Returns a reference to the simplest lossless representation of this geometry,
e.g. if the geometry is a multipart geometry type with a single member geometry,
a reference to that part will be returned.
This method employs the following logic:
- For multipart geometries containing a single part only a direct reference to that part will be returned.
- For compound curve geometries containing a single curve only a direct reference to that curve will be returned.
This method returns a reference only, and does not involve any geometry cloning.
configuration is set when changing a vector layer's style preset
This causes the layer styling dock to update before the layer's
new labeling settings are set, so the dock shows the incorrect
label settings for the previously used style
Fixes#42310
These utilities are used in a LOT of places in QGIS, but the
qgslayeritem.h include is a very heavy dependency. It makes sense
to have these utilities in a nice lightweight generic class.
class
This avoids an ugly include of qgsvectorlayerexporter.h in
qgsproviderregistry.h/qgsprovidermetadata.h, which in turn
triggers an inclusion of qgsvectorlayer.h and a bunch of
other heavy dependencies.
- Add enums to qgis.h instead of qgscoreenums, so that they belong to
a Qgis namespace
- Split up the various symbol headers into multiple files so that we
can fine-tune their inclusion and forward declare more readily, speeding
up recompilation
- Move QgsSymbol enums to qgis
file which is immediately deleted right after the QIcon creation
to store SVG icon content -- instead we need to place the svg in a
temporary folder which exists for the lifetime of the QGIS session
to QgsCoordinateTransform
QgsCoordinateTransform class can perform time-dependent transformations
between a static and dynamic CRS based on either the source OR destination CRS coordinate epoch,
however dynamic CRS to dynamic CRS transformations are not currently supported.
Using the same approach as the GDAL changeset in https://github.com/OSGeo/gdal/pull/3810
menu next to "Insert/Edit Expression…" in layout label properties
widget
When selected any dynamic parts of the label's contents will be
evaluated and replaced with their current values.
Provides an easy way to convert a dynamic label to a static one,
so that the user can then manually tweak the resulting tweak
when needed.
Fixes warnings like the following one with gcc 9.3

of the associated proj operation for a CRS
Allows callers to determine the projection used for CRS objects and
their details.
Also add QgsCoordinateReferenceSystemRegistry::projOperations() for
retrieving a complete list of all available PROJ operations
