This is the equivalent of std::as_const (which requires c++17) or
qAsConst (which requires Qt 5.7), neither of which we have
as minimum dependancies.
By wrapping implicitly shared Qt containers in qgsAsConst we can
safely use c++ for ranged loops instead of Q_FOREACH. (Since
Q_FOREACH's future is shaky)
See https://www.kdab.com/goodbye-q_foreach/ for further details
on why for causes a detach for Qt containers and why Q_FOREACH
is being removed from Qt.
Now that our minimum VS studio version allowed supports std::round,
we should use that in place of Qt's qRound method.
Because:
- it doesn't truncate to int, resulting in unpredictable
behaviour (refs #16925)
- better to stick to standard c++ methods wherever possible,
since they're likely better supported and optimised by the
compilers
- it's a tiny reduction to the barrier for entry to QGIS
development (I'm sick of pointing out the need to use
qRound during PR reviews!)
This change is being driven by:
- need for consistent terminology in the api. Currently there's
a confusing mix of border/outline used
- need for consistent terminology in the gui - we have a mix
of "border"/"outline"/"pen"
- bringing QGIS into line with the standard terminology used
in other graphic editing programs
* 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
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.
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
- update methods of existing classes
- add comment to methods missing in the sip bindings
- split up collective sip files into single files and use
same directory structure in python/ as in src/
- add a lot of missing classes (some might not make sense because of
missing python methods in those classes)
- remove some non-existing methods from the header files
- add scripts/sipdiff
- replace some usages of std::vector and std::set with QVector/QSet
- more API cleanups
- single click (instead of drag) to select a feature (fixes#1154)
- fixes for topological editing
