Changes in the layer API:
* The setDatasource() methods become non-virtual public method
* The virtual private setDataSourcePrivate() method is defined and the provider setDataSource implementations have been moved to this new virtual method
The trust flag at the projetc level is only used to read vector layer extent from xml, not from provider.
This flag was not available at the vector layer and data provider level.
We propose a new QgsMapLayer reading flag to propagate the trust layer metadata prohect's read flag an d a new provider options to trust datasource config.
Trusting the datasource config means that the provider can use estimated metadata, the primary key is unique and the detectable geometry type and srid are the same as the requested.
Also
* in settings UI, add a 'Early resampling' checkbox
* in raster properties UI, add similar checkbox
* serialize/deserialize new settings in QgsRasterLayer XML
CRS validation, regardless of the user's settings
This avoids hacks put in place in other parts of QGIS code or in plugins
to temporarily deactivate the CRS validation prompt, providing a supported,
stable method to indicate that when loading a particular layer no CRS
validation is required.
The extent reported by raster layers may be smaller than the area
which can be rendered.
Notably for WMS with symbology that takes more space than the data.
Fix#30251
Adds a new visitor pattern API for creation of visitors which visit
all the style entities (symbols, color ramps, text formats, and
label styles) associated with different objects. Can be used on a
renderer, map layer, or project wide level.
E.g. on a project wide level, allows collection of ALL the style
symbols/color ramps/text settings inside a project, including those
in layouts or annotations!
not working yet, just set the menu entries
QgsMapLayerStyle::StyleCategory has moved to QgsMapLayer to avoid making QgsMapLayerStyle a QObject and they are mostly used in QgsMapLayer
- baseName is just passed on to the parent constructor to be the display
name, use a literal string in the example to avoid misunderstanding.
- Remove stray bullet.
