C++/Qt, OpenGL texture mapping - c++

Question

I'm attempting to render a texture that has been mapped to the graphics video memory. I have used qDebug to test that input of my image, indeed it possesses a 512x512 image which is a power of 2. Yet still when I attempt to render, instead of a texture the result is merely a quad which is white.
To note: GLuint m_textureIdents[1]; is correctly defined in GLWidget.h
#include "GLWidget.h"
GLWidget::GLWidget(QWidget *parent) : QGLWidget(parent)
{
setMouseTracking(true);
m_sceneIndex = SinQuest::SplashScreen;
}
void GLWidget::setApplicationPath(QString strAppPath)
{
m_strAppPath = strAppPath;
}
#include <QDebug>
void GLWidget::loadResources(void)
{
m_imageHandler.addImage(QString(m_strAppPath).append(QDir().toNativeSeparators("\\resources\\images\\")).append("splash_logo.png"), "splash-logo");
QImage glImageData = QGLWidget::convertToGLFormat(*m_imageHandler.getImage("splash-logo"));
qDebug() << glImageData.width() << ":" << glImageData.height();
m_textureIdents[0] = 0;
glGenTextures(1, &m_textureIdents[0]);
glBindTexture(GL_TEXTURE_2D, m_textureIdents[0]);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, glImageData.width(), glImageData.height(), 0, GL_RGB, GL_UNSIGNED_BYTE, glImageData.bits());
