Introduce abstract QgsGpsToolsInterface and its subclass QgsAppGpsTools, which can be accessed via iface.gpsTools()
Deprecate existent GPS method in iface and move it to GPS tools.
QgsSipUtils.isPyOwned will return True if an object is owned
by python, or False if ownership is held by another object
or c++ class.
This gives a way to test in advance if we can safely assign
an object to a method which takes ownership (which always results
in a crash).
Deprecate old methods and make methods always take QgsSldExportContext.
Add capacity to QgsSldExportContext to collect export errors and
warnings.
The old API had no way to reliably report errors/warnings during
export to users.
With this new method code, it is now possible to use
`QgsProject::removeMapLayers` with a list of layers or a list of
layers IDs in qt5 and qt6.

Adds an API which an algorithm can implement to support auto-setting
parameter values. This is designed to handle the case
of eg an algorithm which does a file format translation, where
it's desirable to default the output parameter value to an input
parameter value with a different extension.
This can now be done by implementing autogenerateParameterValues
in the algorithm, eg:
def autogenerateParameterValues(self, existingParameters, changedParameter, mode):
if changedParameter == self.INPUT:
input_file = existingParameters.get(self.INPUT)
if input_file:
input_path = Path(input_file)
if input_path.exists():
# auto set output parameter to same as input but with 'qgs' extension
return {self.OUTPUT: input_path.with_suffix('.qgs').as_posix()}
return {}
Works for both toolbox and batch modes for algorithms
Improves the appearance of labels in situations like road networks,
where things like dual carriageways, service roads, etc can result
in many labels of the exact same text appearing close to each other.
When active, removes any labels with the exact same text (case
sensitive!) which are closer then this minimum distance.
The setting applies across layers, so duplicate text from ANY
layer will be considered.
Fixes#61476 / #61493
The analysis of DescribeFeatureType response with the GMLAS driver makes
appear fields that are not supported by the
addFeatures()/changeAttributeValues() method. So if transaction support
is detected and featureMode=default, use QGIS built-in analyser to get
SimpleFeatures only. Otherwise try the GMLAS method.
