使无边框窗口具有更暗更大的阴影
当无边框窗口中的窗口变为活动状态时，如何创建更暗和更大的阴影？
我对 NSWindow 进行了子类化，我的窗口成为主窗口和关键窗口，但这没有帮助......阴影仍然很小。那么也许有人知道如何解决这个问题？我也尝试过使阴影无效，但这也没有帮助..
子类化 NSWindow：
- (id)initWithContentRect:(NSRect)contentRect
styleMask:(NSUInteger)windowStyle
backing:(NSBackingStoreType)bufferingType
defer:(BOOL)flag
{
self = [super initWithContentRect: contentRect
styleMask: NSBorderlessWindowMask
backing: NSBackingStoreBuffered
defer: NO];
if(self)
{
[self setHasShadow:YES];
[self setBackgroundColor:[NSColor clearColor]];
[self setOpaque:NO];
}
return self;
}
How to create darker and larger shadow when window becomes active in borderless window?
I subclassed NSWindow and my window becomes main window and key window but that's not helping.. shadow still small. So maybe someone knows how to fix this? I also tried invalidate shadow, but that didn't help too..

这与窗口的 styleMask 相关。如果将其设置为 NSTitledWindowMask 窗口将获得更大的阴影。
This is tied to the window's styleMask. If it is set to NSTitledWindowMask window will get a larger shadow.
如果这是我的问题，我可能会关闭无边框窗口的阴影属性关闭，然后处理来自
display我的NSWindow子类中的函数（确保调用[super display]以便各种内容和子类视图调用自己的绘制方法）。这是一个可能相关的问题以及供您考虑的答案。
If this were my problem, I'd probably turn the shadow property off for the borderless window and then handle the shadow drawing from a
displayfunction within myNSWindowsubclass (making sure to call[super display]so the various content & sub views get their own draw methods called).Here's a potentially related question with an answer for you to consider.
总的来说，我认为达尔马齐奥的观察是正确的，即无论出于何种原因，无边框窗户的阴影不太明显。也许可以向苹果归档雷达。
In general I think Dalmazio is correct in his observation that borderless windows have a less pronounced shadow for whatever reason. Maybe file radar with apple.
