likely) I'm missing a key part of view rendering or margin set up. But what? Code here: https://github.com/smittytone/PreviewMarkdown/blob/930f5f32aa0b3b77ec3f4f53436a79e10bb26f18/Markdown%20Previewer/Styler.swift#L882 Running 14.6.1 on an M3. I'm using TextKit 1 because I'm using an NSLayoutManager subclass to override certain text underlines (not used in panels as outlined above, or tables).

In the recent MacOS Sequoia Beta 3 NSTextAttachment initialized with custom data and an Image cell as attachmentCell are shown as a file icon istead of the image cell. I am creating a NSAttributedString and showing it in NSTextView like this: NSTextAttachment *attachment = [[NSTextAttachment alloc] initWithData:[text dataUsingEncoding:NSUTF8StringEncoding] ofType:nil]; attachment.attachmentCell = [[NSTextAttachmentCell alloc] initImageCell:img]; NSMutableAttributedString *res = [[NSMutableAttributedString alloc] initWithAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]]; ...

I created a simple application which displays a window with a sample text and I'm supposed to use an alert when the user chooses to close the application, if he presses ok in the alert the application will close, if he presses cancel it goes on. So pretty simple code, I have a window class: // // MyWindow.h // AppTest // // Created by sanya on 11/09/24. // #ifndef MyWindow_h #define MyWindow_h @interface Window : NSWindow { NSTextField* label; } - (instancetype)init; - (BOOL)windowShouldClose:(id)sender; @end @implementation Window -(instancetype)init { label = [[[NSTextField alloc] initWithFrame:NSMakeRect(5, 100, 290, 100)] autorelease]; [label setStringValue:@"Hello, World!"]; [label setBezeled:NO]; [label setDrawsBackground:NO]; [label setEditable:YES]; [label setSelectable:YES]; [label setTextColor:[NSColor colorWithSRGBRed:0.0 green:0.5 blue:0.0 alpha:1.0]]; [label setFont:[[NSFontManager sharedFontManager] convertFont:[[NSFontManager sharedFontManager] convertFont:[NSFont fontWithName:[[label font] fontName] size:45] toHaveTrait:NSFontBoldTrait] toHaveTrait:NSFontItalicTrait]]; [super initWithContentRect:NSMakeRect(0, 0, 300, 300) styleMask:NSWindowStyleMaskTitled | NSWindowStyleMaskClosable | NSWindowStyleMaskMiniaturizable | NSWindowStyleMaskResizable backing:NSBackingStoreBuffered defer:NO]; [self setTitle:@"Hello world (label)"]; [[self contentView] addSubview:label]; [self center]; [self setIsVisible:YES]; return self; } - (BOOL)windowShouldClose:(id)sender { BOOL bClose = NO; CFOptionFlags responseFlags = 0; // Display the alert CFUserNotificationDisplayAlert( 0, kCFUserNotificationNoteAlertLevel, NULL, NULL, NULL, CFSTR("Alert Title"), CFSTR("This is a message displayed in the alert."), CFSTR("OK"), CFSTR("Cancel"), NULL, &responseFlags ); if (responseFlags == kCFUserNotificationDefaultResponse) { NSLog(@"User clicked OK"); bClose = YES; } else if (responseFlags == kCFUserNotificationAlternateResponse) { NSLog(@"User clicked Cancel"); } if( bClose ) [NSApp terminate:sender]; return bClose; } @end #endif /* MyWindow_h */ And in the main function I just initialize it: int main(int argc, const char * argv[]) { [NSApplication sharedApplication]; [[[[Window alloc] init] autorelease] makeMainWindow]; [NSApp run]; } It seems to work but if click 'Cancel' on the dialog , xcode gives me the following warning: CLIENT ERROR: TUINSRemoteViewController does not override -viewServiceDidTerminateWithError: and thus cannot react to catastrophic errors beyond logging them So i'm obviously not doing this in the correct way, how can I fix this? Also, any feedback on this code as a whole is highly appreciated.

