How to use NSWindowController on MacOS

Dmitriano

I have a QML app where I need to set ApplicationWindow aspect ratio somehow.

My idea is that I probably use the following native code on MacOS:

#import <Cocoa/Cocoa.h>

NS_ASSUME_NONNULL_BEGIN

@interface MyWindowController : NSWindowController

@end

NS_ASSUME_NONNULL_END

#import "MyWindowController.h"

@interface MyWindowController ()
@end

@implementation MyWindowController

- (void)windowDidLoad {
    [super windowDidLoad];
    // set the aspect ratio here
    [self.window setAspectRatio:NSMakeSize(320.0, 640.0)];
}

@end

but it is not clear how to assign my class to the Window Controller. And it is not clear is it created internally in QT or not.

Hi,

Unless I am mistaken, for what you want to do you do not need a NSWindowController.

Retrieve the NSWindow from your QWindow and apply the change you implemented.
