Yes, as the subject says.

I am currently working on an application using both GLFW and the (also very clean and portable) guisystem FLTK for my gameobject-editor.  
Unfortunately, closing the GLFW-window will kill everything, so I want to disable the windowborder and use some GLFW-gadgets instead,  
hooking it beside the GLFW displayarea by throwing around some coordinate variables. =)

Is this possible in the near future?  
Can someone help me with a workaround for this somehow until it is implemented?

(btw, if someone happens to have fltk experience, I KNOW there is openglsupport in it,  
but it uses glut… ;( )

If you wish to prevent the GLFW window from closing, set a window close callback. §3.2.4 of the reference manual.

ah… great!  
That will solve the main problem.

Will my feature request be relevant enough for inclusion in the future?  
I have a function declaration ready: glfwSetWindowBorder(bool state);  
Now just the function needs an implementation… =P

Anyway, looking forward to any glfw updates!  
thanks.

If you make an application without window borders, your users will hate you. Why would you want that?

Heh, well, I am the only user that is going to use it. =)=)  
It’s for my own gameframework. =)

But… it will have window borders, but not system-borders.  
I will make my own borders using fltk to integrate it into the look of my application gui.

Oh, and also, would it be possible to make glfw to not show the application in the taskbar?  
I just want one button in the taskbar… I’m trying to figure out the same thing for fltk.

It’s possible that GLFW 3.0 will support borderless windows, in order to accomodate splash screens, etc., as other people have been requesting such a feature.

I am interested in this feature. It might be useful to create something similar to xmms / winamp with custom buttons to close the window.

A 2D API like Quartz, Cairo or WPF would probably be a better fit that OpenGL for such an application. Nevertheless, yes, it would be possible.

Thanks, but I am interested in APIs/frameworks that are cross-platform.

Hi all !

For those wanting to remove window border, it’s quite an easy task under win32 ( yeah i needed that for a VJ thing i’m trying to make )

So here’s a little nifty function :

void glfwSetBorder(HWND window, int on)  
{  
RECT rect;  
DWORD style;

```
if\(window == NULL\)
	window = FindWindow\( &quot;GLFW&quot;, NULL\);

```

style = GetWindowLong(window, GWL\_STYLE);

if (on)  
{  
if (!GetWindowRect(window, &rect)) return;  
//if (!GetClientRect(window, &rect)) return;

```
style &amp;= ~WS\_OVERLAPPEDWINDOW;
style |= WS\_POPUP;
   AdjustWindowRect \(&amp;rect, style, TRUE\);
// &amp; ~WS\_CAPTION
   SetWindowLong\(window, GWL\_STYLE, style \);
 \}

```

else  
{  
if (!GetWindowRect(window, &rect)) return;

```
   style |= WS\_CAPTION;	
style |= WS\_OVERLAPPEDWINDOW;
style &amp;= ~WS\_POPUP;

   AdjustWindowRect \(&amp;rect, style, TRUE\);

   SetWindowLong\(window, GWL\_STYLE, style\);
 \}

SetWindowPos\(window, HWND\_TOPMOST,
            rect.left, rect.top,
            rect.right - rect.left, rect.bottom - rect.top,
            SWP\_NOMOVE | SWP\_FRAMECHANGED\);

```

}

Simply call : glfwSetBorder( NULL, 1); ( 0 to re-enabled the borders )

Hope that helps !

Oops, forgot to say that you need to put:

#include \<windows.h\>

somewhere in your code, of course ! 🙂

In order to get the sample code to build I had to change Findwindow call by  
adding a typecast. My guess this is not working:

if(window == NULL)  
window = FindWindow( (LPCWSTR)“GLFW”, NULL); //JL:: added (lpwstr) I  
think its wrong)

any ideas?