Hello, I want to subclass NSDocumentController, but I could not find the information in Apple document how to subclass. According to ChatGPT, it can be instantiated by [MyDocumentController sharedDocumentController]; before NSApplicationMain() as the following code. It seems working well in my test environment. int main(int argc, const char * argv[]) { [MyDocumentController sharedDocumentController]; NSApplicationMain(argc, argv); } But, I am not sure whether it is officially correct to instantiate so early (before calling NSApplicationMain). Is there any official information what is correct way to instantiate subclass of NSDocumentController?

I have a SwiftUI View containing a PDFView from PDFKit (via NSViewRepresentable). When setting a new PDFDocument the view flashes briefly with the background color before displaying the new document. Curiously the flashing is vastly reduced (but not eliminated) by calling layoutDocumentView() which should already be called from setDocument according to its documentation. struct SheetView: NSViewRepresentable { var pdf: PDFDocument? func makeNSView(context: Context) -> PDFView { let pdfView = PDFView() pdfView.displaysPageBreaks = false pdfView.displayMode = .singlePage pdfView.pageShadowsEnabled = false pdfView.autoScales = true return pdfView } func updateNSView(_ pdfView: PDFView, context: Context) { if pdf != pdfView.document { pdfView.document = pdf pdfView.layoutDocumentView() // reduces flashing but does not eliminate it } } }

Hello, while app icon is shown in 'Targets' app icon is not shown in 'alert panel' What is wrong? Best regards Gerhard

I have an NSTextLayoutManager set up with NSTextContentStorage and NSTextContainer. To work out the height of the content, I call the method updateContentSizeIfNeeded() which contains the code textLayoutManager.enumerateTextLayoutFragments(from: textLayoutManager.documentRange.endLocation, options: [.reverse, .ensuresLayout]) { layoutFragment in height = layoutFragment.layoutFragmentFrame.maxY return false } The first time this is called, it returns the correct height. Then I add a new character to the start of the NSTextContentStorage like so textContentStorage.performEditingTransaction { storage.replaceCharacters(in: NSRange(location:0, length: 1), with: "a") } textLayoutManager.ensureLayout(for: textLayoutManager.documentRange) textLayoutManager.textViewportLayoutController.layoutViewport() updateContentSizeIfNeeded() This time, the height returned is ~600px too big. The state of the NSTextLayoutFragment is set to layoutAvailable The next time I add a character to textContentStorage using the same code above, the height returned is correct again. I can work around this by calling enumerateTextLayoutFragments from the start of the document and not in reverse, then ignoring all fragments except the last one, but I don't know if that's the correct way to do it, or if I should be doing something else

Hello. What API or framework to use to simulate a mouse click on an iPad connected as an external display? An iPad connected to the Mac via USB in a mode "Linked keyboard and mouse". What is the way to simulate a mouse click at a specific coordinate at such a display? So far I tried to simulate a click with CGEvent like so if let eventDown = CGEvent(mouseEventSource: source, mouseType: .leftMouseDown, mouseCursorPosition: point, mouseButton: .left), let eventUp = CGEvent(mouseEventSource: source, mouseType: .leftMouseUp, mouseCursorPosition: point, mouseButton: .left) { eventDown.post(tap: .cghidEventTap) usleep(500_000) eventUp.post(tap: .cghidEventTap) } but it seems it does not work even on the main display. I set the point to the coordinate outside of the app window so that on a click another app should be focused but it does not happen on a simulated click. I also tried to find a way to get a mouse coordinate on the external screen with addLocalMonitorForEvents. If I listen for the event NSEvent.addLocalMonitorForEvents(matching: [.mouseMoved]) { event in debugPrint("NSEvent.mouseLocation:", NSEvent.mouseLocation) return event } it only works when the cursor is on the main screen and stops reporting as soon as the mouse enters the iPad. So, any advice is welcomed on which direction I should look.

The new window resizing and placement feature of macOS Sequoia is not working in my application, and I don't know why. What's worse, I haven't consulted any relevant documents.

I am trying to get the list of printers using NSPrinter.printerNames, but it doesn't return any items. static func getPrinterList() -> [(name: String, isAvailable: Bool)] { let printerNames = NSPrinter.printerNames return printerNames.map { name in let isAvailable = NSPrinter(name: name) != nil return (name: name, isAvailable: isAvailable) } } The printerNames is a empty string array. I checked the settings for printers and screens, and there is a printer device listed. I need to set something else?

