使用NSBorderlessWindowMask时，视图周围有灰色边框 [英] Grey border around view when using NSBorderlessWindowMask

问题描述

我遇到的问题与这个问题完全相同：

I'm having the exact same problem as in this question:

使用NSBorderlessWindowMask时的灰色边框

但是，删除窗口阴影的接受答案至少在狮子会上。

However, the accepted answer (as in the comments) of removing the window shadow doesn't seem to work, at least on Lion.

我已经将 code>，并以这种方式创建了一个无边框窗口：

I've subclassed NSWindow, and created a borderless window in this manner:

-(id)initWithContentRect:(NSRect)contentRect styleMask:(NSUInteger)aStyle backing:(NSBackingStoreType)bufferingType defer:(BOOL)flag {

    self = [super initWithContentRect:contentRect 
                            styleMask:(NSBorderlessWindowMask | NSResizableWindowMask)
                              backing:bufferingType 
                                defer:flag];

    [self setMovableByWindowBackground:YES];
    [self setOpaque:NO];
    [self setBackgroundColor:[NSColor clearColor]];
    [self setHasShadow:YES];

    [self setLevel:NSMainMenuWindowLevel];
    return self;
}

请注意，此应用程式只会在Lion上执行$ c> NSResizableWindowMask 不会改变外观）。我尝试禁用阴影，并为我的窗口切换许多设置，但我似乎无法删除此灰色边框：

Please note that this app will only be run on Lion (so NSResizableWindowMask doesn't change the appearance). I tried disabling the shadow, and toggling numerous settings for my window but I can't seem to remove this grey border:

我的代码中没有任何地方可以添加边框。我只需在窗口中的Interface Builder中添加一个 NSSplitView 。在运行时，我将彩色视图作为子视图添加到拆分视图的左窗格，完全填充左拆分视图的边界。

Nowhere in my code do I add a border. I simply have a NSSplitView added in Interface Builder in a window. During runtime I add the colored view as a subview to the left pane of the split view, completely filling the bounds of the left split view.

编辑：即使使用简单的 NSView ，甚至不能拆分视图。

This happens even using a simple NSView, not even a split view.

TL; DR ：为什么我的 NSView 周围有灰色边框？

TL;DR: Why does my NSView have a grey border around it?

推荐答案

确定了。删除阴影只需将它添加到您的 NSWindow 子类：

ok got it. to remove the shadow simply add this to your NSWindow subclass:

- (BOOL)hasShadow {
    return NO;
}

并移除边框，您需要知道此边框来自视图 - 不是窗口（就像你在编辑中说的那样）。因此，您必须使用此代码禁用视图的边框：

and to remove the border you need to know that this border is coming from the view - not the window (just like you said it in your edit). So you have to disable the border for the view with this code:

[myview setBorderType:NSNoBorder];
