如何在OpenGL c++中使用imgui制作按钮

#include <GL/gl3w.h>
#include <GLFW/glfw3.h>
#include <imgui.h>
#include <imgui_impl_glfw.h>
#include <imgui_impl_opengl3.h>

// 初始化GLFW
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

// 创建窗口
GLFWwindow* window = glfwCreateWindow(800, 600, "ImGui Button Example", nullptr, nullptr);
glfwMakeContextCurrent(window);
gl3wInit();

// 初始化ImGui
IMGUI_CHECKVERSION();
ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO();
(void)io;

ImGui_ImplGlfw_InitForOpenGL(window, true);
ImGui_ImplOpenGL3_Init("#version 330 core");

while (!glfwWindowShouldClose(window))
{
    glfwPollEvents();

    ImGui_ImplOpenGL3_NewFrame();
    ImGui_ImplGlfw_NewFrame();
    ImGui::NewFrame();

    // 创建一个按钮
    if (ImGui::Button("Click Me"))
    {
        // 按钮被点击时的逻辑处理
        // 可以在这里添加你想要执行的代码
    }

    ImGui::Render();
    int display_w, display_h;
    glfwGetFramebufferSize(window, &display_w, &display_h);
    glViewport(0, 0, display_w, display_h);
    glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
    glClear(GL_COLOR_BUFFER_BIT);

    ImGui_ImplOpenGL3_RenderDrawData(ImGui::GetDrawData());

    glfwSwapBuffers(window);
}

ImGui_ImplOpenGL3_Shutdown();
ImGui_ImplGlfw_Shutdown();
ImGui::DestroyContext();

glfwDestroyWindow(window);
glfwTerminate();
