QVision Widget Error upon compile

QVision Widget upon compile:

   To modify  the ui file outside of Qt Creator and delete the rows with ‘zorder’ tags. Then open it Qt Creator and compile and it appears any time.

Just try this initialize code:

<z-order>verticalSpacer</z-order>

      In  z-order tags, It use to delete the line with this tag, and rebuilt all.The z-order tags had fade from files. It must be a bug, but evidently one of little consequence; except the Qt spoiled.

Promoted widget-class is declared as “global include”:

The custom widget class is  “MyWidget” and the header is “mywidget.h” and the member widget  be named “myWidget”, the uic will orginate the code of the ui-class

#include <mywidget.h>
 
class qvvideoreaderblockwidget
{
public:
    MyWidget* myWidget;
 
   // ...
};
