Syncing nuklear form's position with GLFW's window position ?

[malvinn13]

Hey, i want to make a window that is borderless(From GLFW) and i want to make it movable.
It looks like this:

I want to make it movable so i tried to override the nuklear.h code but didn't worked. Can you help me with this ?
The Nuklear Form' width and height are the same as GLFW's.
EDIT: i want to handle the X button, the window is closing but instantly reopens when i press the button, dont rlly know how to work with it, can you help me with this too ?

Hey @malvinro,
if I understand you correctly you want to span a nuklear window completely over the OS window and use nuklears window header as os window header.

What I would propose is to use the OS window header and a headerless nuklear window. The problem with using nuklear for OS window movement is that the OS renderer is always faster than nuklear in drawing (The kernel has more information). So while possible to do what you want it causes glitches.

So the best cause of action would be to use the OS window decoration for maximum smoothness for movement.

EDIT: i want to handle the X button, the window is closing but instantly reopens when i press the button, dont rlly know how to work with it, can you help me with this too ?

Nuklear does not close the window. It only marks it as closed to be polled if closed. So you have to detect in your code that it was closed and not call the window anymore. This can be easily implemented by having a boolean check:

static int win_unresolved_visible = true;
if (win_unresolved_visible) {
    if (nk_begin(..., "unresolved",....)) {
        /* ... */
    }
    nk_end(...);
}
win_unresolved_visible = nk_window_is_closed(ctx, "unresolved") ? false : true;

or if you want to close the application something like this:

if (nk_begin(..., "unresolved",....)) {
    /* ... */
}
nk_end(...);

if (nk_window_is_closed(ctx, "unresolved")) {
    exit(1);
}

EDIT:
Also if you mean how to span nuklears window over the OS window do this:

if (nk_begin(..., "unresolved", ....)) {
    nk_window_set_size(ctx, "unresolved", nk_vec2(glfw.width, glfw.height));
}
nk_end(...);

Thw win_unresolved_visible variable is never turning false, that's my code:

The OS header looks like shit, i want to overwrite your code, and instead of changing the nuklear form's position i would change the os window position, that should not glitch. It's glitching now bc NK_MOVABLE move the nuklear window, if the calculation of the new position would write the OS Window Position than it should do the work.

This is happening, can't get it closed.

Oops you are correct it should be:

if (nk_window_is_hidden(ctx, "unresolved"))
    exit(1);

The 'x' only hides the specified window. While nk_window_close actually closes the window which can be checked with nk_window_is_closed.

[malvinn13]

Yeah, now it's working.
I m trying to move the window myself but i can't find the the mouse position on the header, could you help me with this ?
I found the Mouse X, Y, the window X,Y, but when i need to move it i need to set the window position to the Mouse X,Y Position - some value for which i cant find a formula for.

EDIT:
I've changed the taskbar icon but the icon from here wont change, do you have any idea about how i could change it ?

[malvinn13]

Found out how to make it movable, if someone wants to do it too simply create a variable (mine's a point named distFromWinToMouse) then insert this into your while function.

if ((GetKeyState(VK_LBUTTON) & 0x100) != 0) {
	POINT p;
	int curX, curY;
	if (GetCursorPos(&p)){
		glfwGetWindowPos(win, &curX, &curY);
		if (iMPressed && p.x < curX + WINDOW_WIDTH + 500 && p.x > curX - 500 && p.y < curY + ctx->active->layout->header_height + 500 && p.y > curY - 500)
		 glfwSetWindowPos(win, p.x - distFromWinToMouse.x, p.y - distFromWinToMouse.y);
		else {
		if (p.x < curX + WINDOW_WIDTH && p.x > curX &&
		p.y < curY + ctx->active->layout->header_height && p.y > curY) {
		distFromWinToMouse.x = p.x - curX;
		distFromWinToMouse.y = p.y - curY;
		glfwSetWindowPos(win, p.x - distFromWinToMouse.x, p.y - distFromWinToMouse.y);
		iMPressed = true;
		}		
	}		
}
}

Now i just want to change the icon from the taskbar, when i click right my program.

I think I am a little lost at this point. Can this issue be marked fixed?

[malvinn13]

Nah, if you could help me, how i can change this icon:

And how can i set the icon to the app to be like an embed icon. If i run the app from a folder it wont show the icon :(

The icon question is out of the Nuklear scope. But I would start e.g. with https://msdn.microsoft.com/en-us/library/windows/desktop/ms648051(v=vs.85).aspx or similar (just google it - this was right the second match I got).
