[Obj-C++] 19 NSWindowの重複 : 正攻法の解決手段 / 仕上げ

[M1 Mac, Big Sur 11.6.5, clang 13.0.0, no Xcode]

AppDelegateにDrag & Dropに関連する操作を集約させて仕上げました。異常終了についても修正しました。

NSWindow初期化, NSTextField・NSView作成をAppDelegateに移管しています。

初学者にはかなりきつい内容でしたが、それなりに基礎固めできたように思います。Objective-C++を学び始めて2週間ですから進度としてはまずまずです。

#import "AppDelegate.h"
#import "DragAndDropView.h"
#import "ConvertorWindow.h"

@interface AppDelegate() <DragAndDropViewDelegate,

@property (nonatomic, assign) ConvertorWindow* windowInit;
@property (nonatomic, assign) NSTextField* textBox1;
@end

@implementation AppDelegate

    // NSWindow
    _windowInit = [[ConvertorWindow alloc] init];
    [_windowInit autorelease];
    [_windowInit makeKeyAndOrderFront:NSApp];
	[_windowInit setTitle:@"Xlsx Convertor"];

    // NSTextField
    _textBox1 = [[[NSTextField alloc] initWithFrame:NSMakeRect(50, 265-25-10, 220, 25)] autorelease];
	[_textBox1 setStringValue:@""];
	[_textBox1 setEditable:YES];
	[[_textBox1 window] makeFirstResponder:nil];
	[[_textBox1 currentEditor] moveToEndOfLine:nil];
    [[_windowInit contentView] addSubview:_textBox1];

    // NSView
	_view_dad = [[DragAndDropView alloc] initWithFrame:NSMakeRect(0, 0, 360, 265)];
	[_view_dad setWantsLayer:NO];
	_view_dad.layer.backgroundColor = [[NSColor orangeColor] CGColor];
    [[_windowInit contentView] addSubview:_view_dad];

    NSLog(@"%s","applicationWillFinishLaunching");
