Another bit to make core library independent from QgsProject::instance().
Until now labeling engine configuration was taken from project singleton.
Removed legacy methods from QgsPalLabeling - the class now does not have
any more member variables/methods, it is just a bunch of helper functions.
(PR #4384)
A new class QgsPathResolver is introduced for conversion between absolute
and relative paths when reading/writing XML.
Cleaned up code in layer definition file support (.qlr) to better handle
relative/absolute path conversion.
This commit implements a new QgsAnnotationManager class, which
handles storage, writing and retrieval of annotations.
QgsProject has an annotationManager() attached to it. Map canvases
sync their visible QgsMapCanvasAnnotationItems to the annotations
contained within the project's annotation manager.
This moves all management, storage and retrieval of annotations
up to core and out of app/canvas.
* Save more data to QML
* Virtual fields
* Map tips
* Display expression
* Read only flag
* Streamline expression context generation
Whenever an object is able to generate an expression context it
implements the method createExpressionContext() declared in
QgsExpressionContextGenerator.
This makes a cleaner API and allows using QgsFieldExpressionWidget and
QgsDataDefinedButton from python because standard OO programming
approaches are used instead of callbacks and void pointers.
* Colorize output of doc and sip tests
* Fix build
* Fix sip complaints
* Fix rebase problems
* Workaround failing bindings test
This change consolidates more unit handling and conversion into
QgsUnitTypes.
Additionally, UnknownUnit was renamed to UnknownDistanceUnit.
All methods which accepted QGis::UnitType parameters have been
updated to take QgsUnitTypes::DistanceUnit instead.
ALso remove the unit handling methods toLiteral, fromLiteral, tr,
fromTr, and fromUnitToUnitFactor from QGis. Their corresponding
counterparts in QgsUnitTypes should be used instead.
- Conslidate doxygen in qgsproject.h
- Remove TODOs from docs, move to comments
- Cosmetic formatting changes to match QGIS standards
- Remove doxygen groups (we sort doxygen by name now)
- Clarified and improved some docs
- Remove mega outdated XML samples
ton of available area units (eg m2, km2, mi2, ft2, yd2, ha, ac,
etc)
Adds a new option in both the QGIS setting and project properties to
set the units used for area measurements. Just like the distance
setting, this defaults to the units set in QGIS options, but can
then be overridden for specific projects.
The setting is respected for area calculations in:
- Attribute table field update bar
- Field calculator calculations
- Identify tool derived length and perimeter values
Also adds unit tests to ensure that area calculated by attribute table
update bar, field calculator and identify tool are consistent wrt
ellipsoidal calculations and area units.
