I have an object that is an NSRuleEditorDelegate for an NSRuleEditor whose nestingMode is NSRuleEditorNestingModeList. There are 8 different possible criteria. Each criterion is optional but at least 1 is required (ruleEditor.canRemoveAllRows = NO). Each criterion should only be added once. How can I limit adding a criterion for a row if it is already in the editor at a different row? Thanks!

I am using NSMenuToolbarItem to show a drop-down menu in my NSToolbar. This works as expected when creating an NSMenu beforehand and assign it to the menu property of NSMenuToolbarItem. However, my menu needs to be built dynamically when the user clicks the dropdown button. To do that, I am using NSMenuDelegate. When creating the menu in the menuNeedsUpdate of the delegate, the first menu item isn't shown to the user. Why? Menu when using delegate: Menu when pre-assigning menu: I also cannot just add a placeholder menu item at the start of the NSMenuToolbarItem as all menu items do show in the overflow menu. Example code: import Cocoa class AppDelegate: NSObject, NSApplicationDelegate, NSToolbarDelegate, NSMenuDelegate { var window: NSWindow! func applicationDidFinishLaunching(_ aNotification: Notification) { window = NSWindow(contentRect: NSRect(x: 0, y: 0, width: 400, height: 300), styleMask: [.titled, .closable, .resizable], backing: .buffered, defer: false) window.makeKeyAndOrderFront(nil) let toolbar = NSToolbar(identifier: "MainToolbar") toolbar.delegate = self window.toolbar = toolbar } func toolbarAllowedItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [NSToolbarItem.Identifier("item1"), NSToolbarItem.Identifier("item2")] } func toolbarDefaultItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [NSToolbarItem.Identifier("item1"), NSToolbarItem.Identifier("item2")] } func toolbar(_ toolbar: NSToolbar, itemForItemIdentifier itemIdentifier: NSToolbarItem.Identifier, willBeInsertedIntoToolbar: Bool) -> NSToolbarItem? { let item = NSMenuToolbarItem(itemIdentifier: itemIdentifier) if itemIdentifier == NSToolbarItem.Identifier("item1") { let menu = NSMenu() fillMenuWithItems(menu) item.menu = menu } else if itemIdentifier == NSToolbarItem.Identifier("item2") { item.menu = NSMenu() item.menu.delegate = self } return item } func menuNeedsUpdate(_ menu: NSMenu) { menu.removeAllItems() fillMenuWithItems(menu) } func fillMenuWithItems(_ menu: NSMenu) { menu.addItem(NSMenuItem(title: "Option 1", action: nil, keyEquivalent: "")) menu.addItem(NSMenuItem(title: "Option 2", action: nil, keyEquivalent: "")) } }

After each macOS update come new annoying log messages. So after updating to Sonoma and Xcode 16, I see the following logged in the Xcode console whenever my app shows an NSPredicateEditor. Failed to find localization for values: All, of the following are true I tried setting the "localize" attribute to "never" in the attributes inspector of the corresponding menu/text fields from interface builder, to no avail. Any suggestions ?

In Monterey, when a user was at the top of a ScrollView implemented inside of a NSHostingController's view (that was itself embedded in a window with a NSToolbar), the window's toolbar background would be hidden until the user scrolled from the top. In Ventura, this behavior is different, with the toolbar's background visible all of the time unless a traditional NSScrollView is used (which means no SwiftUI). Is there the ability to change this behavior within SwiftUI some how now?

