Nope, it's like I explained before. Qt does all custom painting, it does not required the underlying 'native' widgets. They used to copy the look of OS's by manually drawing all controls. Since late 3.x or starting with 4.x (not sure which version) Qt under XP, Vista, MacOS X and GTK asks the corresponding component (via native API) to draw itself on a memory bitmap. Qt then paints that bitmap to the correct location on the form. This overcomes the issue when user install there own custom themes. Qt does not create a instance of the native widget. I believe this is similar to what LCL did a while back with XP theming in the themes (or whatever it's name is) unit.
