Texture.update() is not working

[LordNani]

It says Assertion failed: x + window.getSize().x <= m_size.x
 
Size and x\y are correct
It all breaks on last line. I need it for selection and copy/paste tool

        bufferRect.width = abs(curPos.x - point1.x);
        bufferRect.height = abs(curPos.y - point1.y);
        int width = bufferRect.width;
        int height = bufferRect.height;
        int x = bufferRect.left;
        int y = bufferRect.top;
        std::cout << "width is "<< bufferRect.width << std::endl;
        std::cout << "height is " << bufferRect.height << std::endl;
        std::cout << "left and top are " << bufferRect.left << " + " << bufferRect.top << std::endl;
       
        bufferTexture.create(width, height);
        bufferTexture.update(mainWindow,x ,y );

Since we don't know how rect.left is calculated, and you don't show the result of your std::cout lines, there's nothing very helpful we can do. Of course I tend to trust the assert more than you

Well, it was correct. The problem is that texture should not be created from part of the window. It is written in the documentation
