This pull request is a subset of #6490
This adds a new library for creation of applications based on Qt Quick
framework.
It contains reusable QML / Qt Quick components based on QGIS core
library.
The initial work introduces MapCanvas
To enable compilation of the library, use WITH_QUICK=TRUE
Further documentation of the library is located in doc/qgsquick.dox
For background information see the associated QEP:
qgis/QGIS-Enhancement-Proposals#109
The initial implementation is largely based on the work of Matthias Kuhn
and Marco Bernasocchi on QField probject - kudos to them for the great
job!
Introducting MDAL, QgsMeshLayer, mesh data providers (mesh_memory, mdal)
to read and visualize raw meshes: vertices and faces. Support dragging
2dm files from browser on canvas to visualize 2dm meshes.
Support for QgsMeshLayer in Python API.
* detect SIP version to add DefaultDocstringSignature directive
SIP doesn't handle any kind of preprocessing, so there's no better solution than configuring the SIP files from CMake.
SIP 4.19.7+ supports %DefaultDocstringSignature to prepend auto-generated Python signature to existing Docstrings
Because having it as a compiler flag means that when compiling a dependant application we need to have extra knowledge of this setting at compile time of the dependant application.
If this is not guaranteed (and the dependant application is compiled without QGISDEBUG while libqgis_core.so is compiled with QGISDEBUG) will result in different class definitions being found in header and library. For example for the optional QgsCoordinateTransform::mHasContext member. This in turn leads to crashes with funky traces and no chance to find out what's going on.
See description of QgsAuthCertUtils::pkcs8PrivateKey.
This fix may be needed on other platforms (untested at this point),
because Qt5 QSslkey class *still* does not directly support creation
using non-PKCS1 PEM- or DER-encoded data, though QCA, whose qca-ossl
plugin is linked to OpenSSL, does support PKCS1 and PKCS8.
In the style dock there is a new "3D View" tab - so far working just for polygon layers.
It is possible to select a polygon layer, enable 3D renderer and adjust its properties.
If a 3D Map View is open, it will be immediately updated (if auto-apply is enabled)
Very exciting! :-)
