窗口浮在桌面上，但在其他一切 [英] window floating above desktop but behind everything else

问题描述

我有我的应用程序的所有设置，以做我想要它做的。
但有一件事我不能弄清楚如何做。
如何让窗口出现在桌面上。
在您的桌面上，它将在桌面上，但在其他一切。

I have my app all setup to do what i want it to do. But there is one thing i can't figure out how to do. How do i make the window appear on the desktop. As in its like on your desktop and it will be above the desktop, but behind everything else.

我没有想出如何做到这一点。 ..
任何想法

I haven't figured out how to do this... Any ideas??

推荐答案

找到您要找的键是：kCGDesktopWindowLevelKey，
找了一个例子，发现

Found the key you are looking for is: kCGDesktopWindowLevelKey, had a look for example and found Re: NSWindow order back and stay, dammit! -Applle mailing list

我想最好是做CGWindowLevelForKey（kCGDesktopWindowLevelKey）+1，
以确保它在常规桌面之上，但低于一切。

"I think it would be better to do CGWindowLevelForKey(kCGDesktopWindowLevelKey)+1, to make sure it's above the regular desktop, but below everything else.."

这似乎可以工作。

CGWindowLevel  desktopWinLevel =  CGWindowLevelForKey(kCGDesktopWindowLevelKey)+1;
[desktopWinLevel setLevel:winLevel];
