GLFW adapter not drawing Properly

[VigneshGunasekaran96]

I am using the glfw-opengl4 demo to draw. I don't get any compile errors. But the windows are not drawing properly. Here is the Image

Code:

ImGuiLayer.h

#pragma once

#define NK_GLFW_GL4_IMPLEMENTATION
#define NK_UINT_DRAW_INDEX
#define NK_INCLUDE_FIXED_TYPES
#define NK_INCLUDE_STANDARD_IO
#define NK_INCLUDE_STANDARD_VARARGS

#include "Atlas/Layer.h"

struct nk_context;
struct nk_image;

namespace atlas
{
	class CImGuiLayer : public CLayer
	{
	private:
	        ...
		nk_context* ctx;
		struct nk_image* img;
	};
}

ImGuiLayer.cpp

		struct nk_font_atlas* atlas;
		nk_glfw3_font_stash_begin( &atlas );

		};
		char pixels[ tex_width * tex_height * 4 ];
		memset( pixels, 128, sizeof( pixels ) );
		tex_index = nk_glfw3_create_texture( pixels, tex_width, tex_height );
