NSWindow has a method, setLevel:, that lets you control how the window is positioned compared to other windows. From my own experience, you might want to try feeding it kCGDesktopIconWindowLevel, and calling setHasShadow:NO to implement the look you want. To actually do the drawing you would put a custom NSView subclass in your window, and create the window without a frame (see NSBorderlessWindowMask) and transparent ([window setBackgroundColor:[NSColor clearColor]], [self setOpaque:NO];).
NSWindow有一个方法setLevel:,它允许您控制窗口与其他窗口相比的位置。根据我自己的经验,你可能想尝试喂它kCGDesktopIconWindowLevel,并调用setHasShadow:NO来实现你想要的外观。要实际绘制,你可以在窗口中放置一个自定义的NSView子类,并创建一个没有框架的窗口(参见NSBorderlessWindowMask)和透明([window setBackgroundColor:[NSColor clearColor]],[self setOpaque:NO];)。
