Re: [Lazarus] OSX 64 bit Cocoa + Catalina Installer
I have to search my backup drives for some of this code, but I believe I also added a few extra classes to simplify some of the weirdness of Apple's classes. For example I greatly simplified the steps needed to work with CGContext and CGBitmapContextCreate such that it was completely transparent. A TCGBitmap class was defined (not in the framework, but wrapping CGBitmapContextCreate), and it would be compatible with TCGContext, but adding methods for loading, saving, blitting ect. Also some types have been simplified, NSString becomes regular pascal string, NSRect/CGRect becomes TRectF, and so on. Obviously defining all these types is definitely a lot of work, but to reiterate it does aid in type safety, object management, and discovery (how to combine the use the Framework objects with each other). One approach to tackling all this work, if anyone decides it's beneficial, might be to add it in gradually for what is needed, which is how I am using it right now. -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Re: [Lazarus] OSX 64 bit Cocoa + Catalina Installer
Dimitry, What I've done is created a reference counted class hierarchy to match part of the Cocoa framework. It's only partially done, but it allows Pascal code to be written to simplify interaction with native OSX frameworks and APIs like AppKit in the following ways: Using NSWindow class as an example: https://developer.apple.com/documentation/appkit/nswindow * TNSWindow mirrors NSWindow and uses an automatic reference counting scheme to automatically release objects when they are are no longer needed. * All methods and properties of NSWindow are provided by TNSWindow and there is no need to pass native objects as handles to functions. It's implicit in Self and the underlying handle is manged by TNSWindow -> TNSResponder -> TNSObject -> and ultimately TFrameworkObject. * It uses an object oriented hierarchy the same as the Apple frameworks, only translated to Pascal objects. That is you can pass a derived class to methods of other object methods which may expect any less specific class. * Other classes such as CGContext (TCGContext -> TFrameworkObject) are provided as well as other Apple frameworks classes, all translated to Pascal classes with all the same benefits as outlined above. My implementation isn't complete, which is to say I haven't wrapped every single Apple framework class in the manner described above. For the extremely limited amount of translations I did complete, I saw a big benefit in my own personal projects on OSX. Most notably the way of organizing code I outlined above allowed me to much more easily understand how to use Apple's frameworks, reduce errors with type safety and automatic object lifetime management, as well as aid in the discovery when combining Apple framework object to accomplish programming tasks. I expect if this were integrated into the Cocoa widgetset it would make development a bit easier. Certainly there is a lot of work involved in defining every Apple framework object in this way, but it provides a certain level of organization and usability that I at least feel makes a big difference when working with native Apple APIs. -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Re: [Lazarus] OSX 64 bit Cocoa + Catalina Installer
Note to all, the install source I posted comes from a random clone of svn trunk fpc and trunk lazarus put together from whatever was in the svn repository on Saturday. As such it might contain any number of potential bugs. That said, the reason trunk sources should be used is that the Cocoa widgetset is still in a beta state. Personally I've implemented some OSX core classes in a manner that is much more elegant manner that what's currently used in the Cocoa widgetset and if time permits I may propose some of my changes that could push Cocoa forward in a positive direction. I feel that many of the problems everyone might be experiencing is tied to the specific implementation state we currently have. This is not meant as a dig on the Cocoa LCL widgetset developers, obviously its difficult and tedious work trying to create a 100% compatible and bug free implementation and you work is very much appreciated so please keep it up! I know well get it working. On a side note, if anyone reading this message has done some work on committing widgetset code to Lazarus, either with the Gtk3 or Cocoa libraries, and would like to coordinate some of my improvements we can take this discussion to private emails or perhaps freenode irc and we can hash out merging my work. -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

I'll test the debugger options later.
