我想将 Dear ImGui 元素渲染到两个不同的 glfw 窗口。
我从这里有这个示例代码:
#include <GLFW/glfw3.h>
int main(void)
{
GLFWwindow* window1;
GLFWwindow* window2;
/* Initialize the library */
if (!glfwInit())
return -1;
/* Create a windowed mode window and its OpenGL context */
window1 = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
if (!window1)
{
glfwTerminate();
return -1;
}
/* Create a second windowed mode window and its OpenGL context */
window2 = glfwCreateWindow(640, 480, "World Hello", NULL, NULL);
if (!window2)
{
glfwTerminate();
return -1;
}
/* Loop until the user closes the window */
while (!glfwWindowShouldClose(window1) && !glfwWindowShouldClose(window2))
{
/* Make the window's context current */
glfwMakeContextCurrent(window1);
/* Render here */
glClear(GL_COLOR_BUFFER_BIT);
/* Swap front and back buffers */
glfwSwapBuffers(window1);
/* Make the second window's context current */
glfwMakeContextCurrent(window2);
/* Render here */
glClear(GL_COLOR_BUFFER_BIT);
/* Swap front and back buffers */
glfwSwapBuffers(window2);
/* Poll for and process events */
glfwPollEvents();
}
glfwTerminate();
return 0;
}
如果设置了 ImGui,我如何转换此代码以便我可以在两个窗口中呈现(不同的)ImGui。
