Using this metaclass allows a class to inherit from both HasTraits and QObject. Using SuperQObject instead of QObject is highly recommended. See QtKernelManager for an example. cCsdxNt|ƒD]B\}}t|tƒr$||_q t |¡r t|tƒr |ƒ}||_|||<q Wt ||||¡}|S)N) rÚ isinstancerÚnameÚinspectZisclassÚ issubclassÚ MetaQObjectÚ__new__)Úmclsr ÚbasesÚ classdictÚkÚvZvinstÚcls©rú-lib/python3.7/site-packages/qtconsole/util.pyr s    zMetaQObjectHasTraits.__new__cCs$t ||||¡t ||||¡dS)N)r Ú__init__Ú MetaHasTraits)rr rrrrrr'szMetaQObjectHasTraits.__init__N)Ú__name__Ú __module__Ú __qualname__Ú__doc__r rrrrrrsrcsG‡‡fdd„dˆƒ‰ˆS)aÜ Permits the use of super() in class hierarchies that contain Qt classes. Unlike QObject, SuperQObject does not accept a QObject parent. If it did, super could not be emulated properly (all other classes in the heierarchy would have to accept the parent argument--they don't, of course, because they don't inherit QObject.) This class is primarily useful for attaching signals to existing non-Qt classes. See QtKernelManagerMixin for an example. cs&eZdZ‡fdd„Z‡‡fdd„ZdS)zsuperQ..SuperQClasscsˆ |¡}ˆ |¡|S)N)r r)rÚargsÚkwZinst)ÚQClassrrr =s  z#superQ..SuperQClass.__new__csZ|j ¡}xˆ ¡D]}| |¡qW| ˆ¡d}|t|ƒkrV||j|f|ž|ŽdS)Né)Ú __class__ÚmroÚremoveÚindexÚlenr)Úselfrrr!Zqt_classZ next_index)rÚ SuperQClassrrrDs   z$superQ..SuperQClass.__init__N)rrrr rr)rr&rrr&;s r&r)rr)rr&rÚsuperQ0s r'cCs6t |¡}t |¡}|dk r2| ¡|kr2t |¡}|S)a»Return a font of the requested family, using fallback as alternative. If a fallback is provided, it is used in case the requested family isn't found. If no fallback is given, no alternative is chosen and Qt's internal algorithms may automatically choose a fallback font. Parameters ---------- family : str A font name. fallback : str A font name.
