Thanks for you reply.
Create method exists but it's protected. From what I have been googling
around this is something new in Qt 5. Previous version seem to had this
method public. In order to access it, I have subclassed QWidget. In the
constructor of the window i'm passing the window ptr and casting it to
HWND. Then I use it within the create method, casted to WId.
The problem is that two windows are being created, thus, QWidget is not
taking over the give window pointer. Any ideas why this happen?
MyWindow::MyWindow(void* ptr) :
HWND w = (HWND) ptr;
// set black background
create((WId)w, false, false);
