The Qgis class provides global constants for use throughout the application.
Definition: qgis.h:54
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition: qgsfeedback.h:44
Base configuration for geometry checks.
This represents an error reported by a geometry check.
virtual QMap< QString, QgsFeatureIds > involvedFeatures() const
Returns a list of involved features.
virtual QString description() const
The error description.
virtual bool isEqual(QgsGeometryCheckError *other) const
Check if this error is equal to other.
virtual bool closeMatch(QgsGeometryCheckError *) const
Check if this error is almost equal to other.
virtual QIcon icon() const
Returns an icon that should be shown for this kind of error.
virtual bool handleChanges(const QgsGeometryCheck::Changes &changes)
Apply a list of changes.
This class implements a geometry check.
QMap< QString, QMap< QgsFeatureId, QList< QgsGeometryCheck::Change > > > Changes
A collection of changes.
QFlags< Flag > Flags
CheckType
The type of a check.
A layer feature combination to uniquely identify and access a feature in a set of layers.
An error of a QgsGeometryOverlapCheck.
const OverlappedFeature & overlappedFeature() const
Returns the overlapped feature.
Checks if geometries overlap.
ResolutionMethod
Available resolution methods.
@ Subtract
Subtract the overlap region from the polygon.
QList< Qgis::GeometryType > compatibleGeometryTypes() const override
A list of geometry types for which this check can be performed.
QgsGeometryCheck::CheckType checkType() const override
Returns the check type.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:162
A class to represent a 2D point.
Definition: qgspointxy.h:60
Represents a vector layer which manages a vector based data sets.