In the WWDC22 talk "What's new in TextKit and text views" (https://developer.apple.com/videos/play/wwdc2022/10090?time=408), it was announced (at minute 6:45) that TextKit 2 & NSTextList is supposed to be working on both UIKit and AppKit. While NSTextLists are correctly rendering on iOS, they are not working on macOS. The paragraphs aren't inset and the numbers/bullets do not render in front of the list items. Any help? let textView = NSTextView(frame: self.view.bounds) textView.translatesAutoresizingMaskIntoConstraints = false self.view.addSubview(textView) let safeArea = view.safeAreaLayoutGuide NSLayoutConstraint.activate([ textView.topAnchor.constraint(equalTo: safeArea.topAnchor), textView.bottomAnchor.constraint(equalTo: safeArea.bottomAnchor), textView.leadingAnchor.constraint(equalTo: safeArea.leadingAnchor), textView.trailingAnchor.constraint(equalTo: safeArea.trailingAnchor) ]) let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.textLists = [NSTextList(markerFormat: NSTextList.MarkerFormat("{decimal}."), options: 0)] let attributedText = NSMutableAttributedString("Item 1\nItem 2\nItem 3\nItem 4f") attributedText.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: attributedText.length)) textView.textStorage?.setAttributedString(attributedText)

When using the new ‘addSymbolEffect’ effect method on NSImageView with the ‘.rotate.byLayer’ parameter with an applicable SF Symbol 6 symbol, the resulting animation is not completely as expected, to say it mildly. This is the code line I use: imageView.addSymbolEffect(.rotate.byLayer, options: .repeat(.continuous), animated: true) The correct layer rotates around the correct anchor point, but the whole image is moving up and down. The same code with the same symbol in iOS 18 beta runs perfectly. Does anyone know how to get this new rotate API correctly working in macOS 15 beta? In case an Apple engineer reads this: FB13916874 contains example projects for macOS (wobbling rotation) and iOS (perfect rotation), and a screen recording what I see in macOS 15 beta.

