OpenGL GLUT Fullscreen / Windowed Switching

Hi peeps

Having a little trouble here

I want to switch between windowed and fullscreen modes using GLUT using key 'f' or key 'F'.

I found a glutFullScreen() method which works fine, but when it switches back to windowed (which takes 4 times to press f) makes the size of the window fine but it comes without its title bar etc! :(

so erm
ive tried lots of different glut methods
and i cant seem to work out whats goin on
ive searched mr.google and cant find a way out

what is glutentergamemode glutleavegamemode all about, is it better, nicer, newer and does it even do this?! :S

any ideas?....

heres the code for what i got so far....

Code:

---

    case 70:
    case 102: /* Fullscreen mode (Additional) : f/F */
      fullscreen = !fullscreen;
      if (fullscreen)
      {
        glutFullScreen();                /* Go to full screen */
      }
      else
      {
        glutReshapeWindow(800, 600);        /* Restore us */
        glutPositionWindow(0,0);
      }
      break;

---

but i want to set it to the width height of the window before fullscreen, but it doesnt like that in glutReshapeWindow()

It could be that the program is still operating in fullscreen mode, but you are making the size of the window less than your resolution, so it is working similiar to a WS_POPUP window. You probably have to do a command to kick it out of fullscreen mode after the window is resized.

full screen mode?
sounds logical but how do i get 'out' of full screen mode?
all i get is a window without the attributes iof the window like minimize maximize close and the title bar....

i changed the code so that pressing 'w' changes reolution between:#
640x480
800x600
1024x768
fullscreen (and back again of course)

Code:

---

    case 87:
    case 119: /* Window size (Additional) : w/W */
      if (width == 640)
      {
        width = 800;
        height = 600;
        glutReshapeWindow(width, height);
      }
      else if (width == 800)
      {
        width = 1024;
        height = 768;
        glutReshapeWindow(width, height);
      }
      else if (width == 1024)
      {
        glutFullScreen();
      }
      else
      {
        width = 640;
        height = 480;
        glutReshapeWindow(width, height);
      }
      break;

please please please help me, im a n00b, and i cant find the answer anywhere!

Not sure about the key press problem (maybe try using a different set of keys like '+' and '-').

As far as the title bar disappearing, try setting the window position further in:

Code:

---

glutPositionWindow(100,100);

---

That seems to work for me.

key press problem i solved by using the same keypress for all windows...

unfortunately the window position hasnt helped

thanks anyway

i must be making a fundamental mistake (wouldnt put it past myself :p )
