c++ - glfw openGL c++ 窗口背景和标题

Question

这是我正在查看的关于 opengl 3+ 的一系列教程的源代码。

//#include <stdio.h>
//#include <stdlib.h>

#include <GL/glew.h>
#include <GL/glfw.h>
#include <glm/glm.hpp>
using namespace glm;

#include <iostream>
using namespace std;



int main()
{

    if( !glfwInit() )
    {
        fprintf( stderr, "Failed to initialize GLFW\n" );
        return -1;
    }

    glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4); // 4x antialiasing
    glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); // We want OpenGL 3.3
    glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 2);
    glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //We don't want the old OpenGL

    // Open a window and create its OpenGL context
    if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
    {
        fprintf( stderr, "Failed to open GLFW window\n" );
        glfwTerminate();
        return -1;
    }
    else
    {
        glfwSetWindowTitle( "Tutorial 01" );
    }

    // Initialize GLEW
    glewExperimental=true; // Needed in core profile
    if (glewInit() != GLEW_OK) {
        fprintf(stderr, "Failed to initialize GLEW\n");
        return -1;
    }



    glfwEnable( GLFW_STICKY_KEYS );

    do{
        // Draw nothing, see you in tutorial 2 !

        // Swap buffers
        glfwSwapBuffers();

    } // Check if the ESC key was pressed or the window was closed
    while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
    glfwGetWindowParam( GLFW_OPENED ) );

    return 0;
}

一切都很好，除了当窗口初始化时它有一个白色的背景颜色和标题“GLFW WINDOW”，但是在 1-2 秒后标题变成了 Tutorial 01，因为它本来应该放在第一位，并且背景变成黑色，本应如此。

在我几年前做过的关于 opengl (2.x) 过剩的研究中，我没有遇到过这样的问题，有人能解释一下这里出了什么问题吗？

我在 ATI FirePro V5700 上得到了相同的行为(甚至在 IDE 之外运行发布 exe)。如果你真的被它困扰，download the GLFW source并更改carbon_window.c的第764行、win32_window.c的第1210行和x11_window.c的第962行。

.\lib\carbon\carbon_window.c

(void)SetWindowTitleWithCFString( _glfwWin.window, CFSTR( "GLFW Window" ) );

.\lib\win32\win32_window.c

_glfwWin.window = CreateWindowEx( _glfwWin.dwExStyle,    // Extended style
                                  _GLFW_WNDCLASSNAME,    // Class name
                                  "GLFW Window",         // Window title
                                  _glfwWin.dwStyle,      // Defined window style
                                  wa.left, wa.top,       // Window position
                                  fullWidth,             // Decorated window width
                                  fullHeight,            // Decorated window height
                                  NULL,                  // No parent window
                                  NULL,                  // No menu
                                  _glfwLibrary.instance, // Instance
                                  NULL );                // Nothing to WM_CREATE

.\lib\x11\x11_window.c

_glfwPlatformSetWindowTitle( "GLFW Window" );
