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.

Platform: macOS 12.3.1 Xcode: 13.3 I had Xcode ARC turned ON. AppleScript should be declared like below. NSAppleScript *script = [[NSAppleScript alloc] initWithSource:strScript]; When call AppleScript, open "Monitor.app" app will observe some memory leak. I try to wrap AppleScript by autoReleasePool. Memery leak still exists @autoreleasepool { NSAppleScript *script = [[NSAppleScript alloc] initWithSource:strScript]; //script to do something } Is there other suggestion to do gabage collection to release memory?

Hi there,we are getting frequent questions from our user base when they cannot find options in the print dialog of our app because the details in NSPrintPanel are not expanded by default.Is there a way to always expand the details section programmatically to make it easier for our non-technical user base to find the app specific print settings..?Browsing the NSPrintPanel documentation didn't reveal anything obvious..Cheers,Jay

The PDFDocument class makes updating metadata attributes simple but appears to:Disallow arbitrary values for the /Producer attribute - the wite action substitutes an Apple string as the producerOffer no choice over the PDF version or the write format - it's 1.4, and compressed regardless of the original PDF formatAm I missing something simple in the PDFDocument class that will over-ride this behaviour?Is the PDFDocument structure archive conformant and, if so, to what level?Is it necessary to deal directly with CGPDFDocument to overcome these limitations?cheers,david

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?

Is there any particular reason why a WKWebView instance set as the contentView of a NSWindow would not display web content when the window is displayed using the runModalForWindow method of NSApplication?If I display the window using the showWindow method of NSWindowController, it displays correctly.If I replace the WKWebView instance with a WebView instance, the web content displays correctly whether the window is shown modally or not.In all cases I am calling loadRequest: in windowDidLoad.Bruce

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'm experimenting with the Accessibility API and I'm currently trying to interrogate the system wide accessibility element.According to AXUIElementCopyAttributeNames the system wide element has 4 attributes (AXRole, AXRoleDescription, AXFocusedUIElement & AXFocusedApplication).I can successfully use the following chunk of code to get the attribute value for the AXRole and AXRoleDescription elements but when I try to get the value of the AXFocusedUIElement or AXFocusedApplication attributes AXUIElementCopyAttributeValue returns kAXErrorCannotComplete.AXUIElementRef systemWideElement = AXUIElementCreateSystemWide(); CFStringRef attrName = kAXFocusedApplicationAttribute; CFTypeRef value = NULL; res = AXUIElementCopyAttributeValue(systemWideElement, attrName, &value); if (res != kAXErrorSuccess) NSLog(@"Failed to get element attribute %@ (%d)", attrName, (int)res); if (value) CFRelease(value);Does anybody know why AXUIElementCopyAttributeValue is returning kAXErrorCannotComplete / what I'm doing wrong?Thanks

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

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 now trying to add Drag &amp; Drop feature to my NSTableView which uses NSTableViewDiffableDataSource for its data source. However, I can't implement the methods for Drag &amp; Drop like tableView(:, acceptDrop:, row:, dropOperation:). My code looks like this: swift class MyViewController: NSViewController { private let tableView: NSTableView = {...}() private lazy var dataSource = MyDataSource(tableView: tableView) ... } class MyDataSource: NSTableViewDiffableDataSourceSection, Model { ...     override func tableView(_ tableView: NSTableView, draggingSession session: NSDraggingSession, willBeginAt screenPoint: NSPoint, forRowIndexes rowIndexes: IndexSet) { ...     } } Since NSTableViewDiffableDataSource implements NSTableViewDataSource protocol which provides Drag &amp; Drop methods, I thought the above overriding method would work but I got this error. Method does not override any method from its superclass What happened? And if this is expected, how can I implement Drag &amp; Drop with NSTableViewDiffableDataSource?
