Turns out there is NO reliable way to create a proxy model
which adds new rows to a model, so just bite the bullet and
do it in the underlying model (yuck)
[feature] [mesh] #20731 add option to format time in mesh layer
There is new settings dialog that can be opened by button next to time slider. User can set reference time and time format (e.g. 2019-03-21 22:01:11).
This adds a new parameter type specifically for map scales,
QgsProcessingParameterScale. The values are evaluated using
self.parameterAsDouble, which returns the map scale
denominator (matching the standard in other parts of the
QGIS API).
Scale parameters are displayed to users using the standard
QgsScaleWidget, which includes the combo box of predefined
scales and a shortcut button to match the current map scale.
Returns a descriptive list of the possible string values acceptable
for the parameter.
E.g. for a QgsProcessingParameterVectorLayer this may include
"Path to a vector layer", for QgsProcessingParameterBoolean
"1 for true, 0 for false" etc.
For non-point geometry subclasses (points are always valid!) we
now cache the results of a geometry validity check. Subsequent
checks utilise the cached result wherever possible.
Because QgsGeometry/QgsFeature objects are implicitly shared, this
means that we avoid a *lot* of duplicate validity checks as
features and geometries are thrown around during processing model
execution.
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
