Widget Designer of QtCreator 14.0.0 generates wrong code for 'vertical spacer' with Qt 5.15.17

If a dialog contains a vertical spacer, an incorrect code is created in ui_????.h together with Qt 5.14.17.

Screenshot vertical spacer with QtCreator 13.0.2:

Created and compiled with QtCreator 13.0.2 and Qt 5.14.17:
verticalSpacer = new QSpacerItem(20, 478, QSizePolicy::Minimum, QSizePolicy::Expanding);
-> Correct

Created and compiled with QtCreator 14.0.0 and Qt 5.14.17:
verticalSpacer = new QSpacerItem(20, 478, QSizePolicy::Expanding, QSizePolicy::Minimum);
-> Wrong, parameter.  Parameter hPolicy and vPolicy are swapped.

The difference can be found in the file ???????.ui:

ui-File created with QtCreator 13.0.2:
<enum>Qt::Vertical</enum>

ui-File created with QtCreator 14.0.0:
<enum>Qt::Orientation::Vertical</enum>

It looks like the uic.exe from Qt 5.14.17 cannot handle the new ?????.ui file generated from QtCreator 14.0.0 correctly.

Possible solutions:

• QtCreator automatically recognizes that it is a Qt 5.x code and generates a correspondingly compatible ui file
• A setting for the QtCreator Designer that it generates Qt 5.x compatible code
• Bugfix for uic.exe of Qt 5.14.17
