如何在Objective-C + Cocoa中创建自定义无边框NSWindow？ [英] How do I create a custom borderless NSWindow in Objective-C + Cocoa?

问题描述

让我先说说这是我第一个真正的Cocoa应用程序。这是一个简单的应用程序，几乎显示我的网站在无边框的窗口。我现在创建一个无边框窗口的方式是使用以下：

Let me start off by saying that this is my first real Cocoa app. It's a simple app that pretty much displays my website in a borderless window. The way I'm currently creating a borderless window is using the following:

- (void) awakeFromNib {
    [window setStyleMask:NSBorderlessWindowMask];
    [window setAcceptsMouseMovedEvents:YES];
    [window setMovableByWindowBackground:YES];
    [window setLevel:NSNormalWindowLevel];
}

这样做的问题是，不会将鼠标悬停在加载的页面上的元素上，也不能在文本字段中输入。我知道我应该创建一个自定义窗口，并移动contentView到它，但我是太新的Objective-C来弄清楚如何。

The problem with this is that as a result, the WebView within the window does not pass mouse over events to elements on the loaded page, nor does it provide the ability to type in text fields. I know that I'm supposed to create a custom window instead and move the contentView into it but I'm too new to Objective-C to figure out how.

我还尝试声明所有这些没有运气：

I've also tried declaring all of these with no luck:

@implementation specikAppDelegate

@synthesize window;
@synthesize webView;

- (BOOL) canBecomeKeyWindow { return YES; }
- (BOOL) canBecomeMainWindow { return YES; }
- (BOOL) acceptsFirstResponder { return YES; }
- (BOOL) becomeFirstResponder { return YES; }
- (BOOL) resignFirstResponder { return YES; }

...

@end

另外，我想通过点击并拖动它在任何地方移动窗口，但这是一个想法。我已经在线搜索，找不到解决方案。

Additionally, I'd like to be able to move the window by clicking and dragging it anywhere but that's a side thought. I've searched extensively online, and cannot find a solution to this.

我的.h文件的内容（以防万一）：

Contents of my .h file (just in case):

@interface specikAppDelegate : NSObject <NSApplicationDelegate> {
    IBOutlet NSWindow *window;
    IBOutlet WebView *webView;
}

@property (assign) IBOutlet NSWindow *window;
@property (nonatomic, retain) IBOutlet WebView *webView;

- (IBAction)openAboutPanel:(id)sender;

@end

任何帮助将不胜感激，我是Objective-C和Cocoa的世界的新手，但我确实来自PHP开发背景。

Any help would be appreciated, and like I said, I'm super new to the world of Objective-C and Cocoa, but I do come from a PHP development background.

推荐答案

如此回答，没有标题或调整大小条的窗口（包括无边框窗口）不能成为关键窗口。

As explained in this answer, windows without title or resize bar (including borderless windows) cannot become key windows.

你是对的重写 -canBecomeKeyWindow ，但你错过了正确的地方。你不应该在你的应用程序委托。您需要创建一个 NSWindow 子类，然后重写该方法。

You were right about overriding -canBecomeKeyWindow, but you’ve missed the correct place. You shouldn’t do it in your application delegate. You need to create an NSWindow subclass and then override that method.
