Hi, I override the drawTickMarks() in NSSliderCell. However, I need to draw some text there and may have a little outside the NSSlider's boundary, so I got some clip in my result. I try to set the maskToBound to false by      self.controlView?.wantsLayer = true     self.controlView?.layer?.masksToBounds = false     self.controlView?.layer?.backgroundColor = CGColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 0.5) So I can clearly see the bounds of slider but the masksToBounds didn't work here. Does anybody know to make the masksToBounds work for my purpose? Thank you~~

Hi, I am not sure about the real reason of my case, when I use NSWindow of my window's base class, the options (Zoom, Move Window to Left Side of Screen, Move Window to Right Side of Screen, ... etc) that when I hover on the resize button are disabled. But when I change my window's base class to NSPanel, these options are enabled. What I want is disabling all options in the option menu and keeping zoom function only on the resize button. Are there some attribute that I can set to disable these options? Thank you~~ Eric

Hi I am using the NSCollectionView to provide the media preview & selection for user. I found the iPhoto application can highlight (with blue border) the selected photo that inside the selection rectangle when I drag mouse ( Didn't go mouse up state yet.) But I can't find the delegate in NSCollectionViewDelegate can help me to implement this feature? Are there any method I can use to implement this feature? I found the delegate shouldChangeItemsAt is called during mouse dragging but the index array is empty? Can I use some setting to make it give me the selected item's array? Thanks Eric

Hi, I am trying to build ffmpeg for Intel and M1 platform for my application. I got some problem, because when I put arm64 dylibs I got error that no x86_64 dylibs available. And I got arm64 dylibs not available when I put x86_64 dylibs. Can I combine these two set of dylibs into a single one then I don't need to change the dylibs on different platform? XCFramework or ?? Thank you. Eric

I have porting my existing application to support native M1, there a a lot of framework and library that I have already build for both platform. The strange result is when I archive the app on Intel machine. The binary work on Intel platform well. When I archive my application on M1 machine, the app can work on M1 well. But when I try to run app that build on M1 on Intel Machine, then I got the message said my app is damaged and can't be opened. The same situation got for build in Intel platform one. I try "lipo -archs" command on my app and I did get "x86_64 arm64" as result, so my app should already a universal app I guess. Does any body know are there some way to check what happened on my application? Thanks, any opinion will be appreciated ! Eric

My code was lived well recently. But today after I update my Xcode 13.1.( It ask me to install some components and I always click yes.) Then all code related to core graphic like this can't work now. Not only the code but also the constant like: kCGImagePropertyExifFlash is failed to be recognized too. Does anybody know what happened?  // Write Image CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef bitmapContext = CGBitmapContextCreate(     pBuffer,     imgInfo.nWidth,     imgInfo.nHeight,     8, // bitsPerComponent     4*imgInfo.nWidth, // bytesPerRow     colorSpace,     kCGImageAlphaNoneSkipLast);

I met a strange issue. I got error: dyld: Library not loaded: /usr/local/lib/mylib.dylib Reference from: ..... Reason: image not found I didn't suppose that I need to load library from /usr/local/lib, because it already included in my project. The lib is an embed lib of my project and this issue only happened on my M1 mini? I have try three devices even on MacOS 12.0.1 Then I found the "Runpath Search Paths" seems didn't work on M1 machine. All setting among three machine are the same. (The same source code). Even I use the absolute path on this setting on M1 machine didn't work while others two machine without any problem. Does anybody know what happened? Should I add additional setting on my M1 machine? ps: My project has two level, the problem happen on my second level project which is included in the first level project. I am not sure related to this or not?

Hi, I am trying the speech recognition API. For live recognition, I use SFSpeechAudioBufferRecognitionRequest It works fine in general. But when I try to use file recognition with SFSpeechAudioBufferRecognitionRequest I found that I can't find a way to cancel the recognition? Cancel or kill the request can't stop the call back from result handler. So I need to wait the recognition finish when I receive the result's isFinal flag is true. It make me a little inconvenient if I try to recognize a long audio file and finally decide to cancel the recognition. Are there some ways to cancel the file recognition directly? Thank you~~ Eric
