I found the problem, window init in other thread, so it can not catch the resource.

And I test like this. Do not use loadFromImage. create texture first, and then use update.
But I find the pTexture is init failed.
it can run into this area, but m_texture still 0.
if I test only SFML, without QT code, it run correctly.
In init part. I write like this:
pimage = new sf::Image;
pimage->create(nWidth, nHeight, pdata);
pTexture->create(nWidth, nHeight);
pTexture->update(*pimage);
//int ret = pTexture->loadFromImage(*pimage);
pTexture->copyToImage().saveToFile("c:\\test5.jpg");
pimage->saveToFile("c:\\test6.jpg");
delete pimage;
pimage->create(nWidth, nHeight, pdata);
pTexture->create(nWidth, nHeight);
pTexture->update(*pimage);
//int ret = pTexture->loadFromImage(*pimage);
pTexture->copyToImage().saveToFile("c:\\test5.jpg");
pimage->saveToFile("c:\\test6.jpg");
delete pimage;
But I find the pTexture is init failed.
if (!m_texture)
{
GLuint texture;
glCheck(glGenTextures(1, &texture));
m_texture = static_cast<unsigned int>(texture);
}
{
GLuint texture;
glCheck(glGenTextures(1, &texture));
m_texture = static_cast<unsigned int>(texture);
}
it can run into this area, but m_texture still 0.
if I test only SFML, without QT code, it run correctly.
sf::Texture* pbackgroundTexture = new sf::Texture;
pbackgroundTexture->create(800, 480);
pbackgroundTexture->update(*pbackgroundImage);
//pbackgroundTexture->loadFromImage(*pbackgroundImage);
delete pbackgroundImage;
pbackgroundTexture->copyToImage().saveToFile("c:\\test1.jpg");
pbackgroundTexture->create(800, 480);
pbackgroundTexture->update(*pbackgroundImage);
//pbackgroundTexture->loadFromImage(*pbackgroundImage);
delete pbackgroundImage;
pbackgroundTexture->copyToImage().saveToFile("c:\\test1.jpg");

m_pThread->Init();
m_pThread->start();
void QUIThread::Init() {
m_pGECase = new GraphEngineCase;
m_pGECase->SetThread(this);

It is very strange, I rewrite the function in a test project(only have SFML), it can run correctly.
And I trace the code, when run copytoImage, m_texture can not get the pixels, so the pixels is empty.
What's happend??
std::vector<Uint8> allPixels(m_actualSize.x * m_actualSize.y * 4);
glCheck(glBindTexture(GL_TEXTURE_2D, m_texture));
glCheck(glGetTexImage(GL_TEXTURE_2D, 0, GL_RGBA, GL_UNSIGNED_BYTE, &allPixels[0]));

I start the SFML from a QT Thread, the window can popup correctly. But no Image display, and I trace the code, no error. How should I do?
I found after create the image from RGB data, that is right
pimage = new sf::Image;
pimage->create(nWidth, nHeight, pdata);
pimage->saveToFile("c:\\test6.jpg"); <---- right picture. size is 53518Byte
and then
int ret = pTexture->loadFromImage(*pimage); <---- ret is 1,
pTexture->copyToImage().saveToFile("c:\\test5.jpg"); <---- empty picture. size is 11111Byte
