I am seeking for this User Interface(UI) effect --> "Spotlight" a specific IBOutlet (Please see attached Image2.png below) for a week! Explain the "Spotlight" effect : I wish to create is effect similar to NSAlert or beginSheet effect which user cannot click or access the entire window/view until user trigger a button and it back to normal. The whole window/view will becoming darken or gray EXCEPT a specific button I allow my user to interact with. Yet, I found that there is no any trick to create such effect neither in XIB file nor objective-c code. This is urgent for me. Eagerly waiting for your reply. Much Appreciated.

I have created my first app with python using py2app and it build my app successfully but when I try to open it, it crash but when I open it's package and run it from this path: myapp.app/contents/macos/myapp it open console and run my app correctly without any error. I can't understand how to read this kind of mac errors. I will be happy if you can help me with that: Error Text

Hello, I‘m trying to create an app with one NSPopUpButton and two NSTextFields. The first control is the NSPopUpButton and I want to make it the initialFirstResponder. When the app starts, it always skips the popUpButton and the focus is on the first textField. I already tried to subclass the popUpButton and to override canBecomeKeyView. Maybe someone has a hint. Thanks.

Below is a custom view class: class MyView: NSView { var xloc = 0.0 var yloc = 0.0 var width = 400.0 var height = 200.0 var myRect = NSRect(x: 0.0, y: 0.0, width: 400.0, height: 200.0) ... override func draw(_ dirtyRect: NSRect) { let myColor = NSColor(red: 1.0, green: 1.0, blue: 1.0, alpha: self.alpha) myColor.setFill() dirtyRect.fill() self.myRect = NSRect(x: self.xloc, y: self.yloc, width: self.width, height: self.height) self.setNeedsDisplay(myRect) self.myRect.fill(using: NSCompositingOperation.clear) } The view controller has a keyDown handler as follows: override func viewDidLoad() { super.viewDidLoad() view.window?.backgroundColor = NSColor.white NSEvent.addLocalMonitorForEvents(matching: .keyDown) { self.keyDown(with: $0) return $0 } } override func keyDown(with event: NSEvent) { let theView = self.view as! MyView if event.keyCode == 126 { NSLog("Increasing Y coordinate") theView.yloc = theView.yloc + 10 self.view.display() } } Below is the AppDelegate.swift's content: func applicationDidFinishLaunching(_ aNotification: Notification) { let window = NSApplication.shared.windows.first window?.isOpaque = false window?.backgroundColor = NSColor.clear window?.ignoresMouseEvents = true window?.toggleFullScreen(self) window?.collectionBehavior = NSWindow.CollectionBehavior.fullScreenPrimary let screenFrame = NSScreen.main?.frame window?.setFrame(screenFrame!, display: true) let myView = MyView() window?.contentView = myView } The rectangular hole is seen on the screen initially The above handler is called whenever I press the up arrow key. The self.view.display() in turn calls the draw() method on the view. But the NSRect is not drawn in the new position. Request you to please help me with this. The expected result is to move (or rather redraw) the NSRect based on the keyboard up arrow click Currently incomplete code is at: https://github.com/suchindrac/hide_pane_mac

When I hover the mouse over the NSTextAttachment image inside the UITextview, it should show this option to MarkUp. All native app including Notes, TextEditor, Mail have this behaviour: I think, by default, NSTextView will show the NSSharingServicePicker button when you hover over an image inside the text view. That’s true even for custom image-based NSTextAttachments in the attributed string. But it is not showing the button for UITextview in MacCatalyst. Also NSSharingService class is limited to MacOS only. Are there any alternative way to achieve this in MacCatalyst?

What is the Objective C equivalent of the command line diskutil unmount force ?

I have a DLP-Link 3D projector which I'd like to make use of by means of a hand-made player. So far in my project: A class MovieView : NSView within a NSWindow, with stub drawing codes. I know that, if I place drawing codes in the func draw(...) function, then NSGraphicsContext.current will be set up for me to use. But I'm drawing from a high-priority thread (the DisplayLink), so I obviously have to set it up myself. How should I do that in Swift?

