Member Function Documentation

◆ isNull()

bool QgsVariantUtils::isNull ( const QVariant &  variant)
static

Returns true if the specified variant should be considered a NULL value.

This method is more rigorous vs QVariant::isNull(), which will return false on newer Qt versions for tests like QVariant( QDateTime() ).isNull().

Since
QGIS 3.28

Definition at line 164 of file qgsvariantutils.cpp.

◆ typeToDisplayString()

QString QgsVariantUtils::typeToDisplayString ( QVariant::Type  type,
QVariant::Type  subType = QVariant::Type::Invalid 
)
static

Returns a user-friendly translated string representing a QVariant type.

The optional subType can be used to specify the type of variant list or map values.
