在OS X中以编程方式获取屏幕分辨率 [英] Get screen resolution programmatically in OS X

问题描述

我想在Mac上以原生分辨率启动全屏3D C ++应用程序。
如何检索原生屏幕分辨率？

I'd like to launch a fullscreen 3D C++ application in native resolution on mac. How can I retrieve the native screen resolution ?

推荐答案

如果你不想使用Objective C，get您希望在其上显示的显示ID（使用例如 CGMainDisplayID ），然后使用 CGDisplayPixelsWide 和 CGDisplayPixelsHigh 来获取屏幕宽度和高度，以像素为单位。请参阅获取有关显示的信息了解如何获取其他显示信息。

If you don't wish to use Objective C, get the display ID that you wish to display on (using e.g. CGMainDisplayID), then use CGDisplayPixelsWide and CGDisplayPixelsHigh to get the screen width and height, in pixels. See "Getting Information About Displays" for how to get other display information.

如果你愿意使用一点Objective-C，只需使用 [[NSScreen mainScreen] frame] 。

If you're willing to use a bit of Objective-C, simply use [[NSScreen mainScreen] frame].

请注意，全屏显示还有其他问题，即确保其他应用程序不会这样做。阅读绘制全屏 Apple's OpenGL Programming Guide for more。

Note that there are other concerns with full screen display, namely ensuring other applications don't do the same. Read "Drawing to the Full Screen" in Apple's OpenGL Programming Guide for more.