I was able to implement drag and drop with NSTableViewDiffableDataSource by subclassing and adding the missing methods. It works but the draggingSession willBeginAt method is never called so I can't provided a custom preview to the dragging. Any tips from AppKit developers or Apple engineers? class ListCoordinator: NSTableViewDiffableDataSource<String, Int>, NSTableViewDelegate {     @objc func tableView(_ tableView: NSTableView, pasteboardWriterForRow row: Int) -> NSPasteboardWriting? {         return NSPasteboardItem(pasteboardPropertyList: row.formatted(), ofType: .string)     }     @objc func tableView(_ tableView: NSTableView, validateDrop info: NSDraggingInfo, proposedRow row: Int, proposedDropOperation dropOperation: NSTableView.DropOperation) -> NSDragOperation {         return .move     }     @objc func tableView(_ tableView: NSTableView, acceptDrop info: NSDraggingInfo, row: Int, dropOperation: NSTableView.DropOperation) -> Bool { ...         return true     }          @objc func tableView(_ tableView: NSTableView, draggingSession session: NSDraggingSession, willBeginAt screenPoint: NSPoint, forRowIndexes rowIndexes: IndexSet) {         // NEVER CALLED     }      }

I'm getting some Crash Reports for an app of mine that's on the Mac App Store.

When I tried this, the app crashed immediately with a requirement to use NSTextContentStorage subclass

I recently updated my sandboxed application to the MacOS 12 target. Among deprecation, there is the allowedFileTypes method for NSOpenPanel/NSSavePanel, replaced with allowedContentTypes. I updated my document opening and importing methods to reflect this change. For example, to import a CSV or JSON file, I coded: myPanel.allowedContentTypes = [NSArray arrayWithObjects:UTTypeJSON, UTTypeCommaSeparatedText, UTTypeTabSeparatedText, [UTType typeWithIdentifier: @"org.openxmlformats.spreadsheetml.sheet"], nil] ; All these UTTypes are described in the "Imported Type UTIs" section of the app's Info.plist. Unfortunately, it is impossible to select any of Json, Csv or Xlsx file in the NSOpenPanel since I made these changes to be in line with MacOS12 requirements. Worse, I cannot open my own file format with its own UTI (described in Info.plist too)! The only way to open/import is to set myPanel.allowOtherFileTypes to TRUE, and to remove any code referring to allowedContentTypes. What is quite strange is that exporting works correctly after updating. My spotlight plugin works also (for my file format)… Something I missed? Help welcome as my app became useless since I made these changes, and I use it every day for my work (and improving it before launching it on the Appstore)

Looking for a Cocoa example/tutorial in Objective C, on how to create a 400x90 pixel panel with outlets for a progress bar, textfield and a button (stop) to display temporarily while images are loading. I've added a WindowController + xib to the app's main storyboard but don't know how to use it to access the outlets in the progress panel.

Hi, I'm working on making a Document based app for MacOS using AppKit and I wanted the different documents to be displayed as tabs of the same window which after a lot of research I managed to do using this single line: windowController.window?.tabbingMode = .preferred which I added inside the makeWindowControllers function of my Document. I figured that in order to be able to style my tabs I should use this method: windowController.window?.tab.attributedTitle = ... But whatever I added after this = didn't do anything to my tabs. For example I tried this: windowController.window?.tab.attributedTitle = NSAttributedString(string: "Hello", attributes: [NSAttributedString.Key.backgroundColor: NSColor.red]) Weirdly, using this method: windowController.window?.tab.title = ... did work but is far more limited than the other one. Maybe I did something wrong in my implementation of the tabs but it seems to work properly when I run it, only the colors and fonts don't match what I'd like to make which is why I wanted to change them using the attributed title. Here's my full code for the function: override func makeWindowControllers() {     let storyboard = NSStoryboard(name: NSStoryboard.Name("Main"), bundle: nil)     if let windowController =         storyboard.instantiateController(             withIdentifier: NSStoryboard.SceneIdentifier("Document Window Controller")) as? NSWindowController {         addWindowController(windowController)         windowController.window?.tabbingMode = .preferred         windowController.window?.tab.attributedTitle = NSAttributedString(string: "hey", attributes: [NSAttributedString.Key.backgroundColor: NSColor.red])         // Set the view controller's represented object as your document.         if let contentVC = windowController.contentViewController as? ViewController {             contentVC.representedObject = content             contentViewController = contentVC         }     } } I would really appreciate some help on this issue! Thanks by advance, Cyprien

