ImGui button wit picture

To create an ImGui button with a picture in C++, follow these steps:

1. Include the necessary header files:

#include <imgui.h>
#include <imgui_impl_glfw.h>
#include <imgui_impl_opengl3.h>

1. Initialize the ImGui context and set up the GLFW and OpenGL3 implementations:

ImGui::CreateContext();
ImGui_ImplGlfw_InitForOpenGL(window, true);
ImGui_ImplOpenGL3_Init(glsl_version);

1. Load the image that you want to use as the button icon:

ImGuiIO& io = ImGui::GetIO();
ImTextureID buttonTextureID = io.Fonts->AddFontFromFileTTF("path/to/image.png", size);

1. Inside your rendering loop, begin a new ImGui frame:

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

1. Create the button using the image as its icon:

if (ImGui::ImageButton(buttonTextureID, ImVec2(width, height)))
{
    // Handle button click event
    // This code block will be executed when the button is clicked
}

Replace width and height with the desired dimensions of the button.

1. End the ImGui frame and render the ImGui UI:

ImGui::Render();
ImGui_ImplOpenGL3_RenderDrawData(ImGui::GetDrawData());

1. Clean up and shutdown ImGui at the end of your program:

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

Note: Make sure you have the necessary dependencies and libraries properly linked in your project.