Bit of a stream of consciousness below. I discovered after writing all that that I needed to switch width & height when setting values, and print landscape. That gets things to print as expected. But I really need to be able to set the Brother's notion of tape width in the Basic Options portion of the print panel. I've got this Brother QL-800 USB label printer that takes spools of either die-cut labels, or continuous paper of a given width. It can cut between labels or the continuous paper at any point. My app is intended to print small labels for small parts drawers. The app has a DB of parts, and I want to print dozens of unique labels of a specific height and width. Ideally, you'd set things up once, and then print one or more specific part labels without further UI interaction. The NSPrintPanel is far too complex, and allows the user to ***** things up, so I'd like to forego it altogether. I've written some simple code that does succeed in printing via the NSPrintPanel, but it’s positioning the text ultimately incorrectly. I can't figure out how to properly size a view to print a label. I can get an NSPrintInfo object that knows the label printer is selected (e.g. it shows the right name for NSPrintInfo.printer.name). But it states the paperSize is (612.0, 792.0), which if I assume 72 ppi, comes out to 8.5" x 11", which this paper clearly is not. func printLabel() { Task { let printInfo = NSPrintInfo() let printer = printInfo.printer print("Paper size: \(printInfo.paperSize)") // printInfo.paperSize = CGSize(width: 47 / 25.4 * 72.0, height: 12.0 / 25.4 * 72.0) printInfo.topMargin = 0.0 printInfo.bottomMargin = 0.0 printInfo.leftMargin = 0.0 printInfo.rightMargin = 0.0 printInfo.orientation = .landscape printInfo.isHorizontallyCentered = false printInfo.isVerticallyCentered = false printInfo.scalingFactor = 1.0 let view = NSHostingView(rootView: createLabelPrintView()) view.frame.size = CGSize(width: 25 / 25.4 * 72.0, height: 12.0 / 25.4 * 72.0) let op = NSPrintOperation(view: view, printInfo: printInfo) op.showsPrintPanel = true op.showsProgressPanel = true op.printPanel.options.insert(.showsPaperSize) op.printPanel.options.insert(.showsOrientation) op.run() } } @ViewBuilder func createLabelPrintView() -> some View { VStack(spacing: 0) { Text("Line 1") Text("Line 2") } .padding(0) } If I set the pageSize explicitly (uncommenting the line above), The printer offers a long list of available sizes (although none I've found corresponds to the 0.47"/12 mm x continuous spool). By the way, it never remembers the size I selected, and always reverts to 8.5 x 11, which it will then refuse to print, hanging in Print Center with an error about mismatched page sizes. I don’t know why the available page sizes have multiple sizes that don’t seem to match. E.g. 0.47" In the printer’s “Basic Options,” it shows the notion of a Width that's "not found," if I use a custom size: I don't really understand where those printer options can be found and set. Hmm, maybe I found a clue: I ran an NSPrintPanel by itself and examined the NSPrintInfo afterward: let panel = NSPrintPanel() panel.options.insert(.showsPaperSize) panel.options.insert(.showsOrientation) let result = await panel.beginSheet(using: printInfo, on: NSApplication.shared.windows.first!) print("Result: \(result)") print("Paper size: \(printInfo.paperSize)") print("Settings: \(printInfo.printSettings)") Paper size: (283.44000244140625, 82.08000183105469) Settings: { "AP_D_InputSlot" = ""; BrAutoTapeCut = ON; BrBiDiPrint = ON; BrBrightness = 0; BrContrast = 0; BrCutAtEnd = ON; BrCutLabel = 1; BrHalftonePattern = BrErrorDiffusion; BrMargin = "3.0"; BrMultiColor = BrMultiColorMonochrome; BrRedLevel = 0; BrRemoveBlkSpace = OFF; BrResolution = BrSpeed300x300dpi; BrTapeLength = "69.1"; ColorModel = Gray; Duplex = None; PaperInfoIsSuggested = 0; Resolution = 300x300dpi; "com_apple_print_DialogDismissedBy" = Print; "com_apple_print_DocumentTicket_PMSpoolFormat" = "application/pdf"; "com_apple_print_PDEsUsed" = "Printer Options"; "com_apple_print_PageToPaperMappingMediaName" = 29mm; "com_apple_print_PageToPaperMappingType" = 1; "com_apple_print_PrintSettings_PMCopies" = 1; "com_apple_print_PrintSettings_PMCopyCollate" = 1; "com_apple_print_PrintSettings_PMDestinationType" = 1; "com_apple_print_PrintSettings_PMDuplexing" = 1; "com_apple_print_PrintSettings_PMFirstPage" = 1; "com_apple_print_PrintSettings_PMLastPage" = 2147483647; "com_apple_print_PrintSettings_PMPageRange" = ( 1, 2147483647 ); "com_apple_print_ticket_type" = "com.apple.print.PrintSettingsTicket"; "com_apple_print_totalPages" = 2147483647; } It has added a bunch of Br-prefixed keys that clearly correspond to some of the options in the UI. But I'm not sure if I can set those programmatically and get things to print the way I expect. And I don't see anything for tape width. How do I get an NSPrintPanel to show the preview without an NSPrintOperation? I want to react to any changes the user might make before things go to print.

I have a simple cocoa project, it has the default files like AppDelegate.m, AppDelegate.h , ViewController.h and ViewController.m what I want is to set the Window title to the dimension of the current window and update it as the user resizes it. My Storyboard has an Application Scene, a Window Controller Scene and a test Scene which contains my view: how do I go about this? should my ViewController or AppController implement NSWindowDelegate ?

We have a xib file that contains a toolbar with some items in it. The toolbar has an IBOutlet defined in its files owner. Before macOS 15 - we were able to reach the items in the toolbar by using the items property. The File Owner for the xib containing the toolbar is a NSViewController e.g. @IBOutlet var theToolbar: NSToolbar! required init?(coder: NSCoder) { super.init(coder: coder) Bundle.main.loadNibNamed("ToolbarDesign", owner: self, topLevelObjects:nil) } and then later in code... func getItems() { let items:[NSToolbarItem]? = mainRightToolbar?.items } Prior to macOS15 - items would contain the NSToolbarItems specified in the xib design. Now, in macOS 15 - the items array is not nil but doesn't contain any items either. What needs to be don't for macOS15 specifically to enable the items property of NSToolbar to work again?

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?

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 } } }
