Description
int v = QDialogButtonBox::Ok | QDialogButtonBox::Cancel; QDialogButtonBox bb(QDialogButtonBox::Close); int index = bb.metaObject()->indexOfProperty("standardButtons"); auto prop = bb.metaObject()->property(index); bool ok = prop.write(&bb, QVariant(v));
produces
Qt 6.0.0 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 8.3.0) standardButtons isEnumType= true isFlagType true QMetaType(1046, "QFlags<QDialogButtonBox::StandardButton>", size=4, r egistered, flags=0x4/QFlags(0x4), data=0xe03bf58c6d7f0000) standardButtons QFlags<QDialogButtonBox::StandardButton>(Close) prop.write(int) false standardButtons= QFlags<QDialogButtonBox::StandardButton>(Close)
vs
Qt 5.15.0 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 5.3.1 20160406 (Red Hat 5.3.1-6)) standardButtons isEnumType= true isFlagType true prop.write(int) true standardButtons= QFlags<QDialogButtonBox::StandardButton>(Ok|Cancel)
This manifests as Qt Designer not showing QDialogButtonBoxes since the buttons are 0.
Note: It still works with enums (qtbug83689_enum.zip) ; at least this is inconsistent:
Qt 6.0.0 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 8.3.0) orientation isEnumType= true isFlagType false prop.write(int) true orientation= Qt::Vertical
