Nice, but they didn't follow their advice in the case of creating parent-less widgets up to Qt4. I.e. in Qt3 and previous versions, creating a parent-less widget resulted in a window frame being created. Why was that? If I am creating a button I do not want a window frame around it. I am going to insert the button to another widget later. Thank God they fixed that in Qt4 and later versions.