I created a custom keyboard layout with the app Ukelele, based on a built-in layout and thus using the original icon. However, the icon is not loaded as a template image in the Menu Bar. The result is that when a darker background image is used (or a dynamic background turns darker), the black part of the icon does not switch to white and all I see is a black square with the letters of the keyboard layout not readable: This was fine until 12.3 when flags were used as icons instead. Is this a bug and is there a way to workaround this?

I have an Objective-C macOS app which provides a service that provides unique services on selected text. This app has been for sale in the Mac App Store for several years. The app registers as service provider during 'appDidFinishLaunching' with: [[NSApplication sharedApplication] setServicesProvider:self]; When my service is invoked it uses the standard service method: (void)serviceName:(NSPasteboard *)pboard userData:(NSString *)userData error:(NSString **)error In the body of this standard service method the contents of the NSPasteboard (pboard) are examined and consumed by my app. - (void) kudosService:(NSPasteboard *)pboard userData:(NSString *)userData error:(NSString **)error; { if ([pboard pasteboardItems].count==0) { return; } NSPasteboardItem *pI = [pboard pasteboardItems][0]; NSLog(@"pI:%@",pI.types ); for (NSString *uti in pI.types) { NSLog(@"uti:%@ string:%@",uti, [pI stringForType:uti] ); } ... } Something has changed with Preview app; at this point I'm inclined to think the change occurred with version 11. Console output for Preview pI:( "public.utf8-plain-text", "public.rtf", "public.utf16-external-plain-text" ) uti:public.utf8-plain-text string:(null) uti:public.rtf string:(null) uti:public.utf16-external-plain-text string:(null) This is the output regardless of whether or not the user has a mere text selection OR has formally 'Cop(ied)' [Cmd-C] the text in the Preview window! Please NOTE if I open the exact same .pdf document in Safari and invoke the service from Safari I see the expected Console output: pI:( "public.utf8-plain-text" ) uti:public.utf8-plain-text string:The Best Gluten-Free Chocolate Cake When did this change in Preview behavior occur? Can anyone point me to some documentation, which I have obviously overlooked, that would shed some light on this matter!

Is there a simple way to create an NSFontCollection based on NSFontDescriptor querying to gather all installed/available fonts with a MATH table? It doesn't look like there's an attribute for that, but I don't know how else to search other than correlating with features like ssty, dtls, and flac.

I would like to be able to get either the key code or the characters/text from an NSEvent/KeyEvent. Absolutely no idea how to do this as the documentation I have found so far has been very limited. I believe I need to create an instance of NSEvent but I do not know how. My script is below. I am working on a speedrun macro for Minecraft. This script is fully functioning as is, but currently all it does is check if the control key has been pressed via checking the modifier flags of NSEvent. use framework "AppKit" use scripting additions global ca set ca to current application # you may change the following variables global seed set seed to "8398967436125155523" # do not change anything below this line to isModifierPressed(modifier) ((ca's NSEvent's modifierFlags()) / modifier as integer) mod 2 is equal to 1 end isModifierPressed repeat if isModifierPressed(ca's NSEventModifierFlagControl) then execute() delay 0.01 end repeat on execute() tell application "System Events" delay 0.1 keystroke tab delay 0.02 keystroke return delay 0.02 repeat 3 times keystroke tab delay 0.02 end repeat keystroke return delay 0.02 repeat 2 times keystroke tab delay 0.02 end repeat repeat 3 times keystroke return delay 0.02 end repeat repeat 4 times keystroke tab delay 0.02 end repeat keystroke return delay 0.02 repeat 3 times keystroke tab delay 0.02 end repeat keystroke seed delay 0.02 repeat 6 times keystroke tab delay 0.02 end repeat keystroke return end tell end execute
