Motivations:
- consistency - we generally use expanded names, and this also
matches Qt API which uses Database instead of Db
- avoids unpredictable capitalization throughout API (mix of "Db"
and "DB")
In some cases the render result for a layer may depend on more than
one layer.
This changes QgsMapRendererCache to use "cache keys" instead of layer ids
to identify images within the cache. When setting an image inside the
cache, a new list parameter is used to specify all layers on which
that image depends.
QgsMapRendererJob and subclasses are not designed to be subclassed
outside of core QGIS code. Marking them private API allows us to
change them after API is frozen again.
The basic idea is to split reading of XML definition and resolution of layer IDs into layers.
Also includes some cleanups in QgsProject and improvements in QgsVectorLayerJoinInfo.
Another bit in the project refactoring work to get rid of dependencies
on QgsProject singleton.
Reading of layer trees from XML is now split into two phases:
1. read XML and keep layer IDs
2. resolve layer IDs to QgsMapLayer instances (using QgsProject)
There are convenience methods to do both phases in one go.
Avoids confusing overload behavior when constructing QgsRasterLayers
from c++ code. This extra constructor was causing character literals
to be converted to a boolean loadDefaultStyle flag instead
of being used as the provider key. Removing the extra constructor
avoids this, and removes some duplicate code.
... rather than using QgsProject::instance() internally
These are small cleanups to dig out some instance() uses and move them one level up...
At some point we should maybe make labeling engine configuration a part of QgsMapSettings
and have default project labeling engine config accessible from QgsProject
in a way similar to e.g. snapping configuration.
These were not being used by QGIS code (always left at default 1.0
value), and removing them from the api allows us to simplify lots
of code. It also makes QgsRenderContext scaling much less confusing.
This method was used to sync the canvas layers to a composer map.
The logic has been moved to app to avoid a dependancy between
compositions and the main map canvas
This option will be used for more than just world file generation,
and instead will indicate which map should be considered the master
map for the composition from which any composer properties
calculating map units will derive the scale from.
Nothing particularly exciting here yet, but this commit
moves the definition of the provider base class to a c++
QgsProcessingProvider abstract base class.
As part of this some existing python methods were renamed
to make their use clearer and to fit with the QGIS c++
api conventions:
- getName was renamed to id
- getDescription was renamed to name
- getIcon was renamed to icon
These API breaks are documented
spell check will be done automatically in words by default (when some conditions are fulfilled)
possibility to avoid in words checking by adding :* at the end in spelling.dat
one can add #spellok at the end of a line of code to skip spell check on this line
