使用Cocoa在辅助显示器上显示os x窗口全屏 [英] Display os x window full screen on secondary monitor using Cocoa

问题描述

我正在开发一个Cocoa Mac应用程序，我需要在辅助显示器上全屏显示窗口/视图。我知道如何创建一个窗口，可以拖动到辅助监视器，但我想要编程创建窗口，并使其在外部监视器上的全屏。感谢您的帮助。

解决方案

首先，通过迭代[NSScreen屏幕]确定要使用的屏幕。 >

创建一个全屏窗口：

  NSScreen * screen = / * [NSScreen screen] * / 
 NSRect screenRect = [screen frame]; 
 NSWindow * window = [[NSWindow alloc] initWithContentRect：screenRect 
 styleMask：NSBorderlessWindowMask 
 backing：NSBackingStoreBuffered 
 defer：NO 
 screen：screen]; 
 [window setLevel：CGShieldingWindowLevel（）]; 
  

您也可以同时使用google CGDisplayCapture（）。

I'm working on a Cocoa Mac app where I need to display a window/view on a secondary monitor, full-screen. I know how to create a window that could be dragged onto the secondary monitor, but I was wanting to programatically create the window and make it full screen on the external monitor. Thanks for the help.

解决方案

First, determine which screen you want to use by iterating over [NSScreen screens].

Create a full screen window with:

NSScreen *screen = /* from [NSScreen screens] */
NSRect screenRect = [screen frame];
NSWindow *window = [[NSWindow alloc] initWithContentRect:screenRect
    styleMask:NSBorderlessWindowMask
    backing:NSBackingStoreBuffered
    defer:NO
    screen:screen];
[window setLevel: CGShieldingWindowLevel()];

You might want to google CGDisplayCapture() as well.
