When running algorithms through the toolbox, which have dynamic
numeric parameters, add a data defined property override button
next to the widget so that users can set the overrides for these
parameters.
Previously this was available only in the backend, but not
exposed anywhere in the GUI.
Note that currently no algorithms support dynamic parameters,
so don't expect to see this everywhere. It's also only available
in toolbox/batch processing modes, not in models.
Without this change optional numeric parameters have no way to
be cleared in the GUI - they are always forced to have a value
Fixes#17471 - but I've noticed that many optional numeric
GRASS parameters have a non-null default value. These may
need to be investigated and manually changed to None defaults
in the description files.
Since these expressions were only evaluated immediately, it led to
confusing behavior for users who were expecting that the expression
would be applied per-feature.
Given that expressions can be directly entered into spin boxes, we already
have a way of users evaluating simple calculations for numeric
parameters at least.
I don't think there's a strong enough use case for needing to
calculate string results to leave the confusing expression builder
option in place.
This should be re-evaluated when we add UI support for dynamic
parameters (which are already supported in the backend), where
expressions are evaluated per-feature.
Fixes#17267
Contains variables for model parameters, algorithm results for
other child algorithms which are not dependent on the
algorithm.
Allows removal of final pieces of ModelerAlgorithm code
This commit restores some pre 3.0 processing behaviour for number inputs.
Now, if a number input is required outside of modeller than a spin box
will be shown instead of a free text input.
Clicking the expression builder button results in an expression
which is evaluated immediately to avoid users expecting that
the expression will be evaluated per feature.
* 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
