QtOpenglWidget black quad texture

[Gmadges]

Hi there,
I am trying to render a basic textured quad in openGL. I've tried this with both glew and QopenglFunctions and get the same outcome, a black quad.

Here is a my code below.
The shaders compile fine.
I receive the texCoords correctly within the shader.

Any thoughts would be helpful.

GLfloat tmpdata[] = {
//pos				//colour			//texCoord
-0.5f, -0.5f, 1.0f, 1.0f, 1.0f, 0.0f, 1.0f,  // Bottom-left
0.5f, -0.5f, 0.0f, 0.0f, 1.0f, 1.0f, 1.0f, // Bottom-right
-0.5f, 0.5f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, // Top-left
0.5f, 0.5f, 0.0f, 1.0f, 0.0f, 1.0f, 0.0f // Top-right

};

GLRenderer::GLRenderer(QWidget *parent)
:
QOpenGLWidget(parent),
m_ShaderProgram(0)
{
m_vertShader = "#version 150 core\n"
	"in vec2 position;"
	"in vec3 color;"
	"in vec2 texcoord;"
	"out vec3 Color;"
	"out vec2 Texcoord;"
	"void main() {"
	"   Color = color;"
	"   Texcoord = texcoord;"
	"   gl_Position = vec4(position, 0.0, 1.0);"
	"}";

 m_fragShader = "#version 150 core\n"
	"in vec3 Color;"
	"in vec2 Texcoord;"
	"out vec4 outColor;"
	"uniform sampler2D tex;"
	"void main() {"
	//"   outColor = texture(tex, Texcoord) * vec4(Color, 1.0);"
	//"   outColor = vec4(Color, 1.0f);"
	//"   outColor = vec4(Texcoord, 0.0f, 1.0f);"
	"   outColor = texture(tex, Texcoord);"
	"}";
