从kCGWindowNumber获取NSWindow [英] Get NSWindow from kCGWindowNumber

问题描述

如何从k CGWindowNumber中获取NSWindow参考. 我尝试使用:

From kCGWindowNumber, how do I get NSWindow ref. I tried using:

[NSApp windowWithWindowNumber:windowNumber]

但是我总是得到一个空值. 我需要获取NSWindow来应用[window setlevel:NSFloatingWindowLevel]，我已经将all始终设置在给定窗口的顶部. 有人知道如何解决此问题或有其他替代解决方案吗?

but I always get a null value. I need to get the NSWindow to apply [window setlevel:NSFloatingWindowLevel], that I have set the always on top of a given window. Does anyone know how to solve this problem or has any alternative solution?

感谢您的回答，但这不是解决方案，我已经尝试过了，但是没有用，实际上我做了一个测试， 我尝试了以下代码:

Thanks for the answer, but this is not the solution, I had already tried but it does not work, actually I did a test , I tried the following code:

for (NSInteger i = 0; i <10000; i + +) {
NSWindow * wind;
wind = [NSApp windowWithWindowNumber: windowNumber];
NSLog (@ "\ n Window:% @", wind);
}

，但结果始终是Window: (null)

我有一个窗口列表，在哪里可以获取OwnerPid窗口的ecc数.. ecc ...，现在我需要将始终设置在某些窗口的顶部.

I have a list of window, where can i get OwnerPid Number of window ecc.. ecc... and now I need to set the always on top of some windows.

总是在顶部可以设置白色:[window setlevel:NSFloatingWindowLevel]，窗口是NSwindow对象，是真的吗?

The Always on top is possible set whit: [window setlevel:NSFloatingWindowLevel], window is a NSwindow object, it's real?

您有解决方案吗?或其他想法，解决我的问题?

Do you have a solution? or another idea , for my problem?

推荐答案

kCGWindowNumber是CFNumber/NSNumber，-windowWithWindowNumber:期望是NSInteger.在将整数传递给-windowWithWindowNumber:之前，您需要从窗口编号参考(使用-integerValue)中提取该整数.

kCGWindowNumber is a CFNumber/NSNumber, -windowWithWindowNumber: expects an NSInteger. You'll need to extract the integer out of the window number reference (with -integerValue) before passing it to -windowWithWindowNumber:.
