Hi,
I'm using GLFW3 to setup a gl context and window events.
I believe when the canvas resizes (i.e. to go fullscreen or otherwise due
to the webpage window being resized), then the callback registered using
glfwSetWindowSizeCallback should get called.
I've tested this, but I don't seem to be seeing the callback being called.
I've attached code which will reproduce the issue and have compiled with
these flags: -std=c++11 -s USE_GLFW=3
using the following code:
#include<stdio.h>
#include<stdlib.h>
#include<emscripten/emscripten.h>
#define GLFW_INCLUDE_ES2
#include<GLFW/glfw3.h>
int windowWidth;
int windowHeight;
void window_size_callback(GLFWwindow* window, int width, int height)
{
printf("window_size_callback received width: %i, height: %i\n", width,
height);
}
void do_frame(){
}
int main(int argc, char **argv) {
GLFWwindow *window;
if (glfwInit()!=GL_TRUE) {
printf("glfwInit() failed\n");
glfwTerminate();
} else {
printf("glfwInit() success\n");
window = glfwCreateWindow(640, 480, "GLFW test", NULL, NULL);
if (!window){
printf("glfwCreateWindow() failed\n");
glfwTerminate();
} else {
printf("glfwCreateWindow() success\n");
glfwMakeContextCurrent(window);
glfwGetFramebufferSize(window, &windowWidth, &windowHeight);
glfwSetWindowSizeCallback(window, window_size_callback);
emscripten_set_main_loop(do_frame, 0, 1);
glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
}
}
glfwTerminate();
return EXIT_SUCCESS;
}
Any ideas why this might be, or workarounds I could use? Would be much
appreciated! Cheers!
