GLFW获取屏幕高度/宽度？ [英] GLFW get screen height/width?

问题描述

使用freeglut库，我决定使用GLFW作为我的下一个培训项目，因为我被告知GLUT只是为学习目的而设计，不应该被专业使用。我没有问题，链接lib到我的NetBeans项目，它编译很好，使用mingw32 4.6.2。

但是，我试图将窗口放在屏幕中央时遇到困难。
在freeglut下，我以前使用：

  glutInitWindowPosition（
（glutGet（GLUT_SCREEN_WIDTH）-RES_X） 2，
（glutGet（GLUT_SCREEN_HEIGHT）-RES_Y）/ 2 
）; 
  

我找不到任何会返回屏幕大小或宽度的glfw函数。

解决方案

glfwGetDesktopMode ，我想这是你想要的。

示例：

  GLFWvidmode return_struct; 
 
 glfwGetDesktopMode（& return_struct）; 
 
 int height = return_struct.Height; 
  

Playing around with OpenGL for a while, using the freeglut library, I decided that I will use GLFW for my next training project instead, since I was told that GLUT was only designed for learning purposes and should not be used professionally. I had no problems with linking the lib to my NetBeans project and it compiles just fine, using mingw32 4.6.2.

However, I am running into difficulties trying to position the window at the center of the screen. Under freeglut, I previously used:

glutInitWindowPosition ( 
                         (glutGet(GLUT_SCREEN_WIDTH)-RES_X)  / 2,
                         (glutGet(GLUT_SCREEN_HEIGHT)-RES_Y) / 2 
                       );

I can't find any glfw function that would return the screen size or width. Is such a function simply not implemented?

解决方案

How about glfwGetDesktopMode, I think this is what you want.

Example:

GLFWvidmode return_struct;

glfwGetDesktopMode( &return_struct );

int height = return_struct.Height;