I have two NSTextField as an accessoryView of NSSavePanel. When I try to change focus in between them with a caps lock on the whole panel will crash. This will also happen when NSTextField if focused with caps lock on and i press cmd+tab (app switching). This happens on Sonoma + Sequoia beta. On top I have noticed editing NSTextField in accessoryView is completely broken on Sonoma and I can only edit it ONLY when the textfiled is using bindings. I am trying to find a workaround for the caps lock indicator being displayed. The only idea I have ATM is to observe NSApp.windows and look for TUINSWindow and force close it when it's visible. Is there any other workaround to prevent this crash? https://youtu.be/BCVjZH7684U Sample code: import Cocoa class ViewController: NSViewController { let savePanel = NSSavePanel() override func viewDidLoad() { super.viewDidLoad() let view = NSGridView(views: [[NSTextField(string: "111111")], [NSTextField(string: "22222222")]]) savePanel.accessoryView = view } override func viewWillAppear() { savePanel.runModal() } } Crash report: Cannot remove an observer <TUINSCursorUIController 0x600001844340> for the key path "visible" from <NSSavePanel 0x10ff05200> because it is not registered as an observer.

Our MacOS application has a single window which is occupied by an NSView-derived view. It's been working for the last ten years or so, but when using the Sonoma beta, window updates are badly broken. We rely on using setNeedsDisplayInRect to redisplay any portions of the view that need to be redisplayed, but no matter how small a rectangle we specify, the entire window is repainted with the background colour before our drawRect implementation is called. We already provide an overload of isOpaque in our view which returns true, and in the past this was effective for suppressing the background fill, but it no longer seems to work (although I can confirm that it is still called along the way). I've attached an image that shows an example of how a sample window looks after resizing (which is correct) and then what it looks like after using setNeedsDisplayInRect to invalidate the region occupied by the button in the centre. I've explicitly set the NSWindow background colour to blue to make it more obvious : Is it still possible to inhibit the background fill? Repainting the entire view for every update is not really an option for us, for performance reasons

I need to draw an attributed string into a given rectangle. The string's height should be the same as the rectangle's height. This should work with any font a user chooses. To make it a bit more complicated, the string should also fill the rect if it consists only of uppercase characters or only of lowercase characters. I am using NSLayoutManager to find the "best" font size for the selected font and the given recht and it works quite good with some fonts but with others it doesn't. Seems like the computed font size is always a bit too small and for some fonts it seems like the baseline must be corrected. Unfortunately I didn't find a way to calculate a baseline offset that really works with any font. I attached some sample images showing the issue. Just posting this to make sure I am not running in the complete wrong direction. Any help would be highly appreciated. Thanks!

Our app supports only portrait mode. And in some cases, the status bar moves horizontally, as shown in the video below. We have confirmed that this problem does not appear in OS versions 15.3.1 and lower. The problem occurs on OS 16 and 17. https://youtu.be/CiR5LcoBI5c At the point when the problem appears, the code simply subscribes to data through the interval scheduler. The code is below: At that point, set autoUpdate to true. private let autoUpdateTimer = Observable<Int>.interval(.seconds(20), scheduler: MainScheduler.asyncInstance) private var autoUpdate = BehaviorRelay<Bool>(value: false) autoUpdateTimer .withLatestFrom(autoUpdate) .filter { $0 } .withLatestFrom(Observable.combineLatest(deviceSeq,currentChannel,channel) .map { ($0.0, $0.1, 1, $0.2?.property?.unitCount ?? 1) } .flatMap(dependency.usecase.pubAutoStatus) .subscribe().disposed(by: disposeBag) I would appreciate any feedback on how I can resolve this.

I am use XCode 15.2 and macOS SDK 14.2. I placed an NSView inside the NSClipView of an NSScrollView, the NSView is smaller than the NSClipView, always centered. On Ventura, regardless of whether clipsToBounds is set, the bounds and visibleRect of the NSView are the same. However, on Sonoma, even after overriding -(BOOL)clipsToBounds { return YES; }, the bounds is correct, but the visibleRect (the red rect) is still the same size as the NSClipView, results in the text is not clipped. Am I missing something or doing something wrong? How can I make the visibleRect of the NSView consistent with its bounds?
