[Development] Blacklines only in OpenGL in a QGLView

[niallcwhelan at eircom.net]

Hi,

  I'm using QGLView and glColor3f to set a line colour to any colour, but it only renders black lines.

For example:

void CubeView::plotLine( QVector3D start, QVector3D end )
{
    glColor3f(1.0f,1.0f,1.0f);   // Set my lines colour...
    glLineWidth(3.0);
    glEnable(GL_LINE_SMOOTH);

    glBegin(GL_LINES);
    glVertex3f(start.x(), start.y(), start.z());
    glVertex3f(end.x(), end.y(), end.z());
    glEnd();

    glFlush();
}


Regardless of values is glColor3f, black is the only line colour drawn.

Suggestions gratefully received.

Niall.
