In processing core every parameters can be optional but in scripts there is no way to define a parameter as optional and in modeler only layers can be optional.
For script, I propose a notation like output, if a parameter token starts with optional the parameter is optional.
For model, I propose to add the required combobox to all parameters.
This proposition does not change the value setter.
This proposition can fix the issue http://hub.qgis.org/issues/5488.
This is mostly so that algorithms executed in Processing scripts can
display messages in the same way as if they were executed directly from
Processing toolbox.
Also fixes a small issue with busy cursor being reset too early when
algorithms were executed from Processing scripts.
2ac5933 fixed the regression in 2.12, but there were more underlying
issues from <2.8 causing sub symbols with data defined properties
to be ignored.
Add some tests.
(refs #13707)
This introduces two new options to filter legend elements:
- filter by expression: a boolean expression can be set. Only symbols of
features that make the expression evaluated to true will be kept in the legend
- filter by polygon: only symbols of features that are inside the given
polygon will be part of the legend.
The polygon filtering is used in particular for a new option in the
composer legend that allows to filter out anything that is not included
in the current atlas polygon.
Not perfect, but good for a quick warning if a new class or member
has been added to the public API without Python bindings. The test
only considers the name of members, since it seems to be impossible
to test for the signature of a Python member. (So adding a new
overloaded method without bindings will still unfortunately pass).
You can avoid the test where bindings are not applicable:
- for a whole class by placing "@note not available in Python bindings"
in the class' Doxygen comments
- or by placing the @note inside a member's Doxygen comments for a
specific member
Additionally, classes which aren't included in the API docs
will not be tested.
