Adds a new checkbox at the bottom of each symbol layer's
properties which allows you to control whether the layer is
enabled or not.
Disabled layers are not drawn, but are saved and can be
enabled at a later stage.
This makes it easier to tweak symbol appearance without
having to totally delete a symbol layer.
The order of the elements is irrelevant and duplicate elements are unwanted. It
is therefore a perfect candidate for a set instead of a list. This prevents
filtering for duplicates manually be replacing some filer codes with (more
performant) builtin methods of QSet.
Groups nearby points into a single rendered marker symbol.
QgsPointDisplacementRenderer has been split into a new
pure virtual QgsPointDistanceRenderer base class which handles the
detection of clusters and grouping of points. The new cluster
renderer reuses this base class to avoid code duplication.
Additionally, some improvements have been made to the
displacement renderer, specifically:
- points are now assigned to the group which is "nearest" them,
rather then just assigning them first group within the search
distance. In some cases this was assigning features to a more
distant cluster, resulting in less predictable cluster patterns
- individual points are now correctly shown in their own
selection state
Lots of code cleanup + documentation too.

QgsSymbol::RenderHints QFlags value instead of a raw int
Also rename DataDefinedRotation to DynamicRotation since
it is no longer used for data defined rotation
These were unused (since they were moved to data defined properties
at the symbol layer level) and were not set anywhere in
core QGIS (ie, the only way to set them was by manually calling
this api)
Now the dialogs use a copy of the ramp, and the edited
ramp is retrieved by calling ramp() on the dialog after
it is executed.
Avoids pointer lifetime issues by storing and working
on a ramp pointer which the dialog does not have ownership
on.
Also fix a bunch of leaks relating to cloning color ramps.
QgsVectorColorRamp -> QgsColorRamp
QgsVectorGradientColorRamp -> QgsGradientColorRamp
QgsRandomColors -> QgsRandomColorRamp
QgsRandomColorRamp -> QgsLimitedRandomColorRamp
QgsVectorColorBrewerColorRamp -> QgsColorBrewerColorRamp
These color ramps are used throughout all of QGIS (not
just in vector symbology) and the current names are
misleading.
* Remove deprecated Qgis::WKBType and API cleanup
Renames QgsWKBTypes to QgsWkbTypes
Replaces usage of the enums:
* Qgis::WKBType with QgsWkbTypes::Type
* Qgis::GeometryType with QgsWkbTypes::GeometryType
Their values should be forward compatible (a fact that was already
explited up to now by casting between the types)
Renames some SSLxxx to SslXxx and URIxxx to UriXxx
* Fix build warnings and simplify type handling
* Add a fixer to rewrite imports
* The forgotten rebase conflictThe forgotten rebase conflicts
* QgsDataSourcURI > QgsDataSourceUri
* QgsWKBTypes > QgsWkbTypes
* Qgis.WKBGeom > QgsWkbTypes.Geom
* Further python fixes
* Guess what... Qgis::wkbDimensions != QgsWkbTypes::wkbDimensions
* Fix tests
* Python 3 updates
* [travis] pull request caching cannot be disabled
so at least use it in r/w mode
* Fix python3 print in plugins
And rename to QgsUnitTypes::RenderUnits. This enum is used in
much more contexts than just symbols, so QgsUnitTypes is a
better fit for it.
All methods which previously accepted QgsSymbolV2::OutputUnit
parameters or QgsSymbolV2::OutputUnitList parameters now take
QgsUnitTypes::RenderUnit or QgsUnitTypes::RenderUnitList
parameters respectively.
- rename methods with XML to Xml, CRS to Crs, WMS to Wms, ID to Id
- rename methods with SRS to Crs
- rename methods with abbreviations like "dest" to "destination"
- rename methods with abbreviations like "src" to "source"
color wheel in legend menu
Move embedded renderer handling to QgsFeatureRendererV2 and
add support for embedded renders to legend context menu
Fix#14967
Add methods to QgsRendererV2AbstractMetadata and QgsRendererV2Registry
to control renderer compatiblity by layer type. Should make it
easier to avoid this recurring bug popping up again in future.
Also add unit tests for QgsRendererV2Registry
Fix#14968
