View Full Version : glfwSetWindowTitle not working for me?

Hi, I took some advice given to me on my previous topic and began learning GLFW (seems nice enough so far), but I have hit a snag. glfwSetWindowTitle isn't working for me at all. The window I've created keeps the default name, regardless, though behaving properly otherwise.

Tutorial program that works: GLFW:Tutorials:Basics (An Example) (http://content.gpwiki.org/index.php/GLFW:Tutorials:Basics#An_Example)

My test source, so far:

#include<GL/glfw.h>
#include<stdlib.h>
#include<stdio.h>
void init(int width,int height,const char* title){
glfwInit();
glfwOpenWindowHint(GLFW_WINDOW_NO_RESIZE,GL_TRUE);
if (glfwOpenWindow(width,height, 5, 6, 5, 0, 0, 0, GLFW_WINDOW) != GL_TRUE)
glfwTerminate();
glfwSetWindowTitle(title);
}
int main(){
while(0==0){
init(640,480,"title");
getchar();
glfwTerminate();
}
}


Obviously, I haven't gotten around to glfw's keyboard input stuff yet, but this is just a window test anyway. Hopefully, someone can point out what is probably obviously-wrong with my work so far. @_@;

What's wrong is that you keep initializing GLFW in your loop. Your `init` call should be outside of the loop.

Also, the traditional method for creating an infinite loop is `while(true)`.

Thank you for the while-loop advice, and also for pointing out my little goof-up, I could have sworn it was outside of it... @_@

Well, we all make silly little mistakes sometimes, right? ^_^ Thanks a ton!

ReEDIT: Thanks, while(1) saves a bit of time typing, lol... Anyway, the following code is just as ineffective:

#include<GL/glfw.h>
#include<stdlib.h>
#include<stdio.h>
void init(int width,int height,const char* title){
glfwInit();
glfwOpenWindowHint(GLFW_WINDOW_NO_RESIZE,GL_TRUE);
if (glfwOpenWindow(width,height, 5, 6, 5, 0, 0, 0, GLFW_WINDOW) != GL_TRUE)
glfwTerminate();
glfwSetWindowTitle(title);
}
int main(){
init(640,480,"title");
while(1){
getchar();
glfwTerminate();
}
}

I have no idea what's up, but it just isn't renaming the window. @_@;

EDIT: SUCCESS! I added glfwPollEvents so I could test key input while waiting, and that fixed everything, somehow ^_^
